Of course chess players are smarter than everyone else

And I have a random article from the internet to support this claim.
Actually the article does provide references for this claim, as all good articles should. (I've read too many 'University studies have shown ...' articles to accept this kind of hand waving). But I am no expert in the field so am in no position to judge if these claims are any stronger than the 'ability and intelligence aren't linked' counter arguments. What I do know from my own experience is that memory and recall are important, as is the ability to draw objective conclusions. Whether these are traits of above average intelligence I do not know.
