“In The Knowledge Illusion, the cognitive scientists Steven Sloman and Philip Fernbach hammer another nail into the coffin of the rational individual… positing that not just rationality but the very idea of individual thinking is a myth.” —The New York Times Book Review
“Sloman and Fernbach offer clever demonstrations of how much we take for granted, and how little we actually understand… The book is stimulating, and any explanation of our current malaise that attributes it to cognitive failures—rather than putting it down to the moral wickedness of one group or another—is most welcome. Sloman and Fernbach are working to uproot a very important problem… [The Knowledge Illusion is] written with vigour and humanity.” —Financial Times
“The Knowledge Illusion is at once both obvious and profound: the limitations of the mind are no surprise, but the problem is that people so rarely think about them… In the context of partisan bubbles and fake news, the authors bring a necessary shot of humility: be sceptical of your own knowledge, and the wisdom of your crowd.” —The Economist
“A breezy guide to the mechanisms of human intelligence.” —Psychology Today
“In an increasingly polarized culture where certainty reigns supreme, a book advocating intellectual humility and recognition of the limits of understanding feels both revolutionary and necessary. The fact that it’s a fun and engaging page-turner is a bonus benefit for the reader.” —Publishers Weekly
“An utterly fascinating and unsettling book, The Knowledge Illusion shows us how everything we know is bound together with knowledge of others. Sloman and Fernbach break down many of our assumptions about science, how we think and how we know anything at all about the world in which we live. Despite the wide-scale deconstruction, the authors are upbeat… Anyone engaged in the work of nurturing healthy and flourishing communities will ultimately have to wrestle with the questions posed in this book. Sloman and Fernbach help us to do so gracefully, acknowledging the truth of how little we know, and finding hope in this precarious situation.” —Relevant Magazine
“We all know less than we think we do, including how much we know about how much we know. There’s no cure for this condition, but there is a treatment: this fascinating book. The Knowledge Illusion is filled with insights on how we should deal with our individual ignorance and collective wisdom.” —Steven Pinker, Johnstone Family Professor of Psychology, Harvard University, and author of How the Mind Works and The Stuff of Thought
“I love this book. A brilliant, eye-opening treatment of how little each of us knows, and how much all of us know. It’s magnificent, and it’s also a lot of fun. Read it!” —Cass R. Sunstein, coauthor of Nudge and founder and director, Program on Behavioral Economics and Public Policy, Harvard Law School
