Recursive Deductive Verification: A framework for reducing AI hallucinations
:
I've been working on a systematic methodology that significantly improves LLM reliability. The core idea: force verification before conclusion.
The Problem:
LLMs generate plausible-sounding outputs without verifying premises. They optimize for coherence, not correctness.
RDV Principles:
Never assume - If not verifiable, ask or admit uncertainty
Decompose recursively - Break complex claims into testable atomic facts
Distinguish IS from SHOULD - Separate observation from recommendation
Test mechanisms first - Functions over essences, reproducible behavior over speculation
Intellectual honesty over comfort - "I don't know" is valid
Practical Results:
Applied as system instructions, RDV significantly reduces:
Hallucinations (model stops instead of confabulating)
Logical errors (decomposition catches flaws)
Unjustified confidence (verification reveals gaps)
Example:
Without RDV: "The best solution is X because Y" (unverified assumption)
With RDV: "What are we optimizing for? What constraints exist? Let me verify Y before recommending X..."
Implementation:
Can be added to system prompts or custom instructions. The key is making verification a required step, not optional.
This isn't about restricting capability - it's about adding rigor. Better verification = more reliable outputs.
Open question: Could verification frameworks like this be built into model training rather than just prompting?
