Expert Power is based on:

• A. Personal magnetism.
• B. Coercive control.
• C. The authority of the position.
• D. The target person's belief that the agent possesses special knowledge.

Answer: (D)

Expert power comes from the belief that you have specialized knowledge or skills that are valuable in the situation. People defer to you and follow your guidance because they think you know something they don’t, and your credibility and expertise justify their trust. This power grows when you demonstrate competence, stay current, and apply your knowledge effectively in real problems.

In a fire service context, a captain who understands advanced fire dynamics or rescue techniques earns expert power because crew members trust that captain’s technical judgment during complex incidents.

The other forms describe different bases of influence: personal magnetism relies on likability, the authority of a position comes from the official rank or title, and coercive control depends on the ability to punish. Expert power is specifically about the target’s belief in the agent’s special knowledge.
