Abstract
Leaders can launch hostile attacks on out-groups and organize in-group defence. Whether groups settle the conflict in their favour depends, however, on whether followers align with leader's initiatives. Yet how leader and followers coordinate during intergroup conflict remains unknown. Participants in small groups elected a leader and made costly contributions to intergroup conflict while dorsolateral prefrontal cortex (DLPFC) activity was simultaneously measured. Leaders were more sacrificial and their contribution influenced group survival to a greater extent during in-group defence than during out-group attacks. Leaders also had increased DLPFC activity when defending in-group, which predicted their comparatively strong contribution to conflict; followers reciprocated their leader's initiatives the more their DLPFC activity synchronized with that of their leader. When launching attacks, however, leaders and followers aligned poorly at behavioural and neural levels, which explained why out-group attacks often failed. Our results provide a neurobehavioural account of leader-follower coordination during intergroup conflict and reveal leader-follower behavioural/neural alignment as pivotal for groups settling conflicts in their favour.

Abstract
Abstract
Bermúdez argues for rational framing effects based on normatively appropriate quasi-cyclical preferences. We suggest that this argument conflates preferences over specific outcomes with preferences over outcome aspects. Instead of implying quasi-cyclical preferences, framing affects decisions through standard economic trade-offs. Nonetheless, we demonstrate that framing can affect behavior through altering perceptions of particular outcome aspects when framing effects are not decomposable.
