I saw a reel about a woman whose goal for 2025 was to get rejected 1000 times. She "failed" to get rejected 7% of the time, so by the end of the year, she had a new citizenship, a role in a commercial, a pageant win, and more. I'm aiming for more rejections this year.

One thing about Critikid is that I’m making almost all the site content by myself. I don’t have an editor, so it's inevitable that some errors will slip by me. So if you ever spot a mistake on the site (even just a typo), I'd appreciate you letting me know. My email address is on the site.

In conversations about science, I often hear comments like: "It's just a theory. I'll take it seriously if it becomes a fact." This shows a misunderstanding of what these words mean in science. To help clear up the confusion, I made a FREE worksheet. Get it here: critikid.com/worksheets/f...

Informal fallacies are context-dependent. This means same phrase can be a fallacy in one case and reasonable in another. If we teach fallacies without that nuance, people might start mislabelling all "fallacy-shaped" phrases as fallacies.

I’ve posted this puzzle on a few times. In the comments, about 70-80% of people get it wrong, but for two different reasons (split about 50-50). About half of those who get it right get it right for the wrong reason. Only a small percent of people figure it out. More puzzles: critikid.com/puzzles

It is becoming more common for people to call out logical fallacies by name. Some logical fallacies, however, are prevalent and yet rarely discussed. Read about 3 of them in my latest article for @psychologytoday.com: www.psychologytoday.com/us/blog/crit...

You commit the appeal to stone fallacy when you dismiss a claim as absurd without giving any reason or evidence. It can show up like “That’s nonsense,” “Be serious,” or “That’s obviously false.” 1/5

A common logical fallacy you almost never hear about is the historian's fallacy. You commit the historian's fallacy when you judge a past decision as obviously obviously wrong using information that wasn't available at the time. 1/

Since I've been talking about the problematic vagueness of the Monty Hall problem, here's my attempt to pose the puzzle it in a clearer way. critikid.com/puzzles/mont...

Why are people falling for pseudoscience, rejecting experts, and trusting TikTok over decades of research? In her guest post for Critikid's blog, Chloe Lipton addresses these questions. critikid.com/scientific-m...

This is the original Monty Hall problem, posed by Steve Selvin as a Letter to the Editor in The American Statistician in 1975, 15 years before it was made famous by Marilyn vos Savant's column in Parade Magazine.

Here's a variation of the Monty Hall problem: As usual, you are on a game show i which there are 3 doors: one hides a car, two hide goats. You win if you pick the door with the car.

Marilyn vos Savant's framing of the Monty Hall problem was slightly unclear. Although she said the host *knows* what's behind the doors, it doesn't follow from this that he *was guaranteed to* open a door with a goat. Her version requires us to assume two things:

Critikid's social media simulator features a variety of posts designed to teach kids how to spot common misinformation tactics. These include examples of logical fallacies, fear-mongering, pseudoscience, clickbait, sensationalized headlines, and AI-generated images.

Logical fallacies are bad arguments or flaws in reasoning. They often come up in conversation and debate. Sometimes people commit logical fallacies intentionally to try to win arguments, but at other times it's accidental. (Continued)

It is sometimes difficult for adults to remember what it was like when they didn't know the names for their feelings or what to do about them. We forget that it was a skill that we had to learn. 1/

I wasn't introduced to formal logic until I was 18 in university. In my experience, teens can learn it much earlier, as long as clear language is used and concrete examples are given. I designed a course specifically for 13 to 18-year-olds: critikid.com/courses/form...

Many adults struggle to admit when they’re wrong. Let's teach children that updating beliefs with new evidence is a strength, not a weakness. Milo’s Mind is a picture book about beliefs, evidence, and intellectual humility. Recommended for ages 6-9. Critikid.com/milos-mind-redirect

I post more often on Facebook (and they've actually started paying for engagement!). I'd be grateful if you followed along there 🙏. www.facebook.com/critikids

Should we be worried about AI degrading kids' critical thinking skills? Can we use AI to help kids think more critically? These are some of the questions discussed in my latest podcast with @fundafundaacademy.bsky.social. ultimateradioshow.com/ai-and-criti...

I see the Two Child Problem is going viral on social media again. I wrote this puzzle to demonstrate why it is unanswerable as typically framed: critikid.com/double-six-p...

Don’t confuse the best decision among bad options with a bad decision.

I'm working on building a list of critical thinking activities for teens that require little to no prep or materials. It's a work-in-progress, but you can see the first activity I came up with here. If you have any ideas, please leave them in the comments! critikid.com/critical-thi...

Pseudoscience seller: I treat the root cause, unlike doctors who just treat symptoms. Science: Your treatment doesn't work beyond placebo. Pseudoscience seller: But placebo makes people *feel* better.

What do you think of these quotes by professor of neuroscience, psychology, and education, Mary Helen Immordino-Yang?

Clips of street or campus debates often frame an opponent’s stunned silence as evidence that a brilliant point was made. But in my experience, it's the most deeply flawed arguments that leave me speechless, wondering, "Where do I even begin?"
