Implicit bias

Patients are faced with certain barriers when communicating with medical providers. Impicit bias is subconscious thinking toward certain social groups that can negatively influence a provider's assessment. 

Disparities in health care

Disparities in health care might be due to clinician bias (or prejudice) against patients from racially and ethnically minoritized groups and stereotypes about the behavior or health of patients in these groups. Although most clinicians report egalitarian beliefs, bias against racial minority and other socially disadvantaged groups is typically unconscious and reflects implicit, rather than explicit, attitudes.[1]

Dunning Kruger effect

Cognizance of bias might be painful and even suppress awareness of a behavior that needs modification. Sharing this "enlightenment" might be a way to approach self-improvement but  is probably inhibited as it makes one vulnerable. It is hard to turn competitive tendencies that helped us achieve so much into collaborative effort and engage others question themseleves. Or, perhaps the ones who question their own values aren't the ones who need it. The Dunning–Kruger effect is a cognitive bias whereby people with low ability, expertise, or experience regarding a type of task or area of knowledge tend to overestimate their ability or knowledge. Some researchers also include the opposite effect for high performers: their tendency to underestimate their skills. [2] The same might be true for what is not a "skill" but an attribute like being impervious to bias. Since it is implicit it is hard to see it.  

Could training overcome implicit bias? What are the Elements of Implicit Bias Training?  The evidence for the effectiveness of implicit bias training is nascent, and reducing biases and their effects is not a simple endeavor. Literature reviews suggest that many interventions have no effect or may even worsen implicit biases which, paradoxically, tends to occur when people are told to avoid stereotyping. Many programs use the Implicit Association Test (IAT) as a precursor to enhance understanding about how cognitive processes work and to promote self-awareness of learners’ own implicit biases. However, poorly guided use of the IAT may lead to greater interracial anxiety among individuals discovering their own biases for the first time or among those discounting IAT results because they do not match their explicit egalitarian values. Due to controversies in the existing evidence, current training programs vary in their learning objectives, content areas, frequency or length of training, and methods to achieve their stated objectives—and as a result, vary widely in their effectiveness. In addition to being wasteful, ineffective training may also be harmful if it gives learners and institutions a false sense of confidence in training that has had no benefit. [1]
