In the availability bias individuals estimate future probabilities by how easily they recall a past event. An easily recalled event is more quickly associated with (fit to) new information. The problem is worsened by the fact that individuals’ memories can be incomplete or biased. The confirmation bias is when individuals tend to notice only information that agrees with their perceptions or beliefs. They look for confirming evidence while discounting or even ignoring evidence that contradicts their beliefs or their perceptions. In the framing bias individuals view information differently depending on the way it is presented and received. |
