What it practises
- Deep reflection & analysis: Slowing down: weighing evidence, spotting weak arguments and explaining why something worked.
- Sustained focus: Longer sessions of steady effort, with check-ins when you start to slow down.
Fast games can crowd out slow thinking, so this skill uses untimed games and written reflection.
Quick lesson: What really follows
A conclusion must follow from the clues alone. “All red boxes are heavy” does not mean every heavy box is red. Sometimes the honest answer is “you can’t tell yet”.
Check question
All dogs have four legs. Rex has four legs. What follows?
- Rex is definitely a dog
- Rex is not a dog
- We can’t tell if Rex is a dog
- All four-legged animals are dogs
Answer: We can’t tell if Rex is a dog. Lots of animals have four legs, so Rex might not be a dog.
