The first two linked articles are just criticisms of a Slate article attacking twin studies. The third is an abstract that points to a genetic link to heritability of intelligence. Out of curiosity, have you read the actual study itself and not just the abstract?
The first two linked articles were linked because of the studies referenced in the footnotes and the body of the posts. I linked them and cited the studies referenced in the articles.
Where have I said there are no differences between the races? Obviously there are. Height, build, hair and eye color etc. There are a wide variety of purely physical traits that are largely influenced by genetics, and some that are purely determined by it. I'm not black, so I don't know how I could "take it personally" when you assert black people are genetically determined to be generally stupider than white people, and attempt to draw larger conclusions from that.
You have not said there were no differences. Until now you have avoided admiting that there were. Thank you for clarifying that. Also, your characterizaion of "stupider" is unnecessarily inflamatory. By your formulation, whites are "stupider" than asians by just about the same amount as blacks are "stupider" than whites.
It is one indicator. I think you’re giving it undue weight. Significant outliers on either end of the intelligence curve are quite significant, although the very low end is far more so than the very high end. But there’s a huge swath in the middle where intelligence score has very little to do with performance in life. To compare it to purely physical characteristics (which you seem insistent on doing) for people who are so obese they can’t stand under their own power and people who are so emaciated their immune system is compromised due to lack of nutrition then weight is by far the most important characteristic of health. But for people who are a few lbs overweight or folks who are a little too skinny then there are other more important indicators.
It is the single most important indicator. In the study that I linked dealing with genomes, they found that the lowest possible amount that genetics (they linked two specific genes) plays in intellect was about 50%. Let me say that again, the LOWEST POSSIBLE AMOUNT OF ATTRIBUTION to intelligence from genetics is 50% according to that study.
I’ve addressed your questions. But I’ll also not ignore people drawing conclusions from the data that are not warranted. And I’m not going to so over correct from the PC folks who accuse everyone of racism that I’ll give a free pass to actual racist conclusions that result from misapplication of the data. The accusation of playing the race card (in a discussion of whether or not certain races are significantly stupider than others) is fairly ironic.
And now we've moved from "stupider" to "significantly stupider". I am pointing out studies and facts. Facts can be used for evil purposes. Just because some white skinhead can think that whites are the superior race (which, given that Asians tend to be more intelligent, I find that hilarious) from this research does not justify pretending it does not exist.
If you observe that genetics is one factor affecting intelligence I fully agree with that. If you observe that certain people groups tend towards one side or the other of the curve of intelligence I’d agree with that, although I’d argue that the influence of geography and inter-breeding between the people in that region are the actual influence there, not race per se. But since this discussion was started with the theme of success in school, I would argue that those factors are not relevant. People who fail to meet a certain threshold of intelligence are unable to succeed intellectually regardless of their culture or other factors. People over a certain threshold can succeed (to a point) regardless of other factors. Blacks may be X points lower on average, and a portion of that may be genetic. But to take that assertion and then go on to “And that’s why inner city areas and schools are so f***ed up, because those blacks are just too stupid to do well” is unjustified.
The difference between a person with a 105 IQ and a person with a 100 IQ is probably imperceptible. The difference between a group with an average IQ of 105 and a goup with a 100 IQ is rather significant.
Incidentally, the reason this is being discussed is because the article was comparing the results of very different countries. Rooster simply pointed out that the article ignored the genetic component and instead claimed it was all environment.
Further, inner city schools and children are not failing because blacks are stupid. The solution to that problem has absolutely nothing to do with the genetic issue we are discussing here. It has to do with horrible government, a terrible cutlure, and no accountability.
A person with a 95 IQ probably won't score as well as a person with a 100 IQ in his education. However, that doesn't mean that his education must be abandoned as a lost cause. He'll just likely get a lower C than the 100 IQ student (if our schools still graded as the scale was meant to be used.)
I've responded to this argument because too many people were denying the extreme importance of genetics, to the point of thinking that if it is true that 75% (to pick a number that is above the minimum of 50%) of intellect is due to genetics that is an argument for redistribution.
If you base your philosophy on falsehoods, it will come crashing down. The truth will always win out. (The gods of the copybook headings will not be ignored for long.)
