Club
Clubs is a small groups of four types that share the same two traits on the intuition / sensing and logic / ethics dichotomies. They are also often called "occupational attitudes" (установки на род деятельности - Gulenko's term). Augusta and Reinin were the first to apply this concept. There are four clubs in the socion:
- Humanitarians: intuitive and ethical (NF), or IEE, IEI, EIE, and EII.
- Socials: sensing and ethical (SF), or SEE, SEI, ESE, and ESI.
- Pragmatists: sensing and logical (ST), or SLE, SLI, LSE, and LSI.
- Researchers: intuitive and logical (NT), or ILE, ILI, LIE, and LII.
The same four relations exist between the types of any club: identity, mirror, extinguishment/contrary, and quasi-identity.
Clubs are often a common nucleus of spontaneous social interaction (as opposed to "non-spontaneous" as in work, study etc) in modern western societies, and therefore a very common point of formation for social groups, more so than quadras since spontaneous social interaction with new acquaintances tends to be based on common activities and interests if not based on extension of one's close social circle, where quadras are more relevant.
What leads to club-based groups, however, are merely the common interests and activities; the clubs tend to cease to function as any unit as soon as the interactions between their members move beyond those common interests and activities, when the quadra interactions will naturally take over.
Within the same quadra, Mirrors and Identicals belong to the same club. This explains the high percentage of Mirror couples.
