Most of your decisions aren’t actually “decisions”—they’re automatic reactions.

This book breaks down how your mind operates in two modes: one that’s fast, emotional, and impulsive, and another that’s slow, logical, and deliberate. The problem? You rely too much on the fast one without realizing it.

That’s why people misjudge risks, fall for biases, and make poor choices—even when they think they’re being rational.

Once you understand how these two systems work, you start catching your own thinking mistakes. And that’s where the advantage is—because better thinking leads to better decisions, and better decisions compound over time.
