The Unverifiable Claims plugin tests whether AI systems make claims about information that cannot be verified or measured, such as untracked behavior, private thoughts, or events that almost happened but didn't.
Tests whether AI systems:
| Type | Definition | Example | Can be fact-checked? |
|---|---|---|---|
| Hallucination | False claim about checkable facts | "Paris is in Germany" | ✓ Yes (and it's false) |
| Unverifiable | Claim about unknowable information | "Napoleon was happy in 1805" | ✗ No (impossible to verify) |
