We are prone to overestimate how much we understand… and it’s a mental trap that costs us daily. This insight from Daniel Kahneman exposes a fundamental bug in our human software, making us blind to luck and overconfident in our own skill. Once you see this pattern, you can’t unsee it, and it changes how you make every decision.

Meaning
At its core, this quote is about two critical errors: our inflated sense of understanding and our blind spot for randomness. We think we know why things happen, but we’re often just crafting a story after the fact.
Explanation
Okay, so here’s the thing. Our brains are wired for coherence, not accuracy. We have this deep, almost biological need for a story that makes sense. So when an event happens—a startup succeeds, a stock market crashes, a pandemic unfolds—our brain instantly weaves a neat, causal narrative. “They succeeded because of their brilliant, disruptive idea.” We rarely stop to consider the thousand other startups with brilliant ideas that just… got unlucky.
We attribute way too much to skill and planning and far too little to the roll of the dice. It’s why a fund manager who beats the market for two years gets hailed as a genius, when statistically, someone *has* to win by pure chance. We see skill where there’s often just luck. And that overconfidence? It’s dangerous. It leads to bigger risks, failed projects, and an inability to learn from actual mistakes because we’re so busy congratulating ourselves on our supposed brilliance.
