Implicit Biases Predict Behavior in the Real World

Extensive research has documented the disturbing effects of implicit racial biases in a variety of realms ranging from classrooms to courtrooms to hospitals. Consider these examples:

A 2012 study used identical case vignettes to examine how pediatricians’ implicit racial attitudes affect treatment recommendations for four common pediatric conditions. Results indicated that as pediatricians’ pro-White implicit biases increased, they were more likely to prescribe painkillers for vignette patients who were White as opposed to Black. This is just one example of how understanding implicit racial biases may help explain differential health care treatment, even for youths.
Other research explored the connection between criminal sentencing and Afrocentric features bias, which refers to the generally negative judgments and beliefs that many people hold regarding individuals who possess Afrocentric features such as dark skin, a wide nose, and full lips. Researchers found that when controlling for numerous factors (e.g., seriousness of the primary offense, number of prior offenses, etc.), individuals with the most prominent Afrocentric features received longer sentences than their less Afrocentrically featured counterparts.
This phenomenon was observed intraracially in both their Black and White male inmate samples.
