argument_from_popular_opinion
The argument from popular opinion claims that a proposition is true or acceptable because a large number of people believe it. This is the belief-based form of the appeal to popularity: it draws its force from the assumption that many people cannot all be wrong. While popular belief sometimes serves as evidence (many independent observers reaching the same conclusion), it can also propagate errors, prejudices, and misinformation, especially when beliefs are not independently formed.
Surveys show that 78% of Americans believe that angels are real. Since the vast majority of people believe in angels, there must be something to it. You should at least take the possibility seriously.
A wellness blogger writes: 'Polls consistently show that over 70% of people believe that detox teas cleanse the body of toxins. With so many people convinced of the benefits, there's clearly something to these products worth exploring.' The widespread belief is being used as evidence for the tea's efficacy rather than clinical research.
During a town hall debate on a proposed wind farm, an opponent argues: 'I've spoken to dozens of people in this community and they all feel that wind turbines cause health problems. When that many of your neighbors believe it, you have to take it seriously.' The prevalence of the belief is presented as supporting its truth.

Social proof is a powerful heuristic: if many people believe something, it reduces the cognitive cost of independent verification. Dissenting from popular opinion also carries social risk, making conformity the path of least resistance.
Point out that popular opinion has been wrong on many historical issues (geocentrism, racial superiority). Ask whether the belief is independently formed or if it spreads through social contagion, cultural tradition, or media influence.
Popular opinion arguments appear in marketing ('millions of satisfied customers'), political discourse ('the people have spoken'), religious apologetics, and social media (viral content treated as validated).
