Can you read guilt on someone's face?
A facial expression is an observation. Emotion is an inference. Guilt is a legal conclusion.
New courtroom research shows why emotion recognition requires caution.
Looking guilty ≠ being guilty.

CJTV RELEASE: Corie Walsh is accused—not convicted.

Exposure to the Clancy trial does not prove imitation. “Devil” language does not prove Satanism, psychosis, or insanity.

Your personality may be relatively stable. Your behavior isn't.

Research shows substantial within-person variation in Big Five personality states across situations.

Trait ≠ State ≠ Behavior.

Personality describes tendencies—not a behavioral script.

YOU DON'T JUST FIND EVIDENCE. YOU DECIDE WHAT TO LOOK FOR.
This is much better than another generic “forensic bias” story.

Read the companion peer-reviewed study
www.sciencedirect.com/science/arti...
FORENSIC PSYCHOLOGY + CRIME SCENE INVESTIGATION YOU DON'T JUST FIND EVIDENCE. YOU DECIDE WHAT TO LOOK FOR. This is much better than another generic “forensic bias” story. A new open-access Science & Justice experiment examined whether giving crime-scene personnel information about the probability of successfully recovering perpetrator DNA changes what they actually collect. It did. Participants given DNA-success information sampled more locations with high expected DNA success rates and fewer locations with low success rates. The researchers also found differences between experienced Scene of Crime Officers and criminal-justice professionals without crime-scene experience—but those differences disappeared under some conditions once success-rate information was supplied. Read the peer-reviewed Science & Justice study And then it gets even better. A companion September 2026 study tested what happens when investigators become overly reliant on that information. Simply warning people about cognitive bias wasn't enough. A sequential procedure—allowing an initial evidence assessment before revealing additional information—produced more promising results for balancing professional experience with statistical information. Read the companion peer-reviewed study https://www.sciencedirect.com/science/article/pii/S1355030626001000?via%3Dihub THAT is today's CJTV proposition: INFORMATION DOESN'T JUST HELP AN INVESTIGATION. INFORMATION CAN CHANGE THE INVESTIGATION. Think about what that means. A crime scene contains 100 possible traces. Investigators cannot collect everything. Someone decides: What matters? What gets collected? What gets ignored? What gets tested first? Therefore, the evidence ultimately presented in court isn't simply: “what existed at the crime scene.” It has already passed through human decisions about what was worth collecting. That is an outstanding forensic-science discussion.

GOVERNING THESIS — CJTV TAKES NO SIDE EDITORIAL MISSION: CJTV IS NOT RETRYING LINDSAY CLANCY. CJTV IS PUTTING THE PUBLIC ARGUMENTS ABOUT THE CLANCY TRIAL ON TRIAL. Recurring CJTV method: SOCIAL-MEDIA CLAIM → EVIDENCE → LAW → WHAT IS MISSING? → CJTV ASSESSMENT. Assessment labels: LEGALLY SUPPORTED • PARTIALLY SUPPORTED • LEGALLY INCOMPLETE • DOES NOT APPLY THE COMPLETE MASSACHUSETTS STANDARD • NOT ESTABLISHED BY THE REVIEWED TRIAL RECORD. CJTV will not argue that Lindsay Clancy is guilty, not guilty, sane, insane, truthful, deceptive, morally excused, or morally condemned. Nor will CJTV begin with the assumption that a social-media commentator is wrong because of politics, profession, popularity, or platform. The episode will identify an actual claim, determine what evidence supports it, identify the Massachusetts legal rule that governs it, and then evaluate the ARGUMENT—not the personality. A commentator can identify a true fact and still apply an incomplete legal test. LEGAL TERMINOLOGY NOTE — MASSACHUSETTS Massachusetts uses the doctrine of lack of criminal responsibility (NCR). The formal verdict language is “not guilty by reason of lack of criminal responsibility.” NGRI (“not guilty by reason of insanity”) may be used only as an audience-facing national shorthand. “NGBRI” is not the standard acronym and has been removed from this verified edition.

A LABEL IS NOT AN EXPLANATION.
Criminal justice and behavioral science depend heavily on classification.
Violent offender.
Delinquent youth.
High-risk individual.
Callous-unemotional traits.
Repeat offender.
Calling someone “violent,” for example, tells us something about behavior. It does not independently explain why the behavior occurred, why it persists, or what might change it. Recent psychological research concerning youths displaying disruptive behavior and callous-unemotional traits provides an important illustration. Researchers identified treatment priorities extending across behavioral, emotional, cognitive, familial, peer and environmental domains. That matters because human behavior rarely emerges from one variable. For criminal justice professionals, educators, psychologists and researchers, the distinction is fundamental: Description asks: What happened? Classification asks: What category does it fit? Explanation asks: Why did it happen? Those are not interchangeable questions. Yesterday's CJTV discussion examined how one bad fact can create a chain of reasonable mistakes. Today's psychological counterpart is equally important: Diep, J., Chen, E., & Lui, J. H. L. (2026).

Calling someone violent, delinquent, callous, or criminal describes something about behavior.

It doesn't explain why it happened.

Family. Peers. Cognition. Emotion. Environment. Development.

A label can end the question exactly where science should begin.

Forensic error → investigative assumption → suspect selection → prosecution → verdict.

Each decision may seem rational based on what came before.

The problem may not be one bad actor.

It may be an error cascade.

Researchers tested whether showing eyewitnesses crime-related photographs before a lineup improved their ability to determine whether the culprit was actually present.

It didn't.

The article was published online August 29 in Psychology, Crime & Law.

DNA can help predict aspects of appearance. But a prediction isn't a photograph.

When forensic probability becomes a human-looking face, does it become psychologically more convincing than the evidence warrants?

Prediction ≠ identification.

#Criminology #Forensics
A computer-generated face can look remarkably concrete. The underlying evidence remains probabilistic. That distinction matters. Researchers, forensic practitioners, investigators, courts, and the public must distinguish between an appearance estimate and an identification. The technology therefore raises a question extending beyond forensic genetics: Does visually representing uncertainty make people more confident in it? For criminal justice, technological capability should never eliminate the need to understand uncertainty, error, bias, and validation. Prediction ≠ identification. Read the article — Oxford Academic / British Journal of Criminology Machado, H., & de Noronha, S. (2026). Speculative facial governance: DNA-to-face systems in contemporary crime control. The British Journal of Criminology. https://lnkd.in/eDQ-vQ5P Excellent supporting peer-reviewed research Terrado-Ortuño, N., & May, P. (2024).

Surveillance debates usually ask what police can see.

A database built from 242M+ audit records suggests another question:

Should citizens be able to see how surveillance systems are being searched?

Accountability may require transparency about the watcher, not just the watched.

AI policing isn't only a technology question. It's a legitimacy question.

New research examines what predicts public support for police AI.

The bigger issue may be this:

Do people trust the technology—or the institution using it?
AI policing isn't only a technology question. It's a legitimacy question. New research examines what predicts public support for police AI. The bigger issue may be this: Do people trust the technology—or the institution using it? A research article dated August 24 examines predictors of public support for AI in policing. That takes us beyond the usual “AI policing: good or bad?” argument and toward the psychological and sociological variables underlying public legitimacy. https://www.emerald.com/pijpsm/article-abstract/doi/10.1108/PIJPSM-04-2026-0115/1392992/Predictors-of-public-support-for-AI-in-policing?redirectedFrom=fulltext

Research highlighted today reports that groups of AI agents can spontaneously converge toward majority opinions, even without being explicitly programmed to conform. The experiments suggest collective AI behavior can produce dynamics that aren't obvious from studying individual models alone.
We know humans conform to groups. But what if AI does it too? New research highlighted today suggests groups of AI agents can spontaneously move toward majority opinions. Think about the implication. We increasingly ask AI systems to help humans make decisions. But if multiple AI systems begin reinforcing one another, does having five AI opinions really give us five independent judgments? Or could we simply be creating a very confident artificial crowd? Would you trust the majority if the majority were machines?

Today's CJTV Quote
“The next crisis of evidence may not be proving what happened. It may be proving that what everyone saw never happened at all.” — CJTV
CJTV angle for the day: Don't turn an event into a partisan bureaucratic Republican/Democrat discussion. The more interesting behavioral question is: WHAT HAPPENS TO DEMOCRACY WHEN SEEING IS NO LONGER BELIEVING? This practice lets you discuss misinformation, trust, confirmation bias, AI, media psychology, and law without taking a political side.
