Pretending to have knowledge about something, they know nothing about. The next time you sit down to have a conversation with someone, note your behavior. Have you ever accidentally lied when someone asks you if you know about a given situation whether it’s a breaking news story, the latest celebrity gossip, or something that happened to a mutual friend? Many people simply respond in the affirmative, even if they know nothing about the situation. Scientists say that because our brains have a desire to move the conversation along, and because we prize knowledge so highly, we often fake knowledge about topics that we haven’t a clue about.
