Women still exit psychological research at a disproportionate rate. Tracking 80k researchers, our new article maps the gender attrition gap and shows that differences in performance, networks, and institutions explain only part of it. psycnet.apa.org/doi/10.1037/... arxiv.org/abs/2510.13273

🚨 Out now in TICS How can language models help cognitive science? @ruimata.bsky.social & I outline 5 uses: mapping research fields, formalizing theories, cleaning up constructs & measures, predicting behavior across tasks, and capturing environmental variation. 🔗 doi.org/10.1016/j.ti...

🚨 Now out in PNAS In decision research, "talk is cheap." We show it isn't. Using LLMs to analyze participants' free-text explanations of their choices, we find verbal reports are a rich, scalable window into how people actually decide. 🔗 www.pnas.org/doi/10.1073/... Led by Kamil Fulawka
