Individuals are often susceptible to bias in their given fields; however, they may not acknowledge nor be aware of this phenomenon. Moreover, people typically can recognize bias in others yet fail to realize that they themselves are susceptible to their own bias. This is referred to as the bias blind spot, an unconscious meta-cognitive bias. Unconscious bias can lead to impaired decisions and can cause problems in the field, especially if professionals are defensive about bias mitigation procedures if they see them as unnecessary and threatening. The purpose of this thesis is to analyze and examine the perceptions that professional forensic psychologists have about bias in themselves and bias in their colleagues. Eighty-four professional forensic psychologists were surveyed and asked about their perception of bias in themselves, their colleagues, an average adult, and experts in another domain: forensic science. For this study, these forensic psychologists were asked to predict the bias that they themselves might have in their judgment, that forensic scientists might have in their judgment, and that the average adult would have. As hypothesized, and consistent with the bias blind spot, professional forensic psychologists rated their peers in the same field as having a higher amount of bias in their decisions than they themselves. Moreover, they also rated other professionals in similar fields (forensic science) as having a higher bias rate than themselves. In addition, participants rated bias mitigating procedures as being a higher threat to their field than a different domain (i.e., forensic science) – consistent with hypotheses. These results suggest that professional forensic psychologists are susceptible to the bias blind spot and its consequences.
