ReflectFact: Self-Reflective Agents for Improving Comprehension and Reasoning in Multi-Hop Fact Verification

Aug 13, 2026

Existing multi-hop fact verification methods often suffer from reasoning deviations or erroneous conclusions due to a lack of global objective awareness and conflicts between parametric knowledge and retrieved evidence. To address these issues, this work proposes ReflectFact, a self-reflective agent framework that introduces a three-stage mechanism—explicit reasoning path planning, evidence drift verification, and reflective reasoning validation—to automatically detect and correct positional and substitution biases within reasoning chains for the first time. By integrating multi-hop question decomposition, evidence-grounded re-answering, step-wise consistency checking, and verification chain aggregation, ReflectFact effectively mitigates the misalignment between subtasks and the overarching verification goal. The method achieves state-of-the-art performance, surpassing the strongest baseline by 3.32% on HOVER and 2.78% on EX-FEVER.
