Question

Quizplus · Accepted Answer

Greater expertise has been shown to lead to greater persuasion, as individuals who are perceived as knowledgeable and credible on a given topic are more likely to convince others to adopt their point of view. However, it should be noted that there may be a threshold beyond which additional expertise does not increase persuasion, and that other factors (such as the communicator's likability or perceived trustworthiness) can also play a role.
