I used to think Mensa was basically a secret lair for people who could solve Rubik's cubes behind their backs while reciting Pi to the thousandth digit. It isn't. Not even close. After spending my year in Mensa, I realized the reality is way weirder, occasionally more boring, and significantly more human than the "genius" tropes suggest.
People ask me all the time if it's worth the dues. They want to know if everyone there talks like a walking encyclopedia or if it’s just a glorified board game club. Honestly? It's both. And neither.
Joining requires scoring in the upper 2% of the general population on an approved intelligence test. That’s it. There’s no character reference. No background check on your common sense. You just need the score.
The Reality of the Mensa Entrance Exam
Taking the test is nerve-wracking. You’re in a room—usually a library basement or a rented community center—with a proctor who takes the timing very seriously. I remember the silence. It was heavy. You’re flipping through matrices and pattern recognition puzzles, feeling your brain sweat.
When that letter arrives in the mail, there’s a genuine rush. You’ve been validated. But then the questions start hitting you. What now? Do I get a cape? Does my boss have to listen to me more?
Spoilers: No.
What Actually Happens at the Meetings
Most of my year in Mensa was spent in "SIGs" or Special Interest Groups. This is the heart of the organization. Because the only thing members have in common is a high IQ, their interests are all over the place.
I walked into my first local gathering expecting high-level physics debates. Instead, I found a group of people intensely arguing about the best way to sourdough bread. It was passionate. It was granular. It was, frankly, a bit much.

- The Social Dynamic: It’s a mix of socially awkward academics, eccentric hobbyists, and surprisingly "normal" professionals who just like puzzles.
- The Vibe: Imagine a college lounge where nobody is worried about being "too much."
- The Conversations: They jump. Quickly. You go from discussing the nuances of 18th-century maritime law to the ethics of AI in about four minutes.
It’s refreshing to not have to "dim down" your vocabulary, but it can also be exhausting. Everyone wants to be the smartest person in the room, even if they won't admit it.
The Ego Trap and the Intellectual Isolation
Being told you're "statistically superior" in logic is a dangerous thing for the ego. During my year in Mensa, I saw people who used their membership as a shield. They’d struggle with basic social cues or job performance but fall back on, "Well, I’m in Mensa, so I must be right."
Intelligence is a tool, not a personality.
There’s a concept in psychology called the "Communication Gap." Some researchers suggest that when IQ scores differ by more than 30 points, effective communication becomes significantly harder. For many members, Mensa is the first place they feel they aren't speaking a second language.
That’s the value. It’s not about feeling better than others; it’s about finding people who process information at your specific frequency.
The Annual Gathering: A High-Speed Brain Dump
If local meetings are a slow burn, the Annual Gathering (AG) is a forest fire. Thousands of Mensans descend on a hotel for a few days of 24-hour programming.
There are speakers on everything from lock-picking to astrophysics. There’s a hospitality suite that never closes, filled with snacks and board games. You see people wearing shirts that say "I’m here because you broke something" and others in full suits.

It is a concentrated dose of "intense." I met a guy who had three PhDs and spent four hours explaining why he preferred 1990s Japanese RPGs over modern ones. He was brilliant. He was also completely unable to figure out how to work the hotel's coffee machine.
That’s the Mensa experience in a nutshell. High processing power, occasionally low RAM for everyday life.
Is the Membership Worth the Cost?
Annual dues are around $79 in the US. For that, you get the magazine (the Mensa Bulletin), access to the SIGs, and the right to put a sticker on your car that you probably shouldn't use if you want to be liked by your neighbors.
If you’re looking for a professional networking powerhouse like a top-tier MBA alumni group, you’ll be disappointed. Mensa is social. It’s about community.
I found that the most valuable part of my year in Mensa was the realization that "genius" doesn't solve your problems. It doesn't make you happier. It just gives you a more complex way to analyze why you're unhappy.
Breaking the Myths
- We aren't all rich. I met plenty of members living on modest pensions or working entry-level jobs because they lacked the "hustle" or social navigation skills to climb corporate ladders.
- We aren't all "smart." Being good at logic puzzles doesn't mean you have emotional intelligence or financial literacy. I’ve seen Mensans fall for obvious scams.
- It’s not a cult. You can leave whenever you want. Nobody follows you.
The organization is currently facing the same challenges as any legacy hobbyist group: an aging demographic and the struggle to stay relevant in an era where "communities" are built for free on Discord or Reddit.

The best part of Mensa is the permission people give themselves to be obsessed with a niche topic. You don't need a high IQ score to spend a weekend learning about urban planning or linguistics. Just do it.
Focus on "Intellectual Humility."
The most impressive people I met in Mensa were the ones who were quick to say "I don't know." The ones who led with their membership usually had the least to offer in actual conversation.
Vary your social circles.
Spending a year with people who think exactly like you is a trap. It creates an echo chamber of logic. Make sure you're also hanging out with people who prioritize empathy, physical skill, or artistic intuition.
Test yourself for the right reasons.
Take the Mensa practice test online if you're curious. But do it for the data point, not for the identity.
Intelligence is just one metric of a human being. After 12 months, I realized I’d rather be around someone kind and "average" than someone brilliant and insufferable.
My year in Mensa taught me that being smart is just a starting line. What you do after the whistle blows is what actually matters.
How to Move Forward
- Audit your curiosity: Write down three things you've always wanted to learn but felt were "too hard." Spend 20 minutes today on Wikipedia or YouTube looking at the foundational concepts.
- Practice "Steel-manning": When you disagree with someone, try to build the strongest possible version of their argument. It’s a classic Mensan mental exercise that builds better logic and better relationships.
- Look for local "Think-Tanks": You don't need to be in the 98th percentile to join a local philosophy club or a high-level strategy board game group. These offer 90% of the social benefits of Mensa without the gatekeeping.
