The experiments placed subjects in an artificial situation where a minor emergency event was taking place and correlated their response to the actions of actors within the experiment room. To test this hypothesis, researchers used undergraduate students and divided them into four groups: a low cohesive group with two people, a low cohesive group with four people, a high cohesive group with two people, and a high cohesive group with four people. In some cases of high ambiguity, it can take a person or group up to five times as long before taking action than in cases of low ambiguity. The bystander effect describes situations in which a group of bystanders witness harm being done, yet do nothing to help or stop the harmful activity.
