The ultimatum game involves trust and the belief in reciprocity. Many players choose to reject a low offer not because it is rational, but because they want to punish the proposer for making an unfair offer. This is based on the expectation that if they accept the unfair offer, the proposer will do the same in the next round. Thus, players may choose to reject an offer even if it means they receive nothing, in order to signal to the proposer that unfair offers will not be tolerated.
