Most of us have experienced it. Someone harasses a stranger on the train but fellow commuters don't intervene. Or a person collapses in a busy city center, but no one rushes to their rescue. Psychologists call this phenomenon the "bystander effect." And it doesn't just happen in public, but frequently in the workplace.

In this article, we explore what the bystander effect is, and how to overcome it.

What is the Bystander Effect?

Social psychologists coined the term in the 1960s. In their research, they noticed people are less likely to help someone in need with onlookers present. They discovered that being in a group increases certain beliefs:

  • diffusion of responsibility – the belief that someone else will act (and they won't be singled out to blame for inaction).
  • assumptions – other people (such as doctors or the police) are more qualified to act.
  • ambiguity – "Does the person really need my help?"
  • social influence – focusing on how others behave rather than the situation. If people don't act, we conform and do nothing. [1]

Criticisms of the Bystander Effect

More recent research has suggested that the bystander effect isn't as common as once thought. A meta-analysis from 2011 found that bystanders are more likely to react to emergencies than non-emergency situations. And, if one person is seen helping someone, other bystanders are more likely to offer their help. [2]
