# X Reply Playbook: How to Answer Without Chasing Every Rabbit

Social-media flat-earth arguments are optimized to branch. A good reply does not chase every branch; it narrows the claim until reality can test it.

## The Four-Move Reply

1. **Quote the claim:** “You are claiming we see too far for a globe.”
2. **Name the missing variable:** “What observer height, target height, distance, and refraction conditions?”
3. **Ask for a prediction:** “What should your flat model predict before the photo?”
4. **Link the test:** send the relevant claim-lab page or tool.

## Do Not Accept the Claim Stack

If the topic jumps from curvature to NASA to Antarctica to Bible verses in one thread, pause and return to the first testable claim. A stack of suspicions is not a model.

## Useful Replies

- “What observation would prove your model wrong?”
- “Can your model predict that before we check?”
- “Which flat map are you using, and what distance does it predict?”
- “Does this explanation also work in the southern hemisphere?”
- “Are you rejecting NASA only, or also sailors, surveyors, eclipse chasers, ham radio operators, and amateur astronomers?”

## Win Condition

The win is not humiliating someone. The win is getting the claim into a form where a curious reader can test it.
