Shit, it's such an amazing evolutionary trait that its bearers will soon disappear. Why are we then obsessing about it? Or following the IQ-cult's logic, should we be saying "Oh dear, according to standardized tests developed by a random psychologist 70 years ago, Koreans have a mean national IQ 7 points higher than us so they should be ruling the world"?
Never seen anybody say the guys with the higher IQ should be "ruling the world", at least, not unless I go back to Kipling.
There's not a lot of White-Man's-Burden style imperialists left these days.
What national/racial IQ is, is a useful counterargument to the idea that if we let infinite amounts of South Americans in, we're going to get a shiny multicultural techno-utopia. Instead, we're gonna get Brazil without the hot chicks, and SJWs instead of carnivale. A nation of Brazilian-style favelas, except instead of big-booty chicks with loose morals you have scowling obese SJWs lording over you, is something I want to avoid, so I'm glad to have this counterargument available.
It's also a useful counterargument to the idea that American blacks perform more poorly than whites in aggregate, despite the fact that we've been trying every advantage we can think of for something like 40-50 years now, because of invisible "systemic racism". I'd rather not lose out on say, a promotion or a job, to a less-qualified black candidate in the name of affirmative action, so I'm glad to have this counterargument available. (Not that I could possibly share it with my boss without getting fired, but hey, it's good that it's out there.)
On a smaller level, IQ tests are a great way of figuring out things like who should go in the advanced track at school. I'm not sure if they have this where you're at, hell, I'm not sure they have it where I am anymore, but back when I was in school they had a gifted class for like 6-10 students who would be given advanced schooling. Called it a "gifted program", if I remember right. All students took a test to determine their IQ, and the ones who scored particularly high were sent to the class. I got in, and I benefited from it a lot. My grades were pretty shit, so if they'd just picked the 10 students with the highest GPA I would've been passed over. So that was, at least from my perspective, a pretty good use of knowing somebody's IQ.
It's good for lots of stuff like that.
