New postdoc position at Cornell! This is a bit of a unique one: It's a teaching postdoc focused on integrating active learning strategies into psychology courses (including one of my own). Should be a lot of fun!

Can AI simulations of human research participants advance cognitive science? In @cp-trendscognsci.bsky.social, @lmesseri.bsky.social & I analyze this vision. We show how β€œAI Surrogates” entrench practices that limit the generalizability of cognitive science while aspiring to do the opposite. 1/

First paper from my lab out @commspsychol.nature.com

www.nature.com/articles/s44271-025-00275-w

Latent factor models are popular for mental representation of people, e.g. warmth & competence

But we show in naturalistic contexts, more complex representations are needed: high-dimensional networks

Also I want to note, this commentary was inspired by one of my recent favorite papers, β€œArtificial intelligence and illusions of understanding in scientific research” by @lmesseri.bsky.social and @mjcrockett.bsky.social

Would definitely recommend giving that a read if you haven’t already!!!

Abstract: Scientists across disciplines increasingly rely on artificial intelligence to scan, summarize, and interpret research articles. While these tools offer speed and clarity, their perceived effectiveness exposes deeper, systemic issues in science. Specifically, we argue that the popularity of AI highlights two key problems: the historical failure to communicate research clearly, and the persistent overestimation that other scientists fully understand published research. Rather than an isolated trend, AI use reflects how academic writing often excludes more than it informs. Here, we trace how institutional norms, training, incentives, and culture reinforce AI reliance, and outline reforms to promote more inclusive, comprehensible science.

Excited to share my latest paper, now out in Science Communication!!

TLDR: We’ve seen the (valid) warnings about using AI to understand science, but where does this reliance come from? Perhaps it reflects the longstanding failure to communicate science clearly.

🚨 New study reveals that when used to summarize scientific research, generative AI is nearly five times less accurate than humans.

Many haven't realized, but Gen AI's accuracy problem is worse than initially thought.

As grant money starts drying up, it's more important than ever not to waste it on paying publishers' open access "article processing fees" when we can host PDFs for free. Tom Morgan and I wrote a paper on this, forthcoming at Science and Public Policy. Accepted draft here: osf.io/preprints/os...

Exclusive: NSF stops awarding new grants and funding existing ones US science funder also plans to screen grant applications for compliance with β€˜agency priorities’.

πŸ””BREAKINGπŸ””

The NSF has frozen all research grant awardsβ€”cutting off life-saving science midstream and demanding ideological screenings for future funding.

This is censorship disguised as oversight.

Can confirm that my NSF grant "How False Beliefs Form & How to Correct Them" was cancelled today because it is "not in alignment with current NSF priorities" Shocking that understanding how people are misled by false information is now a forbidden topic.
