Maybe not for you if...

You're looking for a self-help book with actionable steps to change your life. This is pure understanding, not practical application.
You prefer shorter reads. At 795 pages, this rewards patience and deep engagement.
You want simple answers. Sapolsky's central argument is that human behaviour is wildly complicated and determined by countless interacting factors.

About this book

Behave examines human behavior across multiple scientific disciplines. Robert M. Sapolsky, a neuroscientist and primatologist, explores the biological and psychological foundations of why people act as they do, both constructively and destructively. The book addresses complex questions about tribalism, xenophobia, hierarchy, competition, war, and peace. Sapolsky synthesizes current research to uncover the underlying mechanisms driving human actions and social patterns. The work draws on findings from neuroscience, primatology, and related fields to provide a comprehensive look at the science of human behavior.
