Fear of Missing Out (FOMO) is a widespread form of anxiety characterized by an individual's concern about missing out on rewarding experiences or valuable information that others are having. This fear drives people to constantly monitor social media, news, or other information sources to ensure they are not falling behind or being excluded. At its core, FOMO is motivated more by the avoidance of potential loss than by the desire to gain new experiences, and it may lead to excessive information consumption, decision fatigue, and psychological stress.
