There's a strange comfort in knowing that your portfolio, your body, and the universe itself are all governed by the same invisible logic: reversion to the mean. In finance, this is the well-documented tendency of extreme returns to drift back toward average — a principle so reliable that Kahneman named it one of our most persistent cognitive blind spots, because we keep attributing the drift to our own decisions rather than to statistical gravity. What's less discussed is that evolutionary biologist Stephen Jay Gould observed the exact same phenomenon in biology — when he was diagnosed with cancer, he famously studied survival curves and realized that 'median' is not 'fate,' that the distribution around any average contains enormous individual variance. The practical gift here is double-edged: when things feel catastrophically bad (a losing streak, a failed experiment, a difficult season), the universe has a structural bias toward normalizing — but the mistake is assuming that *you* caused the return, rather than the system correcting itself. Today, notice one place where you're taking credit — or blame — for what is simply regression.

In which area of your life are you most likely to confuse a system naturally correcting itself with evidence that your actions are working — and what would change if you held that distinction clearly?
