What does the term "bystander apathy" refer to?

Bystander apathy refers to the phenomenon where individuals are less likely to offer help to a victim when other people are present. This is often due to a diffusion of responsibility, where individuals feel less compelled to act because they assume someone else will intervene. In group situations, people may look to one another to assess whether action is necessary, which can lead to inaction if no one steps forward. This psychological dynamic highlights how the presence of others can diminish the likelihood of aid being provided in emergencies, making it distinct from scenarios where individuals feel more personal responsibility, such as when alone.
