Good habits are arduous to undertake. However a bit of bribery can go a good distance.
That’s the discovering from an experiment in India that used rewards to get villagers hooked on routine handwashing. Whereas tying rewards to desired behaviors has lengthy been a staple of behavior formation, handwashing has confirmed tough to stay.
The rewards labored. “For those who bribe youngsters, handwashing charges shoot up,” says developmental economist Reshmaan Hussam of Harvard Enterprise College. And even simply making handwashing a nice, straightforward exercise improved well being: Youngsters in households with thoughtfully designed cleaning soap dispensers skilled fewer sicknesses than youngsters in households with out these instruments, Hussam and colleagues report in a paper to look in American Financial Journal: Utilized Economics.
Considerably, good habits lingered even after researchers stopped giving out rewards. “The truth that they discovered persistence suggests to me that members did type habits,” says Jen Labrecque, a social psychologist at Oklahoma State College in Stillwater who was not concerned with the analysis.
The research concerned 2,943 households in 105 villages within the state of West Bengal between August 2015 and March 2017. All members had entry to cleaning soap and water. Practically 80 p.c mentioned they knew cleaning soap killed germs, however initially solely 14 p.c reported utilizing cleaning soap earlier than consuming.
To objectively assess habits, Hussam’s crew devised a method to monitor handwashing within the absence of observers — whose presence sometimes makes individuals behave higher. In collaboration with the MIT Media Lab, the crew constructed a cleaning soap dispenser with a hidden sensor that recorded at any time when someone used it.

They then educated households on methods to construct good handwashing habits, resembling establishing a set off (meal time) and a routine (handwashing proper earlier than meals). In addition they made the handwashing expertise as easy and gratifying as doable, resembling through the use of scented cleaning soap and mounting the sensors the place youngsters might simply attain them. Researchers visited households each two weeks to gather information on youngsters’s well being and refill the dispensers.
Hussam’s crew divided households into a number of teams. Some households acquired solely a dispenser. Others acquired automated reviews on their each day handwashing efficiency, a social incentive to softly prod routine exercise. Nonetheless others received tickets every time someone pressed the dispenser round meal time — these tickets might be traded for toothbrushes, backpacks and different helpful gadgets. A management group acquired no dispensers.
In households that received no incentives, the crew discovered that folks used cleaning soap at dinnertime 36 p.c of the time, one to 4 months after receiving a dispenser. Those that received automated reviews used cleaning soap 45 p.c of the time. And people incomes tickets used cleaning soap 62 p.c of the time.
As soon as rewards and suggestions ceased, cleaning soap use abruptly plummeted. With little to lose, the researchers stored the sensors on. As months progressed, handwashing charges amongst households that had acquired incentives ticked barely upward. 9 months after incentives ceased, households that had acquired tickets washed their fingers 16 proportion factors greater than households that acquired dispensers solely.
The crew suspects that the return of chilly and flu season reminded dad and mom to make use of cleaning soap. Maybe “when dad and mom see that children are sniffly or sneezing, that’s once they’re triggered to make use of the machine,” Hussam speculates. Usually, “habits are tied to particular cues.”
This research exhibits the worth of spending a restricted pool of cash up entrance versus spreading it extra evenly throughout time, as is frequent in public well being campaigns, says medical epidemiologist Stephen Luby of Stanford College. “I do see the worth of front-loading behavior adoption.”
Even youngsters residing in households with only a dispenser and no rewards had higher well being than youngsters in households with no dispenser. Eight months after incentives ceased, youngsters with cleaning soap dispensers of their households skilled 38 p.c fewer days with diarrhea and 16 p.c fewer days with respiratory infections than youngsters with out dispensers. Entry to a well-designed dispenser additionally tracked to more healthy peak and weight for kids.
For product designers hoping to steer individuals towards good habits, a beneficial lesson emerges: “Consider carefully about human-centered design,” Hussam says.
