They put him or her in a room with a TV screen that showed another person in a different room in the building; then they left. Students in the first group thought that they were alone in the building. Students in the second group thought that there was one other person in the building. As part of the experiment,the person on the TV screen pretended to become ill and called out for help. In the first group, where students believed they were the only people in the building. 85 percent went to get help for the person. In the second group, only 62 percent tried to help. In the second group, only 31 percent tried to help. The results supported Darley and Latane’s theory. They figured out that having more witnesses did not mean that help was more likely. In fact, the opposite was true.
