Here are a few possible ways to respond:
Respect their Expertise: If the person's claim to being a doctor is relevant to the topic at hand, and you believe they genuinely have valuable insights, you can acknowledge their expertise and show interest in what they have to say.
Seek Clarification: If the person is using their title as a doctor to assert authority without providing sufficient evidence or explanation, you can ask them to elaborate on their point of view. Encourage them to share their knowledge and reasoning.
Challenge with Diplomacy: If you have differing opinions or information on the subject, you can respectfully express your perspective. Avoid being confrontational but engage in a constructive discussion to exchange ideas.
Consider Other Perspectives: Keep in mind that being a doctor in a specific field doesn't necessarily mean expertise in all areas. Politely suggest that multiple perspectives can contribute to a well-rounded understanding.
Example response: "I appreciate your expertise as a doctor, and I'm interested to learn from your experience. However, I've also come across other viewpoints on this matter. Let's discuss it together to gain a comprehensive understanding."
The key is to maintain a respectful and open-minded tone while encouraging a productive exchange of knowledge and ideas.
