What does the term "bystander effect" refer to?

The term "bystander effect" refers specifically to the phenomenon where individuals are less likely to offer help to a victim when other people are present. This occurs because individuals may assume that someone else will take action, leading to a diffusion of responsibility. Each bystander may think that someone else will step in, which often results in inaction from all present. This psychological tendency demonstrates the importance of taking initiative in emergency situations, as the presence of multiple observers can paradoxically diminish the likelihood of any single person taking action to assist someone in need. Understanding the bystander effect is crucial for training individuals in first aid and emergency response, as it emphasizes the importance of being proactive and not relying on others to help in critical situations.
