Research has shown that eliciting commitment is a valuable way of inciting people to
act, even in emergencies and dangerous situations. The purpose of the two studies
presented here was to explore the relation between the form of commitment used to
prevent a crime and the moderating effect exerted by the number of passive observers
of this crime. At a bus stop, a first confederate put a bag down on the ground upon
arriving and immediately left to withdraw money from an automated teller machine
near the bus stop. Two male participants were present at the bus stop. In Study 1, the
confederate said nothing (control), directly asked one participant to watch his bag
(direct commitment), or asked all present to watch his bag (indirect commitment).
About 30 seconds later, a male confederate walked up to the victim's bag, picked it up,
and quickly walked away in the opposite direction of the victim. A total of 150
participants (50 per condition) were observed. It was found that 34% intervened in the
control condition, 88% in the direct commitment condition, and 56% in the indirect
commitment condition. In Study 2, 150 participants (50 per condition) were observed
while two male confederates were present at the bus stop with the instruction not to
react to the theft. It was found that more intervention was found in the direct
commitment condition (88%) than in the control condition (18%). However, the
indirect commitment condition did not elicit higher intervention (22%). Variation in the
level of personal responsibility to help the victim is used to explain these differences.

Several studies have shown that bystanders' perceived responsibility to act is an
important factor of their own willingness to help the victim of an emergency (see Fischer
et al., 2011; Latan6 & Nida, 1981, for review) and that diffusion of responsibility is
frequently an explanation of non-intervention in dangerous and non-dangerous emergen-
cies. The presence of a passive individual or especially several passive individuals is an
important factor in the decreased perceived responsibility to act. Darley and Latan6
(1968) invited participants into an individual room from which a communication system
enabled them to talk to other participants who were in fact confederates. The participants
were told that a few minutes later, they would take part in a discussion on college life
with the help of an intercom system. During the course of the discussion, one confederate
simulated an epileptic fit. According to the experimental conditions, the group discussion
was composed of two individuals (one participant and one victim), three individuals (one
