Forensic psychologists working in criminal court must be prepared for their opinions, methods, reports, and testimony to be tested through adversarial cross-examination. Unlike clinical practice, where the focus is often treatment, support, and therapeutic alliance, criminal forensic assessment requires a disciplined approach to data collection, psycholegal reasoning, bias management, and communication under pressure. For forensic psychologists upskilling their practice, cross-examination should not be viewed solely as a threat. It can also clarify what makes an assessment defensible: transparent methods, careful reasoning, structured decision-making, clear report writing, and testimony that remains grounded in the data’s limits.
