In the Season 3 finale, Cristina tells Martin about the bizarre and surreal experiments of John Calhoun. Calhoun set up entire self-contained worlds for rats and mice, confirming societal fears about crowding, overpopulation, and weak-willed mice-men.

In this episode, Cristina tells Martin about a relatively recent article published in Science claiming that humans would rather do anything in the world, including shock themselves, than sit in a room and think their own thoughts.

Cristina covers work by Solomon Asch, an early teacher of Stanley Milgram, and his examination of conformity and the forces that induce somebody to either follow a crowd or break free from it.

In this episode, Martin talks about a pivotal paper from 1968 that fundamentally changed how people think about and treat Tourette syndrome. Haloperidol was newly introduced, tics were reduced, and researchers proposed that Tourette syndrome could be a neurological disorder rather than a moral failing.

This is part 2 of 2 of the pseudopatient study conducted by Rosenhan in the 1970s. In this episode, Martin and Cristina talk about the recently released book and paper both documenting the scientific fraud underlying "On Being Sane in Insane Places."

In this episode, Martin and Cristina cover the famous Marshmallow Study, a study of delayed gratification in children. Since it's rise in popularity, the Marshmallow Study has been touted as a predictive test that could accurately categorize people into low and high achievers, people willing to delay their own gratification for long term gain and impulsive people unwilling to wait for bigger rewards. What were the parameters of the original study? What was going on at Stanford University in the 1970s?

Season 3 Episode 1! We start with the famous pseudopatient study, titled "On Being Sane in Insane Places," conducted by David Rosenhan, published in Science on Jan 19, 1973. In this study, Rosenhan asked questions about psychiatric diagnosis and the real differences between normal and abnormal people. His work was a part of and bolstered the growing anti-psychiatry movement, ushering in a complete revision of the DSM and conversations about mental health treatment in America. If sanity and insanity exist, how shall we know them?
