Rebecca Saxe wants to know how our brains learn to be social.

More precisely, Saxe, an associate professor of cognitive neuroscience in MIT’s Brain and Cognitive Sciences Department, has built her career by trying to grasp how we make judgments about other people’s thoughts, a faculty dubbed Theory of Mind (ToM).
