FOMO, or “fear of missing out,” is a pervasive anxiety that other people are having rewarding experiences without you. It shows up as a nagging feeling that you should be somewhere else, doing something else, or that you’re falling behind socially. The term was coined in 2004 by Patrick McGinnis in a humor column for the Harvard Business School student newspaper, but the feeling it describes is far older. What’s changed is how powerfully social media amplifies it.
Why FOMO Happens
FOMO isn’t just about wanting to go to a party. It’s rooted in three basic psychological needs: feeling connected to others, feeling competent, and feeling in control of your own choices. When any of these needs go unmet, FOMO intensifies. Someone who feels socially disconnected, for instance, develops a stronger desire to belong, which feeds directly into the worry that they’re being left out. When those three needs are reasonably satisfied, FOMO drops.
Social comparison is the engine that keeps it running. You’re not measuring your life against some abstract standard. You’re measuring it against the curated highlight reels of people you know. That comparison creates a sense of relative deprivation, the feeling that others have more or better experiences than you do, even when your own life is objectively fine.
How Social Media Fuels It
Social media didn’t invent FOMO, but it gave it a delivery system. Several specific platform features make the feeling worse. Disappearing content, like stories that vanish after 24 hours, creates urgency. You feel pressure to check in before the moment passes. Notifications pull you back constantly. Feeds that refresh endlessly give you an inexhaustible supply of other people’s experiences to compare against your own.
The result is a cycle: FOMO motivates you to check your accounts to stay connected and avoid feeling left out, which exposes you to more content that triggers FOMO, which makes you check again. Research describes this as a preoccupation with what’s happening online and how others are reacting, either positively or negatively, to your presence there. The worry isn’t just “I’m missing a fun event.” It extends to missing conversations, news, inside jokes, or opportunities that feel time-sensitive.
What It Does to Your Health
FOMO correlates with several measurable health problems. In a study of medical students, higher FOMO scores were linked to poorer sleep quality, higher anxiety levels, and greater symptoms of depression. The connections weren’t subtle. Anxiety showed a particularly strong association with FOMO, and both of those were tied to excessive smartphone use. Smartphone dependence, in turn, correlated with worse sleep, more anxiety, and more depressive symptoms, creating a web of overlapping effects.
There’s also a brain structure component. People with higher FOMO levels tend to have thinner cortex in a region called the precuneus, a hub involved in thinking about yourself and processing social information. This area is part of a larger brain network that activates during self-reflection and social cognition. Whether FOMO causes these structural differences or people with thinner cortex in this region are simply more prone to FOMO isn’t yet clear, but the association is consistent.
FOMO and Spending
The fear of missing out doesn’t stay in your head. It reaches your wallet. People prone to FOMO feel a strong urge to imitate what their peers are doing, which makes them more susceptible to purchasing triggers. Limited-time offers, “selling fast” labels, and countdown timers all exploit this tendency. While these triggers can prompt immediate purchases, research involving 57 FOMO-prone consumers found that the purchases frequently generated negative emotional and cognitive effects afterward. People bought things, then felt regret, frustration, or dissatisfaction. The initial rush of not missing out gave way to the realization that the purchase wasn’t something they actually wanted.
How It’s Measured
Psychologists use a standardized tool called the Fear of Missing Out Scale, a 10-item questionnaire developed by Andrew Przybylski. Each item is a statement like “I get anxious when I don’t know what my friends are up to,” and you rate how true it feels on a scale from 1 (not at all true) to 5 (absolutely true). Scores range from 10 to 50, with higher scores indicating stronger FOMO. It’s a self-report measure, meaning there’s no clinical cutoff that qualifies as a diagnosis. FOMO isn’t a mental health disorder. It’s a psychological pattern that, at high levels, can worsen existing conditions like anxiety and depression.
FOMO’s Newer Cousins
FOMO has spawned a family of related acronyms. FOBO, or “fear of better options,” describes the paralysis of refusing to commit to a choice because something better might come along. FOPO, “fear of other people’s opinions,” captures the anxiety of being judged for your decisions. These aren’t clinically defined conditions either, but they name specific flavors of the same underlying insecurity: the worry that you’re doing life wrong compared to everyone else.
Shifting Toward JOMO
The counterweight to FOMO has its own acronym: JOMO, the joy of missing out. Cleveland Clinic describes it as being selective with what you do without worrying about what others are doing. It doesn’t mean becoming a hermit. It means consciously choosing what you participate in based on what you actually value, not what you feel pressured to attend.
A few practical strategies help make that shift. Limiting social media, even temporarily, reduces the constant comparison that feeds FOMO. When you take a break, the urgency fades and you have more mental space for your own goals and interests. Setting boundaries with your time matters too. Before saying yes to something, it helps to ask a simple question: am I doing this because I’m afraid of missing out, or because I genuinely want to?
Saying no without apologizing is another skill worth building. You don’t owe anyone an explanation for skipping an event. And sometimes, pausing before you react to a trigger, whether it’s a group chat, an Instagram story, or a flash sale, is enough to break the cycle. That pause lets you evaluate whether the thing pulling at your attention actually aligns with what brings you satisfaction, or whether it’s just FOMO doing what FOMO does.
