This is the new midwit ceiling.
A 160 IQ is expected to occur in 1 in 31,560 people, which means if you have a 160 IQ, you're expected to be in an unremarkable group of around 250,000 on the planet.
It's depressing, I know, but this region of the long tail isn't going to get you any tail. If you're 160 IQ or lower, you don't necessarily have to become a sanitation engineer, but math, physics, and whatnot oughtn't be the direction you're going in right now.
