According to J. Horwood, and A. Maw socionics is a science developed by Ausra Augustinaviciute in the 1970s. Augustinaviciute and her colleagues worked with Carl Jung's personality typologies to develop personality-based relationship profiles. It was found that the nature and development of interpersonal relationships (both professional and personal) are far from random. Instead, they are based on how well suited each individual's psychological profiles are to one another, allowing Augustinaviciute to develop 16 'socionic types' predicting and describing the interpersonal relationships between any combination of Jung's personality types.
