Beyond Eyeball Tests: A Methodical Rebuttal to Fillon et al.'s Commentary

In our original study, “Consumed by Creed” (Adam-Troian & Bélanger, 2024), we established significant and consistent associations between obsessive-compulsive disorder symptom severity and radical intentions across four distinct U.S. population samples—Environmentalists, Republicans, Democrats, and Muslims—partially or fully mediated by obsessive passion. Fillon et al. (2024) challenged our findings, alleging methodological errors and an excessive degree of researcher flexibility, which they claim could lead to false-positive results. In this response, we critically examine Fillon et al.'s commentary, arguing that it exemplifies flawed meta-scientific critique. We demonstrate that their approach relies on a series of unsupported and misleading claims, including a misinterpretation of the literature, unjustified reliance on visual data inspection, speculative assumptions about religious influences on our findings, and a shifting of the burden of proof. Through rigorous re-analyses, we reaffirm the robustness of our original results and address the unfounded allegations regarding our methodological practices. We also critique Fillon et al.'s approach, highlighting the necessity of domain-specific expertize in meta-scientific evaluations and cautioning against the risks of speculative and defamatory criticism in academic discourse. This exchange underscores the importance of maintaining rigorous standards in both original research and its critique, ensuring that scientific debate remains grounded in evidence rather than conjecture.
