This book investigates the core question of how students and laypeople can effectively distinguish between legitimate psychological research and pervasive pseudoscience. Keith E. Stanovich, a prominent researcher in cognitive science, utilizes his extensive academic background to provide a framework for evaluating empirical evidence. He argues that critical thinking is not an innate trait but a set of skills that must be applied to the interpretation of psychological claims found in media and popular culture.

This text is widely regarded as a standard introductory resource for undergraduate psychology students seeking to develop scientific literacy. The framing suggests a highly accessible yet rigorous approach to the discipline, prioritizing the development of analytical habits over the rote memorization of psychological theories.
