A strong example of an SSS that is fundamental to socionics and concerns the need for easy communication during interpersonal interactions, focusing on the role of dual-seeking functions in the determination of type during early childhood: The undeveloped id awakens and begins to explore the environment. Upon encountering others, the most pleasing IM elements expressed by people (perhaps the ones used by the others to convey understanding and communication or for comforting a baby) are reinforced and become the superid, which is essentially receptive and attentive to the wants of others as the id learns behaviors by imitation and identification (for static types the id learns to associate the extroverted judging of others with itself because it is directed at the id, and becomes an introverted judger; likewise the id associates introverted perceiving in others with extroverted perceiving in itself and becomes an extroverted perceiver); when the id is reproached for not being 'better' at the quasi-identical functions of the superid (which are suppressed in order to give more attentive power to the superid) then the id, which has only IM elements with which to relate and organize, associates the consistently negative functions in itself with inferiority and they collectively become the superego (which begins to take precedence over the superid during the Oedipus Complex). These are constantly accommodated by ego functions, which are used to exploit perceived weaknesses in the superego that eventually accumulate with use. The remaining unused IM elements remain in the id, where they are available at the 'desire' of the id but are not used continuously or systematically. Thus the
Primary SSS focuses on the most efficient fixation of the attention on others (which happens to involve dual-seeking functions that are both least resistant and most reinforcing of continuous attention), and the
Auxiliary SSS is the exploitation of the superid by the ego. One might ask, 'Why then does
not seek
?' This has to do with selfish exploitation. Obviously one extreme in any dichotomy is best exploited by the other (it is not so easy to hide an element-specific SSS from someone who already understands its subtleties and advantages). This tendency is present even in the DNA, where the X chromosome is constantly trying to manipulate the weaker Y chromosome for its own selfish benefit. There is also a symbiotic benefit in complement functions, where positive long-term relations (requiring functional territory as personal space) are naturally selected over others. In a sexually reproducing, socially interacting species as ours, it is not surprising that fitness trends are replicated in the psyche (culminating perhaps in genetic dual-seeking predispositions to aid in sexual selection and conspecific diversity). I hope that from this discussion that it has become conspicuously evident that the superid is ultimately the most important factor in early type determination, because it dictates which IM elements will be used for understanding other people (which is the most important behavior for both young children and for social relations in general, and is also powerful factor in the manifestation of learning preferences and disabilities), and subsequently for adapting to social constraints.
