Cognitive Bias

Human beings are processing information all of the time: in both a fast and automatic fashion, and as slow and effortful process (e.g., Kahneman, 2011). In the context of psychological therapy the term cognitive bias refers to the ability that people have to selectively attend to and recall information, or to distort information. Clinically, the most widely known aspect of cognitive bias are the cognitive distortions (unhelpful thinking styles) identified by Beck, examples of which include arbitrary inference, over-generalization, and dichotomous thinking (Beck, 1963). Harvey, Watkins, Mansell, and Shafran (2004) define reasoning as “thinking that is concerned with deducing conclusions, generating judgements, and testing hypotheses in a logical and coherent way.” They go on to describe a number of ways in which reasoning processes can become biased with the frequent “result that the conclusion drawn differs from objective reality”. Biases in reasoning or information processing are not necessarily dysfunctional but they often play important roles in maintaining clinical problems, including anxiety and mood disorders. Some forms of cognitive bias which are important in CBT include:
  • biased interpretation of ambiguous stimuli, which might include misinterpreting someone’s facial expression;
  • making biased attributions such as misinterpreting the degree to which the cause of an event is to do with ourselves, or misinterpreting the degree to which the cause of an event is stable or transient;
  • biased expectancies, such as a patient with anxiety expecting that negative outcomes are very likely to happen;
  • biased heuristics, such as the emotional reasoning heuristic whereby mood influences the conclusions an individual draws.
