The history of how we diagnose psychological issues is long, interesting, and several kinds of messed up. We begin to take that apart today. I was joined for this conversation by Tehya Fencik (TK), creator & host of "For The Love Of History Podcast." As a historian, TK found incredible information about therapeutic communities in the early 1900s. 

"The Statistical Manual for Use of Institutions for the Insane" is a text written in 1918 and an early attempt at categorizing mental health disorders. While it never caught on, it represents an experiment in the type of thinking that led to modern diagnostic practice.
