What is Socionics?

Socionics is a theory of personality and human interaction developed in the 1970s by Lithuanian researcher Aushra Augusta. It describes 16 types by how each one takes in and processes information, and names the dynamic between every pair of them, from Duality to Conflict. That focus on what happens between two people is what sets it apart from MBTI.
