Do NT-Designed IQ Tests Truly Reflect Neurodivergent Intelligence?

[GHA]

I’ve lived long enough alongside a neurodiverse mind to know that raw intelligence is not a single, neat number. And yet, most of the world still tries to measure it that way — with IQ tests almost always designed, standardised, and interpreted by NT frameworks.
This raises a question I’ve been asking for years: Do those tests truly capture the intelligence of a neurodivergent person, or do they mostly reflect how well someone can think like an NT for the duration of the exam?
From what I’ve seen, the gap isn’t in ability — it’s in alignment. Many neurodiverse people I’ve known can excel at pattern recognition, deep analysis, systems thinking, or creative problem-solving far beyond NT averages. But IQ tests often emphasise speed over depth, standardised logic over unconventional leaps, and a narrow set of problem types over the broad spectrum of ways a human mind can operate.
That means a neurodivergent person can score lower than their true capability simply because the test doesn’t map to how their brain processes information. In some cases, the opposite can happen — a high score that hides challenges in applying that intelligence to certain real-world scenarios. Either way, the number doesn’t tell the whole story.
In my son’s case, and in many others I’ve observed, the strengths that make them exceptional — the ability to hyperfocus, to see connections no one else notices, to hold complex ideas in their head and work on them for days — are not rewarded in a timed, one-size-fits-all IQ format. And yet, those same abilities are exactly what allow them to create value in the real world.
This is why I’ve always believed that while IQ tests can offer some insights, they’re a narrow lens. They reflect how well you can navigate the test-maker’s map, not the full territory of your mind. And if that map was drawn by NTs, it will inevitably carry their assumptions about what intelligence looks like.
So I’d ask: if you’ve taken an IQ test, did you feel it truly reflected your abilities? Or did it measure something else — perhaps your ability to “translate” your thinking into NT terms quickly enough to fit their scoring system?
Because in my view, the real measure of intelligence is not a number on paper, but the ideas, solutions, and insights you bring into the world. And that’s something no stopwatch or answer key can fully capture.

This matches my own thoughts. When I was 14 the school put me through a series of IQ tests. There were ten separate tests a week apart, each had 200 questions on a wide range of different types of logical problems, and the tests were against a 20 minute clock. No one was expected to fully complete a test, how much you managed affected the scoring.

I scored 172, but as I was doing those tests I realised that my sister would have really struggled with those tests and would have been lucky to score somewhere in the 90s, yet she's far more intelligent than most people realise. She always played at being the dumb blonde but nothing could be further than the truth. (all of us kids grew up with trust issues)

Absolutely!! Sir!!

'While the terms “high IQ” and “giftedness” are often used interchangeably, they represent distinct, nuanced concepts with areas of overlap. There is no single, agreed-upon definition for either term, so this exploration draws on a mix of research, existing literature, and my own experience working with exceptionally bright and intense individuals. By exploring these nuances, we can start to appreciate the multifaceted nature of extraordinary minds.'

Gifted Neurodivergent: High IQ vs. Gifted and Why It Matters

A flaw in the testing method I described above:

As a kid I loved maths tests. There was never any danger of me scoring less than 100%, for me it was always a personal contest - how quickly I could finish. And I developed methods for this. The most important of these was to flip through the test and answer all the easy and obvious questions first.

In an IQ test against the clock with 200 questions this gave me a distinct advantage.

Odd to think when I took IQ tests twice in my life I never contemplated the time element and how it impacts the results. But then I never really saw the usefulness of this metric outside of a medical professional's assessment or approval into Mensa.

Not something normally connected with any aspect of most job interviews, though I did have one hiring process where they were aware of my IQ...(and everything else) for better or worse. The most invasive employment process I ever experienced.

Though at the time neither myself nor the employer or my own physicians were aware of my autism.

Gifted Neurodivergent: High IQ vs. Gifted and Why It Matters

Thank you, Judge, for your kindness in attaching a link to the article. I may agree with some aspects, but I largely have a different viewpoint.
The article draws a line between “high IQ” and “giftedness,” but I believe that line is far less clear — especially when it comes to neurodivergent people. IQ tests are created and standardised through NT thinking. They measure certain types of reasoning and speed within that framework, but they do not capture the full spectrum of how a neurodivergent mind operates.
I have lived decades alongside a neurodivergent mind. I have seen abilities that simply do not appear in timed, structured testing: extraordinary pattern recognition, deep sustained focus, original solutions that reframe the problem entirely, and an ability to connect concepts others would never think to link. These are not side traits — they are the core of that person’s intelligence.
When you measure someone only by NT standards, you often end up measuring how well they can translate their thinking into that system — not the true strength of their mind. That’s why I see IQ as, at best, a partial indicator. The rest of the picture can only be seen in real-world output: the ideas, creations, and problem-solving they bring when allowed to work in their own way.
Giftedness in neurodivergence is rarely neat or uniform. It comes with peaks and troughs, but the peaks can be extraordinary. If we rely too heavily on tools built for a different cognitive style, we risk missing the very brilliance we claim to be measuring.

I just find the entire metric relatively meaningless to people regardless of how intelligent a consensus of society might envision them. As if it was more akin to vanity accessory. My bad...

Frankly I have greater interest in a what is known as an "Emotional IQ", particularly regarding autistic persons.

Odd to think when I took IQ tests twice in my life I never contemplated the time element and how it impacts the results.

I had only completed a few of those tests when I began to feel that they were completely useless in any real world sense, and I was only 14 at the time. I also figured that all of my school grades were completely irrelevant and that my successes or failures would be judged on my own merits on the day regardless. That turned out to be true.

Then the student counsellor that ran the tests molested me and I overheard my father talking about sending me to a special school, a boarding school. That means I'd be trapped, no escape. No thank you. I wanted nothing more to do with school after that. I stopped going completely except for exam week where I still always got straight As. As soon as I was 16 I was out of there.

I thought I'd put that behind me but things have a way of coming back later in life. When I was in my early 40s and burning out badly and looking for a different path in life I looked at going to uni. Because I had been unemployed for more than 6 months the government would pay for that for me as well as I'd get student benefits. I was tested for prior knowledge as I didn't finish high school but I passed that no worries and got accepted for a 6 year full time course in Computer Science that would earn me a PhD.

That was great, right up until the first day I was expected to attend. I couldn't make myself do it. I stayed home depressed and confused and that was pretty much the final straw in my burn out. That's when I lost it completely and ran off in to the rain forests.

It wasnt until my late teens that , learned that there was a method to a tual test taking thst NT did. My Iowa basics IQ test at 7 years old almost stymied me .Completely had no idea of how to complete a test of this kind. And there was no instruction of how to even mark ,which answer was correct. Most of the time spent on the test was figuring out how or where to put the mark for the correct answer . Then was not informed of a time limit,so I would focus on each question quite deliberately. To get the correct answer, interpolation of each question. Each individual Aspie maybe better suited to a different method of learning that might suite their learning skills . Regardless my teachers had informed my mother that I was performing below my skill levels in school . If I hadnt been under daily abuse at home and bullying and non inclusivity,and outright ostracizing of me in school by others.Might have done better .

Might have done better .

My sister had the same sorts of problems, it didn't stop her from having a successful life though. She was incredibly smart, just not academically inclined.

Sounds like my NT brother as well. He fared far less than I did existing in the same military family and somewhat "rigid" environment. Though in his case much of his issues involved a lack of self-discipline and laziness. Education requiring structure he didn't care for, in spite of his intellect.

And watching my brother occasionally take a beating from our father did wonders to keep me on the right track in comparison. Funny how different we are having grown up with the same parents in the same household.

So I’d ask: if you’ve taken an IQ test, did you feel it truly reflected your abilities?

Yes. I get very high IQ scores and it is reflected in my abilities.

My thoughts are exaclty the opposite, that the IQ test format is very much in line with autistic minds, this is why famously all the highest IQ scores belong to high functioning autistics.
