60秒科学:如何令思想深入人心
A Web-based experiment in which an idea was planted found greater penetration 1 and more rapid spread of the idea in a dense 2 network of participants with overlaps 3 compared with in a loose network. Cynthia Graber reports
一项基于网络的实验表明，在人际关系错综复杂的人际网中，思想的传播深度和速度都比关系稀松的人际网高。
Diseases can spread quickly. Someone with a cold infects a few casual contacts, who in turn infect others. Ideas can also spread that way, along so-called random 4 networks. But Damon Centola at MIT says that ideas and beliefs spread faster and more efficiently 5 when they’re reinforced in clustered networks, with overlapping 6 connections among the members.
Centola recruited more than 1,500 participants for what was billed as a Web-based health community. Each had an anonymous 7 profile and was matched with health buddies 8. In one group, a minimal 9 number of links connected the participants. The other group was denser 10, with redundant 11 links.
In each group, a seed participant was planted with an idea: to register for an online health forum 12. Whenever a member registered, the member’s contacts got the message. Ultimately, 54 percent of the participants in the clustered network signed up, compared with only 38 percent in the random nework. And the behavior spread about four times faster in the clustered groups. The study is in the journal Science.
Centola thinks people are more swayed when they hear that multiple contacts are trying something new and that public health officials should take advantage of clustered networks to encourage people’s healthful behaviors.
