Are we Neanderthals?

All aspies should come together to unite a culture and a race of man, not by our skin colors, but by our intellectual gifts that we share together. A brother is a brother is a brother, reguardless of what color he might be. Or what region we are from, gender, etc.

OK, so lets keep the discussion on scientific bases instead then.



OK, once more.

1. Statistics of participation (basically all versions look like this) has a slight overweight of people that score higher on Aspie score than NT score.

2. We know that ASDs + AD/HD and other neurodiversity-conditions, which Aspie-quiz messures, have less than 1/10 the prevalence of NTs. IOW, people that do Aspie-quiz are strongly biased towards people that suspect they might be Aspies. Another way to look at this is to study the Aspie proportion on various NT sites. This proportion is between 10-20% on many NT sites. However, psychology-students from Norway, when asked to do the quiz, only have half the average Aspie score as NT control groups. IOW, it is a fair estimate that the general population have less than 10% Aspies. The AQ test comparision also supports this.

3. The African-American group in the US have similar scores as the Caucasian group. This means that the same thing (2) is operating in African-Americans as well (they are less likely to do the quiz if they are not suspected Aspies).

4. The number of African-Americans that answer the quiz is only 1/6 of what we would expect based on the racial composition of US.

5. Based on answers, the 1/6 participation of African-Americans is statistically significant at the 95% level.

6. As controls, both Asians and American Indians have the expected participation and average score distribution.

7. American Indians are also a disadvantaged group that might have lower participation for this reason, but they don't.

8. Internet usage statistics from major US surveys only indicate a small difference in Internet-usage between African Americans and Caucasians.

As for how to extrapolate from African-American prevalence African prevalence, this is a straight-forward operation. Input data:

African-American (AA) prevalence = Caucasian (C) prevalence / 6
AA genetic material = 9 / 10 * A (African) + 1 / 10 * C

A = (10 * AA - C) / 9

Assume that African prevalence can be estimated only by admixture (valid if ASDs are genetic):

A prevalence = (10 * C / 6 - C) / 9 = (4 / 6) / 9 * C = 2 / 27 * C (about 7% of the Caucasian prevalence)

If you have objections to the reasoning, please state these explicitly and referer to the exact problem. IOW, argue in a scientific manner if you are a PhD student and refrain from political correctness.

One should also note that the prevalence study in Aspie-quiz cannot discard the hypothesis that African ASD prevalence is actually nil. This would be the result if African American prevalence is 1/10 of the Cacausian, which is possible since the lower end of the 95% CI is 1.1%.

I certainly agree to that.

I don't "group" them. I used Asians and American Indians as controls for the validity of the concept.



It is very possible, but if that is the case it only supports my general proposition that culture to a large extent is based on DNA, and that Africans are the "outgroup".



I'm sure you are partly right that I don't know too much about African culture. I'd be willing (even eager) to study the differences if they were readily documented. Unfortunately, poltical correctness plays a role here, because cultural differences can easily start being interpreted in terms of genetic differences, which is a taboo.
