sorry to stop the circlejerk, but this is dumb. an intelligent person could learn to repair the car more easily and have more insight than a moron. intelligence exists and we all experience it everyday. the wais-r is a relatively good test, but no there is never going to be a perfect way to measure intelligence. you can say intelligence is just what the test measures which is really pretty non biased, but that’s reducing things too much. y’all know morons and people that are crazy fucking smart. experience in different subjects is distributed, but the ability to gain experience quickly is the biggest difference.
