Abstract

Recently, some unusual research has raised new questions about the role of intuitive responses in ethical reasoning. 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. They will all be killed if the trolley continues on its current track.
