01:00:00 Lisa Feldman Barrett discusses the idea that the brain operates without our awareness, constantlyasking itself hypothetical questions and selecting from a range of possible answers. The network involved in this process is active all the time, except when we are asleep.

01:15:00 Lisa Feldman Barrett discusses how the brain constructs concepts, including emotions, by predicting which features are common among instances of a given concept. This process involves constructing a prototype, which is a representation of the most typical instance of the concept, and then reading off features of the prototype when asked for the concept.
01:20:00 Lisa Feldman Barrett argues that concepts, such as species, are a type of conceptual category, and that this concept is based on a function. Concepts vary in their features, but they share a common function. This concept is what allows humans to make civilization.

01:40:00 Lisa Feldman Barrett discusses how the brain makes predictions through past experience and what happens when different cultures come into contact. She also discusses the effects of social media on society.
01:45:00 Lisa Feldman Barrett discusses how the brain works and how we can train ourselves to better predict outcomes by adding experiences to our brains. She also discusses the concept of a "stereotype" of black men in the United States, and how it has changed over time.
