Goal setting and self control in needed for activities like studying, saving money and dieting. But even the most disciplined person falls prey to temptation every once in a while. According to a new study in the Journal of Consumer Research, people who distort past memories of their indulgences are more likely to indulge in the future.
"We investigated the possibility that individuals may distort memories of past behavior in order to allow for indulgence in the present. In other words, people may trick themselves into thinking something like, 'I've been good on my diet lately, so I can have this piece of cake,'" write authors Frank May (Virginia Tech) and Caglar Irmak (University of Miami).
Across four studies involving eating, spending, and studying, the authors found that people distort their memories of past indulgences when faced with an opportunity to indulge. This, in turn, leads to greater levels of indulgence. In one study, the authors gave participants candy and allowed thirty minutes to pass. A bag of M&Ms was then placed in front of some participants, but not others. When asked to estimate how many calories were in the candy consumed at the beginning of the study, participants who had consumed M&Ms gave a lower calorie estimate than those who had not consumed the M&Ms. When the opportunity to indulge was not present (the M&Ms were removed), all participants gave a similar calorie estimate.
People who know they are highly impulsive might want to take steps to accurately remember both past indulgences and moments of self-control (by keeping a detailed journal, for example). "Having this information available can help a person both avoid a poor decision in the face of temptation and ensure that their past self-control behavior does not appear to be more significant than it actually was," the authors conclude.
