What is Socionics?

Socionics is a theory of personality and human interaction developed in the 1970s by Lithuanian researcher Aushra Augusta. It describes 16 distinct psychological types, each defined by how they take in and process information, and maps the relationships between them into 16 intertype relations ranging from deeply complementary to fundamentally conflicting.

Where MBTI focuses primarily on individual personality traits, Socionics goes further. Its central contribution is a detailed model of how different types interact with each other. The 16 intertype relations cover everything from Duality (the most complementary pairing) to Conflict (the most incompatible). That is what makes the system distinctive and, for many people, immediately useful.

Two people of the same type will understand each other completely. They will also be largely unable to help each other in the ways that matter most.

If you are coming from MBTI, the type codes will look familiar. The underlying theory is different enough to reward learning it on its own terms.
