Structural holes in social networks

The NYT has this piece profiling the work of Ronald Burt that suggests that new ideas tend to come from people whose social networks span "structural holes" and link different social/workplace networks. The thesis that new ideas emerge at the interface between functional areas makes intuitive sense.

It turned out that the highest-ranked ideas came from managers who had contacts outside their immediate work group. The reason, Mr. Burt said, is that their contacts span what he calls "structural holes," the gaps between discrete groups of people. "People who live in the intersection of social worlds," Mr. Burt writes, "are at higher risk of having good ideas."

People with cohesive social networks, whether offices, cliques or industries, tend to think and act the same, he explains. In the long run, this homogeneity deadens creativity. As Mr. Burt's research has repeatedly shown, people who reach outside their social network not only are often the first to learn about new and useful information, but they are also able to see how different kinds of groups solve similar problems.
