Human cooperation by lethal group competition
Why humans are prone to cooperate puzzles biologists, psychologists and economists alike. Between-group conflict has been hypothesized to drive within-group cooperation. However, such conflicts did not have lasting effects in laboratory experiments, because they were about luxury goods, not needed for survival ("looting"). Here, we find within-group cooperation to last when between-group confli...
متن کاملBetween-group competition and human cooperation
A distinctive feature of human behaviour is the widespread occurrence of cooperation among unrelated individuals. Explaining the maintenance of costly within-group cooperation is a challenge because the incentive to free ride on the efforts of other group members is expected to lead to decay of cooperation. However, the costs of cooperation can be diminished or overcome when there is competitio...
متن کاملCooperation and between-group competition
Introducing competition between groups may induce cooperation to emerge in defection games despite considerable cost of cooperation. If the groups can confine themselves to a cooperative sector, either by providing incentives to raise the cooperation level in one group, or by providing disincentives so that the cooperation level in the other group gets lowered to match that of the first, maximu...
متن کاملWithin-group competition reduces cooperation and payoffs in human groups
Social organisms in many taxa cooperate to produce resources that are shared among group members. Some cooperatively produced resources may be monopolized by individuals who invest in within-group competition, but these have largely been overlooked in empirical and theoretical research on human cooperation, which has focused on noncontestable public goods. In this study, we allow for the potent...
متن کاملBetween-group competition, intra-group cooperation and relative performance
We report the results of a new public goods experiment with an intra-group cooperation dilemma and inter-group competition. In our design subjects receive information about their relative individual and group performance after each round with non-incentivized and then incentivized group competition. We found that, on average, individuals with low relative performance reduce their contributions ...
