Real Knowledge Frameworks
Puzzles can be tied to structured frameworks — real bodies of knowledge with named rules and categories. Players don't just memorize labels — they learn to identify patterns, apply principles, and reason through problems the way experts do.
- Attacking Faulty Reasoning — T. Edward Damer's taxonomy of logical fallacies — identify which criterion of a good argument has been violated.
- Systems Thinking — Based on the work of Donella Meadows, Peter Senge, Jay Forrester and more — see feedback loops, delays, and structural patterns instead of surface-level events.
