Social Influence Online

Text-based communication via the Internet has provided new opportunities to study social influence and persuasion. Specifically, Guadagno and Cialdini (2005) contend that the effectiveness of social influence attempts have yet to be thoroughly investigated online. To test Guadagno and Cialdini's contention, the present study examined whether the social influence principles of likability and social validation impacted individuals' willingness to comply with a request when the setting is online. Results revealed that social validation affected compliance, but communicator likability did not. Thus, our results indicate that contrary to previous work in offline contexts, not all social influence principles are effective online. Explanations for these differences are discussed.
