Although the results may not be that surprising to readers of this blog, I was intrigued by Wired Science's coverage of a new paper in the journal Science that showed that highly interconnected soical networks are much more powerful that randomly connected groups for changing behaviors.
Unlike infectious diseases and news, behavior change spreads faster through online networks that have many close connections instead of many distant ties. Redundancy is key, as people are more likely to engage in a behavior if they see many others doing it.
In other words, when starting a new, healthy behavior (say exercise), knowing ten random people who run may help motivate you. But if that group of ten people is a close-knit group of running buddies who all know each other, the chances of sticking to your new routine go up. Way up.
