I agree that intelligence is not needed to make useful contributions. However...
It’s damaging to repeat this though, since most bright people who are 1 in 10,000+ think they are 1 in 10 due to Dunning-Kruger effects.
I doubt this. Standardized tests are common (tests for CTY, SATs, etc.), and usually include percentiles. If you see “99.9+%” enough times, you’ll notice. And 1 in 10,000 is a lot. (400 college friends) × (5% of people smart enough to go to your college) = not enough people for a 1 in 10,000 person to know anyone brighter than they are.
