This, in turn, can cause a tragedy of the commons,[18] where selfish behavior lead to the depletion of resources, with long-term negative consequences for the group. However, in natural bee and wasp societies, only 0.01%-0.1% and 1%, respectively, of the workers lay eggs, suggesting that strategies exist to combat cheating to prevent tragedy of the commons.[13][18] These insect systems have given scientists opportunities to study strategies that keep cheating in check. Such strategies are commonly referred to as “policing” strategies, generally where additional costs are imposed on cheaters to discourage or eliminate cheating behaviors.
