Last week, we explored with Steven Sloman his revolutionary approach to thinking. Thinking, he tells us, is a social activity that we do with others, never alone. We are all part of a community of thinkers where we divide the work of thinking. When we build a home, for example, we need many different kinds if experts each of whom knows what they’re doing.

On this episode, we’re going to explore the wide-ranging implications of being part of a community of thinkers and learners. Welcome to Part Two of my conversation with Steven Sloman, the co-author with Philip Fernbach of a compelling new book, The Knowledge Illusion: Why We Never Think Alone. Steven Sloman, is a professor of cognitive, linguistic, and psychological sciences at Brown University. He is also the editor in chief of the journal Cognition.
