===== Methodological Overreach ===== '''Methodological overreach''' refers to the inappropriate extension of a study’s methodology beyond what the data or design can reliably support. It occurs when researchers: * Make claims that exceed the limitations of the study design (e.g., causal claims from observational data). * Apply complex statistical or machine learning tools without adequate justification or validation. * Generalize findings to populations or clinical settings not represented in the data. * Use sophisticated methods (e.g., SHAP, deep learning) to add perceived value without improving scientific rigor. ==== Examples in clinical research ==== * Using a cross-sectional dataset to build a tool for **longitudinal prediction**. * Claiming **preventive or therapeutic impact** from an observational model. * Presenting **model performance metrics** (like AUC) as proof of clinical utility. ==== Consequences ==== * Misleading conclusions * False sense of confidence in tools or interventions * Poor translation into real-world clinical practice '''In summary:''' methodological overreach undermines scientific integrity by overstating what a study can truly demonstrate.
