1. The birth of FOMO
Patrick McGinnis (Harvard MBA) first used "FOMO" in a 2004 "The Harbus" magazine column, describing MBA students' pressure to attend every party / seminar / alumni event. The term went mainstream in the 2010s with SNS.
2. 3 dimensions of FOMO
- Social FOMO: friends having more fun in gatherings / trips / relationships
- Experiential FOMO: missing trends / restaurants / travel spots / concerts
- Informational FOMO: missing news / stocks / crypto / trend information
3. Clinical impact
Przybylski et al. (2013) Computers in Human Behavior:
| Metric | High-FOMO group | Low-FOMO group |
|---|---|---|
| Depression (BDI) | ×1.8 | baseline |
| SNS use time | 6+ h/day | 1–2 h/day |
| Sleep quality (PSQI) | Poor | Good |
| Self-esteem | Low | High |
| Attention / concentration | Low | High |
| Phone use while driving | High (accident risk) | Low |
4. The rise of JOMO
Anil Dash (blogger) coined "JOMO" in 2012. Core: the mental freedom of "intentional missing". Mainstreamed in the 2020s along with the "slow life" and "minimalism" trends after the pandemic. Key differences:
| Axis | FOMO | JOMO |
|---|---|---|
| Agency | External (others decide) | Your own decision |
| Emotion | Anxiety / deprivation | Peace / satisfaction |
| Comparison | Upward contrast (#260) | No comparison |
| SNS | Compulsive checking | Conscious use or rest |
| Commitments | "YES" to all | Selective "NO" |
5. Korean youth's FOMO environment
- Active university / workplace group chats
- Instagram / X 24-hour friend "highlights"
- Storm of drinking parties, alumni reunions, weddings
- Weekend "what did you do?" pressure
- Trends (restaurants / travel / dramas) rotate weekly
- Bombardment of stock / crypto "profit boasting"
- Korean 20s average SNS 7 h/day (KCC)
6. FOMO self-test (Przybylski 10-item short form)
- I get anxious when friends seem to be having more fun
- I worry about missing out when friends are gathering
- I need to always know what friends are doing
- I check what others are doing even on vacation / trips
- I worry if I can't spend good times with friends
- I'm bothered when I miss friends' "inside jokes"
- I'm uncomfortable when friends don't ask about my plans
- I'm uncomfortable when I'm late on new trends
- I focus on friends' affairs more than my own
- I waste time checking friends' schedules on SNS
Each 1–5 points. 35+ = high FOMO, 25–35 = medium, under 25 = low.
7. 4-week JOMO conversion protocol
Week 1: FOMO awareness
- Journal daily FOMO moments (time, trigger, emotion)
- Identify the top 5 trigger SNS / apps / chat rooms
- Measure FOMO score
Week 2: SNS environment adjustment
- Turn off Instagram / X / TikTok "story" / "feed" notifications
- SNS 30 min/day only (app timer)
- Mute group chats (except family)
- No phone in bed / at meals
Week 3: conscious "NO"
Week 4: build JOMO zones
- Weekly "digital sabbath" (Sat or Sun afternoon)
- One deep 1:1 meeting (no groups)
- 90 minutes of nature / walking / reading
- Develop a hobby and finish one piece
- Ritualize "phoneless meals" with family
8. Average results after 4 weeks
Hunt et al. (2018) Penn State and other studies combined:
- FOMO score -30 to -50%
- Depression (PHQ-9) -20%
- Sleep +45 min/day
- Self-esteem +20%
- "What was missed" was reported as almost nothing
9. Korea-specific application
Drinking parties / alumni reunions
Attend about once a month; the rest is "personal commitment". After a year, friendship loss is near zero — only the core friends remain.
Family / holidays
See #234 holiday family conflict. Short visits, prioritize 1:1 time.
Stock / crypto FOMO
See #237 financial stress. 90% of "get-rich-quick" trends result in losses. Check once a day; auto-invest a diversified portfolio.
10. Crisis signs
- Depression / anxiety explosion without SNS (lasting 1+ weeks)
- Important relationships crumble while only SNS activity continues
- Debt / overspending because of FOMO
- Persistent sleep under 5 hours
Then: psychiatric evaluation — digital addiction / depression / anxiety can coexist. 1577-0199.
