In a recent thought-provoking study, @benjwagner.bsky.social & co claim that behavioural signatures attributed to context-dependent RL “are very well explained by habit-like action repetition”. I obviously disagree and this thread explains what evidence backs my belief (thread 👇) 1/n

Prakhar, in a recent thought-provoking paper and thread, boldly claimed that the learning-rate biases may be mere “statistical ghosts” of decaying learning rates We took up the challenge and put this claim to the test. Here are our findings (w/ @romanececchi.bsky.social). 1/n osf.io/preprints/ps...

Genuine Learning Biases Persist After Accounting for Temporally Decreasing Learning Rates: insight from fitting six datasets.

Recent claims suggest that learning-rate asymmetries observed in human reinforcement learning may be artefactual, arising from a failure to account for temporally decreasing learning rates in Bayes-optimal agents. Here, we re-analyzed six datasets and found that models incorporating learning biases systematically outperformed both Bayes-derived and decay-based models, and that learning biases persisted even when temporal decay was explicitly included. These results demonstrate that temporally decreasing learning rates cannot account for learning asymmetries, which instead emerge as robust and reproducible features of human reinforcement learning.

Lucky for you, lazy people at #RLDM2025, two of the best posters have apparently been put side-by-side: go check @maevalhotellier.bsky.social and @constancedestais.bsky.social posters!
