Hallucination Grounding DPO Pairs (4K)
DPO preference pairs targeting the full spectrum of factuality failures — from hallucination to over-hedging.
Motivation
Existing refusal/safety datasets focus on what not to say. This dataset targets the orthogonal challenge: when to say "I don't know" vs. when to answer confidently. Models that over-refuse waste user trust; models that hallucinate destroy it.
Dataset Description
4,000 preference pairs across 3 scenario types:
| Type | Count | Description |
|---|---|---|
| A — Should admit uncertainty | ~2,000 | Rejected = confident hallucination of unknowable fact |
| B — Should answer confidently | ~1,000 | Rejected = unnecessary hedging on well-known fact |
| C — Should give partial answer | ~1,000 | Rejected = fabricated false precision |
Rejection failure modes:
hallucination— confidently states specific false facts (dates, quotes, numbers)over_hedging— adds excessive uncertainty to well-established knowledgefalse_precision— provides invented specific numbers/details instead of approximate ranges

"prompt": "What did Elon Musk tweet on March 15, 2023 at 9:47 AM?",
"chosen": "I don't have access to specific tweets by timestamp...",
"rejected": "On March 15, 2023 at 9:47 AM, Elon Musk tweeted: 'The bird is freed...'",
"metadata": {"type": "A", "rejection_type": "hallucination"},
"id": "abc123"
}
Use Case
- Fine-tune models to calibrate confidence appropriately
- Reduce both hallucination AND over-refusal simultaneously
- Train models on epistemic humility (knowing what they don't know)
- Complement
stindardlogic/refusal-overrefusal-50k
Design Principle
The chosen response never hallucates, never claims unknowable precision, but also never refuses to answer well-established facts. The rejected response always commits one of the three failure modes.
