Israelis, Americans, or anyone else, are free to think they are 'the master race' - but that doesn't make it fact.
I have friends who are Jewish, but I never hear them say anything like that - I guess that's because those people are intelligent.
One of the guys leading the charge on neuroscience, the relevance of IQ, and the heritability of IQ is Stephen Pinker. Steve Sailer pointed out how it is rather ironic that he is a wispy and borderline effete Jewish academic -- and this is probably the only reason that he is getting away with it.
He co-signed a paper that dealt specifically with the linking of Tay-Sachs disease and other neurological issues to the rapid evolution of Ashkenazi intelligence.
Wikipedia has an article on this topic where you would find some good information.
I think the reason that your Jewish friends say nothing about this is because it tends to be a socially frowned on topic, and very few people are even willing to have the conversation. Moreover, what amount of people even talk about this stuff?
