Why We Return to Bad Habits

A common mental miscalculation causes us to overestimate our self-control

If you have ever lost weight on a diet only to gain it all back, you were probably as perplexed as you were disappointed. You felt certain that you had conquered bad eating habits—so what caused the backslide? New research suggests that you may have succumbed to a cognitive distortion called restraint bias. Bolstered by an inflated sense of impulse control, we overexpose ourselves to temptation and fall prey to impulsiveness. Northwestern University psychologists first asked a group of smokers to take a self-control test. Unknown to the participants, the test was a pretense to randomly label half the group as having high self-control and half as having low selfcontrol. After hearing their supposed result, participants played a game that involved watching the 2003 movie Coffee and Cigarettes while challenging themselves with one of four levels of temptation, each with its own cash reward. They could keep a cigarette unlit in their mouths (for the most money), unlit in their hand, on a nearby desk or (for the lowest reward) in another room. Participants earned a prize only if they avoided smoking for the entire 95-minute film. Smokers told that they had high self-control exposed themselves to significantly more temptation than their counterparts—opting on average to watch the movie while holding a cigarette—and they failed to resist lighting up three times as often as those told they had low self-control. “Restraint bias offers insight into how our erroneous beliefs about self-restraint promote impulsive behavior,” says lead author Loran F. Nordgren of Northwestern’s Kellogg School of Management. “It helps us to understand puzzles in addiction research such as why recovered addicts often relapse after they have broken free of withdrawal symptoms.” The lesson? When you’ve made progress avoiding your indulgences and that little voice in your head tells you it’s okay to start exposing yourself to temptation again— ignore it.

About Me

In its broadest sense, science (from the Latin scientia, meaning "knowledge") refers to any systematic knowledge or practice. In its more usual restricted sense, science refers to a system of acquiring knowledge based on scientific method, as well as to the organized body of knowledge gained through such research.

Fields of science are commonly classified along two major lines: natural sciences, which study natural phenomena (including biological life), and social sciences, which study human behavior and societies. These groupings are empirical sciences, which means the knowledge must be based on observable phenomena and capable of being experimented for its validity by other researchers working under the same conditions.
