Synopsis

Human reasoning is remarkably shallow - in fact, our thinking and justifications just scratch the surface of the true complexity of the issues we deal with. The ability to think may still be the greatest wonder in the world (and beyond), but the way that individuals think is less than ideal. In The Knowledge Illusion, Sloman and Fernbach show that our intelligence resides not in individual brains but in the collective mind. To function, individuals rely not only on knowledge that is stored within our skulls but also on knowledge stored elsewhere, be it in our bodies, in the environment or especially in other people. Put together, human thought is incredibly impressive, but at its deepest level it never belongs to any individual alone.

And yet the mind supports the most sublime, incredible phenomenon of all: consciousness. How can any of this be possible with a mind that is so imperfect? This is one of the key challenges confronted in this book. The Knowledge Illusion ties together established scientific facts whilst also considering what the mind is for. Understanding why the mind is as it is, and what it is for, will show why we need to consider it as extending beyond our skulls; why we should think about 'the mind' as far more than an extension of the brain but as an emergence from multiple brains interacting. Simply put, individuals know relatively little, but the human hive that emerges when people work together knows a lot.

In the media

"Cognitive science attempts to understand the workings of the individual mind. In this brilliant book, Steven Sloman and Philip Fernbach show us that what cognitive science has learned is how much the individual mind depends on the minds of others. No matter how smart we are, as individuals we know (almost) nothing. Reading this book will inspire you to cultivate your own expertise, but even more, it will inspire you to seek out and appreciate the expertise of others. This book is a blueprint for an enlightened society."
Barry Schwartz, author of The Paradox of Choice, Practical Wisdom, and Why We Work.
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.
Financial Times
Using a mixture of stories and science from an array of disciplines, the authors present a compelling and entertaining examination of the gap between knowledge one thinks one has and the amount of knowledge actually held in the brain, seeking to "explain how human thinking can be so shallow and so powerful at the same time" ... 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.
