I have met theoretical physicists who claimed that any human could understand superstring theory and quantum mechanics if only he or she was given the right educational opportunities. Of course, such scientists talk only with other physicists with IQs above 140, and seem to forget that their janitors, barbers, and car mechanics are in fact real humans too, so they can rest comfortably in the envy-deflecting delusion that there are no significant differences in general intelligence. (…)
The anti-intelligence dogma has not deterred liberal elites from sulking and ranting about the embarrassing stupidity of certain politicians, the inhumanity of inflicting capital punishment on murderers with subnormal IQs, or the IQ-harming effects of lead paint or prenatal alcoholism. Whenever policy issues are important enough, we turn to the concept of general intelligence as a crucial explanatory variable or measure of cognitive health, despite our Gould-tutored discomfort with the idea.
