GUCML makes one claim about chess, and it is a narrow one.
We do not claim that chess makes children smarter. We claim that competitive chess finds children who already are — earlier, more objectively and more publicly than any other instrument available to a nine-year-old.
This page lists the published work that claim rests on. It includes the studies that argue against the more popular version of the claim, because those studies are the strongest evidence in the field and they support our position rather than the popular one. Every source is linked to the original.
Chess is our filter, not our subject.
The evidence is real, the effect sizes are contested, and our work does not depend on winning the argument.
Chess instruction does not establish far transfer. Competitive chess does provide an objective, externally maintained, tamper-resistant performance history.
Early objective identification predicts long-term achievement. Chess is the filter. It is not the subject.
Nothing on this page asserts that participation in GUCML programmes improves cognitive ability, academic performance or mental health.
