Cousins with MBTI, however, they do not want to associate with
one another. Probably a pseudoscience.
Socionics claims there to be 8 information elements (IMEs) and
16 types. These 16 types of information metabolism(TIMs) interact with
one another in 16 ways.
Each TIM possesses all 8 IMEs, in different slots in their cognition. They value certain IMEs above others, and they are stronger in certain IMEs than others.
These 16 types are also divided into 4 quadra of 4, each sharing the same valued IMEs. Those who share a quadra are where long term relations are most likely to flourish. They are the Alpha, Beta,
Gamma and Delta Quadra.
Warning: Socionics is rather complex.
Please do not try at home. Unless you want to. Then
maybe you can.
