Cognitive Bias – Part 1: What they are. What they do.
Cognitive bias is a term that refers to the ways in which the human mind is inclined to process information in ways that may lead to inaccurate or distorted outcomes (Haselton, Nettle & Andrews, 2005). These biases represent systematic patterns of deviation from norm or rationality in judgment and thus can lead to inaccurate perceptions, illogical conclusions, and even irrational behavior when individuals rely on their own constructed reality rather than the objective reality (Ariely, 2008; Baron, 2007). In other words, an individual’s thoughts and/or behaviors might be determined more by how they create reality, than by the unbiased input.
