8 philosophical conversation-starters (or journaling prompts) for teens: 1. Can two people look at the same evidence, think carefully, and still both be reasonable while disagreeing?

I'm hoping to make Fallacy Detectors Part 2 before the end of this year, but it's expensive because I need to hire an animator. I'm running a @ko-fi.com campaign to help fund it, but I'm only 17% of the way there. Please contribute if you can: ko-fi.com/critikid

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:

As you explore a spaceship to discover the cause of a mysterious ship-wide memory loss, you will learn how biases can distort our understanding of data. 👇

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...

My latest article for @psychologytoday.com provides a brief, simple introduction to formal logic and deductive arguments: www.psychologytoday.com/us/blog/crit...

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?"

An interesting conversation that follows a puzzle I recently shared is: What counts as a fair assumption? The puzzle was this: "Jack is looking at Anne, but Anne is looking at George. Jack is married, but George is not. Is a married person looking at an unmarried person?"

Don't get me wrong - I like "Thinking, Fast and Slow." Many of the concepts are supported by decades of research and replications. But this kind of stuff is in there, too.

On being confidently wrong:

Today I saw a post explaining "popular texting codes" to parents. The examples included things like BRB, GR8, and GTG. The irony is obvious: Parents today are the ones who invented those codes. But it reflected a bigger problem with many media/digital literacy resources 👇

I avoid the term "critical thinker." It suggests you either are one or you’re not, that it's something you can achieve and be done with. I prefer "critical thinking." It's something we all do, sometimes better than others. Even with practice, we all slip into lazy thinking at times.

Teach your kids (ages 6-9) that changing your mind when you find out you were wrong is not a weakness - it's a superpower! critikid.com/milos-mind-r...

This is the Motte and Bailey fallacy. Motte-and-bailey castles had two areas: a wide area that was hard to defend (the bailey) and small stone tower on a hill that was easier to protect (the motte). When invaders came, people abandoned the bailey and retreated to the motte. 👇

A common scenario: Someone posts a reel that's vague or missing information. They clarify in the caption. The reel gets misinterpreted by people who didn't read the caption. OP accuses them of having poor literacy skills.

"Blaise, there's a chance that aliens could come to Earth and give humans immortality and send everyone named Steven to a paradise planet and people with any other name to a hellish planet, so you should go change your name to Steven, just in case."

Should You Read "Thinking, Fast and Slow"? I often recommend this book by Daniel Kahneman as an introduction to critical thinking. It gets us thinking about our own thinking, especially about how often it goes wrong. 1/

I generally don't like word riddles of the "What is it?" form because I think the answers are often too much of a stretch. But I do like this one: What gets wetter the more it dries? What are your favourite riddles?

What online critical thinking courses does Critikid have for kids and teens?👇

Thinking critically doesn't just mean questioning what "they" tell us is true. It also means questioning our own beliefs and assumptions - and that's the hard part.

I'm as bad as Netflix. I hate it when Netflix has a gap of years between seasons of a show. And yet, it's been about a year and a half since I released Fallacy Detectors Part 1. To make things worse, it ended with a cliffhanger.
