"It’s fashionable to say that intelligence isn’t real, or that we can’t define it, or that it’s a Western colonial construct. But the word points to a real thing: there is some quality which rocks don’t have, and which mice have a bit of, and which chimpanzees have more of, and humans have a lot of; and which is something like problem-solving ability or ability to achieve goals." We have IQ for measuring problem-solving ability, but it doesn't correlate well with the ability to achieve goals. That would be another very useful measure though, of something like intelligence * grit. Call it IGQ. An IGQ test would somehow set goals in a realistic, complex, chaotic environment, with social and physical as well as intellectual obstacles. So, a GPA is a sort of IGQ.
