Which term describes the belief that something is true because many others think so?

• A. Confirmation Bias
• B. Misinformation
• C. Bandwagon Effect
• D. Echo Chamber

Answer: (C)

The main idea here is social influence: people often adopt a belief because many others appear to hold it. This is the bandwagon effect. It happens when the perceived popularity of an idea signals credibility, so someone goes along with it to fit in or avoid being different, even if there isn’t solid evidence behind it.

This fits best because it specifically describes how popularity sways belief. It’s not about seeking information that confirms what you already think (that would be confirmation bias), nor about the content being false (misinformation), nor about being in a setting that only shows like-minded views (an echo chamber). The bandwagon effect focuses on adopting beliefs due to their social popularity.
