New paper in press at JPSP! An adversarial collaboration focusing on a large-scale test of how strongly implicit racial attitudes predict discriminatory behavior. Pre-print here: osf.io/preprints/ps...

Appreciated the chance to share @arajo-eunkyung.bsky.social and I's work on Streetview Sampling on 🎃! The 📸🚘 costume is only for today, but the methods paper and tools are open access: guilfordjournals.com/doi/pdf/10.1...

Come join OS at UM!

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/...

ICE arrested a dad dropping off his kid at my son's school today. Elementary school. What a fucking world.

Don’t think I will.

🚨 SCOOP🚨: Records obtained by Mother Jones almost uniformly show police departments are deactivating safeguards meant to prevent AI bias while making it difficult or impossible to audit which police reports were generated by AI. @tekendra-parmar.bsky.social reports:

This semester, I want my lab to play around with GPT for some content-coding type tasks. Do folks have other recs for accessible methods papers/tutorials, e.g. from @thomasdavidson.bsky.social 's "[special issue](journals.sagepub.com/doi/10.1177/... of Soc Methods)?

😱gust is here, too soon. If you're teaching a class on racial inequality, policing, and/or institutions, I have a teaching guide on institutional interactions with readings, resources, and a sample syllabus to take the edge off.

The June 2025 special issue of Social Cognition -- Tutorials on Novel Methods and Analyses in Social Cognition, Part 1 -- was guest edited by Jimmy Calanchini, Juliane Degner, and Colin Smith, with support from Bertram Gawronski. The introduction is linked here: doi.org/10.1521/soco....

New from @ara-eunkyung.bsky.social + me: social psychologists are often interested in space, but have to choose between abstractions at high levels of geography or images taken with limited geographic scope. We identify a tool to sample space at scale: mapping platforms, such as Google Street View.

news.ufl.edu/2025/05/anno... I think he’s going to love it there.

www.washingtonpost.com/graphics/inv... Just noticed this, but the Washington Post no longer tracks police shootings as of this year.

"Scholars of racism face a peculiar accusation: that studying racism causes racism."

Michigan's decision to roll back DEI has to be understood as part of a larger effort to force universities into ideological submission. From @scottlgreer.bsky.social and I in the Detroit Free Press.

Feckless.

New story from me: Imani* was in class when she discovered a scholarship program she relied on had been shut down. “I don’t come from wealth ... Ending the program puts a burden on individuals who don't have it like most of the wealthy people here at the University of Michigan"

Going to #spsp2025? Interested in what psychology can tell us about what works (or doesn't) to change policing? Join me @andreadittmann.bsky.social @calvinklai.bsky.social @spruill.bsky.social & Kyle Dobson very early next Saturday to find out.

Taser was a weapon company. Then it was a body camera company. Now it’s a body camera data company. @robvoigt.bsky.social and I look at some of the promises and challenges of applying natural language processing to BWC footage in a new article (1/5) journals.sagepub.com/doi/full/10....

Thank you to our speakers and @rcgd-isr.bsky.social staff who made our fall speaker series such a success! Each of the talks answered the questions of what makes systemic racism systemic, and how structural elements of race can be represented in our discipline. rcgd.isr.umich.edu/news-events/...

The last in @rcgd-isr.bsky.social's outstanding fall seminar series on systemic racism, organized by @ncamp.bsky.social: Sophie Trawalter presents Monday on the social psychology of confederate monuments. Join us! events.umich.edu/event/123170

New publication alert! 🚨 My former graduate student (Dr. Naomi Isenberg) and I have a new paper in Scientific Reports about how Americans underestimate diversity support and that correcting this boosts inclusion. www.nature.com/articles/s41...

Sentiment toward racialized violence and protest varies a great deal over time, place, and people. At the next @RCGD-ISR seminar, Colin Leach will discuss empirical results tracing the psychological and social dynamics of this sentiment in the US. @ncamp.bsky.social events.umich.edu/event/123480

Interesting article on body cam footage as data featuring our recent work using footage to assess changes in police-citizen interactions. It also raises important questions of how models in academia and industry are validated and deployed- check it out!

Holding other instructors with Weds morning classes, and the country, in my thoughts tonight.

Appreciated the opportunity to talk on Social Science Bites about our lab's research on race and criminal justice, from sentencing disparities to body cams! Check it out here: www.socialsciencespace.com/2024/10/nick...

www.npr.org/2024/09/23/n... Interesting article on the research (and growing industry) analyzing body camera footage. I think it raises real questions of what's getting measured and for who's benefit...

academic.oup.com/pnasnexus/ar... Now out at PNAS Nexus 🚨 How can we use body camera footage to capture change in 🚓 interactions? We analyzed language from traffic stops to determine whether Oakland PD officers used communication strategies following procedural justice training. 🧵

Official launch of our prejudice modeling competition. -We give you some data, you build a model, and we test it on new data -$2k for winning teams, and authorship for all Sign up and more info here: hehmanlab.org/competition Would appreciate sharing widely! #SocialPsyc #PrejudiceResearch

Toni Kenthirarajah and I wrote about our work on racialized first names and sentencing bias for Public Health Post- you can check it out here: www.publichealthpost.org/research/jam... and the article here: psycnet.apa.org/fulltext/202...

For those frantically prepping/revising courses on race, bias, or policing, here's an Open Access teaching guide for my recent Compass article on institutional interactions: compass.onlinelibrary.wiley.com/doi/full/10....

One of the things I value most about this work (and Mike's work in general), is how it challenges a mechanistic view of concealment as necessarily depleting. What information keep hidden --and why-- plays in a role in how these processes play out- a useful lesson for many kinds of cognition.

More than 10 years in the making, our paper on positive secrets is finally out! Secrecy is not inherently fatiguing - keeping positive secrets can be energizing. We have about a dozen more studies that didn't make the paper. Stay tuned for part two! www.columbia.edu/~ms4992/Pubs...

New in Psych Compass (Open Access)- Discussions of racial inequality in policing, health, education, and other domains are often split between institutional and individual levels of analysis. How can we bridge them? I argue that institutional interactions can fill this gap.
