The bias blind spot is the cognitive bias of recognizing the impact of biases on the judgement of others, while failing to see the impact of biases on one's own judgement.〔Pronin, E., Lin, D., & Ross, L. (2002). ("The Bias Blind Spot: Perceptions Of Bias In Self Versus Others" ). ''Personality and Social Psychology Bulletin'', ''28''(3), 369-381.〕 The term was created by Emily Pronin, a social psychologist from Princeton University's Department of Psychology, with colleagues Daniel Lin and Lee Ross.〔(Emily Pronin, Center for Behavioral Decision Research )〕 The bias blind spot is named after the visual blind spot. Most people appear to exhibit the bias blind spot. In a sample of more than 600 residents of the United States, more than 85% believed they were less biased than the average American. Only one participant believed that he or she was more biased than the average American. People do vary with regard to the extent they commit the bias blind spot. It appears to be a stable individual difference that is measurable (for a scale, see Scopelliti, Morewedge, McCormick, Min, LeBrecht, & Kassam, 2015). ==Causes of bias blindness== The cognitive utilization of bias blind spots may be caused by a variety of other biases and self-deceptions.〔Antony, P. (2009). ("Unconscious bias and the limits of director independence" ). ''University of Illinois Law Review'', (1), 237-294.〕 Self-enhancement biases may play a role, in that people are motivated to view themselves in a positive light. Biases are generally seen as undesirable,〔Pronin, E. (2007).("Perception and misperception of bias In human judgment" ). ''Trends in Cognitive Sciences'', ''11''(1), 37-43.〕 so people tend to think of their own perceptions and judgments as being rational, accurate, and free of bias. The self-enhancement bias also applies when analyzing our own decisions, in that people are likely to think of themselves as better decision makers than others.〔 People also tend to believe they are aware of "how" and "why" they make their decisions, and therefore conclude that bias did not play a role. Many of our decisions are formed from biases and cognitive shortcuts, which are unconscious processes. By definition, people are unaware of unconscious processes, and therefore cannot see their influence in the decision making process.〔 When made aware of various biases acting on our perception, decisions, or judgments, research has shown that we are still unable to control them. This contributes to the bias blind spot in that even if one is told that they are biased, they are unable to alter their biased perception.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bias blind spot」の詳細全文を読む スポンサード リンク
