The Tenth Man in the Room: What Four Centuries of Red Teaming Teach Investigators and Leaders
Spies gather intelligence, but someone still has to decide—usually without certainty. From the Prussian war game to the Catholic Church's Devil's Advocate, Israel's "Tenth Man," and the red teams that stress-tested the bin Laden raid, history shows that the most dangerous moment in any investigation isn't when the file is thin and everyone's arguing. It's when the file feels complete and everyone agrees. Are you red teaming your case—or one unchallenged assumption from disast

Science-Based Interviewing: Free, Open-Access Research Every Investigator Should Know About
Science-Based Interviewing puts investigators back in control by grounding interviews in peer-reviewed research rather than intuition, tradition, or pseudoscientific lie detection. This article shows where to find open-access research on interviewing, interrogation, memory, deception, and false confessions—allowing investigators to read the evidence for themselves, verify claims, reduce investigative risk, and strengthen decision-making through transparent, evidence-based pra

Child Abuse Investigations: Follow the Evidence
How can we tell whether a child died from co-sleeping or if she was smothered intentionally by a parent who had tired of her crying? How can we tell if the story parents gave about a broken leg or a brain bleed is plausible? We lean on child abuse specialist pediatricians, especially in physical abuse cases, to help us solve these and other quandaries. These skilled physicians are invaluable members of the multidisciplinary team (MDT). I consult with our local specialists on

Detective Days: Exploring Wensley's Impact and Historical Significance in Criminal Investigation (Free eBook)
Frederick Porter Wensley’s career at Scotland Yard offers enduring lessons for modern Criminal Investigation. Long before formal models or buzzwords, Wensley understood that information is the lifeblood of every case. His success came from patience, careful listening, and respect for evidence, not tricks or rigid systems. That same philosophy underpins today’s science-based approach: gather reliable information, avoid contamination, and seek understanding before conclusions.

The Science Behind Memory Distortion: Implications for Investigators
Investigators rely on memory as evidence, yet memory is vulnerable to distortion through post-event information and poorly framed questions. Research on the misinformation effect shows how leading questions, social influence, and timing can alter recall. Science-Based Interviewing (SBI) protects memory integrity by prioritizing early interviews, witness separation, free narratives, and the strategic use of evidence to gather accurate, reliable statement evidence.

The High-Value Detainee Interrogation Group (HIG): History, Research, and Lessons for Science-Based Interviewing & Interrogation
The High-Value Detainee Interrogation Group (HIG) serves as a critical interagency effort within the U.S. government, bringing together intelligence professionals, operational interrogators, and academic researchers to advance the science and practice of interrogation. Established in 2009 under the direction of Barack Obama, the HIG was created to ensure that interrogation practices are effective, ethical, and grounded in empirical research. Since its creation, the HIG has su

False Confessions: A Look into What They Are and Their Historical Context
False confessions are not rare anomalies. They are predictable outcomes of coercive, accusatory interviewing and pseudoscientific lie-detection practices. This article examines the history, psychology, and risk factors behind false confessions and their role in wrongful convictions. It contrasts confession-driven interrogation with Science-Based Interviewing, an evidence-based approach that prioritizes reliable information, corroboration, and sound questioning to reduce inves

When Confidence Becomes a Liability: Confirmation Bias and Science-Based Interviewing
Confirmation bias is predictable—but not unavoidable. Left unchecked, it distorts interviews, weakens investigations, and jeopardizes outcomes. Science-Based Interviewing (SBI) offers a practical path forward by using red teaming to challenge assumptions, test hypotheses, and counter confirmation bias and other cognitive errors. Through structured critical thinking, SBI strengthens objectivity, protects case integrity, and supports ethical, evidence-driven decision-making.
