Don't get tricked.

Logical fallacies, explained simply. One a week.

The tricks ads, posts, and people use on you, written plain enough for a room of teenagers. Not politics. Not sides. Just how the tricks work, so you can see them coming.

A new one every week · the video and the long version

the whole series in one line Feel whatever you feel. Then check. You don't have to stop feeling things to think clearly. You just have to notice when a feeling is being used in place of a reason, and go look. @heykayandco

The internet is lying to you, and then you repeat it. Not because you're dumb. Because the tricks are good, they're everywhere, and nobody taught us the names. This series is the names.

Each one gets a short video and a page like the one below, with more examples than fit in sixty seconds: one from home, one from online, one from somebody selling something. Same closer every time, because it's the only rule that matters.

How to use these

  1. Learn one name a week. Not all of them at once. One, until you catch it in the wild without trying.
  2. Catch it in yourself first. You use these too. Everybody does. It's much easier to spot in other people once you've seen yourself do it.
  3. Say the name out loud. At our house, when somebody uses one, we name it and look it up. Nobody's in trouble. We just learned something.
  4. Check the source. Whatever you feel about a post, go to where it came from. Read both sides if there are sides. Then decide.

Why I'm doing this

I have two teenagers and a phone, same as you. I watched how fast a feeling turns into a belief when it comes in a thirty-second clip, and I didn't want my kids repeating things they'd never checked. Or me, honestly.

We found a kids' guidebook to logical fallacies, and it turned out to be the clearest explanation of this stuff I'd ever read, for any age. We keep it on the shelf. When one of the boys argues like a TV commercial, we pull it out together. That's where this series started.

The book behind the series.

The Tuttle Twins Guide to Logical Fallacies. Written for kids. Works on adults. Read it before you argue with me in the comments.

Questions

What is a logical fallacy in simple terms?

A mistake in reasoning that makes a bad argument look like a good one. Some are accidents. A lot of them are tricks.

What age can kids learn these?

If a kid can argue for a later bedtime, they can learn what a bad argument looks like. Ours are 12 and 14.

How often is a new one posted?

One a week. Video on Instagram, TikTok, and YouTube. The long version with extra examples lives here.

Do you teach these to your own kids?

No lessons. When one of them uses a fallacy, I name it and we look it up together. That's the whole method.
