FOMO, or “Fear of Missing Out,” refers to the apprehension or anxiety that individuals experience when they believe they might be missing out on rewarding experiences or opportunities that others are enjoying. This feeling often arises from seeing others’ social media posts, hearing about events, or perceiving that others are having more fulfilling or exciting experiences. FOMO can drive people to participate in activities or events not necessarily out of genuine interest, but rather to avoid the feeling of exclusion or regret.
