we all think we know more than we actually do.
Humans have built hugely complex societies and technologies, but most of us don’t even know how a pen or a toilet works. How have we achieved so much despite understanding so little? Cognitive scientists Steven Sloman and Philip Fernbach argue that we survive and thrive despite our mental shortcomings because we live in a rich community of knowledge. The key to our intelligence lies in the people and things around us. We’re constantly drawing on information and expertise stored outside our heads: in our bodies, our environment, our possessions, and the community with which we interact—and usually we don’t even realize we’re doing it.
The human mind is both brilliant and pathetic. We have mastered fire, created democratic institutions, stood on the moon, and sequenced our genome. And yet each of us is error prone, sometimes irrational, and often ignorant. The fundamentally communal nature of intelligence and knowledge explains why we often assume we know more than we really do, why political opinions and false beliefs are so hard to change, and why individual-oriented approaches to education and management frequently fail. But our collaborative minds also enable us to do amazing things. The Knowledge Illusion contends that true genius can be found in the ways we create intelligence using the community around us.
praise for the knowledge illusion:
“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
“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 skeptical of your own knowledge, and the wisdom of your crowd.”
