Moral Behavior Linked to Cleanliness

Moral Behavior Linked to Cleanliness A new study discovers people are naturally more fair and charitable when they are in clean-smelling environments.

The research found a dramatic improvement in ethical behavior with just a few spritzes of citrus-scented Windex.

Katie Liljenquist, assistant professor of organizational leadership at BYU’s Marriott School of Management, is the lead author on the piece in a forthcoming issue of Psychological Science.

Liljenquist and fellow researchers see implications for workplaces, retail stores and other organizations that have relied on traditional surveillance and security measures to enforce rules.

“Companies often employ heavy-handed interventions to regulate conduct, but they can be costly or oppressive,” said Liljenquist, whose office smells quite average.

“This is a very simple, unobtrusive way to promote ethical behavior.”

Perhaps the findings could be applied at home, too, Liljenquist said with a smile. “Could be that getting our kids to clean up their rooms might help them clean up their acts, too.”

The study titled “The Smell of Virtue” was unusually simple and conclusive. Participants engaged in several tasks, the only difference being that some worked in unscented rooms, while others worked in rooms freshly spritzed with Windex.

The first experiment evaluated fairness. As a test of whether clean scents would enhance reciprocity, participants played a classic “trust game.” Subjects received $12 of real money (allegedly sent by an anonymous partner in another room).

They had to decide how much of it to either keep or return to their partners who had trusted them to divide it fairly. Subjects in clean-scented rooms were less likely to exploit the trust of their partners, returning a significantly higher share of the money.

People who were in the clean-scented room gave back an average of $5.33. But people in the normal room gave back only an average of $2.81.

The second experiment evaluated whether clean scents would encourage charitable behavior. Subjects indicated their interest in volunteering with a campus organization for a Habitat for Humanity service project and their interest in donating funds to the cause.

Participants surveyed in a Windex-ed room were significantly more interested in volunteering (4.21 on a 7-point scale) than those in a normal room (3.29). Furthermore, 22 percent of Windex-ed room participants said they’d like to donate money, compared to only 6 percent of those in a normal room.

Follow-up questions confirmed that participants didn’t notice the scent in the room and that their mood at the time of the experiment didn’t affect the outcomes.

“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 people’s charitable actions and their surroundings.”
