Yes, the BMJ is peer-reviewed, but so what? JAMA and the New England Journal of Medicine have published plenty of absolute crapola, and they are certainly peer-reviewed. Check out anything these two distinguised publications have ever published on gun control.

Political agendas rear their ugly heads under any circumstances, and biomedical researchers and publications are actually pretty bad on that account.

I see your point. One of the sad things about this particular "study" is the finding that the "Incidence of schizophrenia among Afro-Caribbeans and Africans in their own countries was much lower" may actually have medical significance. People of all ethnic groups suffer from schizophrenia. It's possible that new, more effective, treatment could be discovered through legitimate scientific inquiry. For instance, is the rate of schizophrenia lower among all ethnic groups in Africa and the Carribean, or only among the black population? This study doesn't tell us.
