The type of propaganda that seeks to make someone seem more relatable is "plain folk." This technique aims to portray a person or a group as ordinary, down-to-earth individuals who share the same values, beliefs, and struggles as the audience. By presenting themselves as just like the average person, this type of propaganda seeks to establish a connection with the audience and gain their trust and support.
Examples of the "plain folk" propaganda technique can be seen in political campaigns where candidates emphasize their humble backgrounds or everyday experiences to appeal to voters. This strategy is also used in advertising to make products or services appear more approachable and suitable for the everyday consumer.
In contrast, the other types of propaganda mentioned:
1. The straw-man fallacy involves misrepresenting someone's argument to make it easier to attack, but it does not focus on making someone seem relatable.
2. Bandwagon propaganda aims to persuade people to do something because everyone else is doing it, rather than making someone relatable.
3. Glittering generalities use emotionally appealing words or phrases that are vague and often subjective, but they do not necessarily focus on making someone relatable.
Therefore, in the context of making someone seem more relatable, the "plain folk" propaganda technique is the most relevant choice.
