The Result: Over 1/3 (32%) of the subjects would answer incorrectly if they saw that three others in the classroom gave the same wrong answer. Even when the line was plainly off by a few inches, it didn't matter. One in three would follow the group right off the proverbial cliff.
The Result: The people who had been studying the Good Samaritan story did not stop any more often than the ones preparing for a speech on job opportunities. The factor that really seemed to make a difference was how much of a hurry the students were in. In fact, if pressed for time, only 10 percent would stop to give any aid, even when they were on their way to give a sermon about how awesome it is for people to stop and give aid.
