HOW IT WORKS Every case presents a real-world claim — the kind you'd see on Reddit, in the news, or at the dinner table. You analyze it using a 5-step protocol: 1. Identify the Claim — What exactly is being stated? 2. Check the Evidence — What proof is offered or missing? 3. Test the Logic — Does the reasoning actually follow? 4. Scan for Assumptions — What's being taken for granted? 5. Consider Alternatives — What else could explain this? 6. After each step, you get immediate feedback explaining why your answer was strong, partial, or off-track. No lectures. No textbooks. Just pattern recognition that transfers to real life.
