Egg-trading worms start reciprocation with caution, respond with confidence and care about partners’ quality

Abstract Conditional reciprocity (help someone who helped you before) explains the evolution of cooperation among unrelated individuals who take turns helping each other. Reciprocity is vulnerable to exploitations, and players are expected to identify uncooperative partners who do not return the hel...
