Why People Believe Weird Things

Why People Believe Weird Things is the science writer and skeptic Michael Shermer's study of pseudoscience, superstition, and irrational belief. Its central claim is that such beliefs are not simply failures of intelligence but products of how the mind ordinarily works, pattern-seeking, confirmation bias, and the human hunger for meaning, which lead even capable people to embrace unfounded ideas.

The method combines case studies with cognitive explanation. Shermer surveys phenomena such as alien abduction accounts, creationism, and recovered-memory claims, then accounts for their persistence through the psychology of belief, arguing that "smart people believe weird things" because intelligence is often deployed to defend conclusions reached for non-rational reasons.

The book is a representative work of the modern skeptical movement and a counterweight to the consciousness and manifestation currents elsewhere in this collection. It shifts the question from whether weird claims are true to why they are believed, grounding the inquiry in evidence and the study of mind.
