New report led by @robvoigt.bsky.social analyzing NYPD body cam footage. As part of the federal monitorship of the NYPD, we analyze language in over 6,000 BWC recordings to identify under-documented stops and how officers request consent to search. (1/6)

RCGD's symposium is this Friday! Social and computational scientists: Join is to explore new methods for studying complex social and cultural processes. With Rachael Jack, Shinobu Kitayama, @davidjurgens.bsky.social and Alexander Rodríguez. Repost, RSVP, and join us: events.umich.edu/event/152402

Happy SESP eve for those who celebrate! If you are at the conference, come by our session on institutional interactions! @cydneydupree.bsky.social , Nao Hagiwara, Greg Walton, and I will share what interactions can tell us about people and their institutional contexts (🚔🎓🏥).

Looking forward to the conversation at today's @umisr.bsky.social ISR Insights series!

Another example of how discretionary traffic stops are about not so much about the traffic as they are about the discretion.

Someone who knows more than me, I imagine most file storage on OSF is skewed: stimuli (esp. video) can take up a ton of room compared to most (but not all) datasets. Couldn't OSF limit storage size or filetype? Or is the cost of maintenance prohibitive? Either way 🫡 and 😔

COS is announcing important changes to the Open Science Framework (OSF). OSF Projects—used for project collaboration, file mgmt, & storage—is being phased out as an active workspace over the next 6 months. This change does not affect persistence & accessibility of existing public projects. (🧵1/2)

The full report is available here. Together, it builds on our past work, showing how body camera recordings can serve as data to understand policing and a tool to improve it. Thanks to @robvoigt.bsky.social and team, along with the NYPD, monitor, and city of New York (6/6)

These models can sort properly documented stops from non-stops with 90% accuracy. They are 70%+ accurate in IDing under-documented stops. Model-assisted auditing could uncover 50% of undocumented stops ID'd by the monitor by looking at the top 25% "stop-like" recordings logged as non-stops. (3/6)

Second aim: how do NYPD officers request consent to search? Officers are instructed to give + get explicit consent, but words "consent" & "search" only appear in 3% of consent search BWC vids. (4/6)

Our group (@robvoigt.bsky.social, @ncamp.bsky.social , Dan Sutton, & Jennifer Eberhardt) had two aims. First, could BWC transcripts identify pedestrian contacts that crossed the line into stops? @robvoigt.bsky.social trained a classifier on retired federal judges' and the monitor's judgments. (2/6)

New in JSI (OA): Reckless speeding or tinted windows? We look at racial disparities in reasons why drivers are stopped, their disparate impacts on community trust, and how police departments exacerbate —or mitigate— their impacts through policy. (1/7) spssi.onlinelibrary.wiley.com/doi/10.1111/...

Because they entail so much choice, however, police departments can rein in discretionary stops. We found one directive in which merely advised officers to curtail equipment stops reduced racial gaps in stop rates, by bringing down the high number of equipment stops of Black drivers (6/7)

We should make police interactions more respectful. However, enforcement is an investigatory tool, it undermines these goals. Interactions can’t build trust if they start with a lie. As traffic stops become the vehicle for investigation and immigration enforcement, the costs will be severe. (7/7)

Looking across a range of agencies, we find that stops of Black drivers are much more likely to be for minor offenses relative to Whites, particularly in urban police departments. Statewide agencies, focus on enforcement rather than investigation, show no disparities in discretionary context (4/7)

academic.oup.comLeveraging body-worn camera footage to assess the effects of training on officer communication during traffic stopsAbstract. Can training police officers on how to best interact with the public actually improve their interactions with community members? This has been a

This context means different things to Black and White drivers. We asked DMV customers to listen to recordings of equipment + moving stops and report their trust in the officer. White participants were generally trusting, but Black customers were skeptical of officers in high-discretion stops. (5/7)

Psychologists (including me) have thought about how officers talk with citizens, and the benefits of making stop interactions more respectful. But, a narrow focus on what goes on during stops overlooks the decision that leads to those stops in the first place (2/7). academic.oup.com/pnasnexus/ar...

Every driver is breaking some traffic law at some time. However, officers have more choice in enforcing some offenses (broken taillight) than others (drunk driving). Minor stops are ambiguous: all the more so since police are permitted and encouraged to use them as a pretext for investigation. (3/7)
