satranç yeteneği ve iq ilişkisi jlevitt durcan

Back in 1988, there was an impressive chess festival in the small industrial town of Saint John, Canada. Two large and very strong Open tournaments were combined with the complete set of seven Candidates’ matches in the World Championship cycle of the time (Karpov was to join the seven winners). The English contingent were all on good terms and in good cheer (Nigel Short was making mincemeat of Sax in his match, likewise Jon Speelman of Seirawan) and usually formed, combined with certain selected ‘foreigners’ (like Spassky), a massive eating party which the local restaurants struggled to accommodate. I have a fair recall of the conversation on one such evening. Nigel Short was asked what he thought his IQ was. He was not sure, but (far too modestly) proposed 130 or 140. John Nunn, his second, suggested that with a little training, Nigel could knock his score up to at least 160. Speelman was not impressed by IQ tests generally, and everybody saw the inadequacy of any test which depended on how much practice you had had at the type of questions involved.
At this point, some bright spark (me) suggested that it might be a better measure of intelligence to do two tests and see how much the person improved. Quick as a flash, Nigel replied that this was a very bad idea since you could do deliberately badly in the first test! It took me a few seconds to grasp his meaning - that you could artificially inflate the difference in your scores and thus score better in the proposed test.
