Why Crowds Make Us Callous

How we become different people in the presence of others.

Posted Oct 19, 2011

As often happens in cases like these (whether the 1964 murder of Kitty Genovese in Queens, NY or the 1993 abduction and torture of young James Bulger outside Liverpool, England) the accusations and recriminations quickly started to fly. What's the matter with Chinese society?, asked one line of questioning. Others pointed a finger more broadly, suggesting that this is yet another example of the continued deterioration of common decency and humanity in the modern age.


But the infamous Genovese case was 50 years ago. And I can cite you examples of similar instances of bystander apathy across time period and continent. There must be more to these stories than a sudden, recent shift in common decency. And there's certainly a lot more to them than the personality-based conclusions we usually jump to.

For most of us who read about the tragic case in China, our reaction will be to indict these marketgoers as particularly indifferent, apathetic, and callous human beings. What's wrong with these people?, we'll ask, confident that we would have acted differently.

Again, maybe.

But it's also the case that there are specific situations that render all of us–yes, you and me included–less likely to take action and inject ourselves into the affairs of others. And one of the most noteworthy of these situations is being in a crowd. As a generalized rule, we're less likely to help when we're surrounded by others.

There are a variety of explanations for this tendency towards apathy in crowds:

• When in densely populated areas, we're simply less likely to notice someone in need. In busy areas, there's so much going on that any one event becomes less likely to draw our divided attention.

• We're less likely to interpret events as emergencies when in the company of others. Sure, a child hit by a truck is an unambiguous crisis. But other emergencies are less clear-cut: Are the 3:00 am screams outside someone in need of help or a loudmouth who had too much to drink? Is the animated argument in the parking lot a harmless domestic squabble or an altercation in need of intervention? When we're unsure about events, we look to those around us to gauge their reactions. When no one else seems alarmed, we're more likely to keep to ourselves as well.

• And, simply, having other people around lets us rest on the assumption that someone else will take care of it. Whether it's the out-of-focus projector at the movie theater or the accident that merits a 911 call, when we're with others, we experience diffusion of responsibility.

Just how strong is our tendency for non-intervention in crowds? Well, simply imagining being surrounded by people is enough to make us less helpful. In one creative set of studies, researchers at Princeton instructed participants to visualize themselves in a crowded movie theater. Or out to dinner with 30 friends. After answering unimportant questions–like, what room temperature would they prefer in the theater–participants moved on to an ostensibly unrelated charity survey.

So does this power of context to influence our helping tendencies excuse passersby who fail to assist during an emergency? Not at all. But it does help us understand a bit better how these incidents occur. It prevents us from getting too overconfident in "bad apple" explanations or the conclusion that this would never happen in my neighborhood. And, perhaps most importantly, learning how the presence of others promotes apathy is often enough to prevent us from falling victim to this tendency in the future. When we understand how crowds can make us callous, we know too much to rest comfortably in our own inaction.
