Confirmation Bias: A Ubiquitous Phenomenon in Many Guises

Dr. Raymond S. Nickerson of Tufts University provides a detailed analysis of the way that confirmation bias is manifested in a variety of practical contexts.

Abstract: Confirmation bias, as the term is typically used in the psychological literature, connotes the seeking or interpreting of evidence in ways that are partial to existing beliefs, expectations, or a hypothesis in hand. The author reviews evidence of such a bias in a variety of guises and gives examples of its operation in several practical contexts. Possible explanations are considered, and the question of its utility or disutility is discussed.
