Trust is based on both rational considerations (outcomes and expectations) and moral considerations (respect for moral norms). We find that social proximity shifts the extent to which trust is perceived as a moral decision. People are more likely to trust similar strangers (partners they share personality traits with) because they feel it is the moral thing to do. In three studies, we found that partner similarity was associated with increased trust, and this effect was mediated by increased feelings of normative obligation. This mediation remained significant after controlling for expectations of reciprocity and participants' tendency to like similar partners more than dissimilar partners (Studies 1 and 2). Furthermore, the felt obligation to trust similar partners was based, in part, on a desire to avoid insulting the other party's moral character. The effect of partner similarity on feelings of obligation was weakened when distrust was no longer insulting to the trusted party's character (Study 3). These findings add to our knowledge of how social information shifts the extent to which trust is perceived as a moral decision.

信任困境中的社会接近度和对规范的尊重

信任基于理性考虑（结果和期望）和道德考虑（尊重道德规范）。我们发现社会亲近度改变了信任被视为道德决定的程度。人们更有可能信任相似的陌生人（与他们有共同性格特征的伙伴），因为他们认为这样做是道德的。在三项研究中，我们发现伴侣的相似性与信任的增加有关，这种影响是通过规范义务感的增加来调节的。在控制了互惠期望和参与者喜欢相似伙伴的倾向后，这种中介仍然很重要（研究 1 和 2）。此外，信任类似伙伴的感觉义务部分是基于避免侮辱另一方的愿望。l 道德品质。当不信任不再侮辱受信任方的性格时，伴侣相似性对义务感的影响就会减弱（研究 3）。这些发现增加了我们对社会信息如何改变信任被视为道德决定的程度的了解。
