What most people do: In the 1944 study, 33 people out of 34 told a story.

There are only geometric shapes moving around. Yet almost everyone sees a chase, a bully, a couple, an escape.

In 1944, Fritz Heider and Marianne Simmel showed this short film to students: out of 34, only one described shapes; all the others told a story, with characters and intentions.

Your brain looks for intentions everywhere. That is what lets you understand other people, and cry at the movies.
