Why Your Brain Secretly Sabotages Every Decision You Make (And How to Fight Back)
Using the ‘Think Twice’ tool for stronger decision-making and fewer costly mistakes
You think you’re smart, right?
You weigh your options. You consider the facts. You make logical choices.
Simple, right?
But… Your brain is lying to you, as does mine. Right now. And it’s been doing it our entire lives.
Your brain isn’t broken. It’s efficient. We evolved to survive, not to be right.
In our ancestors’ days, fast decisions saved energy and helped to avoid danger. Slow decisions took time and fuel. So the brain built a shortcut system that works most of the time, but fails in predictable ways.
Modern life runs into these failure points every day.
Slow thinking is expensive. Your brain, at about 2% of your body mass, uses a lot of your body’s energy at about 20%. As such, it has evolved to conserve fuel — largely by running on automatic patterns. It saves its slow, careful mode for moments when it’s forced: a hard problem, a high-stakes choice, a strategic board game.
