The Problem in the Cockpit
In the 1940s, the U.S. Air Force faced a disturbing pattern. Skilled pilots, flying well-maintained aircraft, were losing control mid-flight. Crashes were happening during routine operations. No one could explain why.
At first, investigators blamed the pilots. Then the equipment. Then training. But none of these were consistent across incidents.
Eventually, they looked at the cockpits themselves. Every switch, lever, and seat had been designed to fit the “average” pilot – based on data collected decades earlier on things like height, arm length, and chest size.
It seemed logical. If you design for the average, you serve the most people.
But when researchers remeasured more than 4,000 pilots across ten key body dimensions, they discovered something staggering: not a single pilot matched the average on all measurements. In fact, if you selected even just three dimensions — say, height, arm length, and torso — fewer than five percent of pilots fit the average range on all three.
The result? Cockpits that fit no one.
Designing for the average had compromised safety, performance, and lives.
The solution was revolutionary: adjustable cockpits. Instead of forcing pilots to fit the design, the design adapted to fit the pilots. Once they stopped designing for the average, both safety and performance improved dramatically.
This story is detailed in The End of Average by Harvard researcher Todd Rose (2016), who uses it to expose a larger truth: when we design for the average in any human system, we fail most people.
So here’s the question:
If aviation figured this out more than 70 years ago, why haven’t schools?
Where the Myth Began: The Birth of the “Average”
This idea of the “average” student didn’t originate in education. It came from astronomy.
In the early 1800s, Belgian astronomer Adolphe Quetelet grew frustrated with his inability to gain recognition through his astronomical work. So he turned his mathematical expertise away from the stars and toward something closer to Earth: people!
Using the same statistical tools he had applied to planetary motion, Quetelet began measuring human characteristics – height, weight, criminal records, even moral behavior. When he plotted this data, he saw a familiar shape: the bell curve.
At the center of that curve sat what he called l’homme moyen – the average man. But Quetelet made a subtle and dangerous leap. He didn’t just use the average as a statistical midpoint. He defined it as an ideal. A standard of normalcy. A model of how people should be.
Deviation from the average, in Quetelet’s view, wasn’t just difference. It was error. Outliers were flaws to be corrected, not variations to be understood.
That idea would go on to shape medicine, economics, and eventually, education — where it would become not just a method of measurement, but a foundation for design.
Galton: Ranking Human Worth
Francis Galton, a British polymath and cousin of Charles Darwin, took Quetelet’s concept and ran with it – toward something darker.
As Rose describes, Galton wasn’t content with studying averages. He wanted to rank people. By intelligence. By beauty. By “worth.”
He invented the field of eugenics and believed that only the “best” people should reproduce. He used statistics to justify social hierarchies, arguing that heredity determined success or failure – and that society should engineer human evolution.
Galton’s legacy gave us IQ tests, racial pseudoscience, and dangerous policies rooted in the belief that some people are more valuable than others.
He turned statistics into a weapon to judge, divide, and control.
Taylor: Turning Humans into Machines
While Galton ranked people, engineer Frederick Winslow Taylor sought to control them.
Rose also highlights, Taylor developed the theory of scientific management. To him, the ideal worker was efficient, obedient, and interchangeable. Human variability was waste.
He once wrote, “In the past the man has been first. In the future the system must be first.”
Taylor believed workers shouldn’t think – they should follow. His methods were rooted in a classist view: managers think, workers obey.
Public education leaders took note. As schools expanded in the early 20th century, they needed a model that could scale. Taylorism offered a blueprint.
They didn’t choose the path of humanist education – one that honors curiosity, individuality, and growth. That was too slow. Too expensive.
They chose Taylorism.
When Schools Became Factories
According to Rose, early 20th-century school leaders adopted Taylor’s ideas to build an education system that mirrored factories:
- Students were grouped by age, not readiness.
- Bells dictated the schedule, like factory shifts.
- Teachers delivered a one-size-fits-all curriculum.
- Standardized tests sorted and ranked children.
- Curriculum guides focused on coverage over understanding.
Variation was treated as deviation.
Difference was treated as deficiency.
The system didn’t adjust to the learner.
The learner was expected to adjust to the system.
The Myth That Still Guides Us
“There is no such thing as an average student.”
— Todd Rose
Despite all we know from neuroscience, psychology, and lived experience, schools continue to operate as though the mythical average student is real.
Harvard researcher Todd Rose introduced the idea of the jagged profile. Every learner has a unique combination of strengths, challenges, and interests. No one is equally strong across all areas, and no one fits the mold completely.
And yet, our systems continue to teach to the middle. They reward students who comply with standard expectations and penalize those who diverge.
This is not just outdated. It is harmful.
We are not ignoring individuality. We are actively suppressing it.
What We Are Losing
Designing for the average strips away the very qualities schools should cultivate:
- Curiosity is replaced by coverage.
- Creativity is flattened by conformity.
- Depth is sacrificed for speed.
- Purpose is reduced to performance.
- Identity is shaped by a system that says: “Fit in, or fall behind.”
Students learn to measure themselves against a model that was never real. They disengage not because they do not care, but because the system was never built with them in mind.
And the longer we pretend otherwise, the more they believe that something is wrong with them.
A Different Future Is Possible
The system isn’t broken. It’s doing exactly what it was built to do.
That’s the problem.
It was built to sort, rank, and control.
To reward uniformity.
To confuse fairness with sameness.
But fairness is not sameness. Fairness means recognizing that every student needs something different to thrive.
So what if we built schools differently?
Not schools that personalize within a broken model.
But schools that are rebuilt from the ground up – to honor complexity, nurture curiosity, and celebrate difference.
Let’s stop preparing kids for Taylor’s factory floor.
Let’s stop sorting students with Galton’s tools of ranking and exclusion.
Let’s stop mistaking compliance for success.
The average doesn’t exist.
It’s time we stopped designing schools as if it does.
