Facial expression recognition is mediated by a distributed neural system in humans that involves multiple, bilateral regions. There are six basic facial expressions that may be recognized in humans (fear, sadness, surprise, happiness, anger, and disgust); however, fearful faces and surprised faces are easily confused in rapid presentation.

In today's episode Jake explains how the concept of surprise and fear is relevant to many aspects of human behavior. It also affects beliefs about other events. When a person takes an unexpected stance that violates his or her self-interest, the person’s arguments are surprising and quite often more persuasive.
