Why Smart People Do Dumb Things

Smart people who keep tripping over the very same thing. They buy what they don't need. They cling to a plan that was never going to work. They're certain they're right — and spectacularly wrong. And afterward, the same quiet murmur: "Why on earth did I do that?"

This is a book about that "why" — and the good news is that it isn't because you're foolish. Your brain simply comes with a handful of holes built in. They're the same for all of us, they've barely changed in thousands of years, and "just being careful" doesn't switch them off. But once you can name a trap, you can stop yourself before you step in.

A calm, beginner-friendly tour of the mental traps that catch clever people most: - Loss aversion — why losing hurts more than winning feels good - Anchoring — how the first number quietly sets all the rest - Sunk cost — throwing good money after money that's already gone - Confirmation bias — seeing only what you already believe - Social proof — "everyone's doing it," so it must be right - Overconfidence, framing, hindsight, and the survivors you can't see

No equations, no jargon, no psychology degree required — just a string of small, almost laughable mistakes and the hard-won wisdom that untangles each one. Running underneath is one simple habit this book builds in you, the question that saves the day: "Am I on autopilot right now?"

You don't need to be smarter. You're plenty smart already. You just need the owner's manual for the brain you've got.
