Question

Quizplus · Accepted Answer

The two major components of communicator credibility are trustworthiness and expertise. Trustworthiness relates to how truthful and reliable the communicator is perceived to be, while expertise relates to the extent to which the communicator is seen as knowledgeable and skilled in the topic they are discussing. While attractiveness and likeability may contribute to the overall effectiveness of a message, they are not the primary components of communicator credibility. Similarly, similarity may increase audience identification with the communicator, but it is not a necessary component of credibility.
