Big 4

Keep in mind, it isn't like I haven't asked them to explain it clearly. But the most they give me are some criticisms of things like twin studies which stop like nobody from making claims with them. Because these studies do try to internally validate their resilts or control for issues.

1. Heritability isnt real. Not imperfect right now but not real. And the sources they use don't even get the definition of heritability right. They dont grasp it is measuring the proportion of phenotypic variation caused by genotypic variation so they say GxE means you can't parse how much is genetic and what isn't. Which is weird, basically saying "you cant know so you cant ever be right but I am"

2. Iq isn't real because it is forced to fit a curve and is biased against low ses people. And doesn't predic job performance for not demanding jobs. Just that all achievement tests are based on it, even progressive matrices and baylee scales somehow. Iq is just the most studied mental trait.  What matters is if we can show it is a mental trait which races differ on for genetic reasons, it will hardly be the only trait which differs. And that iq matters for how well you will do in our economies. That kills the oppression narrative

3. Epigenetics, canalization, etc

4. Find the genes, protein analysis, kmockout. Oh it is a bit underpowered. Then it isn't real! And biplog is disproving it! Yea, GWAS is only giving like 4%, but it gives low results for height too. By you only care about iq so you say it destroy iq and heritability.

No proof of environmental determinism. A constant demand for more than a concept ever stated it could prove. unreasonable and lopsuded standards of proof. And ken richardsom and dennis noble

Basically, because it is hard to extricate sign aspects of this organic system (they say) then the idea that genotypic variation accounts for variation in iQ among groups is automatically wrong because you "can never know"

And a prevailing theme of "ducking scientists are lying and making me pissed. Richardson and Noble do this. My favorite example of Richardson citing Deary saying we don't know what intelligence is exactly and then getting mad he is favourable toward GCTA
