Recommendation

University of Pennsylvania professor Damon Centola argues that the more complex an idea, technology or new behavior, the less likely large networks of weak ties will promote its adoption. In an increasingly connected world of loose and long ties, this matters. Through reference to extensive experimentation and research, Centola shows that the spread and adoption of important ideas – like getting vaccinated, voting or adopting healthier behaviors – require tight networks of strong ties.

Take-Aways

  • Social contagions include ideas and behaviors.
  • Weak ties in networks may slow the spread of innovation and behavior change.
  • Strong ties don’t necessarily work better than weak ties.
