Sharing our latest endeavour here. How reproducible is your paper? @philipjakobbln.bsky.social and I built rigor.me to ease the burden of computational reproducibility. If you provide a paper, data and code, we execute it and tell you what works (and what fails). Beta is available now: rigor.me

🌞 The Summer Institute on Bounded Rationality @mpib-berlin.bsky.social returns next week. At its core, we ask: how do minds make good decisions under genuine uncertainty by drawing on an adaptive toolbox of simple heuristics tuned to their environment? www.mpib-berlin.mpg.de/research/res...

😍 Our latest is out now in @commspsychol.nature.com. 🤩 We show with Bayesian modelling and experimental manipulation of uncertainty that developmental differences in social influence depend on differences in the internal uncertainty people have about their choice doi.org/10.1038/s442...

Internal uncertainty impacts social information use in risky choice across adolescence - Communications Psychology

Adolescents’ choices are influenced by others. A social risky choice experiment and Bayesian modelling reveal that age differences in internal uncertainty, being unsure how to choose, relate to differences in susceptibility to social influence.
