Interpersonal brain synchronization at frontopolar cortices underlies better advice-taking in groups.

ABSTRACT: We often seek advice from others outside our groups to optimize decision-making. This process may involve discerning the reliability of others, that is, whether the advice others provide is reliable enough to accept. However, little is known about how people collectively take advice from others. In this study, we recruited participant dyads (n = 35) to perform an advice-taking task, where they took advice collectively or individually from unreliable or reliable others. Interpersonal brain synchronization (IBS) was examined using a functional near-infrared spectroscopy-based hyperscanning technique. For advice from unreliable others, the dyads performed better than the individuals. The dyads demonstrated a higher learning rate for bad advice than for good advice, as indicated by the analysi
