Do Clean Smells Encourage Clean Behavior

Years ago, social scientists introduced the broken-windows theory of crime control, which assumed that if a neighborhood looked orderly and cared for — with no broken windows — potential wrongdoers would be dissuaded from committing crimes there. Now psychologists have proposed a similar theory, which suggests that people can be induced to behave morally when their environment smells as clean as it looks. It’s the Macbeth principle of morality, says Katie Liljenquist, professor of organizational leadership at Brigham Young University’s Marriott School of Management and lead author of the new study, to be published in Psychological Science. "There is a strong link between moral and physical purity that people associate at a core level. People feel contaminated(受污染的) by immoral choices and try to wash away their sins," says Liljenquist.

[填空题]Where was the letter probably placed many years ago

[填空题]
Three years ago, at the age of 24, Deborah Whalley decided to get rid of the "80-pound backpack" of extra weight she was carrying on her five-foot-nine frame. It wasn’t the first time that Whalley, a retail assistant manager in Toronto, had embarked on a diet.
"I lost 30 pounds in Grade 9," she recalls. "Not only did I gain the weight back in short order, but I also put on about 50 extra pounds over the next nine years. "
If you’ ve ever been on a diet, you’ ve probably discovered, as Whalley did, that taking off extra pounds is a lot easier than keeping them off. In fact, 95 percent of people who lose weight end up gaining it back.
Cycling back and forth between higher and lower weights is not just demoralizing, however. "There’s some evidence that yo-yoing within a 20-or 30-pound range puts more stress on your heart than carrying those 20 or 30 extra pounds," says Stephen Cunnane,
