The Algorithm That Knew You Better Than Your Wife

A computer needed only 70 Facebook likes to understand your personality better than your closest friends.

In this episode of Signals & Shadows, we explore the OCEAN personality model, the research that revealed how digital behavior can predict human psychology, and how Cambridge Analytica transformed academic psychometrics into one of the most controversial political targeting operations in modern history.
