The Tribal Mind

How group identity overrides individual intelligence, every time.You have watched two intelligent people look at the same facts and walk away with opposite, confident conclusions. You have felt loyalty to a team, a brand, or a cause that, if you're honest, you can't fully explain. You have wondered why smart people seem to get more certain, not less, once a question touches something they belong to.The Tribal Mind argues that none of this is a failure of character or intelligence. It is the oldest, cheapest, most reliable piece of software the human brain runs: an instinct that sorts the world into us and them so fast, and on so little evidence, that most of us never notice it happening.Drawing on psychology, neuroscience, history, and economics, this book traces a single mechanism as it moves from the schoolyard to the boardroom, from a summer camp rivalry to a nation at war, from a taste test to a newsfeed engineered to keep you angry. Along the way it asks a harder question than most books in this space are willing to ask: when is your suspicion of the other side bias, and when is it simply accurate?This is not a book about why other people are wrong. It is a book about the machinery every reader is running right now, without permission and without pause, and what it actually costs to see it clearly.No checklists. No easy fixes. Just a clearer view of a mechanism you were always going to be standing inside of
