I have never been any good at IQ tests, so it may be that I find myself in the 16% of the population that Boris seeks to have dismissed to the outer darkness. But what I remember of the conclusions of the controversy stirred up by Eysenck and his followers decades ago was that IQ test scores demonstrated little more than ability at doing IQ tests. And even if there were a reliable measurement of intelligence (whatever you interpret intelligence to be), it is no more legitimate to dismiss or mock those of us with less of it than it would be to dismiss or mock those of us with lesser physical abilities.
To put it another way, would you consider Boris to be sensible? Or wise? Or well-balanced? Or generous? Or exhibiting any kind of empathy for his fellow human beings?
