So yesterday I made a post asking for a different perspective on my skepticism of this view.
Although I got a lot of shit I wouldn't say the responses were all intellectual dishonest. In fact I'd say many like @PieceSeeker gave me some good arguments.
I basically concluded the following:
IQ alone cannot account for the amount of Jews in positions of power relative to the size of their population.
Other factors, such as tribalism, nepotism, and religious tradition exacerbate this.
Individual Jews should be judged as individuals, but it can't be denied that the ethnic/religious aspect of Judaism makes them more likely to fall in these patterns. This is very similar to Islamic communities who don't assimilate and soon create parallel legal systems for themselves.
Finally, the "conspiracy" isn't always a conscious one (with exceptions like WJC or AIPAC) but for reasons stated above, is still cabal like in nature based on the actions taken by the people involved.
Thanks for your responses, please post more if I missed anything.
