People prefer to make changeable decisions rather than unchangeable decisions because they do not realize that they may be more satisfied with the latter. Photography students believed that having the opportunity to change their minds about which prints to keep would not influence their liking of the prints. However, those who had the opportunity to change their minds liked their prints less than those who did not (Study 1). Although the opportunity to change their minds impaired the postdecisional processes that normally promote satisfaction (Study 2a), most participants wanted to have that opportunity (Study 2b). The results demonstrate that errors in affective forecasting can lead people to behave in ways that do not optimize their happiness and well-being.
