Summary of The Knowledge Illusion

The Knowledge Illusion: Why We Never Think Alone, written by cognitive scientists Steven Sloman and Philip Fernbach, explores how our individual and collective intelligence shapes our understanding of the world. It argues that the human capacity for knowledge is ultimately limited and draws on research from cognitive science, neuroscience, and psychology to investigate cognitive illusion, or how we overestimate our own understanding and underestimate the complexity of the world around us. The authors explain how we can use collective intelligence to make better decisions and ultimately improve our lives.
