How Does The Fallacy Fallacy | Idea Channel | PBS Digital Studios Work?

The fallacy fallacy is when people think something isn’t true just because someone used a bad argument to try and prove it.

Imagine you're trying to convince your friend that ice cream is the best snack ever, but you say, "I like ice cream, so it must be the best." That’s not a very strong reason, it's more like saying, "I like it, so it has to be the best!" But just because your argument was weak doesn’t mean ice cream isn’t actually the best. That’s the fallacy fallacy in action.

Why It Happens

Sometimes people get confused between a bad argument and the real truth. Like if you say, "I saw a cat wearing a hat, so it must be magical," but someone else says, "You can't prove that just because of one weird sight!" They might think the whole idea is wrong, when really, maybe the cat is magical, and your argument was just silly.

So remember: even if someone uses a funny or not-so-good reason to say something, it doesn’t mean that thing isn’t true. It’s like believing a broken toy can't do anything just because it's broken.

Examples

  1. A kid says, 'You can't trust anyone because my dog barked at me,' and you dismiss their whole idea just because of that silly example.
  2. Someone argues, 'I believe in ghosts because I saw a shadow,' and you say it's not true because they used a weak argument.
  3. A friend says, 'I'm right because everyone else is wrong,' and you think that's a bad reason but ignore the actual facts.
