Why Can't Fortune Tellers Beat the Stock Market?
1. If they can see the future, why are they charging fees?
A fortune teller who can see the future wouldn't even need to predict tomorrow's stock prices. Just guessing a little more often than others whether the market will go up or down, or which industry will take off, would give them a huge investment edge. A small edge, repeated for a long time, compounds.
So if they had that ability, why spend all day collecting fees for readings? Here's the real question: why doesn't the ability to see the future show up as repeatable results in financial markets? "A big change is coming" can be reinterpreted any way you like later. But an account's returns stay on record as numbers.
2. Experts and even cats: a few hits are not proof
Psychologist Philip Tetlock collected predictions from 284 experts over about 20 years. On average, their accuracy was sometimes worse than a simple rule like "current trends will continue." Being more famous didn't make an expert more accurate. There were consistently good "superforecasters," but all they did was update their probabilities when new information came in, keep track of their mistakes and avoid overconfidence.
The 2012 investment contest run by Britain's Observer newspaper is interesting too. Stocks chosen at random by Orlando the cat earned about 10.8 percent in a year. The professionals earned about 3.5 percent. That doesn't mean cats are better investors. It means you shouldn't believe someone has special powers just because they got a few things right over a short period. With enough fortune tellers, someone will get several in a row right by chance, and people remember only the predictions that came true.
3. The stock market is a giant public laboratory
The testing method is simple. Before the results come in, write down the prediction, the time frame and the criteria, and repeat this for a long time. If someone consistently beats chance and beats the market even after costs, then it's worth taking a second look. Without that evidence, there's no reason to believe in "the power to see the future" based on a few amazing hits. Before it's a place for fortune tellers to make money, the stock market is a public laboratory for testing the claim "I can see the future."
Conclusion: fortune telling and past-life regression are the same brain's fiction
During the impeachment of former South Korean president Yoon Suk Yeol, a survey of 100 fortune tellers reportedly found a hit rate of 18 percent. That's lower than the odds of guessing a yes-or-no question at random.
Past-life regression is the brain being led along by suggestions like "Close your eyes and go back into the past." A prophet is someone who falls into that state on their own. The scenes that come up are often from historical dramas, news or YouTube videos they once watched. Because of cryptomnesia, the brain forgets where the information came from and mistakes it for revelation.
The brain can't stand "not knowing." So it fills the blank called the future with a plausible story, a process called confabulation, and false certainty is born. Then if even one thing comes true, vague lines like "a benefactor will come from the east" get forced to fit the result. When the temporal lobe is stimulated, time and space can seem to warp and people can feel spiritual presences. This isn't a matter of faith. It's the brain misfiring.
