Doctors’ unconscious biases favor whites but do not affect high blood pressure treatment for their minority patients, according to a Â鶹ӰԺ study, even though a previous study by the same research group found that doctors’ biases are reflected in lower ratings by African-American patients. The new research, led by Irene Blair, an associate professor in CU-Â鶹ӰԺ’s Department of Psychology and Neuroscience, is published in the Journal of General Internal Medicine.
