I think there is a positive correlation between chess ability and intelligence, but being a world-class chess player doesn't indicate having "world-class intelligence". The problem is that the null hypothesis was that Polgar sisters will be highly intelligent, because their parents were highly intelligent. But we don't have indications that they would excel in any other intellectual field apart from chess.

> being a world-class chess player doesn't indicate having "world-class intelligence". I agree, but if chess ability does have a positive correlation with intelligence, isn’t that enough “proof”, as intelligence itself allows for “excelling in other intellectual fields”?
