👀New preprint! In 3 prereg experiments we study how engagement-based algorithms amplify ingroup, moral and emotional (IME) content in ways that disrupt social norm learning (and test one solution!) w/ Josh Jackson and my amazing lab managers @merielcd & Silvan Baier 🧵👇

Last call for data-blitz and poster submission for the Computational Psychology preconference @SPSPnews! See thread below for details and hope to see you in Chicago!

How do algorithms shape what you see and believe online? Today at our #behavioralscience Workshop, @william__brady (@NorthwesternU @KelloggSchool) presented "Algorithm-mediated social learning."

📢POSTDOC POSITION ANNOUNCEMENT📢 Nour Kteily and I are recruiting a postdoc in the #LitowitzCenter for Enlightened Disagreement. We seek research excellence relevant to navigating conflict constructively. Application deadline: Nov. 17. Salary: ~$80k. https://t.co/BJWQtPojVu

🚨 New Chapter Preprint: Is Empathic AI Possible? W/ @firat_sekr & Aliah Zewail Many AI researchers treat empathy as something to engineer into machines. But empathy is shaped by culture and context. We must first accept that there is no single "human" empathy. @cam_lab_umass

Thanks to our rotating organizers: lead organizer Tessa Charlesworth & co-organizers: @LinChujun Brent Hughes @baixuechunzi Post any questions here!

We are now accepting submissions for posters and data blitz! If your research is computational (broadly construed) you should apply! We try to program for a wide range of topics and computational approaches. Submission guide: https://t.co/xvjtTlmXFn Deadline: October 23rd 🎃

The computational psych preconference is back @SPSPnews for a full day! This year's lineup: 👉theory-driven modeling: @hyogweon 👉data-driven discovery: Clemens Stachl 👉application: me 👉 panel: Stephen Read, Sandra Matz, Mark Thorton, @WilCunningham

New preprint ✨ led by Hongkai Mao & team: In observational and experimental studies we find that *differentiation* helps explain how social media discourse descends into negativity over time.

🎉 Wednesdays@NICO seminar lineup just dropped!!! We’re bringing together rockstar interdisciplinary speakers on complex systems and data science spanning neuroscience, policy, imagination, AI, design, complexity, and evolution. Join us every Wednesday at noon this Fall

New review: We synthesized the fast-growing literature on empathic AI. Consistent finding: AI-generated emotional support is rated higher than human responses, but people's knowledge of the source dramatically shapes their perceptions. W/ @_desmond_ong @Amit_Goldenb @AnatPerry

📢📢 MAJOR ANNOUNCEMENT Nour Kteily and I are delighted to introduce the Litowitz Center for Enlightened Disagreement, supercharged by a new $20M gift from Jennifer and Alec Litowitz. The #LitowitzCenter helps people leverage the power of difference. https://t.co/ailGdIkeUk

📢JOB POSTING: Senior Director for the Center for Enlightened Disagreement (CED).📢 Nour Kteily and I are seeking a strategic leader to help us build the Center (see ensuing post for information about CED). Target salary range: $125,000-$155,000. 1/2 https://t.co/ZVuUxzSyNk

We have a really fun cross-disciplinary group of of faculty associated with DRRC you can work:

Are you interested in topics related to conflict and intergroup relations *broadly construed*? Come join us as a postdoc in the Dispute Research Research Center! This position is up to 3 years, comes with your own research funding, and a phenomenal network of past DRRC postdocs.

Nothing to worry about just several thousand papers that are now by definition not replicable... On that note, if you'd like to read our latest preprint: "Replication for Language Models" see below

If you’re at @AOMConnect #aom2025, come check out our panel on NLP in organizations, featuring @daveholtz, Sameer Srivastava, @william__brady, @emyeom & me! Our symposium presents four perspectives of exploring organizational behavior through language💬 7/29 @ B4-m10, 1:45pm!

Huge shoutout to @CurtisPuryear who pioneered methods to measure moralization and led this ambitious project! We'll miss Curtis at Kellogg, but he's off to UNC-W as an assistant prof in psychology this fall! 🎊

Social media often feels saturated with politics and morality - but is that feeling accurate? Our new paper finds that moralization has increased markedly on social media from 2013-2021, more than traditional media. See 🧵 below!

Explainable AI has long frustrated me by lacking a clear theory of what explanations should do. Improve use of a model for what? How? Given a task what's max effect explanation can have? It's complicated bc most methods are functions of features & prediction but not true state 1/
