LESSON 3 · Build an Airtight Argument
The Weekly Audit
Motivated reasoning is the engine behind most hidden fallacies. You start with the conclusion you want, then build a case for it, and mistake that building for honest discovery. It feels like you reasoned your way there. You didn't; you arrived first and argued backward.
A short weekly review catches it. Pick one decision or argument you made and ask:
- Did I look for evidence against my view, or only for support?
- Did I take the opposing case at its strongest, or knock down its weakest version?
- What evidence could have changed my mind? If none, was I reasoning or just defending?
