    Flowers, fortune, and FOMO

    When tulips first arrived in Holland from Turkey in the 1600s, they were unlike any flower Europeans had ever seen. Their vibrant colors and unique patterns made them a must-have luxury item. As demand grew, prices soared. Soon, people weren't just buying tulips to plant – they were trading bulbs like stocks. 

    Mackay discovered that at the height of this craze, a single rare bulb could sell for more than a grand house in Amsterdam. Merchants were trading their shops for tulips. Farmers were selling their land for bulbs.

    But then, in 1637, something changed. A few big buyers missed an auction. Suddenly, everyone realized these flowers might not be worth quite so much. Within days, prices crashed. People who had traded everything for tulips were left with nothing but pretty flowers worth a tiny fraction of what they had paid.

    Less than a century later, a similar mania gripped England. The South Sea Company claimed it would make a fortune trading with South America. It didn't matter that Spain controlled those trade routes, or that the company had no real business plan. The stock price kept climbing as more people bought in, hoping to get rich quick. Even brilliant scientists like Isaac Newton invested. When this bubble burst in 1720, thousands of families lost everything.

    These stories might sound bizarre, but similar patterns keep repeating. In the 1990s, people hoarded Beanie Babies, convinced the plush toys would fund their retirement. In 2008, house prices crashed after years of speculation. More recently, cryptocurrencies and NFTs have seen spectacular rises and falls.

    Mackay noticed something crucial about these manias. They all follow a predictable pattern where initial excitement turns into greed, then morphs into a kind of mass delusion. At first, a small group of insiders starts making genuine profits. Then stories of their success spread, pulling in more investors. As prices rise, these success stories seem to validate themselves, creating a cycle where good news drives more buying, which creates more good news.

    This is when the underlying psychology becomes evident. As more people get involved, the focus shifts from the actual value of the asset to stories about instant wealth. Nobody asks basic questions anymore, like what makes tulips or tech stocks or crypto actually valuable. Instead, conversations center on neighbors getting rich, colleagues quitting their jobs after making fortunes, or friends buying luxury cars from their profits. 

    The fear of missing out becomes so powerful that it drowns out the inner voice of caution. Even skeptics start to wonder if they're wrong, if they're the ones missing something obvious. This social pressure, combined with the apparent evidence that everyone else is getting rich, can overwhelm even the most logical minds. After all, if Isaac Newton himself could get caught up in the South Sea Bubble, anyone can fall for the next big thing.
