Why the Discrimination Against IQ Research?

Studying IQ has a notoriously bad reputation in the academy and beyond. Why are many people hostile to research on intelligence and IQ?

The answer: social desirability bias. So says Bryan Caplan:

When lies sound better than truth, people tend to lie. That’s Social Desirability Bias for you. Take the truth, “Half the population is below the 50th percentile of intelligence.” It’s unequivocally true – and sounds awful. Nice people don’t call others stupid – even privately. … hostility to intelligence research is all out of proportion to its flaws – and Social Desirability Bias is the best explanation. Intelligence research tells the world what it doesn’t want to hear. It says what people aren’t supposed to say.
