Definition
Interdisciplinary research brings together methods, theories, and findings from multiple disciplines to address problems that no single discipline can adequately frame. Forensic psychology is inherently interdisciplinary: its core questions span psychology, law, criminology, sociology, statistics, neuroscience, and increasingly data science and computer science.
True interdisciplinary work goes beyond multidisciplinary parallel play (different specialists analysing the same problem from their own lanes) to genuine integration — joint research designs, shared theoretical frameworks, and methods that draw on multiple traditions simultaneously. It is harder to do well and harder to publish, but produces findings none of the contributing disciplines could reach alone.
Why it matters
Where it shows up
Interdisciplinary forensic centres — like the International Research Centre for Investigative Psychology, or US Criminal Justice schools combining criminology, psychology, and law — produce the most consequential field-defining work. Cross-disciplinary training programmes, joint funding schemes, and shared databases (the FBI's NamUs, the UK's HOLMES2) further enable integration.
