In real or fictional criminal interrogation scenes, you’ve probably seen the approach where police barge in and confront the suspect with the evidence, trying to get them to crack and give a confession. In this talk, Maria Hartwig and Christian Cory explain why that doesn’t work well, and why a strategic use of evidence (SUE) approach, involving planning out the reveal of evidence, gets much better results. Maria is a well known researcher and trainer of criminal interviewing, and Christian is a 26 year law enforcement veteran. I talk to them about their and others’ attempts to promote more science-based approaches to interviewing and interrogation. They are Co-Directors at the Aletheia Project (project-aletheia.org), which brings together researchers and law enforcement practitioners to improve interview techniques. We talk about their view that “old school” interrogations are built around a misguided “confession obsession,” why bad ideas and exaggerated claims about nonverbel behavior and lie detection are so persistent and popular, and the downsides of lying to suspects about evidence. We talk about what the science really says about micro-expressions, and we explore why people seem so drawn to false, exaggerated ideas about reading behavior.
