Abstract

 

It is widely believed that information spreads through a social network much like a virus, with “infected individuals transmitting it to their friends, enabling information to reach many people. However, studies of social media indicate that most information epidemics fail to reach viral proportions. I show that cognitive constraints fundamentally distinguish social contagion from viral contagion. Specifically, people have limited attention, which they divide over all incoming stimuli. This makes highly connected people less “susceptible to infection and stops information spread.
