Don't Be a Sheep: The Ad Populum Fallacy Explained

Welcome to the next installment in our Logic and Fallacies series!

In this video, we break down the Ad Populum Fallacy, also known as the Appeal to Popularity or Appeal to the People. This is one of the most common mistakes in reasoning, where the popularity of a belief is mistakenly taken as evidence that the belief is true.

From popular political opinions to social conventions and even historical scientific beliefs (like the pre-Copernican view of the universe), we show you why the crowd isn't always right, and how to spot this flawed logic.

What you'll learn in this video:

• The standard form of the Ad Populum argument: All/Most people think X, therefore X is true.
• The difference between popularity and truth.
• Key Exceptions where popularity does matter (e.g., word definitions, elections, and social conventions).
• How the fallacy is used to justify immoral or outdated social structures.

Don't let the allure of being like everyone else keep you from forming your beliefs for the right reasons.
