About This Book
What happens inside a trader's body when markets spike or crash? John Coates, a former Wall Street trader turned neuroscientist, argues that financial risk-taking isn't purely rational — it's biological. Hormones like testosterone and cortisol surge and retreat in response to wins and losses, quietly distorting judgment, amplifying confidence, and deepening panic in ways that traders rarely recognize and economists almost never account for. The implications reach far beyond trading floors: this is a book about how our bodies shape the decisions we think our minds are making.
Coates writes with the authority of someone who has lived on both sides of this story — as a practitioner and as a researcher — and that dual perspective gives the book an unusual texture. The science is rigorous but never dense, woven together with vivid scenes from trading rooms that feel observed rather than imagined. The structure moves fluidly between biology, psychology, and market history, each chapter building a case that feels genuinely surprising. Readers drawn to behavioral economics will find this a more visceral, embodied take on why smart people make catastrophic decisions.
