Evidence and Causal Reasoning in Criminal Psychology

Criminal psychology requires a defensible connection between observations, psychological explanations, and decisions about an individual. This conceptual article examines how that connection can be made without treating a diagnosis, personality score, or coherent narrative as proof of criminal conduct. Chapter 1 of the source manuscript provides the organizing problem. A focused narrative examination of methodological and forensic literature is combined with an original framework for documenting competing hypotheses. The analysis distinguishes description, association, mechanism, prediction, and legal attribution. Its central proposition is that the quality of a formulation depends on the visibility of its inferential steps and its exposure to disconfirming evidence. An evidence matrix is proposed for recording source dependence, temporal relevance, alternative explanations, and revision conditions. A prospective evaluation design would compare conventional reports with reports using this matrix on completeness, disagreement, and decision consequences. These proposals have not been empirically validated. The article concludes that methodological transparency is a practical research target and a safeguard against unwarranted individual inference
