Dim the lights if you need to make a big decision
The next time you want to turn down the emotional intensity before making an important decision, you may want to dim the lights first.
A new study shows that human emotions, whether they are positive or negative, are felt more intensely under bright lights.
“Other evidence shows that on sunny days people are more optimistic about the stock market, report higher wellbeing, and are more helpful while extended exposure to dark, gloomy days can result in seasonal affective disorder,” says Alison Jing Xu, assistant professor of management at the University of Toronto Scarborough.
“Contrary to these results, we found that on sunny days depression-prone people actually become more depressed,” she says, pointing to peaks in suicide rates during late spring and summer when sunshine is abundant.
For a new study published in the Journal of Consumer Psychology, Xu and Aparna Labroo of Northwestern University asked participants to rate a wide range of things—the spiciness of chicken-wing sauce, the aggressiveness of a fictional character, how attractive someone was, their feelings about specific words, and the taste of two juices—under different lighting conditions.
The results show that under bright lights emotions are felt more intensely. In the brighter room participants wanted spicier chicken wing sauce, thought the fictional character was more aggressive, found the women more attractive, felt better about positive words and worse about negative words, and drank more of the “favorable” juice and less of the “unfavorable” juice.
The effect bright light has on our emotional system may be the result of it being perceived as heat, and the perception of heat can trigger our emotions. “Bright light intensifies the initial emotional reaction we have to different kinds of stimulus including products and people,” Xu says.
The majority of everyday decisions are also made under bright light. So turning down the light may help you make more rational decisions or even settle negotiations more easily.
“Marketers may also adjust the lighting levels in the retail environment, according to the nature of the products on sale,” Xu says. “If you are selling emotional expressive products such as flowers or engagement rings it would make sense to make the store as bright as possible.”
The effect is likely to be stronger on brighter days around noon when sunlight is the most abundant and in geographic regions that experience sunnier rather than cloudier days.
