Joshua Greene, a philosophy graduate now working in psychology who has recently moved from Princeton University to Harvard, studied how people respond to a set of imaginary dilemmas. In one dilemma, you are standing by a railroad track when you notice that a trolley, with no one aboard, is heading for a group of five people.
最近，一些特别的研究提出了关于直觉反应在道德推理中的作用的新问题。乔舒亚·格林，一位刚从普林斯顿大学转到哈佛大学进行心理学研究的哲学硕士，研究了人们如何对一组想象中的困境做出反应。在一种困境中，你站在铁轨边，看到一辆空无一人的电车正驶向前方的五个人。如果电车继续在现有的轨道上行使，他们将会被撞死。
