Then what exactly do you think you are doing when you rant about how they didn't control for it?
> Your suggestion - with this fringe talk about "the sociologist's fallacy - is to eliminate any explanation from any study which does not assign success to invariant psychological metrics.
Nothing fringe about it, I'm afraid. This is well-understood in the statistics fields like causality you seem so loathe to actually learn about.
The point is: when you control for something and then go on to make causal claims, you are not making a minor tweak. You are assuming an extremely implausible causal model and making strong inferences from there about what are real causes and what are not. You have entirely failed to argue for a causal model which would justify simply controlling away family background etc, and it seems from how your comments handwave it away in favor of nothingburgers, you don't even understand what you're arguing for.
