What is happening underneath?
Changing the standard of proof after someone meets it.
The requested proof is provided, then the standard moves farther away. The finish line has wheels.
How to tell
- The standard changes after it is met, especially without acknowledging the original ask.
Why people use it
- It lets someone look reasonable while refusing to be persuaded.
How to combat it
- Say: "Before I answer the new standard, did the first evidence meet the first request?"

- Bad-faith political debates use shifting standards to keep opponents permanently auditioning for legitimacy.
