Abstract

Abstract: Persuasion is at the core of norm creation, determining the success of solutions to problems such as the tragedy of the commons, and the emergence of collective actions. In this paper, we show that the directionality and topology of friendship ties affects how effectively individuals can impact the behavior of each other. Moreover, we find that people are typically poor at perceiving the character of their friendship ties and that this significantly limits their ability to shape the behavior of others and might lead to failures in establishing common strategies and in persuading others to act. We then suggest strategies to overcome this limitation relying on topological characteristics of the perceived friendship network.
