Why Crowds Go Mad: The Insane Truth About Financial Bubbles

Extraordinary Popular Delusions and the Madness of Crowds

Charles Mackay

Slide 1: The Illusion of Sanity You think you are rational. You are entirely wrong. Humans think in herds. We go crazy in crowds. We only recover our senses slowly, and one by one. Welcome to the brutal truth of mass hysteria. Slide 2: The Masterpiece of Madness Book: Extraordinary Popular Delusions and the Madness of Crowds. Author: Charles Mackay, a legendary Scottish journalist. He exposed the ultimate flaw in human psychology centuries ago. When greed takes over, even geniuses turn into degenerate gamblers. Slide 3: The Mississippi Delusion Imagine a whole country going bankrupt over a swamp. France, 1719. People crushed each other to death just to buy paper shares. A hunchback made a fortune renting his back as a writing desk. Noble women faked carriage crashes to flirt with the founder for stock. The result? The paper became worthless. The entire nation collapsed. Slide 4: The South Sea Absurdity Paying millions for literally nothing. England, 1720. People invested heavily in a company whose purpose was completely secret. The pitch was literally an undertaking of great advantage, but nobody to know what it is. It raised a massive fortune in five hours. The founder fled the same afternoon. Greed blinds absolutely everyone. Slide 5: The Tulip Insanity Trading an entire estate for one single flower. Holland, 1634. A single tulip bulb cost more than a luxury mansion. One trader swapped tons of wheat, twelve fat sheep, four oxen, and a silver cup for just one bulb. A sailor ate a rare bulb thinking it was an onion and was thrown in prison. Then overnight, the bubble popped. Huge fortunes vanished into thin air. Slide 6: The Ultimate Takeaway History is a relentless loop of stupidity. Fake confidence turns into dangerous fanaticism. When your neighbors get rich quick, logic completely dies. Recognize the cycle. Survive the madness. Never become the exit liquidity of a greedy crowd.
