Dr. Vance conducted an investigation into the bystander effect. He staged a minor accident (a dropped folder of papers) in a busy corridor. In one condition, there was only one bystander present; in the other condition, there were five bystanders present. Dr. Vance recorded whether the key bystander helped retrieve the papers or walked past without helping.
