Happy to share our latest study published in PNAS.
Using data from 274,316 French students, we find that lower-SES students are less likely to wait for better university offers, even when waiting would lead to more prestigious or better-fit programs.

😍 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

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.
