Earlier quoted context omitted.
There's a difference as it were between, roughly speaking, stored knowledge and being able to figure things out on the fly, but multi-factor analysis says there's only one factor for being good at IQ tests, oddly enough. And every test of doing mental tasks we know how to create correlates strongly with any other test. There's a good explanation about how the tests work here: https://www.youtube.com/watch?v=Nfg0hfrQM…
I'm not saying that the tests are useless, just that they should be renamed, and culture should look at them a little differently.
If we don't call one's skill at mental tasks 'intelligence', just how should we label it?
