Keith E. Stanovich is a Canadian cognitive scientist and professor emeritus at the University of Toronto, known for his research in critical thinking, rationality, and reading development. His work distinguishes between intelligence and rational thought, arguing that rational thinking is a separate and often overlooked skill. In The Bias That Divides Us, he explores "myside bias" and its role in political and cognitive polarization. Stanovich's insights have influenced educational psychology, behavioral science, and decision-making theory. His accessible and research-driven writing has made him a leading voice in understanding the limits and fallibilities of human reasoning.
Keith Stanovich explores “myside bias,” a cognitive tendency where people favor information that supports their pre-existing beliefs. The book shows how this bias undermines rational discourse, fuels political polarization, and distorts decision-making—even among highly intelligent individuals. Stanovich distinguishes between intelligence and rational thinking, arguing that education alone doesn’t guarantee cognitive objectivity. Through accessible research and examples, he offers strategies for cultivating rationality and intellectual humility. The Bias That Divides Us is a vital contribution to understanding how psychological blind spots hinder progress and how we can overcome them to think more clearly and engage more constructively.
