Answer:
The common belief that we aren’t influenced by media messages but other people are is known as: the third-person effect.
Explanation:
It was in 1983 that sociologist W. Phillips Davison first articulated what is now known as the third-person effect. According to his theory, this effect shows a tendency one has to underestimate the effects of a mass communicated message over oneself. One tends to believe that others are more affected than one is, overestimating the power media has over others. This belief is a result of personal biases.
