Human behavior often feels unpredictable—until you start noticing the patterns.

People repeat themselves.

We return to familiar habits, respond to similar situations in similar ways, make predictable assumptions, and recreate patterns we may not even recognize. The same forces that shape one decision can influence hundreds of others.

The Patterns of Human Behavior explores the recurring structures behind how people think, decide, react, communicate, learn, and change.

At the center of the book is the idea of The Reusable Mind: the ability to recognize useful patterns of thinking and apply them across different situations rather than treating every problem as completely new.
