How Do Good Ideas Spread?

Atul Gawande in the New Yorker:

Many of the changes took practice for her, she said. She had to learn, for instance, how to have all the critical supplies—blood-pressure cuff, thermometer, soap, clean gloves, baby respiratory mask, medications—lined up and ready for when she needed them; how to fit the use of them into her routine; how to convince mothers and their relatives that the best thing for a child was to be bundled against the mother’s skin. But, step by step, Sister Seema had helped her to do it. “She showed me how to get things done practically,” the nurse said.

“Why did you listen to her?” I asked. “She had only a fraction of your experience.”

In the beginning, she didn’t, the nurse admitted. “The first day she came, I felt the workload on my head was increasing.” From the second time, however, the nurse began feeling better about the visits. She even began looking forward to them.

“Why?” I asked.

All the nurse could think to say was “She was nice.”

“She was nice?”

“She smiled a lot.”

“That was it?”

“It wasn’t like talking to someone who was trying to find mistakes,” she said. “It was like talking to a friend.”

That, I think, was the answer. Since then, the nurse had developed her own way of explaining why newborns needed to be warmed skin to skin. She said that she now tells families, “Inside the uterus, the baby is very warm. So when the baby comes out it should be kept very warm. The mother’s skin does this.”

A fascinating look at how to successfully create behavioral change on a large scale. Hint: do it on a small scale.
