Paradox of Skill

The paradox of skill is Michael Mauboussin’s thesis that as everyone in a field gets better, luck plays a larger role in outcomes. When the absolute level of skill rises and the spread between competitors narrows, differences in results increasingly come down to chance rather than ability — so improving skill across the board can paradoxically make outcomes look more luck-driven. The framing comes from Mauboussin’s book The Success Equation: Untangling Skill and Luck in Business, Sports, and Investing.

In Kyle’s notes it underwrites the broader Skill vs. Luck analysis Mauboussin supplies for the “what is an investor” question: placing any activity on a continuum from pure skill / no luck to no skill / pure luck, and the related move of finding performance measures that reflect skill rather than outcome (Process Over Outcome). The paradox is why outcome alone is a poor judge of investing ability in highly competitive markets — and why Kyle uses Mauboussin to argue that strategy and outcomes shouldn’t be conflated.

Context: The “paradox of skill” was popularized by Mauboussin and is often illustrated with sport (e.g., the disappearance of the .400 hitter in baseball as overall play improved) — when skill becomes uniformly high, the variance in results is dominated by luck.
