Why does your intelligent, capable brain keep leading you into the very same mistakesagain and again?

You are not irrational by accident. Your mind fails in regular, predictable patterns: it anchors on random numbers, drifts toward the middle option, overreacts to the word “free,” clings to what it owns, and rewrites your values the moment emotion runs hot. In Smart Brain, Foolish Choices, neuroscientist Theo Whessler assembles a compact field guide to the traps your brain sets for you every single day.

Grounded in landmark behavioral sciencefrom Kahneman and Tversky to the psychology of placebos, reciprocity, and procrastinationthis book translates decades of laboratory research into practical rules you can actually use. The promise is direct: once you can name these traps, you can stop falling into them twice.

Inside, you’ll discover:

• How anchoring, decoys, and the “tyranny of the middle option” quietly steer choices you believe are your own
• Why “free” shuts down your judgmentand how hidden costs in time, attention, and data slip past you
• The hot-cold empathy gap that lets emotion rewrite your values in real time
• Why keeping every option open secretly drains your focus, money, and peace of mind
• How expectations, brands, and price tags change not just what you say you like, but what you genuinely experience
• Practical commitment devices, checklists, and choice-architecture tools to outsmart your own biases

Stop trying harderstart redesigning the conditions in which you think, and make better choices almost automatic.
