Learning, under fire

The map

Areas of learning first. Open an area to see its claims, or use the diagram below for how beliefs connect.

The two big questions: Q1 How do humans actually learn, and what helps them learn best? Q2 How does that work in practice: in school, with screens, and with AI as one of the tools?

How the beliefs connect

Arrows show that one claim depends on or relates to another. Each claim shows its attacks as dots, oldest first.

Claim mapThe two guiding questions, the claims that serve them, and how the claims depend on or relate to each other. Newly added claims are grouped at the bottom and name their questions inside the box.
