Most people think of IQ like a leaderboard in a video game. If you aren't at the top, you're losing. We’ve been conditioned by movies and pop culture to believe that unless you’re solving complex equations on a window pane or joining high-IQ societies, your brain is somehow "basic." But here’s the reality: having an score that is nowhere near Mensa isn’t a failure of potential. It’s actually the mathematical reality for about 98% of the human population.
Intelligence is messy. It’s not a single fuel tank in your head that’s either full or empty.
The obsession with the "Genius" bracket—that elusive top 2%—has created a weird kind of "IQ anxiety." People take a free online test, see a 105 or a 112, and feel a sting of disappointment. Why? Because we’ve turned a statistical tool into a status symbol. Mensa requires a score at or above the 98th percentile on an approved, supervised intelligence test. For the Wechsler Adult Intelligence Scale (WAIS), that’s usually a 132. For the Stanford-Binet, it’s 132.
If you’re sitting at 100, you are exactly where the test designed you to be. You’re at the peak of the bell curve. You’re normal. And in the world of cognitive science, "normal" is actually incredibly capable.
The Bell Curve doesn't care about your feelings
Let's look at the math. The average IQ score is set at 100. The standard deviation is usually 15 points. This means that about 68% of people fall between 85 and 115. This is the "average" range. It’s where most doctors, lawyers, teachers, and engineers live.
When you have a score that is nowhere near Mensa, say a 105, you have the cognitive resources to do almost anything. You can learn a second language. You can master a trade. You can run a company. The gap between a 110 and a 135 isn't as wide as the numbers make it feel in daily life.
Dr. Richard Haier, a leading researcher in the neuroscience of intelligence and author of The Neuroscience of Intelligence, has spent decades looking at PET scans and MRIs. What he found is fascinating. Brain efficiency matters more than just "raw power." Someone with a lower score might actually have a more efficient neural pathway for a specific task than someone with a "genius" score who has to recruit more brain areas to solve the same problem.
High IQ is just a measure of "g"—general intelligence. It measures how fast you process logic, spatial patterns, and verbal analogies. It doesn't measure your "grit," your "creativity," or your "social intelligence."

Why "Average" is actually a superpower
There is a concept in psychology called the "Threshold Hypothesis." It suggests that after a certain point—usually around an IQ of 120—more intelligence doesn't necessarily lead to more success or creativity.
Think about it.
If you have a score that is nowhere near Mensa, you might actually be better at communicating with the general public. There is such a thing as a "Communication Gap." Research suggests that for effective leadership and communication, a gap of more than 30 IQ points between the leader and the led can cause a breakdown in understanding. If you are "too smart," you might struggle to simplify concepts or relate to the common struggles of your team.
Being in the middle of the curve means you speak the language of the majority.
Real talk about what Mensa actually is
Mensa is a social club. That’s it. It’s a place for people who score high on specific types of puzzles to meet up and hang out. It isn't a government body. It doesn't confer a degree.
I’ve known people in Mensa who couldn't figure out how to change a tire or manage a bank account. Conversely, some of the most successful entrepreneurs I know have an score that is nowhere near Mensa. They succeeded because they had high "Conscientiousness"—one of the "Big Five" personality traits that is actually a better predictor of job performance than IQ.
- IQ predicts how fast you learn.
- Conscientiousness predicts if you’ll actually show up and do the work.
- Emotional Intelligence (EQ) predicts if people will want to work with you.
If you have a 100 IQ and a 140-level work ethic, you will run circles around a 140 IQ person with a 100-level work ethic every single day of the week. Honestly.

The danger of the "Genius" label
Labeling kids as "gifted" can sometimes backfire. It’s called the "Fixed Mindset." If you think you're a genius because of a score, you might stop trying. You become afraid of failure because failure would mean you aren't a genius anymore.
People with a score that is nowhere near Mensa often develop better coping mechanisms. They know they have to study. They know they have to practice. This builds resilience.
Let’s look at the famous "Terman Study of the Gifted." Lewis Terman tracked a group of high-IQ kids (the "Termites") for decades. He expected them to become the world’s great leaders and Nobel Prize winners. Some did well. But many ended up in very ordinary jobs. Interestingly, Terman rejected two boys from his study because their IQs weren't high enough: William Shockley and Luis Alvarez.
Both of those "rejects" went on to win the Nobel Prize in Physics.
The kids with the score that is nowhere near Mensa (by Terman’s standards) outshone the "geniuses."
Testing is limited and biased
We have to acknowledge that IQ tests aren't perfect. They are a snapshot in time. If you’re tired, stressed, or didn't eat breakfast, your score can drop 10 points.
Moreover, standard tests like the Raven’s Progressive Matrices or the WAIS-IV focus heavily on Western-centric logic and educational norms. They don't measure "Practical Intelligence"—the "street smarts" that psychologist Robert Sternberg argues are just as vital for navigating the real world.

If you're worried about having a score that is nowhere near Mensa, remember that you’re being measured by a very narrow ruler. It’s like judging a whole library by the color of the book covers. It tells you something, but it doesn't tell you the story.
How to actually boost your cognitive "Output"
So you aren't a member of the high-IQ elite. Who cares? You can still optimize what you have. Cognitive plasticity is real. While you might not be able to fundamentally shift your base "g" by 40 points, you can absolutely improve your "Crystallized Intelligence"—the stuff you actually know and can do.
- Stop checking the number. IQ tests are fun puzzles, but they aren't a life sentence. If you took one and didn't like the result, put it away. It’s a data point, not a destiny.
- Focus on Meta-cognition. This is "thinking about thinking." Learn how you learn best. Do you need visuals? Do you need to teach it to someone else to understand it? This is a "power up" for any IQ level.
- Build your "Second Brain." Use tools. Notes apps, calendars, and AI assistants act as external cognitive loads. A person with an average IQ using a great organizational system will outperform a genius who relies on memory alone.
- Prioritize Sleep and Health. This sounds cliché, but chronic sleep deprivation can temporarily drop your functional IQ by a full standard deviation. You're basically making yourself "less smart" by staying up late scrolling.
- Diversify your skills. Being "smart" in one area (like logic) is great, but being "competent" in five areas (logic, social skills, finance, health, and a trade) makes you a powerhouse.
Moving forward without the Mensa shadow
The world doesn't need a billion geniuses. It needs people who are capable, reliable, and empathetic.
If your score is nowhere near Mensa, you are in good company. You are in the company of the people who build the world, fly the planes, perform the surgeries, and raise the families. You have the cognitive "hardware" to handle the complexities of modern life.
Don't let a percentile ranking keep you from pursuing a difficult degree or a complex career. The "Genius" gatekeepers aren't as powerful as they seem.
The next time you see a post about a 5-year-old with a 160 IQ, just smile and go back to your work. Success is built on what you do with the brain you have, not the score you were assigned on a Tuesday afternoon in a testing center.
Actionable Steps for Cognitive Growth:
- Identify your "Cognitive Leaks": Are you losing "smart points" to anxiety, poor diet, or lack of sleep? Fix the biology first.
- Skill Stack: Instead of trying to be the top 1% in one thing, try to be the top 20% in three unrelated things. The intersection of those skills is where true "genius" (and value) happens.
- Practice Deep Work: Intelligence is often just the ability to focus. Train your attention span like a muscle. Start with 20 minutes of undistracted work and build up.
- Read broadly: Crystallized intelligence—your storehouse of knowledge—increases with age and exposure. Feed your brain better data.
Intelligence is a tool, not a trophy. Use it.
