International audienceIn this contribution, we investigate the effects of observation-only and observation with feedback from a third-party, in a one-shot dictator game (DG). In addition to a baseline condition (DG), a third-party anonymous subject is introduced who either silently observes or observes and gives feedback by choosing one of seven messages consisting of varying degrees of (dis)satisfaction.

This complements the literature that argues that altruistic behavior is instrumental in serving other selfish (or non-purely altruistic) ends such as self-reputation or social approval. This experiment contributes to the growing literature aimed at decreasing the artificiality of DG designs, by increasing their practicability and external validit
