The bystander effect: What is it, and is it real?

Oct 15, 2019

What is happening inside the minds of people who fail to act when they see someone else in distress? We explore the theory behind the ‘bystander effect’.

We all like to think we would be the one to step up if we saw someone in trouble; and people who have witnessed traumatic events often feel guilt about the inability to act. But psychological conditioning usually takes over in such situations, and when people do fail to act, it’s not necessarily because they made a conscious choice to abandon their fellow human beings. In fact, most of the time, it’s a result of something that psychologists describe as the ‘bystander effect.’

Why does the bystander effect occur?

The bystander effect describes a phenomenon whereby people become less likely to act in an emergency if there are others present. According to Psychology Today: “The greater the number of bystanders, the less likely it is for any one of them to provide help to a person in distress.”

This could be put down to two factors:

  • Diffusion of responsibility: Each individual believes that one of the other people present will act.
  • Group think: People assume that if no one else is responding, that means a response is not necessary. Humans instinctively monitor those around them to assess societal expectations.

Aside from that, there’s the confusion such situations create. The people present aren’t entirely certain what is going on, and are therefore more likely to follow someone else’s lead.

According to Stephanie Preston, a professor of psychology at the University of Michigan, the bystander effect is not unique to humans. She points to an experiment in which a group of rats were given the opportunity to help a fellow rat. The researchers found that introducing an unfamiliar rat into the group caused a spike in stress hormones among the other rats, and made them less likely to act.

The bystander effect experiment: Where there’s smoke…

…there may or may not be fire, depending on how the other people in the room react. This is what an experiment performed by Bibb Latane and John Darley revealed. They divided participants up and had them sit in a room and fill out questionnaires; some of the participants were alone in the room, some were in groups of three, and some were in a group of three where two members of the group were actually members of staff pretending to be participants.

Smoke was pumped into the rooms while the participants filled out questionnaires. In 75% of cases where the participant was alone, they reported the smoke. In cases where it was a group of three, only 38% reported the smoke. And finally, in cases where there were two members of staff posing as participants (and instructed not to react to the smoke), only 10% of the participants reported the smoke.

Catherine ​Genovese, and the history of the bystander effect

The textbook example of the bystander effect is the murder of Catherine “Kitty” ​Genovese , which occurred soon after midnight on13 March 1964. 28-year-old Catherine was attacked as she arrived at her apartment entrance in Queens, New York; and though there were around a dozen people in the nearby apartment block, none of them answered her repeated cries for help. Furthermore, it took almost an hour for someone to contact the police.

Overcoming the bystander effect

Psychologists claim that merely being aware of the bystander effect is a massive first step toward overcoming it. When you become aware of how your human brain, conditioned by societal norms as well as millions of years worth of evolution, may be affecting your behaviour on an unconscious level; you give yourself a chance of stepping out of that haze and taking control of your actions.

Matt Langdon, who has worked with renowned psychological researcher Philip Zimbardo to help people develop heroic tendencies, explains that even one person acting in a crisis can make a big difference, as that then opens the gateway for others to overcome the bystander effect.

What if I’m the one who needs help?

In this case, a recommended tactic is to single out one person from the crowd and make eye contact with them. Kendra Cherry writes on “By personalizing and individualizing your request, it becomes much harder for people to turn you down.”
