About this episode

This episode explores the evolution of personality tests from their origins in World War I to their use in modern employment practices.

This week we learn how personality tests went from determining if you could handle PTSD in WW1 to whether or not you could be employed by a Fortune 500 company. A listener emails tells the story of that time Gary Larson had to explain a not so complicated Far Side comic to his fans.
