We may need to be more explicit about the claim under discussion. I intended to say that if you partitioned students by race and economic status, ran a regression, then also added in some gene markers and ran another regression, you would find the race coefficient decreased more than the economic status coefficient.
Oh. That makes sense then, though there's the question of whether you've picked the relevant genetic markers.
I want to learn what's well-understood about education. I expect to launch myself into some endeavors in teaching the first few levels of epistemic and instrumental rationality - ie., critical thinking and problem solving. I'm a little suspicious, though, of the scattered educational texts that I've so far read. In particular, education seems like a field where it's easy to have motivated thoughts, and hard to gather good data.
With my background (Math and CS) I'm a little at sea in educational literature. Does anyone know of good, reductionist-grade or evidential-grade, introductory texts in education?
