I'm a bit suspicious of that sort of claim. You can go through a list of people who got Nobel prizes and investigate their ancestry and argue that lots of those people were "Jewish" but nobody does that sort of investigation on random members of the general population for a fair comparison. (And perhaps it would be impossible to do so: Nobel prize winners tend to come from social classes that have better records of their ancestry.) Also I've seen a huge range of values given for what proportion of the British population might be "Jewish", which shows the level of uncertainty involved. So the Nobel prize committee might not actually be racist ... :-)
