Social goodness refers to the behavior that individuals pay attention to, respect and protect the needs and rights of others in good faith in interpersonal interaction. The implementation of social goodness helps to enhance the cooperative behavior of others.In order to test the influence of perceived social goodness on interpersonal decision-making, we set up an interactive game situation between "giver and receiver". Through manipulating social goodness level, trust game, charitable giving and self-reported questionnaire were used to measure the trust level and interpersonal decision-making of the recipients in the process of interaction.The results showed that compared with the low social goodness group, participants in the high social goodness group showed higher levels of trust, higher donations, and better interpersonal impression of the doer.
