Dear Ben,

Have you read "The Bell Curve"? I didn't, but this only because I can't buy it. Nevertheless I made a little research of my own about the book and the controversy that the infamous "Chapter 13" raised. All bullshit aside, I concluded that most researchers support the assumptions of the book and the findings, although these conclusions are not politically correct, or for that matter safe for the researchers to express.

I agree that most IQ tests are culturally biased, but I (and the book) am speaking about really scientific studies in which IQ test results were compared for identical twins, adopted brothers, etc., tests that were meant to minimize cultural impact, economical status differences, racial bias and others.

I am sure that there are many influencing factors that can alter the specific values of studies, but this is no reason to dismiss the science.

You shouldn't understand from this that I am a racist. There's nothing further from the truth. But I feel that people try too much not to see differences, which is maybe the "safe side" approach. This is ok as long as they don't become stupid or blind. There's nothing sadder than lying to yourself.
