Umm, should we believe that the perhaps the most important attribute of homoSap is not under genetic selection? Everyone that has raised kids and seen their grandkids develop knows that intelligence is not equally granted to all. Everything that could be selected for (because there is a phenotypical difference) is by definition selected.
If you really want to get precise about it, what is being selected for is the capacity to have a given IQ in good environmental conditions. Obviously, there are environmental circumstances (e.g. lead exposure) that can prevent people from reaching their potential.
I am on the left. This doesn't mean that IQ isn't real. It may mean that at a large population level that environmental deprivation can impair people reaching their full potential intellectually. Indeed, there is solid evidence that, e.g., children who test as "gifted" at a young age underperform their potential when they grow up in very bad schools.
What are the odds that some historical alleles for intelligence are not well-represented in modern populations, and thus the estimates for Mesolithic foragers are low? There may also be newer mutations not present in them. I find it hard to believe that with their greater cranial capacities, all that additional material was or naught. Unless perhaps the modern, moderately high correlation between MRI-measured brain volume and intelligence is an artifact of current evolutionary trends.
Good schools are all the same, but each bad school is terrible in its own way. One of the girls, that spent so much time in our house that she refers to us as her parents, got a teaching degree and taught in a downtown Houston high school for five years. She wanted to make a difference for the children who didn't have access to the good schools. This small, petite blond was physically assaulted every year. The school administration/board did nothing as this was accepted as "that's just the way it is". So now she teaches in a rural/outer-suburban school where such behavior doesn't happen. What can a gifted child in a bad school do? Hope your parent move to a good school district I guess. (This is 20 years after the Texas school systems were reorganized to provide equivalent funding for all schools.)

you believe in iq from dna

"you believe in iq from dna" yes.

i thought you are on the left. the left knows iq disfavors certain races and is a tool for oppression
