Exploring the Bystander Effect
Joel E. Dimsdale—
The very public murder of young Kitty Genovese in New York City motivated the next social psychology exploration on the nature of malice. On the night of March 13, 1964, Genovese left work and was walking on a street in Kew Gardens, Queens, when she was chased down and stabbed. The murder was doubly horrific. She didn’t die suddenly; rather, her assailant kept chasing her, stabbing and slashing her over and over again in an attack that lasted more than thirty minutes. She called out in terror: “Please help me! Please help me!” But no one did.
Two investigators, John Darley and Bibb Latané, designed a series of experiments to find out why people do not intervene even in life-threatening situations. If Milgram conducted his studies on the infl uence of authority, looking over his shoulder at Nazi Germany, Darley and Latané wanted to learn what accounts for bystander apathy. Why did no one intervene to save Genovese’s life? Why did so many people stand by and do nothing to save the lives of Nazi victims? It was a topic Hannah Arendt had wrestled with in another context: “Under conditions of terror most people will comply but some people will not. . . . No more is required, and no more can reasonably be asked, for this planet to remain a place fit for human habitation.” Sadly, the number of people who resist complying is small.
To be fair, emergency situations are often sudden, ambiguous, and out of the typical life experience of the beholder. But, as Darley and Latané would learn, there was something about the social environment itself that influences how a person would respond to emergencies. Painstakingly, first at Columbia University and New York University and then at Princeton University, the investigators grappled with this problem in multiple experiments.
Darley and Latané confronted their subjects with a threatening situation and assessed how the subjects would respond. Then, in an ingenious twist, Darley and Latané studied the subject alone or else in small groups. How would a subject respond to an emergency in the presence of other people who appeared to ignore what was happening?
In one experiment, subjects reported to a room to talk about the problems of urban life while smoke poured from the room’s heating register—not just a few puffs, but so much smoke that by the end of the session “vision was obscured in the room by the amount of smoke present.” When subjects waited alone, 75 percent of them quickly reported the smoke, but when they entered a room with two other seated people who studiously ignored the smoke, the subjects’ behavior was strikingly different. Only 10 percent of these subjects reported the smoke even though they “coughed, rubbed their eyes, and opened the window.”
In another experiment, subjects arrived at the lab and were greeted by a receptionist who stood up, drew a curtain, and noisily clambered up on a chair to grab some folders. The receptionist surreptitiously turned on a tape recorder, which played the sound of a loud crash, a scream, and the following script: “Oh, my God, my foot . . . I . . . can’t move . . . it. Oh . . . my ankle, I can’t get this . . . thing . . . off me.” The tape played sounds of weeping and moaning. Here again, the question was simple: Would anyone check on the receptionist, and how long would it take? It may be comforting that 70 percent of the subjects who waited alone checked on the receptionist. It will not be comforting to learn that when the subjects were waiting with a stranger who ignored the receptionist’s plight, only 7 percent of the subjects intervened.
A third experiment revealed even more indifference. In this setting, subjects were ushered into individual cubicles and asked to talk via intercom with other subjects about the problems they experienced in college. One subject, secretly a confederate of the investigators, revealed that in addition to all the usual stresses of college, he was embarrassed because he had a seizure disorder. He then grew increasingly incoherent, saying: “I-er-umI think I-I need-er-if-if could-er-er-somebody er-er-er-er-er-er-er give me a little-er-give me a little help here because-er-I-er-I’m-er-er h-h-having a-a-a real problem-er-right now and I-er-if somebody could help me out it wouldit would-er-er s-s-sure be-sure be good . . . because-er-there-er-er-a cause I-er-I-uh-I’ve got a-a one of the-er sei—-er-er-things coming on and-and-and I could really-er-use some help so if somebody would-er give me a little hhelp-er-uh-uh-uh (choking sounds). . . . I’m gonna die-er-er I’m . . . gonna die-er-help-er-er-seizure-er (chokes, then quiet).”
When subjects were alone in the cubicle, 85 percent got up within a minute to check on the subject who was presumably having a seizure. Subjects were then tested with other people in the same cubicle. If the subject was paired with one person who had been secretly instructed to ignore the situation, 62 percent of the subjects got up to check on the presumably ill student. If however, the subject was tested with four confederates who ignored the apparent seizure, then the chance of the subject responding fell to only 31 percent, and it took such people, on average, three minutes to check on their fellow student.
There have been countless variations on the design, but the inherent message remains the same: in social situations, there is a diffusion of responsibility. If a bystander sees that other witnesses are doing nothing, then he or she will also do nothing—“bystander apathy,” as Darley and Latané put it so pungently.

The description above about the murder of Kitty Genovese is probably inaccurate.
Researchers have questioned this version of events, offering alternative explanations as to why neighbors failed to intervene, and suggesting that the actual number of witnesses was far fewer than reported. In 2015, Genovese’s younger brother, Bill, said that the police were indeed summoned twice but did not respond because they believed it was a domestic dispute, and blames The New York Times for faulty reporting.
After the death of the perpetrator in 2016, The New York Times called their story “flawed”, adding:
“While there was no question that the attack occurred, and that some neighbors ignored cries for help, the portrayal of 38 witnesses as fully aware and unresponsive was erroneous. The article grossly exaggerated the number of witnesses and what they had perceived. None saw the attack in its entirety. Only a few had glimpsed parts of it, or recognized the cries for help. Many thought they had heard lovers or drunks quarreling. There were two attacks, not three. And afterward, two people did call the police. A 70-year-old woman ventured out and cradled the dying victim in her arms until they arrived. Ms. Genovese died on the way to a hospital.”
