A new study says U.S. blacks get inferior care for cancer and a variety of other ailments compared to whites, however it's too early to know if there's a direct link between the findings and the quality of care delivered to blacks in the United States. 2,500 doctors were asked to answer subtle questions to look for subconscious signs of bias. They were also asked to quickly say whether photos of blacks and whites were positive or negative. Doctors in all racial and ethnic groups showed an implicit preference for whites versus blacks except for black doctors, who did not favor either group. "We don't call what these tests show prejudice. We talk about it as hidden bias or unconscious bias, something that most people are unaware they even possess," said Anthony Greenwald of the University of Washington, who created the test and helped with the study. The findings will be presented at the American Public Health Association's annual meeting in San Diego.
