Fi is a strikingly influential factor in the mindset of an ILI. ILIs tend to deeply value feelings of attachment to those whom engage them in a deep and lasting emotional kinship. They have a hard time establishing these sentiments as they are naturally disinterested in most people, who seem outwardly unremarkable or having nothing in common with them. However, when the ILI has developed deep interpersonal bonds, they tend to hold on to such attachments very deeply. ILIs are almost always deeply unconfident about their social abilities and, consequently, they rarely speak of their inner bonds with others to common outsiders with whom they share merely superficial acquaintanceships. Feelings of this sort are rarely talked about with others, but the ILI may be painfully aware of these sentiments for fear of appearing overly sentimental or having feelings that are "out of line" or inappropriate to their present level of social interaction. ILIs may tend to love from afar and in their solitude if there is something or someone they love, because of their lack of confidence in their own feelings. Some ILIs may even be closet romantics. ILIs can also be quite sensitive, despite their outward emotional reservation, and are sometimes far more emotionally vulnerable than they demonstrate.
In general, ILIs are fundamentally good-natured and conscionable people who may place a great deal of importance on ethical principles. In fact, ILIs may have a very strong sense of good will and loyalty towards others if they find the others to be similarly reasonable, trustworthy individuals. ILIs do not always demonstrate this loyalty explicitly. As a consequence, ILIs are not always seen as kind people, instead more typically appearing standoffish, cold, or hostile. If ILIs are drawn in by sincere and engaging individuals, the ILI's sense of compassion may be realized and so surface. ILIs can be calm, attentive, and sympathetic listeners to the plights of their emotionally volatile duals, and can be very drawn to the state of deep bonds that they feel with them.
Many less actualized ILIs hold a far more vindictive attitude. This occurs, among other scenarios, when ILIs are depressed about people, and especially when ILIs are suffering from a lack of support from others. In these scenarios the ILI may aggressively attack people's intelligence, ideas, or character rather unrelentlessly. Even so, such actions may precipitate conflict which the ILI is liable to find highly tiresome and frustrating -- as well as blurring the ILI's mental image of the facts, thus making him feel as though his work is unfinished. Such people who have been blacklisted are often in the ILI's eyes very deserving of this role, but the ILI may find that other people do not agree and faces the choice of either withdrawing in order to avoid interacting with the object of derision, or else continuing to interact, thus perpetuating the process and compounding the ILI's frustration. Such judgments may be very difficult to extricate from the ILI; such a process requires a copious amount of often thankless moral support and truth; SEEs are the only persons equipped for this task, and may in their occasional naivete of others' motivations benefit from the ILI's rather harsh stances. Typically, however, if the ILI is engaged with people with whom he feels very close and respects, he sees little need to interact with such individuals that would inspire his aggression.
ILIs rarely, if ever, take it upon themselves to display emotional, social, or physical initiative. To engage other people, especially in unfamiliar circumstances, can be a harrowing task for ILIs, and one from which most ILIs usually try to refrain. Nonetheless, ILIs are often treated with uncertainty or dubitation by most others due to their large inability to give off clear emotional data; ILIs may appear overly polite, formal, and robotic in social situations. ILIs seeking emotional ties with individuals may find themselves forced to take the initiative with others, a task for which even friendly ILIs are poorly equipped and bogged down with uncertainty. Even when ILIs do take some initiative upon themselves, they almost never succeed in reaching a depth of emotional connection which satisfies them.
Realization and development of Fi in ILIs represents a process of growth. Some ILIs with minimally developed Fi can be far less aware of the importance of lasting emotions, and can appear far more insensitive, unfriendly, and antagonistic.
