Thanks Anthony for the comment! Black kids get lower education than White kids from the beginning. Parental education (SES) is a predictor of IQ, and Black kids have lower parental education (SES). All these suggest the Black - White differences are not genuine or biologically based, but only social, due to structural racism which still exists in the U.S. We should be careful not saying they are biologically different in a racially aware country that makes their life and survival very hard.

A very good point. I have two answers for the argument about the schizophrenia. First, schizophrenia is mostly a biological disorder, rather than social, so I would not expect less schizophrenia among Blacks, because my theory of higher resilience of Blacks is a social / learned thing, due to repeated exposure and enhanced coping. Second, some of the disparity in schizophrenia is due to misclassification bias, that White physicians tend to over-diagnose schizophrenia and under diagnose schizoaffective bipolar (still a mood disorder). A big literature there.... 

I like discussion, thanks for your thoughts.

That is very accurate but it is about African Caribbeans in U.K based studies, not African Americans. My research is on African Americans. The literature is very different in U.S.

From another point of view, the  North American Blacks do not have much of history of pride to lose it, or get anxious about it, and their daily life has less oscillations, in general; because they have their own way of life style & tone of activities. On the other hand, the North american blond-whites are in anxiety of being minority; some provinces have the job privileges to bilingual Spanish-English individuals. Also, the number of Hindu and Asian population are going higher, in which has a direct effect on the status of white group. Finally, the inter-relations and marriages between white and others are in record breaking level, comparatively, now. As a result,the  vulnerability of the white-ethnics would be higher now.     

Hi Faranack! Very interesting and compelling explanations. Loved them. May help me explain my findings. Do you also have some citations for these arguments. For instance, are there scientific papers or reports on 1)  daily life and pride among Blacks, 2) a rise in perceived threat among Whites about becoming minority, and 3) perceived concerns about status decline of Whites due to Hindus and Asians.

Thanks Anthony, very helpful! Please let me know if you found anything new.

I disagree that schizophrenia and indeed other mental illnesses are biological.  I would argue that they are minimally psychosocial and the conditions that manifest are simply the ability or inability of people to cope with the stressors that come with everyday living.

Thanks Anthony and Emeka for your response.
