The Myth of the Rational Investor

by Justin Fox

First published 2006

Justin Fox examines the widespread belief that investors make rational choices based on careful analysis of available information. He traces how this assumption became central to modern financial theory despite mounting evidence that human psychology plays a larger role in market behavior. Fox shows how emotions, cognitive biases, and social pressures shape investment decisions in ways that contradict the rational investor model. The book explores decades of research in behavioral economics and psychology that reveals systematic patterns in how people actually make financial choices. Fox argues that understanding these psychological factors offers a more accurate picture of how markets really work than traditional economic models suggest.
