It's been 20+ years since researchers recommended that police videorecord lineups. But no one has empirically tested the diagnostic value of these videos... until now.

Here, we provide a compelling case to mandate the videorecording of lineup procedures.

Finding #3:
Witnesses' lineup behavior can diagnose high-confidence mistaken identifications. When witnesses are highly confident but their behavior indicates a weak and disfluent recognition experience, the CJS system should doubt their accuracy.

Finding #2:
Not only did witness behaviors discriminate between accurate and inaccurate decisions, but they also improved classification performance over and above confidence and decision speed.

Finding #1:
Accurate witnesses behaved markedly different than inaccurate witnesses—a strong and fluent recognition experience implied accuracy and a weak and disfluent recognition experience implied inaccuracy.

🚨 New preprint 🚨

Why should police video-record lineups?

We videorecorded 1496 witnesses as they completed lineups. We coded the behaviors that these witnesses demonstrated and subjected the resulting data to machine learning analyses.

Link and findings below!

Why are lineup rejections less diagnostic of innocence than suspect identifications are of guilt?

Take a look at our preprint for insight on this all-too-common finding of the eyewitness id literature.

🚨 New preprint available!

In this paper, we look at why lineups better inculpate the guilty than they do exculpate the innocent (the rejection-inferiority effect).

‼️ Another new preprint ‼️

Here, we find that video recordings of lineup procedures can aid us with diagnosing witness accuracy (over and above confidence and decision time).

This project provides even more evidence that the legal system should mandate video recording lineups.

That’s kinda the idea behind dual process signal detection theory (DPSDT)! DPSDT posits that positive decisions are governed by two processes - recollection and familiarity- whereas negative (rejection) decisions are only governed by familiarity.

These findings contradict recent inferences that in the context of eyewitness lineups, target variability is less than or equal to lure variability and brings models of eyewitness memory in line with longstanding findings from the basic recognition literature!

Rebecca Ying @rying.bsky.social · Jul 29

Here, we examined DPSDT and UVSDT models & found that they were able to account for residual asymmetry (& improved model fit relative to the EVSDT model). These models suggest that the visual recognition system is better at detecting target presence than target absence.

When lineups are modified so that we always get suspect-specific confidence (see prev work on the Rule Out), the rejection-inferiority effect is reduced but not eliminated.

Rebecca Ying @rying.bsky.social · Jul 29

Lineups are a flawed measurement tool. Suspect IDs & confidence directly map on to how well the suspect matches the witness’s memory for the culprit- a good proxy for guilt. Conversely, rejection decisions & confidence often measure memory strength of a filler.

Reviewer notes: That’s a very nice mediation analysis you have there. It would be a shame if something happened to it.

Mediation analysis has gotten a lot of flak, including classic titles such as “Yes, but what’s the mechanism? (Don’t expect an easy answer)” (Bullock et al., 2010), “What mediation analysis can (not) ...

Maya Irvin-Vitela will be presenting this work in the Saturday 3/15 datablitz (5pm-6pm) in San Cristobol. This work is from Ciera Arnett's dissertation (Maya helped as a coder!). Interesting work & findings about psychosis, substance use, & insanity. #APLS2025 #Law #Psychology #PsychLaw #CLJLab

"The Legal Intersection of Psychosis and Substance Use: A Mixed-Methods Investigation of Settled Insanity" by Maya Irvin-Vitela, Ciera Arnett, & Tess Neal of the Clinical & Legal Judgment Lab.

"The current study" slide that details the primary aims of the two studies comprising this work (case-law analysis of settled insanity cases in the U.S., and an experiment with 310 forensic mental health experts as participants). This work was preregistered and materials, data, and code are available on the OSF.

Case Law Review results showing that coders with clinical science training found about 30% of the cases reviewed as having some viability for settled insanity defense from a clinical science viewpoint, contrasted with the actual legal outcome of these cases in which just one case (2% of the sample) actually had a successful settled insanity claim.

Results from experiment with forensic mental health experts, showing that mental health experts generally saw settled insanity as redundant to traditional insanity. Findings across the two studies showed legal and mental health professionals agree that acute, voluntary substance intoxication at the time of a crime generally precludes the use of an insanity defense...but cases where substance use is more distal are more complicated.
