[In an experiment recently cited,] students at Princeton Theological Seminary were asked to go to a nearby chapel and give an extemporaneous sermon on the Biblical parable of the Good Samaritan. As they walked to the chapel, they passed a man slumped in a doorway, moaning for help. About two-thirds of those who thought they had plenty of time stopped to help, but only 10 percent of the students who thought they were late did so.
