How to identify the Bandwagon fallacy?

Why is popularity confused with truth?

The bandwagon fallacy assumes something must be true or good simply because many people believe or support it. Media platforms amplify this tendency through trends, viral content, and public polls.

Examples include claiming a diet works because millions follow it or declaring a belief valid because it is popular online. Popularity reflects social behavior, not accuracy or credibility.

To avoid this fallacy, evaluate the claim on its own merits. Ask whether the popularity is supported by evidence or simply used as a shortcut to persuade.
