Mass Hysteria: How Collective Fear Shapes Human Behavior
Mass hysteria, also called collective hysteria or mass psychogenic illness, is a phenomenon in which groups of people share the same false beliefs, emotions, or physical symptoms without a clear physical cause. It is not a relic of the distant past. It is a recurring feature of human behavior, shaped by fear, uncertainty, social pressure, and the powerful need for belonging. Understanding mass hysteria offers a deeper view of how individuals think and act when they are swept into the emotional current of a group.
