third-person effect
The Third-people effect hypothesis predicts that people tend to perceive that mass communicated messages have a differential influence on themselves and others, based on personal biases; additionally, because of this perception, people tend to take action to counteract the messages’ influence. The Third-person effect hypothesis often manifests itself through an individual’s overestimation of the effect of a mass communicated message on the generalized other, or an underestimation of the effect of a mass communicated message on themselves.
