Cheski, that article you cite is stating that a higher intelligence is non-existent, meaning that the rumor was surreptitiously propogated by self-conscious jews who wanted a better image for themselves, similarly to the practice of circumcision.
Following your religion is not going to increase your intelligence, cheski. Religiosity is the meaningless factor here. The difference is cultural, not religious. The jews who brought their children directly from Europe and made their homes on Grand Concourse Ave, NY made it a priority in life to ardently aspire to seek higher education because of their belief that while money could be stripped from you, money-making capacity could not be.
You are not a part of that, and neither are any of the jewish kids today. Expressing a forced belief in your religion because you think it will make you intelligent won't change that.
well i like all people regardless of their backgrounds because i look at the individual. That said, there are cultures that buckle down and put their nose to the grindstone. Take tour Asian (chinese, Korean etc.) you tend to see those kids with there noses in the books and they arent too concerend with having fun.
