afaik it's not supposed to change with age or minimally

I don’t think it’s completely invalid.
As an experiment my whole class in high school was forced to do an IQ test.
Those who excelled at mathematics tended to get much higher scores than those who struggled with mathematics.
But yeh IQ fails to show others aspects and characteristics of one’s personality. There’s a lot of high iq people who are lazy and lot of low IQ people who are hardworking. So it’s a terrible predictor of where you end up in life.
I think it’s more just a good test of how individually efficiently you can solve problems.
yeah, that's my issue with it; it's used to measure something that it has little relationship with. It's largely used as a predictor of "success in life" and that is so far from what is being measured.
