Stop Hallucinations Forever

Production-grade hallucination prevention via citation-or-refuse + admit-uncertainty + claim triage.

THE MINDSET SHIFT
Models don't hallucinate because they're lying. They hallucinate because their training rewards 'sounds plausible' over 'I don't know.' Your prompt is what inverts that incentive — for ONE inference, you make uncertainty cheaper than confidence.

Cronbach's 1955 construct-validity framework still applies: an answer can be CORRECT without being RELIABLE. A model can show its reasoning, cite sources, sound confident, and be wrong — because for high-stakes factual claims the difference between knowing and pattern-matching is invisible from inside the forward pass. The model genuinely doesn't know which of its outputs are grounded and which are plausibly confabulated.

The production fix is to OPERATIONALIZE uncertainty. Three techniques stack: (1) the citation-or-refuse rule — every factual claim must point to a specific source, or it doesn't go out; (2) the [UNVERIFIED] tag — make uncertainty explicit and machine-extractable so humans can triage; (3) the "what would change my answer" question — the model's introspection here is actually useful for surfacing the load-bearing assumptions.

The deepest insight: the goal is not to make the model never wrong. That's not possible. The goal is to make the model never CONFIDENTLY wrong. A claim flagged [UNVERIFIED] that turns out to be incorrect is a learning opportunity. A confident citation to a non-existent statute is a liability — sometimes a literal one.
