Dr. Val Curtis, the director of the Hygiene Center at the London School of Hygiene & Tropical Medicine, had spent years trying to persuade people in the developing world to wash their hands habitually with soap. Diseases caused by dirty hands kill a child somewhere in the world about every 15 seconds. “There are fundamental public health problems, like hand washing with soap, that remain killers only because we can’t figure out how to change people’s habits,” Dr. Curtis said. “We wanted to learn from private industry how to create new behaviors that happen automatically.” To overcome this hurdle, Dr. Curtis called on three top consumer goods companies to find out how to sell hand-washing the same way they sell Speed Stick deodorant and Pringles potato chips. The companies that Dr. Curtis turned to — Procter & Gamble, Colgate-Palmolive and Unilever — had invested hundreds of millions of dollars finding the subtle cues in consumers’ lives that corporations could use to introduce new routines. Through experiments and observation, social scientists like Dr. Carol Berning (recently retired from P&G) have learned that there is power in tying certain behaviors to habitual cues through relentless advertising. “Creating positive habits is a huge part of improving our consumers’ lives, and it’s essential to making new products commercially viable” said Dr. Berning.
