I’d be amazed if that sort of thing wasn’t happening, but you see the same sort of effect on all sorts of things which correlate, like spelling and grammar and success in studying.
Presumably the hope with IQ tests would be that the amount of training you’d need to do to top out would be low compared to, say, learning English spelling. Allowing you to get a reliable, but not terribly costly, indicator of how good you’d become at all the other things with practice.
