R ace is a social construct, not a biological fact. Blacks get overdiagnosed with schizophrenia for reasons that have to do with racism, classism, poverty and the bias of the treater. There is nothing in the genome of the black person than renders them more vulnerable. The authors of articles on schizophrenia who avoid publishing data that point to race are being racist. The fact of the matter is that they have not figured out which of millions of variables account for the result they have found.
Race is an easy explanation.
