Darley and Latane knew they had to prove their theory scientifically so they set up an experiment with college students to test it they divided the students into three groups they took each student to a small building 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 un the building Students in the third group thought that there were four other people in the building AS part of the experiment the person on the TV screen pretended to become ill and called out for help ln the first group where students believed they were the only people in the building 85 percent went to get help for the person ln the second group only 62 percent tried to help. ln the third group only 31 percent tried to help. The results supported Darley and Latane's theory. They figured out that having more withnesses did not mean that help was more likely. ln fact, the opposite was true.
