>Bush's IQ score is estimated to be above 120, which suggests an intelligence in the top 10 per cent of the population. But this, surely, does not tell the whole story
Is there any evidence that his score is really 120?
Linda Gottfredson, co-director of the University of Delaware-Johns Hopkins Project for the Study of Intelligence and Society, told me:
"I recently converted Bush's SAT score to an IQ using the high school norms available for his age cohort. Educational Testing Service happened to have done a study of representative high school students within a year or so of when he took the test. I derived an IQ of 125, which is the 95th percentile."
