Munger's Circle of Competence is a decision filter: figure out what you genuinely understand, refuse to play in arenas where others have aptitudes you lack, and concentrate your bets where your knowledge creates an edge. The rule is asymmetric — outside your circle, you're the sucker; inside it, you might find a mispriced bet worth a large wager.
