Extraordinary Popular Delusions and the Madness of Crowds is a history of popular folly by Scottish journalist Charles Mackay, first published in 1841. The book chronicles its subjects in three parts: "National Delusions", "Peculiar Follies", and "Philosophical Delusions". Despite its journalistic and rather sensational style, the book has gathered a body of academic support as a work of considerable importance in the history of social psychology and psychopathology. The subjects of Mackay's debunking include economic bubbles, alchemy, crusades, witch-hunts, prophecies, fortune-telling, magnetisers (influence of imagination in curing disease), shape of hair and beard (influence of politics and religion on), murder through poisoning, haunted houses, popular follies of great cities, popular admiration of great thieves, duels, and relics. Present day writers on economics, such as Andrew Tobias and Michael Lewis, laud the three chapters on economic bubbles. 1] Scientist and astronomer Carl Sagan mentioned the book in his own discussion about pseudoscience, popular delusions, and hoaxes. In later editions Mackay added a footnote referencing the Railway Mania of the 1840s as another "popular delusion", of importance at least comparable with the South Sea Bubble. Odlyzko has pointed out, in a published lecture, that Mackay himself played a role in this economic bubble, as leader writer in the Glasgow Argus; and wrote on 2 October 1845 that "There is no reason whatever to fear a crash".
