The sharing economy is fueled by trust, which allows strangers to cooperate. To share responsibly, one needs to be aware of the various consequences sharing has on interacting and third parties. When transparency about such consequences is lacking, mutual trust among interacting parties may encourage people to cooperate and share, in turn, creating unintended negative impacts. Psychologists have long studied trust and cooperation, yet few insights from psychological science have been used to understand the sharing economy. Here, we propose that evoking trust may paradoxically increase motivated information processing leading people to share irresponsibly by ignoring the negative consequences sharing has on others. We review three conditions under which evoking trust may lead to irresponsible sharing: ethical blind spots, willful ignorance, and misinformation. We propose that transparent information is key to enable and encourage responsible sharing. More psychological research is needed to better understand how this flourishing, trust-based industry can be shaped to encourage safe, cooperative, and responsible sharing.

共享经济是由信任推动的，它允许陌生人合作。要负责任地分享，需要了解分享对互动和第三方的各种后果。当此类后果缺乏透明度时，互动各方之间的相互信任可能会鼓励人们合作和分享，进而产生意想不到的负面影响。心理学家长期研究信任与合作，但很少有心理学的见解被用来理解共享经济。在这里，我们提出，通过忽略分享对他人的负面影响，唤起信任可能会自相矛盾地增加积极的信息处理，导致人们不负责任地分享。我们回顾了唤起信任可能导致不负责任分享的三种情况：道德盲点、故意无知、和错误信息。我们建议透明的信息是实现和鼓励负责任分享的关键。需要进行更多的心理学研究，以更好地了解如何塑造这个蓬勃发展的、以信任为基础的行业，以鼓励安全、合作和负责任的分享。
