Before completing the IAT section of the study, 60.5% of physicians agreed or strongly agreed with the statement: “Subconscious biases about patients based on their race may affect the way I make decisions about their care without my realizing it.” When shown the same statement after taking the IATs, 71.6% of physicians agreed or strongly agreed with this statement (difference in mean 5-point score = 0.33, P < .001 by paired t test). Meanwhile 74.8% felt that taking IATs is a worthwhile experience for physicians, and 76.1% felt that learning more about unconscious biases could improve their care of patients.
