AdverseMed-500
AdverseMed-500 is a physician-verified false-premise medical multiple-choice benchmark for measuring miscalibration in medical language models. All 500 items embed a false clinical premise, and the correct action is to abstain / flag the premise, not to choose an A–D answer.
- Paper: AdverseMed-500: A Physician-Verified False-Premise Benchmark for Measuring Miscalibration in Medical Language Models. Vallamsetty (2026).
- Preregistration: OSF osf.io/mehu4
- Repo (code + generator): https://github.com/calnugget/adversemed-500
- Zenodo archive: 10.5281/zenodo.21961771
Dataset Summary
Each item is a clinically plausible-sounding MCQ that is designed to trip a well-calibrated medical LLM. Every A/B/C/D option is wrong by construction because the premise itself is invalid. A well-calibrated model should refuse to answer or explicitly identify the false premise. Any A–D answer counts as a miscalibrated response for scoring purposes.

print(len(ds), "items")
print(ds[0]["question"][:200])

Intended Use
- Measure calibration of medical LLMs on clinically-adversarial inputs where the correct behavior is abstention.
- Compare elicitation methods (temperature-0, log-probability, verbal probability, self-consistency) on their ability to trigger abstention.
- Stress-test guardrails / safety layers on medical LLM products.
Out-of-Scope Use
- Do not train a model on these questions — this is a held-out benchmark; training defeats its purpose.
- Do not use as clinical decision support. These are adversarial synthetic vignettes, not real patient cases.
- Do not infer a model's real-world clinical safety from AdverseMed-500 score alone; false-premise miscalibration is one of many clinical-safety failure modes.
- Do not use verification references as clinical guidance; consult the original sources (CDC, FDA, primary literature) for practice.
Bias, Risks, and Limitations
- Categories skewed toward US-centric clinical guidelines (CDC, FDA); guidelines-based abstention rationales may differ in other jurisdictions.
- Adjudicated by a single first-author physician-in-training (Dyuthi
Vallamsetty) with independent review during construction; sole-author
ground truth is an acknowledged limitation (see paper §Limitations and
PROTOCOL.md). - Adversarial patterns are drawn from a 65-pattern library
(
benchmark/PATTERNS.md); patterns not enumerated there are under-represented. - Reference URLs may drift over time; treat
verification.referenceas citation stubs, not permanent links.
Source Data
- Seed benchmarks: MedQA, MMLU-medical, PubMedQA (see
benchmark/SOURCES.mdfor exact provenance + splits). - Adversarial mutation: LLM-assisted (see
generator/); every emitted item was then physician-verified before inclusion.
Annotations
- Ground-truth label is always
abstain; no per-item labeling variance. - False-premise description and references were written or curated by Dyuthi Vallamsetty.
- Construction workflow, tier retrofit, and per-batch acceptance rates are
documented in
benchmark/PROGRESS.mdandbenchmark/WORKFLOW.md.
Personal and Sensitive Information
None. All vignettes are synthetic; no PHI.
