 These are all good points. I'm naturally sceptical about claims like the one in the article, because they hint at POV from the authors. It is not necessarily that there isn't a real effect, but whether the cause of that effect is what is implied. On top of the measuring bias possibilities mentioned by Slrubenstein, I would like to be sure they measured a control group of non-Ashkenazi Jews matched for education, income etc. These are factors which would explain changes over time, usefully tell people how to have high IQ, and generally not divide people based on race. It would also rule out many biases in the test. It would be interesting to know whether the improvements were genetic or caused by a cultural effect, like better work ethic. Perhaps I'm asking too much from one source, and I should just read that source ;-)   20:22
