# Card 4: The Detective

**Reach for it when** the answer is smooth but wrong, and you can't yet point to the sentence at fault.

**Say it like this**

- "Don't give me a new conclusion yet. Walk back through your steps and find the first one where the thinking went wrong."
- "The mistake is in step two, where you assumed costs stay flat. Keep step one. Rebuild from step two."

**Not this:** "Wrong. Try again."
