You are joking, aren't you?

Ben Wechsler IV: “Interesting. So, relative to whites, blacks are extremely high achievers, doing much more with what they've got than white people.”

No, because the first statement is in reference to background factors, not earned income. Controlling for IQ closes most of the B-W wage gap. So blacks and whites matched for IQ have similar occupational returns.

On the other hand, we see very different IQ outcomes for the children of blacks and whites of matched economic backgrounds. Black children from homes in the highest socioeconomic bracket have lower IQ scores than white children from homes in the lowest socioeconomic bracket. And their adult income reflects their IQ score virtually regardless of race or class background.

So this could be interpreted either as blacks underperfoming given initial socioeconomic advantages, or neither blacks or whites performing any differently than you would expect give initial IQ scores.

“Self-published?”

Figure 8 is the best piece of evidence offered on this question so far.

La Griffe is no piker, and the PISA numbers are all available to check online. Williams study isn't published until next month, so we can't evaluate it's methodology or know what data set was used. But it's hard to compete with the PISA data if we are asking how much cultural differences matter.

Not just expectations, actual barriers – actual barriers, says the woman who was told by her high school “guidance counselor” that she couldn't take Algebra II because 1 – “the class was full” and 2 – “she wouldn't want to be the only girl there.” This was in 1978, people! I went on to study conic sections from Apollonius (ancient Greek!).

Mwah-hah-hah. You won't be able to use entrenched social power to protect you from intellectual competition much longer, you heterogametes you.

But seriously, the power of testosterone in the womb to shape brains is amazing. Due to these effects, I will never be surprised if men on the far extreme of math ability continue to outnumber women at that extreme, just because of this factor.

Men and women are different in some ways. Vive la difference! That doesn't prevent us from establishing a just society, however.

Back to this dorky g factor. I just don't believe in it. No one can agree on how to describe this puppy, no one can agree how to measure it, no one can predict with it — it's just a unicorn, folks, give it up. What the hell is scientific about it?

Those stupid tests are completely biased in numerous ways, they just are. African-Americans are disadvantaged by them, while people of my ethnicity are favored by them. They should all be scrapped. If you believe otherwise, then you're stuck believing I'm a near-genius and the people of my ethnicity are on the whole the smartest people in the world. Which just ain't so. Prima facie, Nobel prizes or not.

Why are so many (guys) attached to this idea so strongly? Isn't that suspicious?

Especially when the most comprehensive and exhaustive research on the matter thus far strongly indicates this is not an argument “the side of the angels” is going to be winning. In fact, if this was a less politically sensitive subject, it's a safe bet that this would largely be considered a settled matter based on the evidence as it stands. But, considering the social and political implications, one suspects no evidence, no matter how conclusive, will ever be considered adequate in some quarters.

Interesting. So, relative to whites, blacks are extremely high achievers, doing much more with what they've got than white people. Black persons with IQ's of 84 earn what white's of average IQ earn, while retarded blacks earn what whites in the low average range earn. And blacks with merely average IQ's earn what white's with IQ's of 116 earn.

How do they do it? Maybe IQ isn't as robust predictor of success as it's made out to be by bloggerss.

My sense that people have preferences about what results they'd like to come out of this research comes almost completely from discussions outside of this post and blog.
