Это последняя книга Карла Сагана, астронома, астрофизика и выдающегося популяризатора науки, вышедшая уже после его смерти. Эта книга, посвященная одной из его любимых тем — человеческому разуму и борьбе с псевдонаучной глупостью, — своего рода итог всей его работы. Мифы об Атлантиде и Лемурии, лица на Марсе и встречи с инопланетянами, магия и реинкарнация, ясновидение и снежный человек, креационизм и астрология — Саган последовательно и беспощадно разоблачает мифы, созданные невежеством, страхом и корыстью.
Sagan presents a set of tools for skeptical thinking which he calls the "baloney detection kit". Skeptical thinking consists both of constructing a reasoned argument and recognizing a fallacious or fraudulent one. In order to identify a fallacious argument, Sagan suggests the employment of such tools as independent confirmation of facts, quantification, and the use of Occam's razor. Sagan's "baloney detection kit" also provides tools for detecting "the most common fallacies of logic and rhetoric", such as argument from authority and statistics of small numbers. Through these tools, Sagan argues the benefits of a critical mind and the self-correcting nature of science can take place.
Sagan provides a skeptical analysis of several examples of what he refers to as superstition, fraud, and pseudoscience such as witches, UFOs, ESP, and faith healing.
