My lede:

White physicians, like white lawyers and white people with doctoral degrees, are not immune from an implicit preference for white people over black people, according to a study in the August Journal of Health Care for the Poor and Underserved.

Psychological testing shows that doctors do not differ from the general population or from other highly educated people in unconscious racial bias, the study said. But critics doubt whether these test results are associated with unequal treatment of black patients. Other research, including a new study of patients with breast or colon cancer, has concluded that disparities are driven not by racial bias, but by differences in where patients get medical care.

The whole shebang.
