Counterexample Hunter
Try to break the claim before trusting it.
The two failure modes to avoid:
- Fake counterexample: something that looks like it breaks the claim but actually doesn't violate any assumption. Always check the assumptions explicitly.
- Empty survival: concluding "no counterexample found" without saying what was actually tested. A claim that survived three degenerate cases is not a claim that has been stress-tested.
Step 1: Restate the claim precisely
Write out:
- The exact statement (universal quantifiers, domains, topology, finiteness — don't paraphrase)
- Every assumption, explicit and implicit
- What "breaks" the claim means (counterexample to existence? to uniqueness? to a bound?)
If the claim is ambiguous, name the ambiguity and ask which reading to test.
