Choice-supportive bias refers to the @Cognitive Bias to attribute more positive qualities to a chosen option and more negative qualities to rejected alternatives after a decision has been made. In psychology, this effect—sometimes called post-purchase rationalization—suggests that individuals may unconsciously minimize the faults of their selections while exaggerating the shortcomings of other possibilities. This bias often shapes how memories of decisions are stored, with positive features being linked to the chosen option and negative aspects assigned to the rejected one. Such @memory distortions influence how people experience satisfaction or regret about their choices, impacting future decision-making. Cognitive scientists note that the process underlying choice-supportive bias is closely related to how @subjective attributions are formed, involving personal motives, prior beliefs, and the surrounding social @context. Notably, both accurate and inaccurate memories can arise through the same mechanisms, as the brain cannot always distinguish between the origins of information when it is encoded and recalled. Choice-supportive bias is one of several cognitive biases that affect how individuals process, evaluate, and remember their experiences.

Example

If a person chooses option A instead of option B, they are likely to ignore or downplay the faults of option A while amplifying those of option B. Conversely, they are also likely to notice and amplify the advantages of option A and not notice or de-emphasize those of option B.
