Mutual aid must remain equitable or helpers are judged as poor partners

Evidence

Mutual aid is no less constrained by fairness principles than strict reciprocity. If people want to treat others in a mutually advantageous way, they need to share the costs and benefits of mutual aid equitably. This means that the help given and the help received (when either situation arises) must be of comparable value. People who think that it is appropriate to hold the door for someone who is less than two meters away from it and who act accordingly have every reason to expect others to do the same – provided that they have equal chances to be the one holding the door (one cannot, for instance, ask people whose office is close to the door to always open the door for others). This means also that individuals can’t ask others to do more than what they are ready to do themselves, and that they may depart from being seen as optimal partners if they provide help well beyond set mutual expectation – for instance, by holding the door for someone who is 10 meters away, thereby sending the wrong signal that this is what they would expect when the roles are switched. — Nicolas Baumard, A mutualistic approach to morality, 101

  • SEED: The door-holding-at-10-meters example is a strikingly concrete illustration of signaling excess generosity as a bad partner signal — could anchor a short piece on how over-helping is socially costly.
