this singular, quite current event.”

Common sense suggests that out of thirty-
eight people, at least one should have had the “moral fiber” to at least pick up
the phone and call 911. Paradoxically, however, Darley and Latané found that
it was precisely because there were thirty-eight people listening to what had
happened that no one came to Genovese’s aid. The task of responding to her
plight was shared by a large number of people—a factor Darley and Latané
call the diffusion of responsibility—and everyone seems to have assumed that
someone else would do something.

Setting out to test this hypothesis—which
they originally hammered out at an all-night party at which the topic of
Genovese was being discussed—Darley and Latané set up an experiment
which, like much other social psychological research of the time, involved a
large measure of deception.
Rather cleverly, they led students to believe that they were involved in
group discussions about personal problems, such as the difficulty of adapting to
university life.

Because talking about such problems can be embarrassing,
these naive subjects were led to believe that they were talking to other students
sitting in separate cubicles via an intercom. In reality, these naive subjects
were listening to tape recordings of other students acting out roles in the
“discussion.” Sometimes the subjects were told that they were involved in one-
to-one discussions with only a single person, sometimes there were supposedly
three people involved, sometimes four, and so on, but in all cases they were
actually only listening to pre-recorded tapes. The first recording, moreover,
was always the same: it was the voice of a student that tells of the stress he is
undergoing at university and the fact that he suffers from epileptic fits. In
reality, this was of course a student acting out the part (interestingly the voice
was that of Richard Nisbett, then a graduate student at Columbia University
and in later life a leading situationist and attribution theorist).

After a short while, the voice of the student on tape would begin to sound
frantic and incoherent, as Nisbett convincingly played out the part of some-
one having an epileptic seizure. Of the subjects involved in the one-to-one
condition—that is, where the naive subject thought that he or she was the only
person around who could help—an impressive 85 percent reported the seizure
immediately and sought help. However, when the subject was led to believe
that he was in a discussion with five other people, only 31 percent sought the
assistance of the experimenter. Quite simply, the presence of others had
socially inhibited the subjects in the latter condition from acting to assist the
person supposedly in distress.
A few years later, Darley and Batson conducted an even more fascinating
experiment by using divinity students to test the theory of the bystander effect,
again using a classic piece of deception.

In this study, the students were given
the task of preparing a sermon on the parable of the “Good Samaritan,” in
