@[email protected] I think that was a large part of his point - he was writing in the 70s so that was reasonably radical and it's not like there aren't still a lot of misconceptions about 'giftedness' (such a terrible term, as you say). I've seen his work and the follow on work that built on it (Silverman etc) used to push back against the idea of the 'gifted genius', mature beyond their years, striding forwards with logical certainity because being intelligent obviously means 'being able to do more of the same thing overbody else can.'
