What type of propaganda persuades through the endorsement of a famous person?

Testimonial propaganda is characterized by the use of endorsements from famous individuals or celebrities to persuade an audience. This type of propaganda relies on the credibility, popularity, or appeal of the endorser to convince others to adopt a viewpoint or purchase a product. By leveraging a well-known figure's influence, testimonial propaganda can create a sense of trust and authority around the message being promoted, regardless of the actual merits of the product or idea.

This method effectively taps into the audience's admiration for the celebrity, often leading them to associate the positive attributes of the endorser with the product or idea being advertised. This connection can sway opinions more powerfully than rational arguments or factual information alone.
