Which appeal technique focuses primarily on vanity and ego satisfaction?

The technique that focuses primarily on vanity and ego satisfaction is appeal to flattery. This type of appeal seeks to persuade an audience by complimenting or praising them in a way that aligns with their self-image or desires for recognition. By highlighting positive qualities, achievements, or characteristics, the communicator aims to make the audience feel good about themselves, enhancing their sense of self-worth and encouraging them to respond favorably to the message being delivered.

In this context, flattery works by creating a positive emotional response, prompting the audience to align with the message or action suggested by the speaker because it resonates with their desires for approval and admiration. Flattery can be particularly effective in marketing and advertising, where appealing to consumers' identities and aspirations can drive them to make a purchase or embrace a particular viewpoint.
