A FEW years ago, a self-described “militant liberal” named Val Curtis decided that it was time to save millions of children from death and disease. So Dr. Curtis, an anthropologist then living in the African nation of Burkina Faso, contacted some of the largest multinational corporations and asked them, in effect, to teach her how to manipulate consumer habits worldwide.
Dr. Curtis, now 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 and disorders caused by dirty hands — like diarrhea — kill a child somewhere in the world about every 15 seconds, and about half those deaths could be prevented with the regular use of soap, studies indicate.
But getting people into a soap habit, it turns out, is surprisingly hard.
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.
