You just got your score back. Maybe it’s a 112. Maybe it’s a 135. Most people look at that number and think they’ve found the "speedometer" for their brain, but the reality is way messier. Most of what you see on social media regarding an iq test results scale is honestly just fluff. People treat it like a video game stat. High intelligence? You’re a genius. Low? You’re stuck. That’s not how the psychometrics actually work, and if you're looking at a raw number without understanding the bell curve, you're missing the entire point of the assessment.
Most modern tests, like the Wechsler Adult Intelligence Scale (WAIS-IV), don't even aim for a "perfect score." They aim for a median. That median is 100. If you score a 100, you are exactly at the center of the population. But let's get into the weeds because the "normal" range is wider than you think.
The Standard IQ Test Results Scale is a Bell Curve
Stop thinking of it as a ladder. It’s a hump.
In professional psychology, we use something called "standard deviation." For most IQ tests, one standard deviation is 15 points. This is crucial because it defines the "Average" bracket. If you fall between 85 and 115, you are statistically average. That covers about 68% of the entire human population. It's a massive group. You’ve got doctors in this range, and you’ve got people who struggle to change a tire. It’s broad.
Then you have the "High Average" (110–119) and "Superior" (120–129) brackets. Once you cross that 130 mark, you’re in the top 2% of the population. This is the "Gifted" threshold. But here is the kicker: being "Gifted" on an iq test results scale doesn’t mean you’re better at life. Lewis Terman, a pioneer in educational psychology at Stanford, started a famous long-term study in 1921 following high-IQ kids (nicknamed "Termites"). What did he find? Many of these "geniuses" grew up to have very ordinary careers. Some became lawyers, sure, but others were clerks or salesmen. IQ measures potential for specific types of cognitive processing, not "success."
Why 100 is the Magic Number
The scale is designed to re-center itself. This is known as the Flynn Effect. Named after researcher James Flynn, it’s the observation that raw scores on IQ tests have been rising globally for decades. Because we keep getting "smarter" (or at least better at taking tests), psychometricians have to keep making the tests harder to ensure 100 remains the average. If you took an IQ test from 1950 today, you'd probably score significantly higher than the people back then. But that doesn't mean you're a biological super-genius compared to your grandfather; it just means our environment is more "cognitively demanding" now. We deal with more abstractions, more symbols, and more complex logic in our daily lives.
What the Numbers Actually Represent
Let's break down the tiers. Not with a boring chart, but with what these levels actually look like in the real world.

- 70 and below: This is generally the threshold for identifying intellectual disabilities, though clinical diagnosis requires looking at "adaptive functioning" (how well you handle daily life) too.
- 85 to 115: The "Average" meat of the curve. Most school systems and workplaces are designed specifically for people in this range.
- 115 to 130: Often called "Bright." These individuals usually find university-level work manageable and can synthesize complex information relatively quickly.
- 130 to 145: "Gifted." This is Mensa territory. You're looking at roughly 1 in 50 people.
- 145 to 160: "Highly Gifted." We are talking 1 in 1,000 territory.
- 160+: This is the stratosphere. Think Stephen Hawking or Judith Polgar. At this level, the iq test results scale actually starts to break down because there aren't enough people in the world to create a statistically reliable comparison group.
Is a 140 better than a 120? Statistically, yes. In practice? It depends on "Cognitive Proficiency." A high score in verbal reasoning doesn't help you if your "Processing Speed" (how fast you can actually perform mental tasks) is low. Many people have "jagged profiles" where they are geniuses in one area and totally average in another.
The Myth of the "General" Intelligence
We call it g factor. It's the idea that if you're good at one mental task, you're likely good at others. Charles Spearman came up with this over a century ago. While g is a real statistical phenomenon, the iq test results scale often hides the nuances.
Take the Woodcock-Johnson tests or the Stanford-Binet. They divide your score into sub-sections. You might have a 140 in "Fluid Reasoning" (solving new problems) but only a 95 in "Working Memory" (holding info in your head). On paper, your Full Scale IQ (FSIQ) might look like a 120. But that 120 is an average of two very different numbers. You’d feel like a genius when solving puzzles but feel "dumb" when trying to remember a grocery list.
This is why "Total IQ" can be a bit of a lie. It's a composite. It's like saying a car is "average" because it has a Ferrari engine but the brakes of a tricycle.
Does Your Score Change?
Kinda. For adults, IQ is remarkably stable. If you take a proctored test at age 25 and another at age 45, your score will likely be within a few points of each other. However, for kids, it’s a total craffshoot. Brains develop at different speeds. A child might score a 130 at age 7 and a 110 at age 15. This is why "Gifted and Talented" programs in schools can be so controversial—they often label kids based on a snapshot of a moving target.
Where People Get Scammed
If you took an IQ test on a website that had "pop-up" ads or asked for $20 to see your "certified" results, I hate to tell you this: it's fake. Real IQ tests, like the WAIS or the Raven’s Progressive Matrices, are administered by trained psychologists. They take hours. They involve blocks, picture completion, and verbal vocabulary tests.
Online "tests" usually use a skewed iq test results scale to make you feel good so you'll share the result on Facebook. They "norm" the test against other people who took the online test—people who are probably motivated to score high. A real test compares you against a representative sample of the entire population, including people who hate tests and people who didn't finish high school.
The Limitations of the Scale
We have to talk about E-E-A-T here—Expertise, Authoritativeness, and Trustworthiness. Psychometricians like Dr. Howard Gardner have long argued that IQ is too narrow. Gardner’s "Multiple Intelligences" theory suggests we should measure musical, kinesthetic, and interpersonal intelligence too. While the scientific community still leans heavily on the iq test results scale because it's the best predictor we have for academic success, it definitely doesn't measure "wisdom" or "creativity."
You can have a 150 IQ and be a total jerk who can't hold a job. You can have an 85 IQ and be the most reliable, kind, and socially successful person in your town. The scale measures the "machinery" of the brain, not the "driver" of the car.
Cultural Bias and History
It’s impossible to discuss the IQ scale without acknowledging its dark history. In the early 20th century, these scales were used by eugenicists to justify forced sterilizations and restrictive immigration laws. Early tests were heavily biased toward white, Western, middle-class knowledge. If a test asks you to identify a "saucer," and you’ve never seen a tea set, you aren't "less intelligent"—you just don't have the cultural context. Modern tests try to fix this with non-verbal sections, but the debate about bias is still very much alive in academic circles.
Actionable Steps: What to Do With Your Result
So, you have a number. What now?
First, look at the percentile. That's more useful than the number. If you're in the 90th percentile, you're smarter than 90 out of 100 people. That's a clear metric.

Second, don't let the score become a self-fulfilling prophecy. If you score high, don't stop working hard thinking you're "naturally" better. Carol Dweck’s research on "Growth Mindset" shows that people who believe intelligence is fixed (which high IQ scores can trick you into believing) often give up faster when they hit a wall.
Third, if you’re concerned about a low score, look at your "Executive Functioning." Often, what looks like a lower IQ is actually just ADHD or a learning disability like dyslexia. These don't mean you lack intelligence; they mean your "input/output" system has a glitch.
Final Practical Insight
If you really want to understand your brain, stop looking for a single number. Ask for the index scores.
- Verbal Comprehension: How well you understand and use language.
- Perceptual Reasoning: How well you visualize and solve non-verbal problems.
- Working Memory: Your mental "scratchpad."
- Processing Speed: How fast your brain "clocks" information.
Understanding the balance between these four is ten times more valuable than knowing if you're a "115" or a "120" on a generic scale. Use the results to find your "cognitive workarounds." If your memory is weak but your reasoning is high, take notes constantly and lean on your logic to fill in the gaps. That’s how you actually use an IQ test to improve your life.
Stop obsessing over being a "genius." Most of the world is run by people with 110 IQs who just showed up every day and worked hard. Persistence beats a high-percentile score every single time.
Next Steps for You: If you’ve taken a professional test, request the full psychological report, not just the summary. Look for the "Scatter"—the difference between your highest and lowest subtest scores. If there’s a gap of more than 15-20 points between indices, you should talk to a specialist about "Twice Exceptionality" (2e), which is when someone is gifted but also has a learning difference. Understanding that gap is the key to unlocking your actual potential, rather than just staring at a number on a bell curve.
