What is the term for the reasoning that suggests if a popular opinion is expressed, it must be correct?

The term that describes the reasoning suggesting that if a popular opinion is expressed, it must be correct is known as the bandwagon effect. This phenomenon occurs when individuals adopt certain behaviors, follow trends, or make decisions primarily because other people are doing so. Essentially, it reflects a tendency to align with the majority, assuming that popular consensus constitutes truth or correctness. This reasoning can be particularly prominent in social contexts where peer pressure or prevailing norms influence decision-making. Consequently, individuals may dismiss critical thinking or personal judgment in favor of conformity to the majority opinion.
