Now that we have established the concept of opposing rhythms for statics, it would be in our best interest to observe it in dynamics. As our example, I'll be using the EIE and the IEI, Mirror types.
Dynamic types see effects of things, they perceive what is affecting an object or situation (Ip), and they take action to affect something in their own best interest (Ej). Whereas with the Static Rhythms (Ij and Ep), where we saw order versus chaos in a simplified form, the antithesis here is taking action (participating) versus observing (spectating). You can not participate in something and spectate something at the same time; thus, Ej's naturally take the playing field while Ip's prefer to view the situation from an outside perspective.
Now, as before with statics in establishing order by identifying chaos, to enact change and to affect something, you need to observe how a situation is progressing currently if you wish to actually do so correctly. Thus, Ej's naturally rely on a creative Pi element to allow them to create change and affect a system. Let's take a look at the EIE.
The EIE's lead element is an Ej element, extraverted ethics. Thus, the EIE is concerned with affecting people and causing change in the social landscape, being able to influence people emotionally. To do this, however, the EIE, being an intuitive, locks into the internal rhythm of a person (Ni), their psychological state, how they emotionally operate, so that they can perceive the system and know precisely what is already happening in front of them. Then, they can take action and influence the person correctly and with great expertise. In locking into the internal rhythm of a person, however, the EIE unfortunately fails to notice tangible changes in a person that signify emotional states, and may not, for instance, notice how the clothes a person is wearing signify their internal state, nor do they actively notice how physically comfortable the person is, nor any physical cues of discomfort (though they are able to sense it psychologically through the analysis of their words, most of the time, they just don't recognize the physical signals), displeasure, or any other physical expression of emotions. Thus, due to the fact that they observe the internal rhythm and the underlying meanings produced by a person, they subsequently fail to notice physical, tangible changes in a person constantly, and thus build a sort of phobia around information related to it (Si), due to the fact that their use of Introverted Perception is fully directed at Introverted Intuition.
Now, to understand the other perspective of Ip sociotypes, we turn to the IEI.
The IEI, belonging to the Ip sociotypes, is concerned foremost with the passive observation of situations. Geared to Intuition, this passive observation is the cognizance of fluctuating, hidden meanings, and the internal rhythms of situations or things. Being an Ethical sociotype, Introverted Intuition is applied to the sphere of Extraverted Ethics (Ni-, Fe+) and is thus oriented towards perceiving the internal rhythms of people, the dynamics of the social realm (and even spiritual), and how people are affecting each other. Unlike the EIE, however, the IEI is unconcerned with actually affecting people so much as understanding people on a deeper, subjective level, how they operate. The EIE simply wants to know how people operate for the sole purpose of being able to affect them somehow (Creative Ni), the IEI wants to know how people operate just because, and so that the IEI can fully understand human nature, and/or the situation that is unfolding presently in the social sphere (rather than trying to affect it, Lead Ni). To help them understand how a person is operating, however, they must either do one of two things. The first way is by simply not acting and only observing a person, but this way is troublesome considering that the sole information supply is from introverted intuition. The other way it to step in and affect people and then to step back out and observe the person's reaction, so that the IEI will better be able to hone in on the internal rhythm and deeper psychological state of the person. Thus, while the Introverted Irrational IEI doesn't prefer to take action, when he or she does, it will be in affecting the social sphere and people, which subsequently means that they will entirely avoid situations where they must affect impersonal, logical systems by actions, as taking action in that sphere truly represents the opposing rhythm of Ej to the IEI.
Fe - Affecting People Emotionally and Socially
Ni - By [Passively] Observing the Internal Rhythms of People to Understand the Conceptual Situation
Te - By Ignoring How Information Impersonally affects Logical Systems
Si - And By Avoiding the Immediate Changes in the Observable World to Understand the Physical Situation
Ni - Observing the Human Condition, Internal Rhythms, and the Conceptual Situation
Fe - By Affecting People Emotionally and Socially
Si - By Ignoring the Physical Situation, and the Immediately Observable Changes in Reality
Te - And By Avoiding How Information Impersonally affects Logical Systems
Do note that, in this format, the failure in the Role function is the reason for the success in the Lead function, and the failure in the Vulnerable function is the reason for the success in the Creative function. It should then be looked at in this way:
"The LSI is good at Establishing Logical Order in the Chaos of the Physical Environment because the LSI Doesn't Notice, Concern Itself With, and Ignores Ethical Qualms and the Conceptual Chaos in the World of Speculation."
Success in personality, then, is determined by a sociotype's inattention to the problems of the Super-Ego block. If the LSI had to face Ethical Qualms, then the LSI would be unable to Establish Logical Order, as he must now not only organize things logically but ethically at the same time (which would get absolutely nothing done efficiently). LSI, while despising situations where they must categorize things as right or wrong, or realize the ethics of their own establishment of order, are concerned with how this establishment of order is and will be affecting people (Fe+ Seeking).
