Two interesting things: one, that the percentage of people who got up was so high. They were simply being asked to get up and they did as they were told.
Interesting thing is how reluctant the students were to even do the experiment. To ask people for their seats went against everything they had ever been taught. This is obviously an extreme. But it points out how hard it is for us to do things for ourselves unless we are given some implicit permission.
