Is socionics a hard science?
No, not in the sense of being based on experimentally obtained data and repeatable experiments. Augusta, the founder of socionics, emphasized that all of her claims were based on observation and study and that she was simply elaborating on Jung’s typology. If we take people whose types have been correctly identified, it is possible to obtain various hard data on behavior and interaction between them. However, the main weakness of socionics as a potentially empirical science is that socionic types themselves cannot be determined mechanically, but must be identified by a human specialist, which introduces subjectivity issues. As a conceptual structure socionics is easily supportable logically.
