What is the 'bystander effect' in Social psychology?

The 'bystander effect' refers to the phenomenon where individuals are less likely to offer help to a victim when other people are present. This effect occurs because the presence of others can create a diffusion of responsibility, where individuals feel less compelled to take action, believing that someone else will intervene. Factors such as social influence and audience inhibition also play a role, as people may hesitate to act due to a fear of embarrassment or a desire to conform to what they perceive as the group’s behavior.

This concept is pivotal in understanding human behavior in social situations, particularly in emergencies. It highlights how the behavior of others can influence an individual's decision to help or not, emphasizing the importance of context in social dynamics. The phenomenon contrasts sharply with situations where individuals are alone, often resulting in a greater likelihood of intervention.
