MBTI: Lenore Thomson's Descriptions of Types
This set of profiles is incomplete and covers only 12 out of 16 types: INxJs, ISxJs, IxFPs, IxTPs, ENxPs, and ExFJs.
INFJ
“Because INFJs use Fe to relate to the outer would, they may seem more outgoing than they really are. Their personal approach and ability to find common ground with others combines with their intuitive need for innovation and alternative views, and they frequently find themselves in positions of authority. They may not seek leadership, but they are often elected by others to serve on boards and committees. People appreciate their ability to listen and to consider group feelings and values” (246).
“Thus, it should be recognized that INFJs and more like INTJs than they initially appear. Their primary relationship is to their inner world, and they are receptive to others only up to a point. Indeed, these types often find that their sympathy and perceptive listening have been mistaken for an overture of friendship, which they didn't intend” (246).
“Unlike INTJs however, their sense of the unexpressed is not impersonal and casual; it is intensely personal and oriented by emotional awareness. Their intuition takes them into psychological areas that other types are likely to keep at bay. Because they don't usually know right away the import of what they're intuiting, they may ‘go along’ with a questionable situation until they can get a hold of how they actually feel about it. This tendency can be confusing to others, and it is often misinterpreted as reckless experimentation” (246).
“Like INTJs, INFJs have a penchant for abstraction and symbolic representation. If interested, they excel in the fields of science, math and medicine. However, they are not generally motivated by sheer intellectual challenge. INFJs require a sense of meaning in the work they do. They are more likely than INTJs to personalize their skills - as teachers, psychologists, consultants, ministers and family doctors. They are particularly sensitive to others' feelings of exclusion, and they may address or try to rectify inequities of status or opportunity within the context of their profession” (246).
“Such types can be quite tenacious in pointing out the discrepancies between stated beliefs and actual behavior. This is the arena in which their intuition is most evident. INFJs wrestle all their lives with the conflict they perceive maintaining harmonious relationships and expressing emotional truth, and it is a central issue in the books, novels, plays, and psychological articles that INFJs write. Their 1 percent representation in the population belies the tremendous influence these types have in shaping cultural ideas about identity and being true to oneself” (247).
“INFJs are exquisitely sensitive to nuance and suggestion - all the ways we unwittingly express how we feel, who we are, what we believe about ourselves and others. They are not interested in the precision of language, as INTJs are, but in its rich possibilities for metaphor and multiple layers of meaning. They often have a gift for verbal imagery or poetic expression, and they are sometimes capable of raising to consciousness something that others can only dimly sense” (247).
“INFJs frequently express themselves indirectly, depending on unstated implications to carry their meaning, and they can be put off by too direct a reference to something that is of great value to them” (247).
“Because INFJs are so alert to the unsaid, they may find it difficult to sort out their own emotions from the mood and feelings they discern in others. Young INFJs, in particular, are sometimes labeled hyper-sensitive or melodramatic, because their self-experience is tied to others emotional boundaries” (248).
“Optimally, they bring their emotional insights into the community as art, or they use them to help others come to terms with conflict in their own lives. INFJs are also capable of turning their inner experience into trenchant social commentary - by finding their truest voice and using it, perhaps in the ministry, or in the kind of edgy comedy of a Richard Pryor. Types who do this can become a potent focal point for others' unexpressed fears and yearnings. However, the pressure of speaking one's own truth in a public forum is ultimately taxing for most INFJs” (248).
“The INFJs sense of physical well-being is very much allied with their relationships and emotional investments. They want very much to be liked, buy they're afraid of being hurt, and they often develop a sense of humor that helps them to maintain a wide range of friendly contacts. Such types are by turns highly sociable and maddeningly inaccessible” (248).
“INFJs have to find some way to sort out their feelings from the feelings of others - in not in writing or art, then in an expression of religious faith, or the effort to help others to express themselves” (249).
“Like INTJs, INFJs have a tendency to use their secondary function for protection - for example, to distance themselves from a relationship that demands too much of them emotionally. They are entirely capable of meeting the expected surface demands of a situation, all the while nursing secret criticisms of a partner or a friend” (249).
“In general, these types do create their own reality, and it is one of great riches - a storehouse that artists, poets and writers draw from for their material. However, if their inner life is not balanced with reality, they may feel so different from others that they become self-conscious and defensive. They may be drawn to dysfunctional people, romanticizing their ability to see something in them that others cannot see” (250).
“INFJs are a bit like Merlin, summoned by the voice of Nimue deep with the enchanted forest. The song they hear is calling them elsewhere, beyond the cultivated borders of common consensus. When they are able to use their Extroverted Feeling function well, they bring that song back into the public domain, find a way to integrate it into the fabric of the community. INFJs who don't do this can get trapped, like the great wizard of Camelot, in a kind of enchantment that robs them of their very genuine powers of discernment and insight” (250).
INTJ
“Because INTJ’s rely on Extraverted Thinking for their dealings with the outer world, they often have a scientific, somewhat skeptical approach to reality. They want to know how things work and what they’re likely to do under varying circumstances. Impatient with wasted motion, words, and emotion, their outward demeanor may be difficult to read” (239).
“Indeed, an INTJ’s bearing can seem downright Vulcan. The Vulcans, of course, are a fictional people in the Star Trek series – resolute logicians who barely change expression or use body language, even when they’re puzzled or aware of danger. Thus, one might heed the words of Tuvok, the Vulcan tactical officer on the spaceship Voyager, who warns: “exterior composure is no indication of a Vulcan’s inner state” (239).
“Although they superficially resemble Extraverted Thinkers, INTJs are always guided by their Intuition. They are rarely committed to general assumptions about rules, laws, and hierarchy, and they may have an acerbic sense of humor about such things. INTJs will use what works in the service of their ideas; and they will quickly discard or change what doesn’t” (240).
“A (probably apocryphal) story tells of a delegation of sailors who went to the tribunal of the Inquisition in the seventeenth century, when the Catholic Church had forbidden the use of Galileo’s astronomy as an affront to the Bible’s account of creation. The sailors sheepishly confessed that Galileo’s theory had both simplified their journeys and made their maps more accurate. They hoped that the Inquisitors would exempt mariners from the church’s proscription against it. The Tribunal considered the problem, consulted with the bishops, and sent an emissary to the Pope. Finally, they conceded. They said, “OK, if the theory works, use it. But don’t believe it”. This is a pretty fair description of the INTJ’s basic attitude. Fundamental truth is something different from expressed knowledge, which is always a fiction of one sort or another. If a theory works, it doesn’t matter who supports it or what anyone thinks it means. If it doesn’t, why bother with it?” (240).
“Although both INTJs and ENTJs realize their Intuitions by way of rational criteria – principles, law, organizational structure, and so forth – ENTJs will not usually pursue a goal unless it strikes them as compatible with reason. INTJs are more classicaly Promethean. They will steal fire from the gods without any assurance that a reasonable hearth exists at which to tend it back home. For such types, knowledge is not information, but a way of looking at things” (240).
“Consider James Hillman’s understanding of the soul as ‘a perspective rather than a substance, a viewpoint toward things rather than a thing itself’. This is a typically INTJ antidefinition. Such types may expend a great deal of time attempting to winnow the actual logic of accepted theories and formulations from expedient or merely limited assumptions. INTJs are accordingly drawn to science, mathematics, and medicine – fields in which new ideas about reality are constantly being forged and tested logically. They may also take interest in psychology, theology, publishing, and linguistics. As they pursue their intuitions, they inevitably combine elements from varied fields, perceiving an underlying commonality of form or meaning” (240).
“This sense of underlying structure and meaning leads INTJs to value both elegance of form and subtlety of expression. Nothing exists that can’t bear reediting and paring down to its essential components. The connections INTJs perceive among very different areas of knowledge may be sufficient to convince them they’re headed in the right direction, even when they can’t explain what they’re after” (241).
“Like the ISTJs, INTJs cannot accept new information until they relate it to their inner world. However, ISTJs analyze new data by aligning it with what they already know. Once they’ve accepted a fact, it becomes part of their identity. INTJs explore information largely by rejecting its influence – examining it from other perspectives and determining its limitations” (241).
“Because this inner process is tied to their sense of self, INTJs can take a long time to figure out ‘who they really are’. Their need to find out ‘what’s missing’ from a system of information invariably takes them into their own mental world – to an imaginative reconstruction of ideas – and the effort necessarily becomes a search for part of themselves. Such types can develop the destructive habit of formulating their identity in terms of their ability to see a situation’s limits, needing to find the flaws that will allow them to become spectators rather than performers” (241).
“For this reason, others don’t usually recognize the need of the average INTJ for external structure. INTJs are invariably described as independent and self-motivated, and this is certainly true with respect to their strongest functions. Where technical and intellectual competence are concerned, INTJs have a kind of inner compass, and they prefer a situation in which they don’t have to coordinate their work with or report to someone else” (241).
“Moreover, they don’t take criticism of their ideas personally. Position, title, and reputation have no meaning for these types. They will not entertain another’s judgment of their worth unless they believe the person intellectually qualified to make the assessment. And even a legitimate judgment will usually strike them as an indication of the other person’s assumptions and expectations” (241).
“Personal relatedness, however, is a different matter. INTJs are much less confident in a purely social situation. It is no exaggeration to say that their primary relationship is to their inner world, and they will nurture that relationship at the considerable expense of social abilities and the art of compromise” (241).
“In a field that excites and interests them, they are often driven, and they tend to expect the same degree of investment from subordinates. They frequently convey impatience when a situation that had seemed impersonal and outwardly predictable suddenly requires free-form personal interaction” (242).
“INTJs don’t like to say something more than once, and they may cut others short when conversation strikes them as unnecessary. Moreover, their need to find an alternate point of view in order to understand something can sound like disagreement or negativity – as though the speaker’s ideas had been judged and found wanting. Thus, even people who know an INTJ well may believe the person is either indifferent to them or critical of them” (242).
“INTJs can also be lonely behind their reserve, not knowing how to fit in even when they want to be included. This aspect of the type is partly the result of the INTJ’s comparative rarity. At 1% of the population, INTJs are usually the only one of their kind in a family. Throughout grammar and high school, they are often the only such type in a classroom” (242).
“Although this ratio changes at the college and graduate level, when INTJs specialize in fields that appeal to other INJs, for most of their developing years, these types have good reason to feel different from others. Because they relate to the outer world with Extraverted Thinking, they generally interact by trying to determine the logical relationship of others’ views and demands to their own needs. Consequently, they get little experience in areas of relationship that don’t interest them” (242).
“Many such types become articulate quite early, and they use their verbal abilities to fend off involvement in anything they don’t understand or don’t wish to. However, their awareness of others’ feelings does not keep pace with their verbal abilities. Young INTJs may be intellectually precocious but emotionally immature, exercising their dominant function by distancing themselves from others, engaging in ironic comments and somewhat juvenile sarcasm” (243).
“Sometimes, to their surprise, their observations make people laugh and afford them the group approval they were attempting to preempt. INTJs rather enjoy the paradox this sets up and will play to it – experimenting with the boundaries of humor itself. One might consider comedian Dennis Miller, who presents himself as a caustic observer and occasional saboteur of the images and conventions on which his livelyhood depends” (243).
“Like all types, INTJs resist their least-developed functions and attempt to avoid situations in which they’ll come into play. It should be granted, however, that Sensation and Feeling, the INTJ’s weakest functions, cannot be avoided wholesale in the course of a normal human life. These functions are our means of concrete embodiment – our physical pleasures and desires, our emotional connections with others, our love of home and hearth, our sense of being grounded and real” (243).
“INTJs appreciate these things well enough, but more in the abstract than in the messy realities of everyday existence. Regarding most events as arbitrary arrangements of elements, to be dismantled and reassembled at will, they may find it difficult to assume the duration of another’s affection or interest in them” (243).
“In general, these types deal with feelings the way they deal with ideas – by formulating and explaining them to themselves so they know what to expect, or getting far enough outside them to resist their influence. In an INTJ’s mind, friendships require a particular kind of investment; sexual connections another; marriage another. Such types want to know which category they’re dealing with before they get involved” (243).
“But real relationship is unpredictable, and real people resist the categories the INTJ attempts to apply. In fact, sexual attraction and romantic infatuation usually catch these types by surprise. And although they enjoy the distinct pleasures of sensuality, the careening roller coaster of emotions that comes with the territory ultimately forces them to use their inferior functions” (243).
“As opposed to their usual view of reality as arbitrary, they begin to experience the influence of primitive Extraverted Sensation and feel an anxious sense of material possession. They feel impulsive, out of control, and unable to take anything for granted. They worry that their intellectual life will never get back on track until the relationship becomes more ordinary and settled. Ultimately, they attempt to regain control – by pressing for declarations and permanency, even if their own intentions aren’t clear to them yet, or by using their critical judgment to distance themselves from their emotions” (243).
INTJs appreciate the security of a committed relationship, and given the ration of Extraverts to Introverts in our culture, often marry Extraverted types. They enjoy their families and maintain an unusual respect for the individuality and independence of both spouse and children. However, they may not sustain the kind of Extraverted interaction their partner expects.
“They’re more likely to settle in and, at their first opportunity, reassert their primary relationship to their inner world. This is true of both male and female INTJs. When there is too much outer stimulation or conflict, INTJs lose touch with their intuitive process and become restless, bored, and emotionally exhausted. Thus, INTJs need a fair amount of time alone” (244).
“They also need a fair amount of intellectual challenge and exercise. If a partner can’t provide it, INTJs are likely to seek it privately or with others. The same INTJ who gets bored at parties and looks around for the nearest bookshelf may well forget to eat or sleeping when involved in a complex and intricate conversation about ideas. In fact, for an INTJ, the communion of like minds is a kind of cerebral analog to falling in love” (244).
“INTJs may even resist concomitant physical attraction to a kindred spirit for fear of compromising the relationship with the exigencies of chemistry and social expectation. Such types frequently envision an ideal way of life that would unify NTJ cerebralism with SFP physical immediacy, but in actual practice, they are most likely to understand such unification as something ultimately spiritual. For this reason, INTJs may have an abiding interest in Sufism, or the Buddhist warrior philosophy, or the kind of mystical poetry that celebrates this idealized state in language” (245).
“Ironically, INTJs can best engage their Feeling and Sensate qualities by developing more Extraverted Thinking. The inner world of an INTJ is so compelling that such types can let their physical and emotional needs go for long periods of time. Deliberate use of Extraverted Thinking gives them more of what they need – a sense of rootedness in the material world: the world of bills, train schedules, medical and dental appointments, shoe repair, and the like. As the Zen Buddhists are wont to say, ‘after ecstasy, the laundry.’
“Extraverted Thinking also connects them to the assumptions and expectations of others, so they are better able to analyze people’s expressions and behaviors for social cues. Many INTJs find, for example, that their career ambitions push them into developing a serviceable repertoire of behaviors that convey goodwill and put people at ease. Ultimately, these behaviors are more predictable than the abstract categories of relationship INTJs are inclined to devise” (245).
“When Extraverted Thinking isn’t working well enough, INTJs draw directly from their tertiary function, Introverted Feeling, which merely rationalizes and supports their worst tendencies. It encourages them to idealize their abstract ideas about life and to avoid real relationships as unworthy of their investment. Such INTJs are often credited with staying above the emotional fray of life, when they have actually never been in it” (245).
ISFJ
“Like ISTJs, ISFJs, are most comfortable with facts and information about concrete reality. However, where ISTJs organize and apply what they know impersonally, preferring numbers, schemes, or logical premises, ISFJs relate to the outer world in a decidedly personal way, with Extraverted Feeling. ISFJs are highly alert to behaviors and gestures that suggest another’s emotional attitude, needs, or expectations, and they generally acquire knowledge that allows them to be of service—preferably to one person at a time.” (p.191)
“For this reason, many ISFJs are attracted to social work, pastoral counseling, nursing, or family medicine—fields in which they excel because they can concentrate on the needs and problems of individual clients. However, like all Introverted Sensates, ISFJs are good at following procedures, and they may have a flair for research and statistics.” (p.191)
“Thus, they are sometimes attracted to more technical fact-based occupations—for example, in library science, biometrics, computer programming, engineering, or insurance. Even in these cases, ISFJs tend to personalize what they do, using their skills on behalf of an employer, an administrator, or a customer: someone who needs their assistance and expertise.” (p.191)
“Indeed, ISFJs are so focused on others’ goals and expectations that they can sem literally selfless, without a full personality of their own. Support staffs throughout business and industry are made up of these types, who function almost invisibly, in the background of an organization, implementing decisions made by others. For this reason, it may be difficult to appreciate the Extraverted Feeling nature of an ISFJ’s expectations.” (p.192)
“Like the Extraverted FJs, ISFJs need to feel needed. They have a hard time saying no, even when they’ve taken on more obligations than they can readily handle. Moreover, like EFJs, ISFJs need personal feedback. They want their efforts to matter to someone. In this ISFJs are often disappointed, owing, in part, to their self-effacement. Their tendency to shrug off what they’re doing as no more than any decent person would do under the circumstances ensures that they are usually taken for granted. Their Introversion also contributes to the problem.” (p.192)
“Extraverted FJs are drawn to roles and commitments that reflect prevailing social values, which assures them of feedback in predictable terms. ISFJs are more subjective in their motivations. Their behavior is dictated not by their social role—as a good parent, citizen, employee, and so forth—but by their self-experience as a helper, rescuer, or nurturer. Most ISFJs find that they are drawn to and attract individuals who need them wherever they go. Moreover, the response of an ISFJ to another’s need is immediate, dictated entirely by the other’s situation.” (p.192)
“ISFJs will go out of their way to help a family member in trouble, a misunderstood coworker, or a perfect stranger sitting next to them on a bus. They rarely consider the amount of time or effort their involvement will require—or even the potential consequences of their actions. They may find it difficult to justify, or even to verbalize, their fundamental motives, but they are quite certain they are doing the right thing and will not be swayed from their perceived task.” (p.192)
“For this reason, ISFJs can seem stubborn, even when their behaviors are demonstrably selfless, or unable to appreciate people who aren’t in some way dependent on them. They may react to signs of a person’s independence as a kind of betrayal, which leads to their feeling jealous and possessive of the people they care about.” (p.192)
“ISFJs are puzzled or hurt when others bring this aspect of their behavior to their attention. They don’t experience themselves as strong or controlling. If anything, ISFJs see themselves as too “easy,” too influenced by others’ opinions, too eager to please, too scattered, unable to decide when to take a stand and when to give in.” (p.193)
“This self-experience derives, in part, from the ISFJ’s other-oriented basis for decision making. ISFJs are both firm and decisive when they’re in a one-to-one situation—such as caring for a patient or carrying out an employer’s wishes—because their behaviors are being guided by the other’s immediate needs.” (p.193)
“In a group situation, however, or in a position of general authority, ISFJs often feel unsure of their position until they know how others in the group will be affected. They resist making plans that appear to give their own needs precedence. For example, ISFJ administrators may find delegation difficult—as though it were an admission that they need help—and they can end up doing all the work themselves.” (p.193)
“The ISFJ’s preference for basing decisions on others’ needs or wants is magnified by the length of time it takes this type to process sensory information. ISJs in general have a difficult time with Extraverted Intuition—“taking in the big picture.” They want a concrete grasp of all the details before they’re satisfied they understand what’s at stake in a situation. If they’re listening to a story, for example, and a minor point doesn’t make sense to them, they may spend all their time trying to get that fact straight before they can react to the story’s other implications.” (p.193)
“Consequently, most ISJs experience a certain degree of pressure from other types to make decisions before they’re prepared to do so. Although this poses a problem for ISTJs, their grounds for appraising external demands are impersonal and logical, and they may insist on taking the time they need. ISFJs, however, take others’ reactions and expectations to heart, and they may end up offering approximate information rather than taking the time to think out what they know.” (p. 193)
“The constant experience of people pushing them to make up their minds and then correcting their facts can encourage the type to develop an inaccurate self-image as inadequate or not smart enough, and they may defer to an external authority or go along with others rather than process facts and information to their own satisfaction. They’re constantly wrangling with themselves over their need to be true to themselves and their desire to maintain interpersonal harmony, and they sometimes wonder if they’re simply rationalizing thir inability to stand up for their rights or beliefs.” (p.194)
“Like ISTJs, ISFJs have an idiosyncratic view of reality, but they don’t recognize how individual their perspective really is. Their comments and observations often precipitate reactions from others that surprise them. ISTJs, in the inimitable way of most TJs, are hurt by rejection, but generally conclude that the problem is with other people’s intelligence. ISFJs are more likely to be wounded by an unsympathetic response, and they’re inclined to conclude that their opinions aren’t good enough or worth voicing.” (p.194)
“In fact, many ISFJs develop a self-deprecating sense of humor—intended, presumably, to beat others to the punch. Where ISTJs will comment on the little absurdities of life, as much for their own amusement as for that of others, ISFJs will call attention to their own foibles—as it where, telling on themselves.” (p. 194)
“For example, an ISFJ nursing administrator, talking about an upcoming trip, claims that she has to pack three suitcases, even for a weekend, because she’s never sure exactly what the weather is going to be and wants to be prepared for every possible contingency. This is a good illustration of the ISJ’s constant need to control discontinuity perceived between inner expectation and outer reality, but it also illustrates the way ISFJs will turn the humor of the situation back on themselves.” (p. 194)
“ISFJs can become overly dependent on others’ ideas about what’s appropriate in a situation, especially if these ideas coincide with their own ideas about integrity and commitment. For example, they may find it difficult to approve of those who don’t behave or dress appropriately for their social position. Extreme types can place a great deal of weight on social signs and signals of all sorts. Like ISTJs, they may believe that men and women should comport themselves quite differently from each other.”
“In the best of all possible worlds, ISFJs prefer to have a clear and concrete understanding of what is expected of them. Once they have all the details in order, they will follow through on their obligations conscientiously and exactingly. It should be said, however, that most ISFJs overestimate the expectations that anyone actually has of them. They seem to believe that worth accrues to any pursuit only by “going the extra mile.” (p.195)
“Like all ISJs, ISFJs may stay too long in a situation, out of loyalty or commitment, even when their potential is being limited or squandered. This kind of dedication can be a genuine virtue, but it can also indicate that Extraverted Feeling isn’t doing its proper job in the ISFJ configuration. ISFJs tend to use this function only to link the objective needs of others to their self-experience as helpers. They need to learn to train it on themselves and to assess their own needs and goals in outer reality.” (p.195)
“When ISFJs become too dependent on Introverted Sensation, they have no way to assess the worth of their investment in a situation. Instead of using Extraverted Feeling to balance their viewpoint, they may turn to their tertiary function, Introverted Thinking, for support in their accustomed behaviors.” (p.195)
“Introverted Thinking can, under such circumstances, convince the ISFJ that his or her actions are part of a much larger scheme whose integrity must be maintained self-sacrificially—the future of the children, the survival of the much-admired employer, the Christian way of life. ISFJs are often praised for their loyalty to lost causes, but they can actually use this proclivity to avoid real intimacy.” (p.195)
“For example, such types can become accustomed to relationships in which all emotional risks are taken by the other, and the ISFJ’s own weaknesses and problems remain private. Indeed, some ISFJs unwittingly undermine the efforts of others to become independent for fear of losing the relationship, and they can make serious romantic mistakes—choosing partners who are likely to keep them in a service-oriented role. They may have a difficult time with stories or movies that don’t end happily and in favor of emotional commitment.” (p.195)
“Like ISTJs, ISFJs enjoy an exchange of acquired facts, and they will warm to their subject in the presence of a receptive listener. And like ISTJs, ISFJs are often interested in outdoor activites—hiking, camping, swimming, hunting, fishing, and so forther. As with all activities that matter to them, ISFJs acquire the facts, equipment, and expertise their pursuit requires and take seriously the rules and behaviors that govern its performance.” (p.195)
ISTJ
“ISTJs are so task-oriented, and so conscientious in their handling of details and standard procedures, that they are often stereotyped as “establishment” types, weighed down by the gravity of institutional priorities. Although ISTJs are indeed careful, and concerned to preserve what has been proved to be worthwhile, these characteristics are only a part of the type’s approach to the world—the part that most people see. ISTJs are fundamentally Introverted Sensates, with a highly subjective, original turn of mind.” (p.186)
“As Introverted Sensates, ISTJs are unparalleled realists. However, they don’t concern themselves with external reality as such. They relate to facts about external reality, and largely by way of the mental constructs determined by Extraverted Thinking: words, numbers, schemes, diagrams, hierarchies, methods, and codes of conduct.” (p.186)
“Moreover, outward predictability is important to the only in so far as events and experiences involve their primary interests and emotional investments. For example, an ISTJ may be exacting about taking lunch at the same time every day, but oblivious to the clutter of books and papers on the desk or living room floor.” (p.187)
“The very selectivity of the type’s sensations give ISTJs an extraordinary capacity for detail in the areas that strike them as important. Where date and figures are concerned, ISTJs are painstakingly thorough. Such types make persistent, informed, tough-minded finance officers, prosecutors, engineers, administrators, researchers, accountants, psychiatrists, professors, trustees, and the like.” (p.187)
“Their powers of concentration are unequaled—and nothing escapes their attention, whether they’re preparing a contract, assembling materials for a seminar, calculating a mortgage, repairing an electrical system, researching a legal precedent, or making sense of medical statistics. They prefer to work in an uninterrupted manner, and they are patient with routine undertakings that other types might describe as tedious.” (p.187)
“Their capability and reliability in this respect often results in their attaining a position of administrative power. ISTJs oversee and supervise departments in far more organizations and institutions than their 6 percent representation in the population might suggest. They take their authority seriously, are always ready to solve a problem, and are scrupulous about their responsibilities. However, they may be perceived as emotionally distant and demanding.” (p.187)
“They don’t always understand what people want of them, and they may be uncomfortable and awkward about conveying warmth apart from a situation of personal intimacy. Although they enjoy socializing, especially the kinds of rituals and holidays that bring family and friends together, like Introverts, they need a fair amount of tie to themselves.” (p.187)
“Privately, ISTJs are usually observing the world with a kind of detached irony. Their inner expectations are frequently contradicted by outer reality, and the incongruity would be exasperating if they took it too seriously. Made aloud, their observations are both pointed and funny, but they are also unexpected and sometimes have an “out in left field” quality. Most ISTJs don’t share their private considerations with others unless they feel at home and among friends. Experience usually teaches them that their reactions to a situation are not necessarily the ones that others are having.” (p.187)
“Indeed, ISTJs are not very well understood. Because they tend to be low-key sorts, responsible, and reluctant to make a change in an outward situation until they’ve considered all its ramifications, they can strike others as overly cautious and unyielding workaholics, without much color. ISTJs themselves are inclined to take their own skills for granted, as though they were doing no more than following through on their commitments. Oh, well, they say, a diamond is just a piece of coal that stuck to its job.” (p.188)
“It should be recognized, accordingly, that ISTJs are not just conservators and loyalists. They are masters of gradual, almost imperceptible modification. They tinker here, shore up there, solve problems and rectify ambiguities, all the while preserving the best of what exists, scarcely recognizing that in the process, they’ve adapted form quite brilliantly to function. They can accommodate the requirements of a job so perfectly to their own strengths that the systems they create are unique and difficult to pass on to their own successors.” (p.188)
“It should be noted that ISTJs are most decisive when they’re organizing things for other people. Such types can find it difficult to limit and organize the data of their own mental world without an external reference point to guide them. For example, they may over estimate others interest in a project. Given no specified limits, they can easily lose track of time. For this reason, such types may experience themselves as undirected or indecisive.” (p.188)
“This self-experience derives, in part, from the immediacy of the type’s dominant function. Introverted Sensation motivates ISTJs to acquire facts and to retain them, but it offers no way to discriminate among them rationally. These types may need to deliberately quell their desire for more information in order to develop stronger Extraverted Thinking skills.” (p.188)
“Without sufficient contribution form their secondary function, ISTJs feel that they never have enough information to make a good decision. They may be particularly cautious about decision that will require a sustained emotional investment over time. Thus, they may settle for situations that strike them as practical or appropriate rather than exciting or desirable, or they’ll defer to someone whose knowledge or investment in a project is greater than their own.” (p.189)
“Beneath their apparent detachment, ISTJs can be badly hurt by criticism or rejection. They have a strong need to feel useful, appreciated, and valued. They may feel quite insulted when someone appears to question their word, their expertise, their experience, or their honor. Their vulnerability in this regard can be surprising, and it’s usually in evidence only when the situation is already out of hand. An ISTJ whose pride has been hurt will become distant rather than argue, and it may not be at all clear what the type experienced as the final straw.” (p.189)
“ISTJs take no pleasure in losing control and they don’t like to be caught off guard by what they feel. They want to be able to master a situation by way of knowledge and practical expertise. Indeed, most ISTJs are inclined to guard their emotions—save, perhaps, for righteous anger—believing that feelings are private and can be overwhelming to the senses. Accordingly, they will sometimes engage in overly correct behavior, drawing from traditional forms of etiquette to keep a potentially volatile situation stable.” (p.189)
“Male ISTJs, who constitute about three-quarters of this type, often relate to women, for example, with a kind of gallantry that can strike one as a little patronizing. The type’s propriety in this regard can sometimes result in an impression of quaint virtue, but it can also suggest something coarse and instinctive just beneath the surface, held relentlessly at bay.” (p.189)
“Indeed, ISTJ males are likely to be quite different in the company of men than they are with women, and they enjoy the opportunity to be “themselves” in an all-male situation. Other types can be surprised by this aspect of the ISTJ, because they’ve mistaken the type’s interest in concrete facts for cool cerebralism rather than the Sensate investment it is. ISTJs, both male and female, nearly always maintain an interest in outdoor activities pursued alone or with others—handball, hiking, hunting, fishing, weaponry, camping, scouting, and so forth.” (p.189)
“It should be noted that, demeanor notwithstanding, an ISTJ’s impressions of a conversational exchange can be unexpectedly and intensely personal. A discussion that takes place around a subject of mutual interest may strike the type as a form of intimate revelation—to the extent that he or she will feel self-conscious afterward, as though the relationship had become prematurely close.” (p.190)
“When this kind of exchange occurs between two ISTJs, they tend to alternate between enthusiams and caution, cataloging mutual knowledge and experience, but also recognizing that acquired facts may be related to deeply private needs and feelings. Indeed, such conversations should not be mistaken for a dry game of one upmanship. The way a person talks about a common interest will tell most Introverted Sensates exactly who that individual is and whether a friendship should be pursued further.” (p.190)
“Of course, this entire style of conversation is typically Introverted. ISTJs do need to develop their Extraversion as well, in order to recognize and adjust to limits and interests that don’t have anything to do with their inner selves. Some ISTJs develop their Judgment just far enough to discriminate among their many perceptual impressions, without learning how to relate them to the needs and expectations of others.” (p.190)
“Such types can be exasperatingly inflexible, because they turn to Introverted Feeling, their tertiary function, when they’re trying to stand firm. They become quite sure that their ideas about what is important and unconditional, and they use external rules to confirm and authorize their impressions. In control, an extreme ISTJ can come across as a martinet. As a subordinate, the type may be restricted and fearful of acting without permission.” (p.190)
“ISTJs locate their own authority when they recognize that their way of seeing the world is unique to themselves and requires constant relationship to others’ logical expectations. When these types accept their genuine individuality, they work hard to adapt their strengths and ideas to social reality as it exists, and they can sometimes move mountains.” (p.190)
“Such ISTJs have no need to prove themselves, and they don’t insist that others live life the way they do. They don’t have to. People see them as models of responsible, caring, civilized behavior, and seek them out as advisors, teachers, and leaders.” (p.190)
INFP
“INFPs are the type of whom people say, ‘Still waters run deep.’ Oriented by Introverted Feeling and extraverted Intuition, they’re both highly idealistic and quietly tolerant of others’ ideas” (396).
“Although Feeling always determines a form of idealism, the values determine by Introverted Feeling are different from the Extraverted sort. Extraverted Feeling presides over social values – current ideas about how relationships in the communities are best conducted. Introverted Feeling determines subjective values – convictions about how life is best lived” (397).
“Such values are trained by direct experience of good and bad behaviors, and they claim us from within. But relationship gradually teaches us that some of them transcend our individual circumstances, linking us irrevocably with other human beings” (397).
“Found in only 1 percent of the population, the INFP’s understanding of reality is quite nearly like the one described by mystics, who believe spiritual energy descends to earth by way of eternal ideals – structural patterns that bring order out of material chaos. By aligning their behaviors with these ideals, mystics can, presumably, bring life into harmony with its divine potential” (397).
“INFPs may not describe their approach in metaphysical terms, but it’s a rare INFP who doesn’t see in nature’s underlying pattern intimations of a larger purpose. Whether they write, teach, nurture, conduct research, make art, or devote their lives to spiritual service, their work becomes the agency through which they can grasp those ‘distant deeps and skies’ in which ‘fearful symmetries’ are framed” (397).
“INFPs yearn to experience oneness with their circumstances, but Intuition prevents them from satisfying this longing as ISFPs do, by losing themselves in a physical activity. Intuition doesn’t push INFPs to act. It pushes to interpret: to see the potential of their thoughts and behaviors in terms of their ideals” (397).
“Because their ideals are wholistic, INFPs feel responsible not only for their actions but for their desire to take action, and they have a nearly karmic idea of balance. If they betray their ideals in either deed or feeling, they try to make restitution. When good things happen, they may worry about paying a price” (397).
“It’s instructive to compare these types to ENFPs, who share the same two functions but understand life very differently. ENFPs rely on Intuition to gauge the nature of an external context and Feeling to recognize the values of the people in it. The best illustration of how this works is President Clinton’s unrivaled ability to identify with an audience and sympathize with their aspirations. ENFPs generally believe that people will recognize their good intentions, even if their behavior falls short of them” (397).
“INFPs approach reality from the other way around. Introverted Feeling prompts them to hold unconditional human values, and they use Intuition to figure out what that means in terms of their existential context. Asked whether he had ever had an extramarital affair, President Carter said no but allowed that he had experienced ‘lust in his heart.’ This is quintessential INFP perspective. Such types feel responsible for their hidden intentions, even if their behaviors exceed people’s expectations” (398).
“Given their focus on what it is to be human, INFPs are not always easy to recognize as types. Their outward behaviors vary widely. Some are reserved and prefer one-to-one conversations, but a surprising number of INFPs enjoy performing and may be singers, actors and comedians. In all cases, however, INFPs need a fair amount of time to themselves” (398).
“Although they identify strongly with expressions of joy, sorrow, pain, and vulnerability in others and respond compassionately to people who need them, they’re accessible only up to a point. Once that point is reached, they’ve genuinely depleted their social capital and need to recoup” (398).
“It’s easy to misunderstand INFPs in this regard, because they relate to others in the same low-key, easygoing way that characterizes ISFPs. They’re often wry, and if they’re comfortable, they’ll contribute a running pattern of perceptive remarks and observations. Thus, it surprises people when the INFP abruptly winds down and wants to be alone” (398).
“Moreover, these types are sympathetic listeners, genuinely interested in what others do and believe, which encourages people to anticipate a more extensive relationship than the INFP may have bargained for. Until they recognize what’s happening, INFPs may be constantly obliged to extricate themselves from situations they got into simply by virtue of warmth and goodwill” (398).
“Along the same lines, these types have high romantic ideals, and express this aspect of their personality somewhat tentatively. This can lead people to believe they’re shy or not interested in physical intimacy. In actuality, INFPs long for communication of mind, body, and spirit, and they envision a partner who can appreciate the nature of their inner world and give them access to it in sexual terms” (398).
“However, like all P types, they don’t want to set goals for their relationships; they want good things to happen naturally, to grow out of the situation as it exists. Moreover, their finely tuned Intuitive skills lead them to believe that the right person would see through all the surface nonsense to the inchoate potential within, read it in their body language, their musical tastes, the images that move them, the underlying meaning of their words” (399).
“This ideal picture is also a consequence of their wholistic point of view. INFPs have a hard time articulating who they are inside, and they keep hoping the objective situation will give them enough reference points to express themselves in a way that feels true and right. Indeed, INFPs can have a hard time figuring out what they’re called to do in life” (399).
“Unlike Extraverts, whose primary self-image is tied up with their outward behaviors, INFPs may get at their self-experience only when it conflicts with their external choices. Even those INFPs who have plugged themselves into a career that allows them to do something meaningful and good may not feel sure they’re doing enough. They’re nagged by an impression that something else is supposed to happen, something that will tell them what they’re really meant to do” (399).
“Al Capp used to draw a syndicated cartoon called Long Sam, in which a grizzled, pipe-smoking mountain woman dispensed hard-won wisdom about life. When it came to human values, however, all she could say was, ‘Being nice is better – because it’s nicer.’ INFPs can find themselves in the position of saying something very much like that when they try to articulate what they believe and why. Their values have no predictable reference points in law and social convention. They cut through all that to the heart of the matter” (399).
“In order to actualize their certainties and ideals, INFPs generally find a place for themselves in the prevailing social system that allows them to focus on human potential. But given the fact that their values are more fundamental than institutional priorities, they’re constantly frustrated with the time and energy they spend on structural maintenance – society’s ‘edifice complex’” (399).
“So they’re in a quandary. Because, apart from jobs of this sort, they don’t have a clear idea of what it would mean to act on their values. The right-brain character of their Feeling goals suggest a life spent in pilgrimage, free from objective attachments – even a sense of home” (399).
“And some INFPs do, in fact, give their lives to missionary work or the priesthood or a spiritual community. But most INFPs, by the time they’re wrestling with this question, have established a home and family and/or a place for themselves in the community, and they’re not inclined to hurt the people they love for the sake of an ideal they can’t quite define” (400).
“So frustration gradually pushes INFPs into using their Intuition defensively, to protect what feels like their “true” self against the imperfect outer situation they’re living in. They feel guilty about this, too, because they think they ought to be satisfied with what is, after all, a perfectly decent life course” (400).
“INFPs who are relying on their Intuition this way usually take one of two directions. Either they become permanent seekers – good at many things but disinclined to stick with any for long – or they become somewhat passive, unable to articulate what they want but dissatisfied with what they they’re doing” (400).
“These latter types generally feel that they don’t have enough initiative, but they don’t get much accomplished apart from others’ routines and structural expectations. Left to their own devices, they tend to procrastinate or do unnecessary tasks to avoid more important ones” (400).
“When INFPs spend most of their energy protecting their inner realm from attachment to an imperfect outer situation, their least-developed functions, Extraverted Thinking, doesn’t get very conscious. Such types are often excellent at managing time and resources for others but have a harder time structuring and organizing their own lives. In fact, they may become romantically involved with a strong J type, who can anchor them to the objective world, but can’t provide what they actually crave: something to pull them to the surface of their own personality” (400).
“INFPs need to use their Intuition in a genuinely Extraverted way. They’re accustomed to using Intuition to figure out how to deal with an existing context; they need to apply it, instead, to the task of defining what an objectively good situation would be like” (400).
“This is by no means easy for INFPs to do. When they stop using Intuition to defend themselves, their first instinct is to assert the importance of their Feeling goals. They challenge people, question the aspects of the situation that strike them as problematic. This “feels” like Extraverted behavior, but it isn’t. Extraversion moves us to take the objective world for granted. It’s Introversion that strives to adapt the objective situation to itself” (400).
“Meanwhile, the Extraversion these types actually require goes underground. Extraverted Thinking becomes so profoundly unconscious that it floods them with impulses directly opposed to their Feeling aims” (401).
“Like all types, INFPs don’t recognize this internal pressure as an opportunity to grow. They feel the influence of their Thinking function, but they mistake it for an outward problem. They feel increasingly thwarted and boxed in, false to their real selves, and they’re sure the reason is their accommodating spirit. Thus, they go back to using Extraverted Intuition as a defense, but more aggressively, because the stakes are higher. They decide to fight some of the things that are hemming them in” (401).
“INFPs don’t like conflict, so their rebellion is often subtle and passive-aggressive in form. They drag their feet when someone pushes them to do something they don’t want to do, sometimes until the person gives up, or they “yes” people, then do as they like. None of this helps INFPs to find their own truth; it actually takes them away from the quest, concentrating their attention on all the wrong things” (401).
“One might consider, in this respect, the characters in the movie The Big Chill – friends from the sixties who come together, twenty years later, for the funeral of their compatriot, Harold. Harold had been a role model for them, a free spirit guided entirely by Introverted Feeling ideals. His suicide makes them realize how far afield subsequent choices have taken them from the values he inspired” (401).
“Thus, they each attempt to prove that they’re not locked into the social roles that appear to define them: the unmarried lawyer decides to get pregnant; the upscale franchise king gives his friends illegal stock information; the society matron has an extramarital affair” (401).
“INFPs under the influence of Extraverted Thinking are not unlike these characters. They’re self-conscious rather than idealistic. Their actions aren’t being guided by an inner code, leading them to positive action, but by a need to defend themselves against others’ priorities” (401).
“In fact, such types usually find that ignoring others’ expectations doesn’t give them enough protection, and they turn to Introverted Sensation, their tertiary function, to keep their Feeling values intact. They literally avoid situations that don’t accord with their primary self-experience, forfeiting relationships rather than experience inner conflict” (401).
“Ironically, the more unconscious Extraverted Thinking becomes, the more INFPs call attention to themselves in their attempt to keep their environment congenial to their values. Their objective preferences become idiosyncratic, forcing others into unusual accommodations in order to relate to them. Given the fact that they’ve projected their STJ impulses on to the impersonal structure of society, they feel morally vindicated. What can they do to change a whole system? What’s important is to be true to themselves; others have to take responsibility for their own choices” (402).
“It should be emphasized that INFPs aren’t wrong about this. They do need to be “true to themselves.” However, Introverted Sensation doesn’t help them do this. It keeps them locked into things as they are. It turns their ideals into an external value system that defines some situations as congenial to their needs and others not, leaving them no choice but to stay out of the ones that aren’t” (402).
“When INFPs develop sufficient Intuition, they stop focusing on things as they are and begin to see new possibilities for action. One might consider, again, the characters in The Big Chill. Among the mourners at the funeral is a young woman who was living with Harold when he committed suicide. She strikes the old friends as shallow, a silly adolescent, unable to appreciate who Harold really was” (402).
“When INFPs first make contact with the Extraverted character of their Intuition, they see it in the same terms – as a shallow approach to life, without meaning. It invites them to give up their expectations, live in perceptual harmony with anything that happens. This strikes them as irresponsible. As the song says, “If you don’t stand for something, you’ll fall for anything” (402).
“The more they wrestle with this perspective, however, the more they see that their values have nothing to do with their comfort or discomfort in any situation. They constitute a way of seeing life, a way of relating to any situation. When INFPs use their Intuition to figure out how to make this relationship manifest, they see that they have many options to take positive action” (403).
“It may be noted that at the end of The Big Chill, one of the friends, the one who had been resisting a social definition, decides to help the young girl finish a house Harold has been building in the wilderness. This is the sort of thing that happens to INFPs who wake up to the wholistic nature of their inner life. They realize that being responsible to their values isn’t about fighting what exists; it’s about building, recognizing that they can do things, want to do things that might not even occur to others” (403).
“INFPs who reach this point don’t ignore the problems of society or betray commitments they’ve already made. They simply play from their strengths. For example, an INFP social worker of my acquaintance, after much reflection, left his position to design a unique company of his own, which helps corporations restructure their organizations in terms of human values. He no longer feels quite at home in the world, but he’s at peace with himself, working on things that truly drive him” (403).
“Sometimes INFPs simply need to make room in their lives to give their strengths a chance to grow. For example, they may take up creative pursuits – writing, composition, design art: something that allows them to give their ideals material form. Sometimes they volunteer their services to take care of homeless animals” (403).
“In general, however, well-developed INFPs live lives that don’t look much different from anyone else’s. What’s different is their perspective. They strike others as unassuming, even deferential, because they treat people with unconditional love and compassion. In consequence, their actions, their choices, their way of life can awaken others to human values the community has not acknowledged” (403).
“For example, a small Midwestern church has hired a pastor from the New York area, and there were many discussions on the church board about the difficult transition for the congregation. An INFP board member saw the situation from the other way around, empathizing with the minister and his family, uprooted from their home and friends in the East to make a new life for them” (403).
“When the family arrived, a day ahead of the moving truck, picturing themselves eating pizza on a bare floor, they walked into the parsonage and found a table set with flowers and good china, a refrigerator full of dinners and staples, and soap and towels in the bathrooms. Such actions see through external distinctions of role, background, and status to focus on our common human links” (404).
“INFPs sometimes underestimate their strengths because there are so many problems in the world that can’t be solved by changing people’s hearts. But they shouldn’t. The effects of their decisions are often incalculable, renewing people’s faith in human nature.” (404).
ISFP
“Literature that advises us to found our inner child probably has in mind the fresh, uncomplicated vision that ISFPs bring to their world. Oriented by Introverted Feeling and Extraverted Sensation these types are very much in the here and now. Naturally spontaneous, they live as though each experience were newly discovered and their primary purpose were to be in harmony with it” (391).
“Such types understand outward reality by way of sensory skills so finely tuned that they’re likely to have a strong identification with nature. One might picture all those deceptively easygoing film heroes who make their statement by breaking into the psych lab and uncaging the chimps or by driving the horses out of the corral and watching them thunder back into the wild. Almost all ISFPs have a special gift for communicating with children and animals and they may have a green thumb as well” (392).
“The unconditional nature of this respect may be illustrated by an ISFP of my acquaintance who ‘adopted’ a computer-generated puppy. When a friend asked her to squirt the creature with virtual water from a spray bottle that came with the program, she was horrified. ‘How can I do that?’ she asked. ‘It’s playing so happily!’ (392).
“Whenever this sensitivity comes into play in the social arena, ISFPs have a sense of mission. They may, for example opt for a pacifist, vegetarian, or anticruelty lifestyle, or volunteer their services to movements like Greenpeace and Amnesty International” (392).
“Like other types who use Sensation to deal with the outer world, ISFPs learn by experience, and they need hands-on contact in order to know something well. Unlike Extraverted Sensates, however, they don’t require perceptual novelty to stay interested in something. While their Judgment is engaged, ISFPs are focused, contained, and nearly inexhaustible. Whether they’re athletes, artists, paramedics, or nurses, whether they make music or take care of stray animals, these types are likely to regard their work as a vocation rather than a profession” (392).
“Indeed, their engagement has nothing in common with the goal-oriented Judgment of ESJs. ISFPs don’t think in terms of objective limits and requirements. They think in terms of values—what’s right in the situation at hand. They lose sight of themselves as objects, rushing in where angels feat o tread” (392).
“I knew an ISFP who worked in community program locating resources for people who ordinarily lived in boxes and tunnels and under bridges. After work, he’d go out on his own trying to find program dropouts in an effort to persuade them to return. He’d often end up in dangerous situations, but it never made him more cautious. The vulnerability of those people struck him as more important than his emotional and physical security” (393).
“ISFPs are often like this in an activity that truly captures them. They’re not attempting to ‘go the extra mile.’ It’s who they are. In fact, their lack of objective boundaries usually keeps them from freelancing their skills the way their ISTP kindred do” (393).
“ISFP artist, for example, tend to seek ongoing support for their activities—in the way of grants, contribution, seed money, opportunities for performance, and so forth. These types don’t want to think too much about the objective conditions of their employment. They want space that allows them to do what they feel called to do” (393).
“It may be noted, in this respect, that as Fox Mulder, of The X-Files, has gradually metamorphosed (with the show’s success) from a rumpled INTJ obsessive into a peripatetic ISP folk hero, he spends nearly all his time outdoors, investing himself in cases as they come to hand, happy to avoid the confines of the institution that provides his objective means. Moreover, his partner, the hyperrational Scully, now serves him less as an analytical counterpart than as a frustrated protector, advising him of his bureaucratic options” (393).
“ISFPs tend to attract Extraverted Thinkers of this sort, whose anchorage in the world of established systems keeps the type aware of objective responsibilities. ISFPs don’t seek this kind of relationship so much as let it happen to them, granting another’s investment in material stability and welcoming the structural touchstones, without according them much larger importance” (393).
“Although ISFPs are warm, generous, and develop deep connections to people, they have a certain resistance to attachment for its own sake. One might consider Zoe, the twenty-something daughter on the comedy Cybill. Zoe is portrayed as an ISFP musical prodigy, romantically drawn to a young man much like herself. Recognizing the worth of the relationship, the two have agreed to keep the connection platonic, lest the social repercussions of sexual involvement rob them of immediacy and the natural rhythms of life as it happens” (393).
“All ISFPs aren’t like this, of course, but the image catches the flavor of the type’s caution with respect to ownership and material possession. Where ISTPs regard a tool, brush, or instrument as an extension of their body, ISFPs are like those rock musicians who break their instruments at the end of a performance. They want to see through the objects that serve their talents and ambitions, lose themselves in the creative act itself” (394).
“ISFPs will even take up disciplines designed to free them from material dependence, but this is a bit like taking coals to Newcastle. They’re more likely to abdicate responsibility for their objective situations than they are to be trapped by what they own” (394).
“In fact, ISFPs are more likely to feel bogged down by possessions and material constraint when they’re too dependent on their dominant function. Their inferior function, Extraverted Thinking, is too far away from their conscious aims and goals. Whenever they encounter a situation that can’t be addressed with their dominant skills, Extraverted Thinking exerts a strong unconscious influence on them, and they lose touch with their accustomed sense of values” (394).
“This is the normal course for affairs when a primary function is too strong. The psyche pulls us away from our usual behaviors, giving us time to develop more of our potential. Like other types, however, ISFPs don’t recognize their Thinking impulses as part of themselves. They simply feel that they’re losing contact with their deepest self, and the only way the know how to solve the problem is to reject the claims of anything that doesn’t support that contact” (394).
“For example, ISFPs who join a spiritual organization to nurture a contemplative life can be shocked to discover that structural containment has no organic relationship to their aspirations. Their values are being standardized and directed rather than nourished. Once these types define the problem this way, however, they don’t know what to do. The right-brain character of their Feeling goals suggests a life lived in surrender to their craft or commitment, but they aren’t sure how to make that happen on their own” (394).
“So frustration gradually pushes ISFPs into using their secondary function defensively, to assert their existential freedom. Their devotion to a vocation becomes paralleled by an equally strong need to prove their objective self isn’t important. This need doesn’t necessarily result in a crash-and-burn lifestyle, although it can. Such types may simply do whatever it takes to stay aware of the creative force within—without much thought for the logical consequences. The image these ISFPs construct has quite a bit of resonance in the Sensate pop ethos, and such types can acquire what may be called a tragic sense of cool” (395).
“It’s ironic, therefore, that what they actually need is more contact with their Extraverted Sensate side—not to defend themselves against their inferior aims, but to balance their primary needs against their real circumstances. When ISFPs don’t get enough Sensate development, they end up using Introverted Intuition, their tertiary function, to kept their dominant self-image intact” (395).
“Under most circumstances, Introverted Intuition keeps ISFPs well-rounded. It helps them to recognize that their way of seeing reality is important and real—even when they can’t find a way to express it. Used as a defense against Thinking impulses, however, Introverted Intuition simply increases the ISFP’s resistance to others’ influence on them” (395).
“In one of the X-files episodes, for example, Scully asks Mulder, ‘Have you ever thought about dying?’ ‘Yeah,’ he says, ‘once when I was at the Ice Capades.’ ISFPs who are trying to resist others’ claims on them are almost always defensive in this flip way, believing that others will merely appropriate their deepest feeling for their own purposes” (395).
“Such types can end up feeling like Kevin McCarthy in Invasion of the Body Snatchers, faced with two bad choices: they can go to sleep, let the pods take over, and wake up happy to be programmed, or they can fight to stay awake and spend the rest of their lives resisting cooptation” (395).
“When ISFPs develop sufficient Extraverted Sensation, it takes them outside the terms of this either-or dilemma. They begin to see that their inner potential dictates outward responsibilities. An image given to me by Dr. Ann Ulanov, a Jungian analyst, addresses this situation in an interesting way” (395).
“She said that if you live in close contact with your inner world, it’s a lot like living by the sea. You can get flooded unless you can build a structure that suits your needs. Your first instinct, however, is to build the kind of house the towns people live in, because that’s the kind of shelter others will help you construct. This is precisely the kind of house that will be ruined when the tide rises. For a while you think, ‘I should have built a better townhouse.’ But gradually you reject others’ advice and you live without structure’ (396).
“Why not build the kind of house that will serve your actual needs? Build the kind of house the fishermen build, one the water can go through without knocking it down. And when visitors show up, warn them not to wear their good shoes, because their feet may get damp during dinner” (396).
“This is really the primary task for ISFPs: to recognize their need, as it were, to live by the sea of their inner world. Their secondary function helps them to construct a life for themselves that honors their genuine gifts and calling. It doesn’t impel them to reject everything they already have and know. It moves them to recognize their purpose for being alive and to find their own path” (396).
“Well-developed ISFPs live, as it were, between the sea and the town, doing what they need to do. In consequences, their creations, their choices, their way of being can remind people of important things the community has forgotten” (396).
INTP
Like ISTPs, INTPs depend on Introverted Thinking, a form of reasoning that operates on the basis of immediate perceptual information. They, too, are able to grasp, all at once, the structural logic of a system or process. ISTPs, however, relate to the outer world with Extraverted Sensation, so the perceptual nature of their reasoning is apparent. They obviously need visual and tactile contact with a process in order to understand it. INTPs relate to the outer world with Extraverted Intuition, so their need for direct experience is not as clear.
Such types are interested in the logical possibilities of structure: the way form and context interact and exert change on each other. Thus, they’re more at home than ISTPs with theoretical reasoning. INTPs do, however, require visual and tactile contact with a system in order to reason properly. Their primary method of exploring structural possibility is almost always a form of design or model making. Such types compose music, render blueprints, perform lab tests, work up magazine layouts, draft construction schemes, and so forth.
Because their focus of attention is on possibility, INTPs are likely to be more interested in the idea that animates a system and its impact on reality than they are with the system’s objective utility. In fact, there’s an old joke, intended to implicate economic theorists, that offers a bit of insight into the type’s approach.
A chemist, a physicist, and an economist are stranded together on a desert island with only a crate of canned tuna to keep them alive. The problem is how to get the cans open. The chemist suggests putting them in the ocean for a while, until the salt compromises the tin. The physicist says, “No, let’s point the cans in the sun until they explode.” They both turn to the economist, who says thoughtfully, “Let’s assume we have a can opener.”
Galvanized by Intuition, INTPs will strive for theoretical systems that include all possible variables, but such theories can fall short of application in the real world. Accordingly, these types can be frustrated by the need to defend their ideas in terms of Extraverted logic, which begins and ends with material application. Even when they develop high-level communication skills, INTPs aren’t really talking about the same things that concern left-brain Thinking types. Or they’re talking about them in a way that leaves too much room for speculation to suit an Extraverted analytical mind.
The biologist Rupert Sheldrake, for example, developed a revolutionary theory about recurring patterns in nature, which derived, he says, from an attempt on his part to picture God less as an embodiment of unchanging law than as an evolving organic process. This is the sort of metaphor an INTP might use to make clear that the underlying idea informing a project, but it has no means of evaluation in left-brain Thinking terms.
On the other hand, because INTPs see logical implications in terms of systemic change over time, they are often well ahead of the curve on issues of cultural evolution. They seem like ENTPs in this respect, but the two are actually mirror images.
Like all Extraverts, ENTPs take the outer world for granted. They use Extraverted Intuition to gauge a situation’s possibilities, then strategize with Introverted Thinking to bring them about. For example, the man who developed the Wal-Mart conglomerate might well have been an ENTP. He Intuited the venture’s commercial potential, then worked out the structural design for making it happen.
INTPs approach reality from the other way around. They use Introverted Thinking first, to get a sense of a situation’s structural pattern, then use Extraverted Intuition to recognize its impact on what actually exists. The architect Frank Lloyd Wright, for example, recognized how prefabrication could lead to superhighways, suburbs, and shopping malls long before Wal-Mart has even a gleam in an entrepreneur’s eye.
Clearly, most people recognize that color, space, light, and order have a great deal to do with their experience of a restaurant or a housing project or a government building, but most of us are not thinking about the internal logic of our technical creations. An INTP designer, however, might spend a lifetime exploring Western culture’s attachments to angled frames as opposed to ovals.
Because INTPs represent only 1 percent of the population, they’re not well understood, and their interests may be just rarefied enough to make them feel isolated. This sense of isolation is compounded by the Introverted nature of their thought process. All Intorverted P types run the risk of losing contact with objective reality apart from the areas of knowledge and experience that suit them.
Unlike the ISTPs, feelings are not usually visible in the type’s demeanor. In fact, these types may find it difficult to know what they’re feeling until they experience themselves as out of control. Their ability to sort out their emotions and recognize their meaning is not well developed.
For this reason, romantic attachment can pose a problem for INTPs. They usually develop enough Extraverted Sensation to engage in experiences that draw on their primary skills, but they don’t fully appreciate the objective image they display to others. And because Extraverted Feeling is their least-developed function, INTPs can be shy and awkward about affectional connections. At midlife, they may abruptly realize they haven’t given enough thought to issues of marriage, children, or domestic stability. They may not even be certain about what they require from a partner. Their sense of predictability involves matters of impersonal design; the personal realm strikes them as utterly without rational order.
Thus, such types tend to marry other INTP colleagues or find themselves blindsided by attraction to people who can make up their deficit in Extraverted Feeling. These latter attractions are not easy to sustain in the long run. INTPs require a great deal of time to be alone with their thoughts. They’re also likely to overlook, or disregard as unnecessary, the ritual signs of affection that Extraverted Feeling types depend on for a sense of well-being.
Most INTPs need more contact with the Extraverted nature of their secondary function. They’re accustomed to using their Intuition only to assess logical probability in a system. They have to make a deliberate effort to apply it to themselves – to see the effects they have on others in the larger picture, or to entertain possibilities outside their familiar framework of expectations.
Without the Extraverted ability, INTPs can get locked into their dominant function, and their least-conscious function, Extraverted Feeling, gets too far away from their will and aims. Such types are gradually flooded with unconscious desires for others’ approval and appreciation, which undermine their impersonal approach to life.
This internal drama is a healthy one. INTPs that are pushed away from their usual frame of mind can get some perspective on their accustomed behaviors. Like all types, however, they don’t experience unconscious pressure as a part of themselves. They experience as something that’s happening to them – a problem with their situation, caused by other people. They may believe, for example, that they aren’t getting the appreciation they deserve.
In response, INTPs sometimes seek reassurance – by turning to Extraverted Sensation and attempting to cultivate a better image. They’re more likely, however to reassert their familiar Thinking oriented sense of self, concluding that they’ve become too dependent on others’ views. They worry that their eneds are right on the surface, so they attempt to increase their self-sufficiency. As a result, they become more self-oriented, disinclined to accommodate others, or to do anything they don’t want to do.
The more emotionally unavailable these types become, the more they experiences themselves as emotionally vulnerable, constantly open to heartache and rejection. They begin to isolate themselves from others, persuading themselves that most people are too pedestrian to grasp what they can see. This is the point at which INTPs tend to lose touch with their secondary function altogether and turn, instead, to their tertiary function, Introverted Sensation.
Well developed, Introverted Sensation helps us to recognize information that has consistent meaning for us, apart from prevailing social assumptions. Such information is crucial for ESJs. Extraverted Judgers are likely to ignore their own priorities for the sake of a job or a social role.
INTPs, however, whose Judgement is Introverted, don’t need more reasons to ignore social expectations for the sake of inner needs. Introverted Sensation makes such types highly critical of others’ expectations. Their Thinking becomes complicated speculative, less and less related to reality as it actually exists.
Introverted Sensation also focuses the type’s defenses on issues of material well-being. Such INTPs worry about the effects of others on their health, or about the harmful aspects of food or the environment, and they circle the wagons accordingly. Sometimes they strike others as hypochondriacs, but their physical states often mirror the emotional states they aren’t recognizing in themselves.
INTPs of this sort are attempting to limit their perceptual intake to the familiar, but the result is the increasing influence of Extraverted Feeling. As Extraverted Feeling gets less conscious and more powerful, it begins to actively oppose the INTP’s dominant approach. INTPs in this position are likely to draw attention to themselves. They’re hyperaware of people’s reactions to them, and they respond with vehemence. Extreme INTPs are frequently embroiled in disputes with people, and they spend a great deal of time and energy defending their thoughts in journals or on the op-ed pages of local newspapers.
INTPs who make a deliberate attempt to apply Extraverted Intuition to themselves feel an immediate sense of conflict. Like Extraverted Thinkers, these types confuse their ability to be impersonal with the ability to be objective, and Intuition is usually their first recognition that objectivity has nothing to do with removing oneself from the situation. It offers them an image of themselves as apart of the larger picture, with effects on others that can’t be entirely calculated and a dependence on others that is not entirely under their control. INTPs ultimately get in touch with their Feeling function this way – through their Intuitive objectivity.
The late Corita Kent, an American artist noted for her silk-screen prints, offers a nice illustration of this perspective in her description of her work:
A painting [is] a symbol for the universe. Inside it, each piece relates to the other. Each piece is…answerable to the rest of the little world. So, probably in the total universe, there is that kind of total harmony, but we get only little tastes of it….That’s why people listen to music or look at paintings. To get in touch with the wholeness.
INTPs who come to terms with relationship by way of Intuition recognize their responsibility to others in the way Kent describes. They feel answerable to the people who share their situation. Such types have a strong sense of purpose, but they don’t feel the need to calculate their behaviors in terms of logical probability alone. They recognize the existence of the unpredictable and the improbable: those aspects of life that require a leap of faith, or the ability to trust someone besides themselves.
ISTP
ISTPs relate to the world by way of Ti, a form of logic that's tied to their direct perceptual experience. It works in the background of awareness, guiding their actions, facilitated by visual and tactile cues in an unfolding situation.
Because Ti works like this, as a means of negotiating immediate experience, ISTPs have to be active in order to use it. They need hands-on involvement so they can feel a situation's impact and gauge the effects of their behaviors on it.
Unless they experience this kind of contact, they're likely to be bored and restless. They can't get enough perceptual feedback to sustain their attention. Even their language may reflect their hands-on preference--in phrases such as, "I get it," "Can you handle that?" "Stop pushing me around," "That is really hot!" "Cool!" and so forth.
For this reason, ISTPs can be misunderstood as impulsive or hyperactive. They don't reason conceptually, like Te users. They reason with their bodies as a situation is happening. For J types, who see the world in terms of general rules and predictable structural relationships, ISTPs appear to be out of control, unable to delay gratification, insistent on doing whatever they want.
But Thinking is always discriminating and logical, whether it's Extraverted or Introverted. Te is objective. It operates by way of signs that represent what is generally true about experience. Ti is subjective. It operates by way of participation and a grasp of what's structurally possible in an immediate situation.
The difference is very clear when it comes to styles of learning. For example, the classic approach to learning to play the piano is a Te one. We start with the objective tasks of reading music and practicing the scales. ISTPs don't learn this way. Indeed, these types may have a difficult time understanding the point of conceptual systems. They usually learn to play by ear, because they need to recognize the underlying structure of music, the way it takes shape as an unfolding pattern.
This kind of perceptual learning ultimately trains the ability to improvise. Once ISTP musicians grasp the internal structure of a song, they're free to experiment with its possibilities, depending on their mood, their audience, and their immediate context. Such improvisation is far from doing "whatever they want." Their skill is to find a reasoned balance between structure and freedom.
ISTPs live for that kind of balance--in everything they do. It makes every situation one of a kind. Indeed, it was probably an ISTP who invented the phrase "You hadda be there." The point of life for ISTPs is to be fully present to it, so that their direction becomes clear in the process of living it.
One can see this perspective very clearly in the tendency of such types to freelance their services. These are not the sorts who opt for a fast track to a career and the American dream. They prefer to remain independent, to get paid for their time and skills, and not for their loyalty to a particular institution.
ISTPs may be photographers or painters, mechanics, welders, construction workers, visual effects mavens, chefs, surgeons, musicians, and so forth, but the jobs they do always involve hands-on involvement and the opportunity to improvise. ISTP arc welders are constantly anticipating the results of their actions and adjusting the intensity and angle of the current accordingly. ISTP film actors immerse themselves in a role, harmonizing themselves with their character's internal structural pattern, allowing it to take them into areas of psychological risk.
ISTPs tend to "freelance" their relationships as well. Part of the pleasure of being with friends is that structure is an immediate phenomenon. It doesn't exist before the situation unfolds, so the element of surprise is always a factor. When too many expectations dictate an ISTP's behavior, the type may be disruptive, attempting to get in touch with the real world of immediate data. In this regard, ISTPs resemble ESTPs.
This resemblance is only superficial, however. Average ESPs are somewhat indiscriminate. They depend on their past experience to understand reality, but they need novelty to stay interested, so they're excited by new situations that require familiar skills.
ISTPs are not like this. ISTPs are utterly present oriented, so they don't require novel perceptual experiences to stay interested. Once they're using familiar skills, every situation is new. Such types may leave school for lack of Extraverted discipline but spend hours every day perfecting the same Introverted Judging skills--in a sport, the martial arts, the playing of an instrument, technological construction or repair--and every day the experience is completely different for them.
Moreover, ISTPs are not indiscriminate. ESPs try to enjoy whatever is happening. If they don't want to be in a situation, they'll "play along" until they can find a way to escape. If they can't escape, they'll create a humorous diversion to keep things alive.
ISTPs are either "with" a situation or they're not. If they're not, they will make no effort to pretend they are. They won't exhibit initial interest, explain, or apologize for their inattention or lack of compliance. When these types are disruptive, they aren't being playful. They feel trapped, isolated from the information they need to feel alive and aware.
ISTPs may do something they don't want to do for someone they respect, but they will not fake goodwill in the process. The commitments these types make are based on shared experience, not shared thoughts or feelings, and they have no reason to trust people who haven't proved themselves in areas they consider important.
The image created by this kind of behavior has a certain resonance in the Se pop ethos, manifested by the many film heroes whose perceptual logic, sensory skills, and laconic unpredictability manage to extract civilization from the jaws of corporate hypocrisy and greed. In real life, however, ISTPs may narrow their world to the extent that they have no idea what's going on outside their own environment.
Many ISTPs find a niche where their reliance on direct experience is necessary and rewarded. For example, such types can be excellent tacticians and, given the interest, have the potential to lead and inspire others. They know what individuals are likely to contribute to a team, and they have a "feel" for the synergy of a group in action.
This skill is evident whether they're coaching a sport, rehearsing a band, or working out a military strategy. Because they work with a situation's logical implications and not in terms of principles or hierarchy, they have an egalitarian attitude and can usually manage others without making them feel like subordinates.
Such types have also benefited from the advent of computers and interactive video games, which has shifted some of the emphasis in a school curriculum to individual sensory skills. The visual effects crews on films always seem to be composed of these types, who enjoy exercising their skills in the creation of realistic explosions, disasters, outer space scenarios, monsters, and computer-generated stunts for movies.
It should be granted, however, that ISTPs are still the most likely of the types to drop out of school or to graduate without acquiring much in the way of Extraverted reasoning skills. Ironically, given the highly Se-like nature of society, these types actually need more contact with the Se world than they usually get.
As state earlier, ITPs are not generally interested in novelty. They're interested in hands-on activity, and the Se world provides a great deal of opportunity to satisfy this interest. ISTPs may race cars, pilot small planes, snowmobile, play sports, or join a band to get the kind of action they need, and they're often credited with being in tough with their feelings because these pursuits so completely and passionately absorb them.
In general, however, these types experience their feelings only in the course of using their subjective logic. Their ability to sort them out and recognize their meaning is not usually well developed. Somewhat like ISTJs, ISTPs tend to acquire things that will give form to their inner lives. They establish collections and tend to display them in a somewhat ritualized way. The structural and aesthetic integrity of the arrangement may be highly important to them.
For example, many rock performers acquire extensive collections of guitars, which no one is permitted to touch. The many stores that have arisen devoted to comic book and trading card collectors may appeal to ISPs in general.
However, this Introverted manner of expressing their inner life doesn't give ISTPs any experience with the social vocabulary that tells people they're cared about and mean something to them. An ISTP's Fe function tends to be undeveloped to the point of being unconscious.
Verbal assurances mean very little to them, and they don't tend to offer them. If someone asks too much of them, they will simply walk away and seek the company of like minded companions. These types are not motivated to be unfaithful, but they're liable to lose interest when a partner changes direction in life or the connection seems to have run its course.
Extreme ISTPs, who rely exclusively on Ti, may attempt to avoid any situation that will require them to do something that doesn't come naturally to them. And they may be quite angry about the ways in which others are trying to control them and make them fit into a particular social niche. They may believe that people who have not had their background and experience have no right to judge them or expect anything from them.
These types need to get in touch with the Extraverted nature of their Se function. They need to make an actual effort to adapt to contexts they can't negotiate in their usual way. Extreme ISTPs think this will compromise their freedom or force them into a social straitjacket, but they're wrong about this. Such types need to get enough experience to keep their perceptual logic sharp. If they don't, they aren't taking in enough information, and they begin to feel alienated.
When ISTPs have developed Se well enough to recognize the validity of experiences unlike their own, they are likely to use their teriary function, Ni, to great advantage. It prompts them to improvise in a way that is highly original and makes a contribution to their field.
However, when they use Ni defensively, to keep their dominant function intact, these types identify very strongly with ideas that call the present structures of society into question. They attract to themselves not only the disenfranchised and the iconoclast but the psychotic and the troubled, without being able to offer anything beyond the common experience of feeling disrespected.
In general, these types are pushed by life to recognize that some experiences are the same for everyone, regardless of what they know or have to do. Human need and aspiration aren't variables that can be ignored; they're part of a situation's structural pattern, and logic itself dictates an alignment with them.
ITPs who learn how to do this realize a great deal of personal power. They don't withdraw from expectations that strike them as alien; they align themselves with the common human experience in a situation and improvise in the best sense of the word.
