Can You Actually Measure Intelligence? The IQ Test Scam Nobody Talks About

Here’s a fun party trick: tell someone your IQ score and watch their face. If the number is high, they’ll treat you like you just admitted to being a secret wizard. If it’s low, well, you probably won’t be telling anyone.

But here’s the thing nobody seems to ask: what exactly did that test measure?

The Origin Story Nobody Requested

The IQ test was invented in 1905 by a French psychologist named Alfred Binet. His goal was modest and specific — he wanted to identify kids in Paris schools who needed extra help with their studies. That’s it. Not to rank all of humanity on a cosmic intelligence ladder. Not to determine who deserves a scholarship or who should run a country.

Binet himself was pretty clear about this. He said his test did not measure “innate intelligence” and warned that the scores should not be used to label people permanently. He literally said the scale was not designed for that purpose.

So what happened? America happened.

How America Turned a School Tool Into a Sorting Hat

When the IQ test crossed the Atlantic, it got a glow-up it never asked for. Henry Goddard translated Binet’s test into English and immediately started using it to classify immigrants at Ellis Island. In 1913. On people who didn’t speak English. Taking a test in English.

Shockingly, many of them scored poorly.

This was then used as “evidence” that certain ethnic groups were intellectually inferior. The U.S. Army picked up the trend in World War I, mass-testing recruits with the “Army Alpha” and “Army Beta” tests. The results were used to assign ranks, and the data was later cited by eugenicists to argue for immigration restrictions.

So from day one, IQ tests in America were tangled up with some genuinely ugly politics. A tool designed to help kids learn was weaponized to sort people into categories of “worthy” and “unworthy.” Not a great start.

What IQ Tests Actually Measure

Modern IQ tests — the Wechsler Adult Intelligence Scale (WAIS) and the Stanford-Binet — are significantly better designed than those early versions. They test things like:

• Working memory: Can you hold information in your head and manipulate it?
• Processing speed: How quickly can you match symbols or scan for patterns?
• Verbal comprehension: Can you define words, see similarities between concepts?
• Perceptual reasoning: Can you solve visual puzzles, spot patterns in shapes?

These are real cognitive abilities, and they do correlate with some real-world outcomes. People with higher IQ scores tend to do better in school, earn more money, and live longer (though that last one is probably more about socioeconomic factors than raw brainpower).

But here’s where the scam comes in: IQ tests measure a narrow slice of cognitive ability and then present the result as if it captures the whole pie.

That’s like testing someone’s ability to sprint 100 meters and then declaring their “overall athletic score.” Sure, speed matters. But what about endurance? Coordination? Flexibility? Strategy?

The Flynn Effect: Everyone’s Getting “Smarter”

One of the weirdest things about IQ scores is the Flynn Effect, named after researcher James Flynn. He discovered that average IQ scores have been rising steadily — about 3 points per decade — across virtually every country tested.

Does that mean your grandparents were dumber than you? Almost certainly not. What it likely means is that we’ve gotten better at the specific types of thinking that IQ tests measure. We’re more used to abstract reasoning, pattern matching, and test-taking in general. We live in environments saturated with symbolic information — screens, signs, data — that previous generations didn’t have.

The Flynn Effect is basically proof that IQ scores reflect training and environment as much as they reflect some fixed “intelligence.” If IQ were purely genetic, scores wouldn’t have risen so dramatically in just a few generations. Evolution doesn’t work that fast.

The Stuff IQ Tests Miss Entirely

Here’s a short list of things that most people would consider part of “intelligence” that IQ tests completely ignore:

• Creativity: Can you generate novel ideas? IQ tests don’t ask.
• Emotional intelligence: Can you read a room, manage your emotions, or navigate social dynamics? Not measured.
• Practical intelligence: Can you fix a car engine, negotiate a raise, or figure out a subway map in a foreign city? Irrelevant to your score.
• Musical and artistic ability: Some of the most complex cognitive processing humans do, and IQ tests have nothing to say about it.
• Wisdom: Knowing what to do with knowledge is arguably more important than the knowledge itself.

Harvard psychologist Howard Gardner proposed the theory of multiple intelligences in the 1980s — linguistic, logical-mathematical, spatial, musical, bodily-kinesthetic, interpersonal, intrapersonal, and naturalistic. IQ tests basically cover the first two and half of the third. That’s like grading a restaurant based only on the bread basket.

The Real Problem: We Turned a Number Into an Identity

The biggest issue with IQ isn’t the tests themselves. It’s what we’ve done with them culturally. We’ve created a society where people genuinely believe a single number can capture their intellectual worth. Where kids get tracked into “gifted” or “remedial” programs based on one test, taken on one day, possibly while they were hungry or anxious or just didn’t care.

The number becomes a story people tell about themselves. “I have a high IQ” becomes a personality trait. “I scored low” becomes a ceiling on ambition.

Meanwhile, the actual research shows that IQ scores can change over time, that they’re influenced by nutrition, education, stress, and sleep, and that they predict far less about life success than people assume.

Motivation, grit, curiosity, social connections, and plain old luck matter enormously. A 130 IQ with zero follow-through will lose to a 100 IQ with relentless work ethic almost every time.

So Should You Take an IQ Test?

Sure, if you find it fun. Treat it like a brain teaser — a puzzle that tells you something about how your brain handles certain kinds of problems. Enjoy the process.

But if you’re taking it to prove something about your worth as a human being? Save yourself the time. That’s not what these tests do, it’s not what they were designed to do, and it’s not what the science supports.

Alfred Binet would probably agree. He just wanted to help some kids in Paris. The rest of this mess? That’s on us.
