I’d never given much thought about how IQ tests had been designed. Turns out they settled on the bell curve they wanted, and just arbitrarily changed the questions until the results conformed to it — that’s how scientific these tests are.

Here’s an interesting fact: in the first version of the Stanford-Binet IQ test, women on average did better than men. Since women could not be more intelligent than men, they removed questions women did better on, and replaced them with ones men did better on, until the results came out right.
