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.

🚨 New preprint

Excited to share new work led by Raluca Rilla, showing how cheap, open agents threaten online data collection and how open-text analysis beyond conventional traps can help mitigate this threat.

🚨 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.

🚨 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.

🚨 New preprint

Do LLMs have stable dispositions measurable using instruments designed for humans?

Led by @jelenameyer.bsky.social, our new preprint shows that LLM responses are driven by response bias, rendering their psychological profiles method artifacts.

🚨 New preprint 🚨

Excited to share a new preprint led by @zakashussain.bsky.social.

We review how large language models compare to humans in behavior and representations. Our conclusion: LLM cognition is not simply human-like or non-human-like. It is jagged.
