Fear of missing out, widely known as FOMO, is a pervasive sense of anxiety that other people are having experiences you are not part of, coupled with a compulsive desire to stay connected so you do not fall behind. While the term gained mainstream traction alongside the rise of social media in the early 2010s, the underlying psychology is rooted in something much older: the human need to belong. Research over the past decade has linked FOMO to disrupted sleep, increased anxiety, impulsive financial decisions, and strained relationships, but the picture is more layered than a simple “social media is bad” narrative.
Why Humans Are Wired for It
FOMO is not a product of the smartphone era. It latches onto a drive that psychologists have studied for decades: the need to belong. Foundational work by Roy Baumeister and Mark Leary in the mid-1990s established that the desire for interpersonal attachment is a fundamental human motivation, one that shapes behavior across nearly every domain of life, from academic performance to emotional well-being.1PubMed Central. The Need to Belong: a Deep Dive into the Origins, Implications, and Future of a Foundational Construct When you feel excluded from a group experience, the discomfort you feel is not trivial or irrational. It is a signal from a social monitoring system that evolved when being cut off from the group could mean real danger.
What makes FOMO distinct from ordinary social disappointment is the role of perceived alternatives. You are not just sad you missed a party. You are scanning for evidence that right now, somewhere, life is happening without you, and you are anxious about what that gap means. Research grounded in self-determination theory has found that when people’s basic psychological needs for competence, autonomy, and relatedness are not met, they become more susceptible to FOMO. A key driver in that chain is relative deprivation: the feeling that others have more than you do, socially speaking.2PubMed. Basic psychological needs satisfaction and fear of missing out: Friend support moderated the mediating effect of individual relative deprivation That sense of falling behind socially amplifies the urge to check in constantly.
What Happens in the Brain
Neuroimaging research has started to map what FOMO looks like inside the skull, and the findings challenge a common assumption. You might expect FOMO to be mostly about the sting of exclusion, but brain-scan evidence suggests the opposite. In one study, people who scored high on FOMO showed increased activation in the right middle temporal gyrus specifically when they were being included in a social scenario, not when they were being left out.3Computers in Human Behavior. Fear of missing out (FOMO) is associated with activation of the right middle temporal gyrus during inclusion social cue That same brain response correlated with a stronger need for social approval. In other words, FOMO seems to reflect a heightened sensitivity to social rewards rather than a heightened pain response to rejection. People with high FOMO are not unusually hurt by exclusion; they are unusually drawn to inclusion.
This fits with broader research on how social media hooks users. Early engagement with platforms tends to be driven by positive reinforcement: the small dopamine-linked pleasure of a like, a comment, or seeing a friend’s post. Over time, as that positive reward loop starts to fade, people increasingly use platforms to avoid the negative feeling of being left out. The habit shifts from seeking pleasure to escaping discomfort.4PubMed Central. The Emotional Reinforcement Mechanism of and Phased Intervention Strategies for Social Media Addiction FOMO lives squarely at that transition point, fueling the kind of compulsive checking that keeps you scrolling long after the fun has drained away.
Who Feels It Most
Age is one of the strongest predictors. Research measuring FOMO and anxiety across age groups has found that FOMO peaks in participants under 18 and generally declines with age, with anxiety scores following a similar downward slope. The correlation between FOMO and anxiety in that research was substantial.5International Journal of Social Science Research and Review. The Psychology of Missing Out: Age-Wise Patterns of FOMO and Anxiety Younger users also tend to cluster on platforms built around real-time visual content like Instagram and Snapchat, which are especially effective at broadcasting what everyone else is doing right now. Older adults, by contrast, gravitate toward platforms like Facebook, where the social dynamics are somewhat less centered on immediacy.
Personality matters too. A meta-analysis looking at the Big Five personality traits found that neuroticism had the strongest positive link with FOMO, with a moderate correlation. That makes intuitive sense: people who are more emotionally reactive and prone to worry are also more likely to ruminate over what they might be missing. Extraversion showed a small but statistically significant positive association as well, while conscientiousness was slightly negatively correlated with FOMO.6Personality and Individual Differences. The relationship between Big Five personality traits and fear of missing out: A meta-analysis Agreeableness and openness showed no meaningful connection either way. One study of TikTok users specifically confirmed the extraversion link, finding that more extraverted users reported higher FOMO.7Clinical and Counselling Psychology Review. Personality Traits and Fear of Missing Out (FOMO) as Predictors of Self-Esteem in TikTok Users
The combination paints a clear picture. If you are young, emotionally reactive, sociable, and spend a lot of time on visually driven social platforms, FOMO has more surface area to grab onto. But age and personality are tendencies, not destiny. Plenty of older, laid-back people experience FOMO in specific contexts, from workplace Slack channels to group chats that move fast.
The Mental Health Toll
FOMO’s link to anxiety is one of the most replicated findings in this area of research. The cognitive side of FOMO manifests as repetitive checking: refreshing feeds, scanning notifications, monitoring group chats for activity. That vigilance feeds anticipatory anxiety, the nervous feeling that you are about to miss something important. Over time, this pattern is associated with the emergence of depressive symptoms in some people, and the combination of FOMO and interpersonal stress has been tied to insomnia and broader declines in mental health.8PubMed Central. Fear of missing out: A brief overview of origin, theoretical underpinnings and relationship with mental health
Sleep disruption deserves special attention because it creates a feedback loop. A study of medical students found a significant positive correlation between FOMO and poor sleep quality as measured by a standard clinical index, and anxiety was correlated with both.9PubMed Central. Fear of Missing Out Syndrome and its Impact on Sleep Quality in Medical Students: A Cross-sectional Study If FOMO keeps you checking your phone before bed, the resulting poor sleep makes you more anxious the next day, which in turn makes you more vulnerable to FOMO. Breaking that cycle often requires targeting the sleep end of the problem as much as the phone end.
FOMO has also been linked to a range of negative physical feelings. It is associated with emotional tension, reduced perceived life competency, and negative effects on physical well-being, though the evidence on bodily symptoms is less detailed than the mental health data.10PubMed Central. Fear of missing out: A brief overview of origin, theoretical underpinnings and relationship with mental health The physical side likely reflects the downstream effects of chronic low-grade stress rather than FOMO causing distinct somatic problems on its own.
How FOMO Shapes Behavior Beyond the Screen
The consequences of FOMO extend well past how often you check your phone. Research on young adults, including those with alcohol use disorder, found that FOMO is a positive predictor of health risk-taking.11PubMed Central. Exploring the role of fear of missing out in coping and risk-taking among alcohol use disorder and general young adult populations The mechanism is straightforward: if you are anxious about being left out, you are more likely to say yes to things you would otherwise pass on, whether that means drinking more than you intended, staying out when you should sleep, or joining an activity that feels risky because everyone else seems to be doing it.
FOMO also drives a less obvious behavior: digital hoarding. A study of Chinese young adults found that people who engage in upward social comparison on social media are more likely to compulsively save content they never actually read or revisit. FOMO mediated that relationship, acting as the link between seeing others’ curated lives and frantically bookmarking articles, screenshots, and posts “for later.” Interestingly, mindfulness weakened that chain at multiple points, reducing both the direct path to hoarding and the FOMO that fueled it.12PubMed Central.

FOMO and Your Wallet
The financial world has become one of FOMO’s most visible arenas. Research on stock market behavior indicates that FOMO amplifies emotional reactions to market trends, pushing investors toward irrational decisions that chase short-term gains at the expense of long-term stability. Social media and financial content platforms play a critical role in this dynamic, creating herd behavior that contributes to market volatility and speculative bubbles. The “meme stock” phenomenon, where retail investors piled into certain stocks largely because everyone else seemed to be, is a textbook example. Younger investors are especially susceptible, largely because they rely more heavily on social media for investment information and are more likely to focus on potential gains while overlooking risks.13ResearchGate. The Effects of FOMO on Investment Behavior in the Stock Market
This is not limited to stocks. The same dynamic shows up in cryptocurrency trading, real estate bidding wars, and even limited-edition consumer products. Any time a purchase is framed as scarce or time-limited, FOMO is the lever being pulled. Retailers have known this for decades with flash sales and “only 3 left” labels, but algorithmic feeds supercharge the effect by surrounding you with evidence that other people are already buying.
FOMO in Relationships
One of the more concrete ways FOMO erodes relationships is through phubbing: the habit of snubbing the person you are physically with in favor of your phone. Research on this found that FOMO acts as a mediator between certain personality patterns and phubbing behavior. People with higher emotional reactivity and a tendency to fuse their identity with others reported more FOMO, which in turn predicted more phone-snubbing during face-to-face interactions.14PubMed Central. Exploring the personality and relationship factors that mediate the connection between differentiation of self and phubbing The path from FOMO to phubbing was statistically significant, even though romantic relationship satisfaction and loneliness themselves did not directly predict phubbing in the same analysis.
The implication is worth sitting with. It is not that unhappy people phub their partners more. It is that people driven by FOMO phub their partners more regardless of how satisfied they report being in the relationship. Your partner’s phone-checking may have less to do with how they feel about you and more to do with an anxious pull toward whatever else might be happening online. That reframing can be useful for couples who fight about screen time, because it shifts the conversation from “you do not care about me” to “something is making you feel like you need to check.”
Cultural Variations
FOMO is not experienced identically around the world. A cross-cultural comparison between the United States and Italy found significant differences in how FOMO networks are structured, reflecting broader cultural patterns of individualism and collectivism. Italian participants placed more emphasis on shared social experiences, while American participants were more oriented toward comparative social evaluations.15Personality and Individual Differences. A cross-cultural examination of Fear of Missing Out and gender differences between the USA and Italy: Evidence from a network analysis In plainer terms, Italian FOMO tends to look like “I want to be part of what my group is doing,” while American FOMO tends to look like “Am I falling behind compared to what others are achieving?”
That distinction matters for understanding why the same social media post can trigger different reactions in different cultural contexts. A photo of friends at dinner might provoke warm longing in one cultural setting and competitive anxiety in another. It also suggests that interventions need to be culturally tuned. A strategy that works for someone whose FOMO is driven by social comparison may not help someone whose FOMO is driven by communal belonging needs.
FOMO at Work
The workplace has its own flavor of FOMO, distinct from the social media variety. Workplace FOMO, sometimes called wFoMO in the research literature, is the anxious feeling that important conversations, decisions, or opportunities are happening when you are not online or in the office. A study of employees found that workplace FOMO and the related pressure to respond immediately to work messages (known as workplace telepressure) were linked to greater use of work-related technology during leisure time. That after-hours connectivity in turn predicted worse psychological detachment from work and higher perceived stress.16PubMed Central. I Do Not Want to Miss a Thing! Consequences of Employees’ Workplace Fear of Missing Out for ICT Use, Well-Being, and Recovery Experiences
The always-on culture of Slack channels, Teams notifications, and email chains feeds this directly. If you have ever checked your work messages during dinner because you were worried about missing an important thread, that is workplace FOMO in action. The irony is that the resulting loss of recovery time during evenings and weekends likely makes you less effective during actual work hours, creating another self-defeating loop.
Can You Actually Reduce FOMO?
The evidence on interventions is still developing, but cognitive behavioral approaches show promise. One study tested a version of cognitive behavioral therapy on students and found a statistically significant reduction in FOMO scores, with the mean score dropping meaningfully from before to after the intervention. The effect size was very large.17International Journal of Islamic Educational Psychology. Efficacy of Islamic-Integrated Cognitive Behavioral Therapy for Reducing Fear of Missing Out (FOMO) in Madrasah Students This is a single study with a specific population, so it is too early to generalize broadly, but the core principles of CBT — identifying distorted thoughts, challenging catastrophic interpretations, and practicing behavioral alternatives — align well with what we know about FOMO’s cognitive patterns.
The digital hoarding study mentioned earlier found that mindfulness moderated the link between social comparison and both FOMO and hoarding behavior.18PubMed Central. Storing, Not Reading: Investigating the Link Between Upward Social Comparison via Social Media and Digital Hoarding Behavior in Chinese Youth Mindfulness is not a magic fix, but the finding is consistent with a broader pattern: practices that help you stay present and reduce automatic social comparison tend to weaken FOMO’s grip. The research on basic psychological needs also points toward a structural intervention. When people feel competent, autonomous, and connected in their offline lives, they are less vulnerable to the pull of checking whether they are missing something better.19PubMed. Basic psychological needs satisfaction and fear of missing out: Friend support moderated the mediating effect of individual relative deprivation
Practical steps tend to cluster around a few themes: scheduled breaks from notifications rather than willpower-based resistance, investing in face-to-face social time that satisfies belonging needs directly, and paying attention to which specific platforms or accounts reliably trigger the comparison spiral. The goal is not to eliminate the desire to stay connected, which is healthy and deeply human, but to keep it from running on autopilot.
JOMO and Its Limits
The concept of JOMO, or “joy of missing out,” has gained popularity as FOMO’s optimistic counterpart: the idea that you can find contentment in disconnecting and doing your own thing. It sounds appealing, but research suggests the picture is more complicated. A study examining JOMO found that it may be uncommon given the general human preference to connect with others. For some people, embracing JOMO was associated with positive self-perception, but for others, what looked like contentment with disconnection actually overlapped with social anxiety.20Telematics and Informatics Reports. JOMO: Joy of missing out and its association with social media use, self-perception, and mental health
That finding is a useful corrective. Telling someone who is struggling with FOMO to “just enjoy missing out” can be like telling someone with insomnia to “just relax.” For people who genuinely prefer solitude and have satisfying offline lives, stepping back from social media may feel freeing. For people whose withdrawal is driven by avoidance rather than genuine preference, JOMO branding can mask a problem rather than solve one. The distinction between choosing to disconnect and retreating because social engagement feels threatening is worth paying attention to, especially if you notice that your “JOMO” comes with relief rather than pleasure.
