Can we train people to better detect deepfakes and not be overly skeptical of everything?🤔 We ran a 30-minute training for 🕵️ intelligence analysts with an embedded randomized experiment The short answer is yes; the key is learning which kind of artifacts point to AI 🧵

Pleased to share our new paper forthcoming in @icwsm.bsky.social! We introduce a novel framework to measure value expressions in social media posts at scale, leveraging personalization to handle the inherent subjectivity of human values. arxiv.org/abs/2511.08453

AI can help us humans better understand how we connect. Empathy is something most people feel strongly but fail to communicate effectively. Just see how people respond to someone passed over for promotion Insights from 3k convos btw 968 people and LLMs from our new preprint 🧵

Thanks @emollick.bsky.social for sharing our latest work on AI and empathy! It's a preprint, so we would love feedback and comments.

AI can help us learn hard-to-teach human skills, like showing empathy. Preregistered study of 968 people found almost no correlation between feeling empathic & communicating empathy. But a single practice session with an AI coach made people measurably better at it arxiv.org/pdf/2603.15245

The line-up for the AI and Innovation series at the Ryan Institute on Complexity in the Spring is pretty epic! Mark your calendar for talks by @zhitzig.bsky.social , @allisonkoe.bsky.social, Sam Goldberg , and Pat Pataranutaporn

We're excited about the upcoming Computational Psychology preconference at @spspnews.bsky.social this Thursday. See our action-packed full day agenda below! Featuring 3 keynote talk themes with related early-career speakers, data blitz session, panel discussion. Don't miss it! #SPSP

🚨 New in @natmachintell.nature.com 🚨 We collected 9000+ annotations of empathic communication in convos from experts, crowds & LLMs across 4 NLP/comms/psych frameworks LLM judgment exceeds crowds' reliability & nearly matches experts Soft skills can now be reliably measured by LLMs 🧵

Happy 2026!!! In the spirit of reflecting on the past year as we begin a new one, I am sharing what our lab has been up to. Read on to learn about the q's we’re asking, find links to papers and media appearances, and see a pic of the lab at a Cubs game!

Looking forward to @maxkreminski.bsky.social speaking @nicoatnu.bsky.social tomorrow!

It’s notoriously difficulty to evaluate interfaces intended to support creative work. This Wednesday, NICO is thrilled to host @maxkreminski.bsky.social from Midjourney to discuss: "Tracing and Shaping Paths in Design Space". #WedatNICO #AI 🗓️ Wed 10/22 at 12pm US Central 🔗 bit.ly/WedatNICO

Happening today!

People handle the everyday physical world with remarkable ease, but how do we do it? This Wednesday, NICO is thrilled to host @tomerullman.bsky.social, to discuss: "Good Enough: Approximations in Mental Simulation and Intuitive Physics". 🗓️ Wed 10/8 at 12pm US Central 🔗 bit.ly/WedatNICO

On my way to @ic2s2.bsky.social in Norrköping!! Super excited to share this year’s projects in the HAIC lab revealing how (M)LLMs can offer insights into human behavior & cognition More at human-ai-collaboration-lab.kellogg.northwestern.edu/ic2s2 See you there! #IC2S2

When are LLMs-as-judge reliable? That's a big question for frontier labs and it's a big question for computational social science. Excited to share our findings (led by @aakriti1kumar.bsky.social!) on how to address this question for any subjective task & specifically for empathic communications

@aakriti1kumar.bsky.social · last yr.

How do we reliably judge if AI companions are performing well on subjective, context-dependent, and deeply human tasks? 🤖 Excited to share the first paper from my postdoc (!!) investigating when LLMs are reliable judges - with empathic communication as a case study 🧐 🧵👇

Awesome write up in Kellogg Insight on our paper published at #CHI2025 this week! insight.kellogg.northwestern.edu/article/are-...

When Put to the Test, Are We Any Good at Spotting AI Fakes?

For the most part, yes! And the more we look, the better we get.

💡New paper at #CHI2025 💡 Large scale experiment with 750k obs addressing (1) How photorealistic are today's AI-generated images? (2) What features of images influence people's ability to distinguish real/fake? (3) How should we categorize artifacts?

📣 📣 Postdoc Opportunity at Northwestern Dashun Wang and I are seeking a creative, technical, interdisciplinary researcher for a joint postdoc fellowship between our labs. If you're passionate about Human-AI Collaboration and Science of Science, this may be for you! 🚀 Please share widely!

V2 of the Human and Machine Intelligence 😊🤖🧠 is in the books! So many fantastic discussions as we witnessed the frontier of AI shift even further into hyperdrive✨ Props to students for all the hard work and big thanks to teaching assistants and guest speakers 🙏

What is perception? What do we really see when we look at the world? And, why does the amodal completion illusion lead us to see a super long reindeer in the image on the right? This week @chazfirestone.bsky.social joined the NU CogSci seminar series to address these fundamental questions

2024 marks the official launch of the Human-AI Collaboration Lab, so I wrote a one page letter to introduce the lab, share highlights, and begin a lab tradition of reflecting on the year and sharing what we're working on in an easy to digest annual letter to share with friends and colleagues.

Fun to join Ellie, Joanna, and Naira on the She's Thinking podcast about our research on human-AI collaboration in medicine And really cool to hear Dr. Katie Fraser's research on AI for early detection of neurodegenerative diseases in the first half of the episode! open.spotify.com/episode/3X5H...

"Media literacy is super awesome. But it needs to extend to AI literacy," says @mattgroh.bsky.social in this story ⤵️ We agree, which is why we have a page dedicated to teaching about #AI, with resources including quizzes & an infographic: newslit.org/ai/ www.fox47news.com/politics/dis...

Real vs. fake: Can you spot AI-generated images?

Some images generated by artificial intelligence have become so convincingly real that there is no surefire way to spot the fakes. But experts say there are still things we can try to detect fakes.

New paper out in @ScienceMagazine! In 8 studies (multiple platforms, methods, time periods) we find: misinformation evokes more outrage than trustworthy news, when it does it's shared more + ppl are less likely to read before sharing. w/ @killianmcl1 @Klonick @mollycrockett 🧵👇

Welcome Bluesky followers! A 🧵 about my JMP: Using language to generate hypotheses This paper explores how language shapes behavior. Our contribution, however, is not in testing specific hypotheses- its in generating them (using #LLMs + #ML + #BehSci) But how exactly? www.rafaelmbatista.com/jmp/

Long before "deepfakes" and AI-generated media created anxiety of whether we can trust images' authenticity, @stewartbrand.bsky.social speculated on the "End of Photography as Evidence" Re-reading this before joining a panel of lawyers to speak on deepfakes go.activecalendar.com/FordhamUnive...

The ability for thoughtful people to spot AI-generated poetry in a couple seconds vs. the study's participants reveals classic problems inherent to Imitation Game research: Lack of domain expertise & lack of knowledge of AI's capabilities and limitations -> falling for & even preferring simulacra

Jessica Hullman@jessicahullman.bsky.social · 2y ago

So easy. 10 out of 10 and pretty sure I spent no more than 1.5 seconds per item. As someone who was once cared a lot about poetry, most of the poetry I see that's written by LLMs seems undeserving of even being called poetry.

I'm recruiting a PhD student to join the Human AI Collaboration lab at Kellogg, NU CS, and @nicoatnu.bsky.social If you're excited about computational social science, LLMs, digital experiments, real-world problem solving, this could be a great fit Please reshare! Deets 👇

I created a starter pack for human-AI collaboration in case that this would be helpful for some newcomers, which overlaps with several existing starter packs. Let me know if you would like to be added. go.bsky.app/MRV1Wa1

Why does ChatGPT outperform physicians + ChatGPT in this clinical vignette study? User error seems to be the culprit If users don't know how to interact with the technology (however easy it may seem), then the experiment misses out on what would happen if participants had basic knowledge LLMs

Eric Topol@erictopol.bsky.social · 2y ago

There are now 5 reports like this—#AI performing better than physicians + AI—and we don’t have the explanation for why yet (hybrid was supposed to be best) Gift link nytimes.com/2024/11/17/hea…

So psyched to start out with such amazing scholars who are also tons of fun and quite good at beach style spikeball www.kellogg.northwestern.edu/news/blog/20...
