Investors don't lose to the market, they lose to their brains.
When the market surges, the system urges you to "wait a bit longer," and when it crashes, it forces you to "cut losses quickly"—by the time your rational system is ready, emotions have already hit the button. Kahneman's prospect theory proved it long ago: the pain of losing 1 unit requires earning 2.5 units to recover. This loss aversion makes you cling desperately to losing positions while rushing to sell winning ones. The most ironic part is "sell when break-even": the cost line is not logic, it's a psychological prison. The moment the price rebounds to your entry point, the sense of relief instantly crushes all rational planning. Emotion is autopilot, rationality is manual transmission. The market never harvests intelligence—it harvests human nature.
