What it sounds like
- A celebrity said this supplement works, so it must.
- "A movie star says this investment app is safe." Lovely. Does the movie star also audit financial risk between takes?

What is happening underneath?
Using an authority figure as proof when their expertise is irrelevant, weak, or unsupported.
Authority can be useful evidence when the authority is relevant, transparent, and supported. The fallacy appears when status substitutes for proof.
How to tell
- The cited authority is outside their expertise, unnamed, paid, cherry-picked, or presented as the end of the conversation.
Why people use it
- Borrowed credibility is faster than building a real case.
How to combat it
- Say: "What is their relevant expertise, and what evidence are they relying on?"
Manipulation watch
How this gets used on people.
- Influencer ads run on this constantly: authority by fame, lab coat, podcast microphone, or confident jawline.
