What is groupthink? It’s when a single opinion is expressed, and the group rallies behind it without developing opinions of their own, meaning they don’t express those opinions. Sometimes groupthink is a result of the loudest or most persuasive person making others feel like their own opinion isn’t worth sharing. When a person feels like they might be the only person in a crowd who has their particular thought, they aren’t likely to share it. In fact, they’ll change the opinion they express to conform to the group’s. Individuality disappears, and with it the valuable insights of the individual.
