Which principle is associated with perceiving the communicator as an expert, thereby increasing influence?

• A. Authority/Credibility
• B. Liking
• C. Scarcity
• D. Reciprocity

Answer: (A)

The idea here is the authority principle: people are more likely to be influenced when the communicator is seen as an expert and credible. When someone projects knowledge, credentials, or confident expertise, others assume their information is reliable and feel confident following their guidance. This reduces uncertainty and boosts trust, so recommendations or instructions carry more weight. That influence is strongest when the audience lacks other information or is uncertain, and the speaker’s authority is perceived through credentials, experience, or clear, evidence-based messaging. While liking, scarcity, and reciprocity can also sway behavior in different ways, they don’t hinge on perceiving the speaker as an expert, which is the hallmark of authority/credibility.
