It is a special case of choice-supportive bias.

Choice-supportive bias leads to an increased liking of one's choices, including purchases.

Random Selection: People do not show choice-supportive biases when choices are made randomly for them.

Therefore choice-supportive bias would arise because their focus was on how they felt about the choice rather than on the factual details of the options.

Choice-supportive bias often results in memories that depict the self in an overly favorable light.

Studies have shown that when younger adults are encouraged to remember the emotional aspect of a choice, they are more likely to show choice-supportive bias.

A study of the Lady Macbeth effect showed reduced choice-supportive bias by having participants engage in washing.

In cognitive science, choice-supportive bias is the tendency to retroactively ascribe positive attributes to an option one has selected.

In another experiment, experimenters were able to reduce choice-supportive bias by having subjects engage in forms of self-cleaning.

Choice-supportive bias occurs when people distort their memories of chosen and rejected options to make the chosen options seem more attractive.

This can alter the way neurons respond to future input, and therefore cognitive biases, such as choice-supportive bias can influence future decisions.

Although general memory problems are common to everyone because no memory is perfectly accurate, older adults are more likely than younger adults to show choice-supportive biases.

This reveals that choice-supportive biases arise in large part when remembering past choices, rather than being the result of biased processing at the time of the choice.

Choice-supportive bias is potentially related to the aspect of cognitive dissonance explored by Jack Brehm (1956) as postdecisional dissonance.

Within the context of cognitive dissonance, choice-supportive bias would be seen as reducing the conflict between "I prefer X" and "I have committed to Y".

A choice-supportive bias is seen when both correct and incorrect attributions tend to favor the chosen option, with positive features more likely to be attributed to the chosen option and negative features to the rejected option.

Consistent with choice blindness, Henkel and Mather found that people are easily convinced by false reminders that they chose different options than they actually chose and that they show greater choice-supportive bias in memory for whichever option they believe they chose.
