He seems to pretty clearly acknowledge environmental factors exist, his claims only go so far as saying the example of black orphans raised by white families who typically have children with 100+ IQ only bridging less than 33% of the gap to go up to 89 suggests that genetics are a larger factor than evrionment between the two groups.

Or maybe, their IQ was always that high and their environment was keeping them from acting like it. The same way people here clearly aren't stupid, but they make arguments only a retard would.

The test isn't fucking magic. It can't read your mind. If you are barely sleeping or eating because of an extremely bad home, you aren't gonna accurately answer the test in a way to demonstrate your brain's ability proper.

He’s essentially claiming that genetics are the end all be all of IQ,

He makes no such claim in this video. Around 1:30 he says "IQ...is partly genetic in nature." I've never seen or read him make such claims elsewhere either. As I said in my other post, genetics is a very strong predictor of IQ, no more no less.

The variance in environment can raise iq by at least 10 points and in some cases 15-20.

I'm not familiar with any evidence of general population IQ jumps that large between the same genetic groups in different environments. The difference in American blacks IQ and sub-Saharan blacks is accounted for by the rather large European genetic admixture that blacks Americans have (that sub-Saharan blacks lack) combined with moderate increases that the Flynn Effect can cause in more industrialized nations, in other words blacks living in the US.
