Self-help ✦ Penny’s Take
Memoirs of Extraordinary Popular Delusions
CHARLES. MACKAY · 2025
78/100
👍 Worth It
Mackay's 1841 survey of collective human folly remains remarkably readable and enduringly relevant — from tulip mania to the Crusades, the case studies are both entertaining and sobering as a mirror on how crowds override individual reason. This reprint edition adds nothing new, but the original text is simply good and the ideas have only grown more pertinent in the age of social media.
