Hans Eysenck was one of the biggest names in psychology. Was he also a scientific fraudster? Long after his death, allegations resurfaced about his late-career studies, which either contained some of the most impressive findings in medical history, were a terrible mistake… or were the result of something much more sinister.

In this paid-only episode of The Studies Show, Tom and Stuart tell the shocking—and often darkly amusing—tale of Hans Eysenck and his enigmatic collaborator, Ronald Grossarth-Maticek. If you’ve enjoyed the recent episodes on personality, on psychotherapy, and on scientific fraud, how about a story that combines them all into one totally disastrous indictment of the way we do science?
