Bias is a reality of the human spirit. We exhibit bias in many ways, such as when personal experience works to our advantage and helps us make a correct decision or choice. Bias can also result in flawed evaluations, which may contribute to errors of reasoning and undesired performance outcomes. Self-evaluation bias, sometimes called “myside bias” (Stanovich, 2009), is the tendency to believe that your way of thinking and reasoning is superior to the methods used by someone else in an identical or highly similar situation. Perhaps the best example of self-evaluation bias is the highway dilemma.
