The Sidewalk Incident
Chloe was walking back from her evening class when she saw a man stumble and collapse on the sidewalk. He didn't move. Passing cars slowed down, and several pedestrians glanced over, but no one approached him.
"I thought someone else would help," Chloe said to her friends later. "There were so many people around."
She hesitated, unsure if the man was in real danger. A few others looked concerned but kept walking. Chloe felt a growing discomfort. "I didn't want to overreact," she explained. "What if he was just resting?"
Eventually, a cyclist stopped and called for help. Paramedics arrived and confirmed the man had suffered a mild stroke. Chloe was shaken. "I could've done something," she said. "But I froze."
Chloe's experience reflects the bystander effect, a phenomenon where individuals are less likely to help in emergencies when others are present. This is often driven by diffusion of responsibility: the assumption that someone else will intervene.
In Chloe's case, pluralistic ignorance also played a role. Because no one else was acting, she assumed the situation wasn't serious. But everyone else was likely thinking the same thing.
