5 Group Bias: Attitudes that favor or disfavor a group; typically one favors one’s own groups.
Explicit Bias: known and intentionally used to guide judgment and behavior; measured directly. “My African American patients are uncooperative.” “My Latina patients complain endlessly.” “Thankfully I have a white patient now!” Implicit Bias: May not be consciously accepted, but may still influence judgment and behavior; measured indirectly.

14 Implicit Association Test (IAT)
Associations are estimated from speed of operation, instead of verbal statements. The IAT is the most well known and used measure of implicit associations (bias). It has the best demonstrated reliability & validity of currently available implicit measures. Can be used to measure many different types of bias and other associations:

16 Implicit Ethnic/Racial Attitudes of Primary Care Providers
Providers Community Black:White IAT Percentage of Sample Implicit race attitudes measured with an evaluative Black:White IAT N = 210, Experienced Internal and Family Medicine Adult Care Providers Mostly White (84%) Male and Female (53%) ***Range of responses, but shifted significantly to the pro-White side of the scale. ***No differences from a community sample Neutral Preference for African Americans Preference for Whites Blair et al. (2013). Am J Public Health.

17 Implicit Ethnic/Racial Attitudes of Primary Care Providers
Providers Community Latino:White IAT Percentage of Sample Same providers and very similar results, but with an evaluative Latino:White IAT Neutral Preference for Latinos Preference for Whites Blair et al. (2013). Am J Public Health.

18 Effects of Implicit Bias Are Increased When...
Behavior is less controllable Cognitive resources are low Time pressure or competing demands Low working-memory capacity Alcohol or similar substances Uncertainty and indecision Ambiguity of diagnostic information Lack of expertise Preference for intuition (affect) over cognition Match between bias and target characteristics Biased explicit attitudes or a lack of motivation to counter bias

19 How might implicit bias affect health care?
