RW always want to deny this for some reason and claim Jews cheat their way to success

Actually a large percentage of the right have supported the notion that Jews are intellectually superior, for various reasons. In fact my impression is that most right wingers start out with this view, but many of the more thoughtful and intelligent ones gradually change it once they look deeper into it.

Why do so many on the right embrace the notion of higher Jewish intelligence? For one it makes Jews seem more dangerous and scary and helps to explain their success in carrying out some of the conspiracies they've been accused of. Secondly, it helps bolster the argument that genes explain intelligence and behavior more than environment. Finally, among dedicated and pragmatic race realists who are worried about getting their message out, buttering up to Jews on the subject will help ensure the message gets out and shield them from attack(so long as Jews are placed at the top of the intelligence hierarchy).

which sounds like the type of copes non whites make for European success.

Not really. In the case of comparing whites to non whites, you are talking about many tens of thousands of years of divergent evolution in vastly different environments, in some cases possibly even hundreds of thousands of years. This is how natural selection gives rise to different traits, including cognitive abilities.

In addition to that, we now know that in some cases different human population groups not only had these tens of thousands of years of divergent evolution, but also bred with different archaic human species that themselves had even longer periods of divergent evolution. For instance DNA evidence shows that West Africans derive up to 20% of their DNA from an unidentified archaic human species whose DNA is not seen in any other human population, while Europeans and Asians derive up to 2% of their DNA from Neanderthals, an archaic human species of whose DNA is completely absent in most sub-saharan Africans. These recent discoveries only further bolster the possibility that different human populations could have dramatically different cognitive capabilities, and this is arguably what we see when looking at the technological and cultural achievements of these different population groups.

By contrast, when comparing Jews to Europeans, you are claiming a dramatic difference in cognitive abilities arising on a timescale of just hundreds of years, by people living in the same environment, owing exclusively to different cultural and religious emphasis, which somehow made one group intellectually superior, and that this was almost uniformly the case in every part of Europe this group scattered to, regardless of which Europeans this group derived most of their genes from, aka Slavs or Germanics or Southern Europeans. It doesn't really seem plausible, much less likely. Sure you could see SOME increases in SOME types of intelligence, but nothing as dramatic as one would see comparing groups that evolved separately for 200,000 years, and nothing that would give rise to global cognitive superiority, and nothing that would explain this group achieving little to nothing of note scientifically, technologically, or culturally until very recently. That's even BEFORE you look into comparing large and representative IQ scores, and look at what parts of these scores the groups you are comparing do well or poorly on(IE even in the limited and unrepresentative samples we have where Jews overall scored better, they still tended to do best on those segments of the test that are most influenced by environment, and poorest in those where environment clearly plays the least role). Once you look at actual large and representative samples, IE from Israel, Jews don't even appear to score ANY better, on ANYTHING.
