Twin studies show that genetics accounts for 97% of variability in fingerprints (duh!); 70% of IQ, 50% of sexual behavior, 50% of criminal activity and 40% of social attitudes.

Those same twin studies "prove" a genetic link to homosexuality. I question the twin studies that indicate such things, because the famous ones are based on severely flawed models.

Average IQ level of blacks is 15 points lower than whites.

The Stanford-Binet test does presuppose some cultural knowledge. Once you correct for socioeconomic factors, that 15-point gap vanishes to within the MOE.

Average testosterone levels are 10-20% higher in college-age black males than whites.

What was the sample pool for this study? How many blacks versus whites in college are "juicing up" with steroids to compete in sports?

IQ and testosterone levels are key ingredients in behavior among young males.

True enough. However, what factors outside of genetics influence these ingredients?

"The Stanford-Binet test does presuppose some cultural knowledge. Once you correct for socioeconomic factors, that 15-point gap vanishes to within the MOE."

I think the 15-point gap is pretty consistent over all the common IQ tests.

Oh, horsesh*t. What is your source for that?

The racial grievance industry has spent the past fifty years trying to validate this "cultural bias" crap about academic testing, even to the point of being allowed to write the damn things themselves. And the differences not only never disappear, they don't even narrow!

So because you don't like the results of one genetic study you will throw out the results of them all? Were you an OJ Simpson juror by chance?

MANY different studies have studied identical twins (monozygotic) raised apart and found a 0.70 correlation for intelligence. This is enormous.

Look up the Minnesota transracial adoption study. They found that the average IQ of black babies adopted by white couples was around 85, the average IQ of half black babies adopted by white couples was 95, and the average IQ of white babies adopted by white couples was 105.

In "The Bell Curve", the authors note that the average SAT for Blacks from upper-middle-class families are lower than the SAT for low-income whites

Also, given that IQ has a lot to do with the income level you wind up with, correcting for parental socioeconomic level also corrects for parental IQ.

No they don’t.

On blacks having up to 20% higher testosterone levels in college: I wonder how many of this pool of blacks are in college due to the soul...er..sole fact that they were recruited into sports? This might prove a sociological difference and possibly not a genetic difference. Also...did anyone read the Bell Curve? It was very fascinating. But, in the end, we are all made in the image of God regardless of whether this issue comes down to socialization, environment, genetics or some combo.
