Move over, GLM-HMM—there’s a new hidden Markov model in town. In our new preprint, we introduce the DDM-HMM: a model that jointly infers latent decision states from reaction times and choices. Using 24-hour behavioral data from rats, we found that evidence accumulation changes with time of day!

We're looking for a new postdoc to join our team! Do you enjoy conceptualizing, improving, and rethinking empirical methods training for social scientists? Then this job might be for you 😊 Feel free to share among your network and to reach out if you have any questions!

I've been thinking a lot about the foundations of cultural evolutionary theory. While there's been a lot of work on transmission mechanisms, there has been far less work on cultural *selection*. Here's a new working paper presenting a taxonomy of cultural selection processes. osf.io/preprints/so...

New blog just dropped! This one is all about estimators—we cover James-Stein, classical test theory, empirical Bayes, penalized regression, and hierarchical models, showing how they all can be used to do a better job than sample stats alone 🤓 haines-lab.com/post/how-to-...

🚨I couldn’t be happier to share that today I’m officially starting my own research group at the Human Origins Cluster of Excellence in Tübingen (@humanorigins.bsky.social)!🚨We’ll explore drivers of genetic, phenotypic and cultural evolution by integrating evidence from many fields in creative ways 🧬

New paper in TREE co-led w @jennakohles.bsky.social: We explore how resource variability shapes the value of social information for maximizing resource gain & minimizing variance. This eco-evolutionary lens helps us explain why collective sensing emerges in dynamic ecosystems! 🧪 tinyurl.com/2rurcry7

What does it mean for culture to “shape” cognition? In our new TiCS paper, @benjaminpitt.bsky.social & I offer a typology of four possible effects: culture can Privilege one cognitive process over others, Prune out disfavored ones, Produce new ones, or have no effect. www.cell.com/trends/cogni...

Why do otherwise rational people disagree about the same evidence? Our new paper finds that group membership is a deeply rooted influence on how we form beliefs, leading even preschoolers to bias their evidential standards and form inaccurate beliefs. www.nature.com/articles/s41...

as I'm revising my course materials, I keep stumbling upon cool @mc-stan.org developments. Current favorites: 1. your model has funnels and you exhausted reparametrization ideas: metric = "dense_e" makes your HMC learn about covariance btw parameters. Sloooow, but effective! 1/

Very happy to see our ice-fishing paper on the cover of @science.org this week! 🎣🎉 We tracked large groups of Finnish competitive ice-fishers to study how social foragers use social information when searching for resources. 🐟 Link: www.science.org/doi/10.1126/... (contact me for open access)
