Ahh, the Sweet Smell of Goodness

If you are hoping to make the world a better place, you might want tostock up oncitrus-scented Windex. Apparently, the fresh smell brings out the best in people. In fact, researchers have found a dramatic improvement in ethical behavior when people spend time in a room freshly spritzed with the citrus-scented cleaner.

The study, titled, "The Smell of Virtue," was unusually simple and conclusive. Participants engaged in several tasks,with just one difference--some worked in an unscented room, while others worked in the Windexed room. As a test of whether clean scents would enhance fairness, subjects played a classic trust game. They received $12 in cash, supposedly fromaperson trusting them to divide it fairly.Subjects in clean-scented roomsreturnedon average, $5.33 compared to subjects in the unscented room who gave back $2.81.

Another experiment evaluated whether clean scents affected charitable behavior. Those in thefresh-scentedroom once again demonstrated that the smell of cleanliness is next to godliness. When asked to rate their interest in volunteering for a Habitat for Humanity project, on a scale of one to seven, they averaged 4.21, which was significantly higher than those in the scent-less room, whose interest scored 3.29. They were also much more willing to ante up for the same cause. In fact, 22 percent of participants under the influence of Windex said theyd like todonate money, compared to only 6 percent of those who breathed unscented air.

Katie Liljenquist, assistant professor of organizational leadership at BYUs Marriott School of Management, is the lead author of the study, which will be published in an upcoming issue of Psychological Science. Co-authors are Chen-Bo Zhong of the University of Torontos Rotman School of Management and Adam Galinsky of the Kellogg School of Management at Northwestern University. Zhong and Liljenquist have previously demonstrated a link between morality and physical cleanliness. while this study examined the influence of the physical environment on morality, withthe citrus-scent conveying cleanliness. While the clean smell proved a powerful factor in their actions, the participants later said they hadn't noticed the scent in the room. Basically, our study shows that morality and cleanliness can go hand-in-hand, said Galinsky of the Kellogg School. Researchers have known for years that scents play an active role in reviving positive or negative experiences. Now, our research can offer more insight into the links between peoples charitable actions and their surroundings. The researchers see implications for workplaces, retail stores and other organizations that have relied on traditional surveillance and security measures to enforce rules. This is a very simple, unobtrusive way to promote ethical behavior, said Liljenquist, So, maybe it's time to clean up Wall Street, Congress and corporate America. Grab your spray guns and let the spritzing begin.
