About Us


Personality Type in Depth was created in 2010 by Carol Shumate and Mark Hunziker to publish scholarship that bridges the gap between psychological type and depth psychology by exploring the interaction of the conscious and unconscious aspects of psychological type.

Articles undergo rigorous review and are edited by professional editors and writers. In keeping with our mission to promote research and education relating to depth typology theory and practice, subscription is free, and all issues are accessible to the public online.
