Existing pipelines either train detectors on labeled data or leverage Large Language Models (LLMs) for their reasoning ability. However, current approaches remain either limited in generalizability or prone to over-commitment to persuasive yet flawed rationales, lacking systematic experience and mechanisms to expose subtle reasoning errors. We propose \textbf{RoE-FND} (\textbf{\underline{R}}eason \textbf{\underline{o}}n \textbf{\underline{E}}xperiences FND), an LLM-based framework that combines self-reflective experience building with deliberation through retrieved experiences for FND. RoE-FND builds an experience bank via reflective learning that compares an unconstrained analysis with a label-conditioned analysis using the ground-truth label as posterior supervision, then summarizes their critical divergence into reusable reasoning guidelines. During inference, RoE-FND generates two opposing deductions via a flipped pseudo-label provided as posterior, retrieves the most relevant experiences for resolving their key disagreement, and adjudicates the better-supported rationale as the final prediction. Experiments across five popular benchmarks, including text-only datasets, i.e., CHEF, Snopes, PolitiFact, and multimedia datasets, i.e., FakeTT, FakeSV, demonstrate that RoE-FND outperforms strong baselines without optimizing LLM parameters on dataset distributions, while exhibiting strong cross-dataset generalization.
