At certain moments, they adopt false beliefs with confidence, reinforce them socially, and act on them with extraordinary conviction.First published in 1841, Extraordinary Popular Delusions and the Madness of Crowds by Charles Mackay remains one of the most influential accounts of collective belief and collective error. Rather than offering abstract theory, Mackay documents how speculative manias, social enthusiasms, and popular delusions take hold, escalate, and eventually collapse.The book is widely known for its treatment of financial bubbles such as Tulipomania, the Mississippi Scheme, and the South Sea Bubble. Yet its scope extends far beyond markets. Mackay traces recurring patterns of imitation, escalation, moral certainty, and social reinforcement across religion, superstition, prophecy movements, and public panics.This Annotated Edition includes a substantial original introduction and an added section titled Editorial Annotations and Critical Commentary, which:Examines where modern historians have revised or challenged Mackay’s claimsClarifies the economic and political context of major speculative episodesIdentifies recurring psychological mechanisms underlying mass belief formationDiscusses the limitations of Mackay’s Victorian perspectiveThe complete, unabridged original text is preserved, with light modernization of spelling and formatting for clarity. No attempt has been made to alter Mackay’s arguments, but this edition provides additional context to help contemporary readers interpret them critically.This is not a book of investment advice. It is a historical study of how crowds form convictions, reinforce them socially, and sustain them even in the face of contrary evidence. Read more
