Are Chess Players Actually Smarter Than the General Population?

Are grandmasters walking IQ machines, or just really good at patterns? The truth is more complex than the stereotype.

Yes, studies do show a link between chess skill and certain cognitive abilities—like memory, logic, and processing speed. But when scientists crunched the numbers, general intelligence (IQ) explained less than 1% of a player’s rating. In contrast, factors like how often someone studies chess or plays tournaments had far more impact (source: Burgoyne et al., 2016).

This leads to a key takeaway: being good at chess means you’re very skilled at chess, not necessarily a genius across the board.

Cognitive science backs that up. Legendary research by Adriaan de Groot showed grandmasters weren’t just “smarter”—they were better at recognizing board patterns. It’s a very specific kind of mental power (source: de Groot, 1946).

Real-life examples tell the same story. Some top players have struggled outside the 64 squares—financially, socially, even emotionally. Others, like Hikaru Nakamura, have thrived in multiple fields—from streaming to trading.

Bottom line: chess mastery reflects sharp, focused thinking, but that doesn’t automatically translate to other skills. Intelligence isn’t one-size-fits-all—and that’s what makes this question so interesting.
