Very happy to share that our large-scale experiment (~500k people in 23 countries) where we test a simple descriptive norms intervention to increase vaccine acceptance, is finally published in @NatureComms!https://t.co/bdBoecSAsh pic.twitter.com/kBreUq2n6u
Excited to present our joint work with Jad Sassine and @deaneckles today @icwsm: “influence of repetition through limited recall” - modeling a situation that arises with repetition of ideas and messages in feeds https://t.co/5lWFxVRVUp

With Jan Hązła, @jababi, and Elchanan Mossel, we show NP-hardness of approximating beliefs and computing actions in popular models of Bayesian social learning. Forthcoming in Operations Research: https://t.co/CxQo7lu5T3
