Our paper on human creativity and LLMs has been (cond.) accepted to #CHI25! It's been humbling to see the preprint spark conversations beyond academia (one TikTok discussing it gained 40k likes, link in thread). Excited to connect with creativity researchers at the conference!
Human Creativity in the Age of LLMs Randomized Experiments on Divergent and Convergent Thinking "Our findings reveal that while LLM assistance can provide short-term boosts in creativity during assisted tasks, it may inadvertently hinder independent creative performance when users work without assistance, raising concerns about the long-term impact on human creativity and cognition." by @1harsh_kumar J. Vincentius, E. Jordan, @ashton1anderson ๐Ÿ“– arxiv.org/pdf/2410.03703

As AI becomes an active participant in our cognitive lives, the line between thought partner and substitute is becoming harder to maintain. time.com/article/2026/04/30/โ€ฆ

New paper: "In Your Own Words"! We propose a computational framework for identifying interpretable themes from free-text survey data, and demonstrate its benefits on a new dataset of self-described race, gender, and sexual orientation. ๐Ÿงต1/

New #CHI2026 paper led by @JiayinZhi0728 that I'm grateful to be part of! Most AI cognition research assumes sufficient time. But real life? We're either rushing at the last minute or spiraling over a project due next year. Time context changes how AI impacts our thinking.
โœจNew paper alert Does AI help or harm critical thinking? Itโ€™s one of the most pressing questions around AI. But maybe the better question is: under what conditions? In our #CHI2026 paper, we find that time can change everything. ๐ŸŒ criticalthinking-ai.app/ #AI #criticalthinking #humancognition #decisionmaking #civicparticipation (1/10)

We were doing positive results on AI in education before positive results on AI in education was cool: dl.acm.org/doi/abs/10.1007/9โ€ฆ
๐Ÿšจ๐Ÿšจ Excited to share our first *positive* results on AI in education! Most AI tutor work focuses on making the chatbot better. We suggest another lever: deciding what students should practice next to improve learning. We combine an LLM tutor with reinforcement learning to personalize problem sequencing using signals from student-chatbot interactions and solution attempts. We tested this in a 5-month randomized field experiment in a Python course across 10 high schools in Taipei. All students had the same course material and the same AI tutor. The only difference was adaptive vs. fixed problem sequencing. Result: across 770 students, adaptive sequencing improved performance on an in-person final exam taken without AI assistance by 0.15 SD, with larger effects for beginners. Our evidence suggests the gains came from stronger engagement and more productive AI use.

What if we boost LLM output diversity by fusing base and aligned models? Excited to share this work led by @YichenZW, whose passion for understanding LLM diversity really shows here. More insights and fun ideas on LLM creativity coming soon as well!๐Ÿ’ก
Lack of diversity in your LLM generation? (also noted by Artificial Hivemind, best paper @NeurIPSConf) Time to bring your base model back! An inference-time, token-level collaboration between a base and an aligned model can optimize and control diversity and quality!

My big problem with low-powered studies is that CONDITIONAL on obtaining a significant result, the estimate is often exaggerated or the wrong sign, which misleads entire subfields for years. Doubt it? Run a simulation.

A subtle aspect of predictive modeling is target variable construction: translating an unobservable concept like "healthcare need" into a prediction target But how does target variable construction unfold in practice, and how can we better support it going forward? #CSCW2025๐Ÿงต

Curious how repeated interactions with ChatGPT are affecting your creativity? Do LLMs boost or hinder our ability to innovate later on without assistance? If you're researching the impact of LLMs on human cognition, don't miss my #CHI2025 talk tomorrow (Wed), 5:08 PM JST!
