What Is a Good IQ Score? How to Actually Read Your Results
You just got your number back, and now you're staring at it wondering what it actually means. So — what is a good IQ score? The short answer: anything above 100 is above average, anything above 115 is genuinely uncommon, and anything above 130 puts you in roughly the top 2% of the population. But that's the bumper-sticker version, and if you've taken a test seriously, you deserve a better answer than that.
Let's break down what the numbers really say, where they fall short, and how to interpret your own result without either overinflating it or selling yourself short.
The Standard IQ Score Distribution
IQ tests are designed around a normal distribution — the classic bell curve — with a mean of 100 and a standard deviation of 15. That's not arbitrary. It's the scaling that makes the scores comparable across populations and across tests like the WAIS, Stanford-Binet, and Raven's Progressive Matrices.
Here's how the curve actually breaks down:
- Below 70 — roughly 2% of people. Historically classified as significantly below average.
- 70–84 — about 14%. Below average.
- 85–114 — about 68%. The average range. Most people live here.
- 115–129 — about 14%. Above average; "high average" to "superior."
- 130–144 — about 2%. Gifted range.
- 145+ — under 0.1%. Highly gifted to exceptional.
So if you scored 122, you're not in Mensa territory, but you're sharper than roughly 93% of the population. That's not nothing.
What Is a Good IQ Score, Really?
Here's where most articles get lazy and just say "above 100 is good." Technically true, statistically meaningless. A score of 101 is essentially identical to 99 — within the margin of error of almost any test you'll take.
A more useful framework:
- 100–110: Solidly average. You can handle most cognitive tasks the modern world throws at you.
- 110–120: Above average. You'll find most academic and professional work tractable, sometimes easy.
- 120–130: Notably high. This range correlates strongly with success in cognitively demanding fields — law, medicine, engineering, research.
- 130+: Gifted. Rare enough that you've probably noticed since childhood that you process certain things faster than peers.
But here's the catch: a "good" IQ score depends on what you're measuring it against. Good for getting through university? 115 is plenty. Good for theoretical physics research? You're probably looking at 130+. Good for being a thoughtful, capable adult? Honestly, IQ matters far less than people pretend once you clear the average threshold.
Why a Single Number Misses the Point
This is where I'll be blunt: a single IQ score is a compressed summary of something genuinely multidimensional. Two people with identical scores of 125 can have completely different cognitive profiles. One might dominate verbal reasoning and struggle with spatial tasks. The other might be a pattern-recognition machine who can't write a clear paragraph to save their life.
Modern cognitive assessment recognizes at least these distinct dimensions:
- Verbal reasoning — language, vocabulary, comprehension
- Logical/abstract reasoning — pattern recognition, deduction
- Numerical reasoning — quantitative manipulation
- Spatial reasoning — mental rotation, visualization
- Working memory — holding and manipulating information
- Processing speed — how fast you execute cognitive operations
Your composite score smooths all of these into one number. That's useful for population statistics. It's almost useless for understanding yourself. If you scored 120 overall but your spatial reasoning is at 140 and your processing speed is at 105, that's the actually informative finding — not the headline number.
This is why a profile-based test matters more than a single-number test. IQ-Wiz is built specifically around this idea: instead of handing you a number and a percentile, it produces a full cognitive profile across multiple dimensions, so you can see where your mind actually has horsepower and where it doesn't.
What a Good IQ Score Doesn't Tell You
Worth saying out loud: IQ predicts certain things well and other things terribly.
It predicts reasonably well: academic performance, ability to learn complex material quickly, performance on cognitively demanding jobs.
It predicts poorly: creativity, emotional intelligence, conscientiousness, persistence, social skill, wisdom, whether you'll be happy, whether you'll be successful in any holistic sense.
The research on life outcomes is consistent — once you're above roughly 120, additional IQ points have rapidly diminishing returns. A 145 doesn't beat a 125 at most things that matter. Conscientiousness, grit, and how you actually deploy your cognitive resources tend to outpace raw IQ as predictors of long-term success.
Which leads to a more interesting question than "what's a good score?" — namely, how do you actually work? IQ tells you what your engine can do under controlled conditions. It doesn't tell you when you're motivated, how you handle ambiguity, or what kind of problems you naturally gravitate toward. For that, something like archetypes.work is more useful — it maps how you operate in real working contexts, which is often more actionable than a cognitive score.
How to Interpret Your Own Result
A few honest rules of thumb:
- Take the percentile more seriously than the number. "Top 10%" tells you something concrete. "118" is just a label on that.
- Look at sub-scores if you have them. Your strengths and weaknesses are more informative than the average.
- Don't retake until you forget the questions. Practice effects can inflate scores by 5–10 points and tell you nothing new.
