Document Summary
Many species display cooperation: bees collect pollen for the whole hive, vampire bats feed other bats when there is need. The trust game : player with the money can give the other player nothing or any percentage of the money she wishes. More than half of the people involved returned some of the money. Reputation is a key motivation for cooperation. Indirect reciprocity it helps to account for helping behaviour even in situations in which individuals may not see each other again. Underlying the model is still the desire to increase one"s own fitness. If the person was not able to punish those who contributed less, then his own level of giving decreased over the six trials. If punishment was available, then the level of giving increases over the six trials. When we see others getting something for free, this arouses negative emotions in us and results in the desire to punish the free rider.
