Why Colleges Used to Take Nude Photos of Their Students

The video discusses the history of posture photos taken at Ivy League schools from the 1880s to the 1970s, initially for health reasons. William Sheldon used these photos to link body types to personality traits, a theory known as constitutional psychology.

Today, somatotypes are used for fitness, not personality, and modern psychology relies on mind-based tests like the Big Five.
