G - Group Identity
When 'I' slowly changes into 'we'.
Why? Because it is not just about Jehovah's Getuigen. It is about: football stadiums; festivals; concerts; political meetings; demonstrations; churches; mosques; businesses; military units; student associations. Everywhere people come together. Imagine... You are watching a World Cup final at home, all by yourself. You are excited. Now suddenly you are sitting among 60,000 supporters. Everyone stands up. Everyone sings. Everyone jumps. Everyone cheers. Within minutes, you feel much more emotion too. Have you suddenly become a different person? No. Your brain is doing what human brains have been doing for hundreds of thousands of years: tuning you in to the group. At a convention. Everyone neatly dressed. Everyone greeting each other. Everyone smiling. Everyone applauding. Everyone nodding. Everyone saying: "What a wonderful talk." That does not mean people are lying. They may genuinely have found it beautiful. But... The group atmosphere often intensifies the emotional experience. Psychologists call this, among other things: emotional contagion; social reinforcement; social identity. Not: Was it fake? But: Would you have felt exactly the same if you had listened to that same talk completely alone at home? That is a wonderful psychological question. Another nice example. Why do people sing in a stadium? Because everyone is singing. Why do people applaud? Because everyone is applauding. Why do people laugh louder in a theater? Because everyone is laughing. Why do people sometimes cry at the same time? Because emotions are contagious. All of that has been scientifically studied. There is even the term: Emotional Contagion Emotions literally spread through groups. Not because people are weak. But because our brain is constantly reading the emotions of others. Solomon Asch. He showed that people even came to judge simple lines incorrectly when almost the entire group deliberately gave a wrong answer. Not because people are stupid. But because group pressure is extremely powerful. And Henri Tajfel. He discovered that people already feel connected to a group... ...even when that group is completely randomly assembled. So imagine. You get a blue card. I get a red card. Within minutes, people already seem to think more positively about their own color. That is incredible. Because group identity explains why people can feel: "These are my people." "I belong here." "We understand each other." That feeling is often sincere. And that is why leaving is so incredibly difficult. Not only because you are leaving a belief. But because you are literally leaving your tribe . Closing Imagine... You hear the same talk. The same words. The same speaker. Once all by yourself at home. And once in a hall with eight thousand enthusiastic people applauding afterward. Would you experience exactly the same thing? Or would the atmosphere add something to your experience? There is no right or wrong answer to that. But even asking that question can help someone realize that our emotions do not come only from within, but are also influenced by the people around us . Scientific basis Henri Tajfel – Social Identity Theory : how people derive part of their identity from the groups they belong to. Elaine Hatfield, John Cacioppo & Richard Rapson – research on Emotional Contagion : how emotions can spread within groups. Solomon Asch – conformity experiments: how the presence of a group can influence our judgment, even in simple tasks. Muzafer Sherif – Robbers Cave Experiment : how group formation, loyalty and cooperation arise.
