A famous experiment was conducted at Princeton University in 1973, in which a group of theology students was asked to walk across campus to deliver a sermon on the topic of the Good Samaritan. As part of the research, some of the students were told that they were late and needed to hurry. Along the route, the researchers Darley and Batson had placed an actor, who was lying on the ground in pain and in need of help. In their haste to give a sermon on compassion, 90% of the "late" students from Princeton Theology Seminary completely ignored the needs of the suffering person. Some of them literally stepped over him.
