Abstract:
Fear can undermine cooperation. It may discourage individuals from collaborating with others because of concerns about potential exploitation; prompt them to engage in defensive aggression by launching a preemptive strike; and propel power-seeking individuals to act dominantly rather than compassionately. Therefore, accumulated evidence requires a more contextualized consideration of the link between fear and cooperation in adults.
