A hybrid decision framework for evaluating psychometric evidence.
The United States Supreme Court in Daubert v. Merrell Dow Pharmaceuticals (1993) directed federal trial judges to preliminarily evaluate the scientific bases of proffered expert evidence. This article presents a decision flowchart for evaluating psychometric data, and attempts to operationalize existing evidentiary standards in hybrid (part science/part law) terms. The resulting framework should better assist courts and forensic experts to understand, evaluate, and apply scientific reasoning in determining the admissibility and probative value of psychometric evidence.
