You're very welcome! I posted a year ago, so it's probably due for an update. There's been a lot of research on anchoring in the last year

Since "Thinking, Fast and Slow" was published in 2011, science has faced the replication crisis. Many famous findings have failed to reproduce, including many from the book. It remains a valuable book on judgment, but it should be read with caution. I wrote this to help: critikid.com/a-modern-gui...

A Modern Guide to Thinking, Fast and Slow - Critikid

A chapter-by-chapter analysis of Kahneman's text with a focus on the replication crisis, clarifying which findings remain solid and which have not held up to scrutiny.

Pseudoscience is not the same as bad science. Bad science is a faulty version of good science. It follows the scientific method, but it makes mistakes. Pseudoscience, on the other hand, is not science at all. Read more: critikid.com/how-to-spot-...

Can you solve the gummy bear puzzle? Thank you to Henk Tijms for sharing a variation of this puzzle with me.

Text saying: There are 10 gummies in a bag.
Two of them are orange and the other eight are yellow.

You will take gummies from the bag, one at a time at random, and eat them until you take out a gummy of the other colour. When this happens, you put it back in the bag and start over.

What are the chances that the last gummy you eat is orange?

There are 3 puzzles a day... do you think all 3 should have the 3 steps or just the first one?

Stephanie Simoes @critikid.bsky.social · 27/09/2026

Right now, allsome.app puzzles work in 3 steps: First you solve 2 circles, then 3, then 4, as shown in the pictures. Do you think it would be better if the first two steps were skipped and you just had to solve 4 circles right away?

...and were accepted as subjects at a parapsychology lab at Washington University. Using ordinary magic tricks, they appeared to bend spoons and produce other paranormal effects. The hoax exposed serious weaknesses in the lab's methods.

One example magicians exposing pseudoscience is Project Alpha. Steve Shaw (aka Banachek) and Michael Edwards, supported by magician James Randi, posed as people with psychic abilities (cont'd)

Pseudoscience looks like science in that it uses technical language and "experiments," but without the safeguards that make science reliable. Like stage magic, it creates a convincing illusion. The difference is that magicians are honest about what they are doing.

"Everyday Concepts" has 54 puzzles that don't require much specific knowledge. Here, players can focus on the logical relationships. "Biology" has 22 puzzles, many of which require a grade 6+ level of knowledge. That means there's an extra challenge of applying subject knowledge.

We just released a free new logic puzzle game! Nobody has tried it yet (besides my husband and me), so I would really appreciate some feedback. The game is to make diagrams that show the correct relationships between the categories. Try it: allsome.app

Developing the questions for the new puzzle app we're building is a workout for my brain! The first version (a web app) should be out in a day or two.
