Why is there heritable variation in human intelligence? If evolution favored higher intelligence, why aren't we all geniuses already? We proposed a theory in 2007, and now it looks like maybe it's right, given new genetic data. @LarsPenkehttps://twitter.com/LarsPenke/status/1168538003419095040 …
PS the Penke, Denissen, & Miller (2007) paper is here: https://www.primalpoly.com/s/2007-genetics-personality.pdf … ; all of my other publications about the evolution of intelligence are here, under the 'Intelligence' heading halfway down:https://www.primalpoly.com/all-publications-by-topic …

Was that orginal to you and your co-authors?
Evolution Doesn't favour higher intelligence. Just sayin
Tell that to all the animals with less intelligence than humans that went EXTINCT due to humans taking over the globe ... due to their higher intelligence.
Is that another way to say we have hit a ceiling?
Mutation explains variation but says nothing about the reason we're not all geniuses -- that requires stabilizing selection, as for example created by limits on pelvis size.
I read that the IQ is increasing though, even through the 20th century (after the nutrition and disease are not an issue in the first world). So maybe it's still selected. Perhaps high IQ people tend to have less children.
Because smart people are not selective enough about who they sleep with.
Maybe we are all geniuses but the bar isn't all that high. Or maybe the stupid people keep outbreeding the smart ones.
You are right, compared to all other animals, almost all humans are geniuses.
