Although ethics classes are common around the world, scientists are unsure if their lessons can actually change behavior; evidence either way is weak, relying on contrived laboratory tests or sometimes unreliable self-reports.
尽管伦理课程在全球范围内很常见，但科学家们不确定这些课程是否真的能改变行为；无论哪方面的证据都很薄弱，依赖于人为设计的实验室测试，或者有时不可靠的自我报告。
Perhaps most encouraging of all is a paper from 2022 by researchers at Stanford University that involved a mix of contrived help-seeking interactions and asking people to 16 times they’d sought help in the past.
最令人鼓舞的是斯坦福大学研究人员于 2022 年发表的一篇论文，该论文结合了人为设计的帮助寻求互动和询问人们过去寻求帮助的 16 次情况。
