• Definition: It's when people are less likely to help others in an emergency if other people are present.
• False Belief: We think we'd act differently, but research says otherwise.
• Anomaly: It contradicts the saying "there's safety in numbers."

• Diffusion of Responsibility: If others are around, we think someone else will help.
• Ambiguity: If we're not sure it's an emergency, we might not act.
• Group Inhibition: We follow the crowd. If no one acts, neither do we.
