To address these challenges, we propose a communication model that:
- clarifies intent through dialogue
- guides claims toward verifiable evidence
- explains diverse expert perspectives instead of forcing consensus

It reframes medical fact-checking as patient–expert dialogue

Verifying medical claims wasn’t straightforward for experts. They struggled with:

1️⃣ linking claims to evidence
2️⃣ interpreting underspecified or misguided claims
3️⃣ labeling nuanced claims—often with disagreement

These challenges are inherent to end-to-end fact-checking 🚧

We study real-world medical claims from Reddit, preserving post context and verifying them with RCT abstracts. 📄
Six experts annotated 20 claims, each with 10 abstracts.

Annotations span:
1️⃣ abstract relevance
2️⃣ claim-level evidence quality
3️⃣ explanations citing abstracts

Are we fact-checking medical claims the right way? 🩺🤔

Probably not. In our study, even experts struggled to verify Reddit health claims using end-to-end systems.

We show why—and argue fact-checking should be a dialogue, with patients in the loop
