What is FOMO? The fear of missing out, explained

FOMO is not vanity or weakness. It is an old social instinct, the need to belong, plugged into a feed engineered to show you everything you are not part of.

FOMO is one of those acronyms that spread because it named something everyone already felt. So, plainly: what is FOMO. It stands for the fear of missing out, and it describes the anxious sense that others are enjoying experiences without you, paired with a compulsion to stay constantly connected so you never miss anything. It feels modern, but it runs on a very old instinct.

The definition, and the research

The fear of missing out was given a careful definition in a 2013 study by Andrew Przybylski and colleagues, who described it as a pervasive apprehension that others might be having rewarding experiences from which one is absent.[1] Their work did two useful things. It produced a validated scale to measure FOMO, and it traced where it comes from.

The root, they found, is not shallowness. It is unmet psychological needs. People who felt less connected to others, and less in control of their own lives, reported more FOMO. In other words, the feeling is an expression of a basic human drive to belong. When that drive is undernourished, the antenna for what you might be missing turns up.

Why the feed makes it worse

Here is where an old instinct meets new technology. A social feed is, structurally, a continuous stream of other people’s highlights: the parties, the holidays, the wins, all curated and posted at their best. That is close to the perfect stimulus for FOMO. You are comparing your ordinary inside view of your own life with everyone else’s edited outside view of theirs.

And the comparison appears to have a cost. In a well-known study, Ethan Kross and colleagues tracked young adults’ Facebook use and found that the more they used it, the more their moment-to-moment mood and overall life satisfaction declined over time.[2] The feed promises connection and often delivers comparison.

How to feel it less

You cannot delete an instinct, but you can stop feeding it so heavily.

  • Reduce the input. Less feed, less fuel. In a controlled study, people who limited social media to about 30 minutes a day for three weeks reported meaningful drops in loneliness and depression compared with a control group.[3] You do not have to quit, only to bound it.
  • Curate ruthlessly. Mute or unfollow the accounts that reliably leave you feeling behind. You are allowed to choose what your attention is exposed to.
  • Reconnect for real. Because FOMO grows from unmet belonging, the strongest antidote is actual connection: time with people, in person, off the feed.
  • Practise enough. The opposite of missing out is not doing everything. It is being genuinely present where you are, which is a skill worth building.

That last point is the heart of it. The fear of missing out keeps you looking at the screen for the life happening elsewhere, and away from the life happening here. Learning to be content in your own unremarkable, unposted moment is the quiet skill underneath all of this, and it is what How to Be Bored Again is about.

Questions

What does FOMO mean?+
FOMO stands for the fear of missing out: the uneasy feeling that other people are having rewarding experiences you are absent from, along with a strong urge to stay continually connected so you do not miss anything. Researchers define it as that pervasive apprehension, and it is closely tied to how often and compulsively people check social media.
What causes FOMO?+
Underneath it is a normal human need to belong and to feel connected. Research links FOMO to unmet psychological needs: people who feel less connected or less in control of their lives tend to feel it more. Social media then amplifies it, because feeds show a constant, curated highlight reel of everyone else's best moments, which is precisely the input designed to trigger the feeling.
Is FOMO bad for you?+
Higher FOMO is associated with more compulsive social media use and lower mood and life satisfaction, and some studies link heavy social media use itself to declines in well-being. It is a normal feeling, not a disorder, and this is not medical advice. But if checking is constant and leaves you feeling worse, it is worth addressing the habit.
How do I stop FOMO?+
Reduce the input that feeds it and reconnect in real life. Limiting social media helps: in one study, capping use at about 30 minutes a day for three weeks reduced loneliness and depression. Beyond that, curating or muting accounts that trigger comparison, scheduling real time with people, and practising being content with where you are all lower the background hum of missing out.
