What is the Alleged Certainty Fallacy?
The name hints to how to the fallacy works. Someone makes a claim, asserting that is true without giving reasons why it is true. The conclusion they draw is final according to them, often accompanied by the statement “everyone knows that,” etc.
The alleged certainty fallacy occurs when a person claims that something is certain when it’s actually up for debate. This individual does not bother to bring in evidence or reasons that justify their claim.
Examples of the Alleged Certainty Fallacy
We’re all indebted to our mothers. Everyone knows this.
Everyone knows that corporal punishment is the best use of discipline in children.
It’s not a debate that the sciences are the most important field in academia.
💡 Key Point: Note how each of these examples make absolute statements about things that, in reality, are up for debate. It’s likely that these people are making these claims so confidently because they’re surrounded by a people or culture in which these ideas are commonly held. But just because they are typical in your social, ideological, or cultural sphere does not mean it is typical or everyone single human. Neither does it mean that they are not up for debate.
We are more likely to present debatable ideas as absolute and not backed by a reason when we are surrounded by many people who think the same way as we do. Click To TweetQuiz Time!
