Actually, there is not only good evidence for the environmental argument, Example: Environment has a profound effect on a person's mind (outlook, perceptions, attitudes, moods, etc.), and thereby has a significant, if indirect effect on that person's hormone production (quantity, balance). And believe it or not, in some (perhaps unusual) cases, unexpected changes in hormone production can happen later in life as well, not just during the "development" years. And I'm not talking about decreased
I am sorry if I sound rather harsh, but this is a typical example how real statistical research is replaced by politicized bullshit.
There is *no* more real research that the research I do myself, and know about myself: 1) I have generally tested in the top 1/000 of one percent of the population in "intelligence", and 2) I have expended considerable effort in personal study and experiments with what the human body is capable of under given circumstances. I have rubbed elbows with the world's most well-conditioned people (physically), for one, and have learned (for two) how to never get sick again (21 years running).
Dale, the "bullshit" I referred to was not yours, it was something that you mentioned, so do not take it personally. I read your messages with interest.
How to test a null hypothesis that differences in IQ between whites and blacks are at least partially a result of genetic differences and are not explained by "environment" solely?
I hope I didn't give the wrong impression - genetics are certainly a factor in anything human, however, environment has an overwhelming influence on subsequent development. It's not 100% to 0%, in other words.
Absolutely agree. Another problem in measuring "environment" is that it is rather hard to quantify.
All this "environment" stuff is rather easy to test and control for: take two groups of children -- one from one race, another from another race, who live in essentially the same conditions. Then compare the average IQs and check statistical validity of your samples. There was one study. They took a number of white adopted children and a number of black adopted children, and made sure that they controlled for other conditions such as adopted parents' income, etc. Guess what was the result of IQ tests of children?
I hope I don't regret saying this, but the above study has a far greater chance of being "politicized bullshit" than anything I'm likely to say, even when it's not from my personal experience. Get serious, Igor. How the devil are you going to evaluate the fairness, honesty, and other attributes of such a study? Do you know the researchers?
It is a good question. To me, the study can be done by the worst assholes on the Earth. As long as their data can be verified and their methodology is known, I have no problem with personal biases of researchers. - Igor.
