The Myth of Average: Todd Rose at TEDxSonomaCounty

Reviewer: Queenie Lee Host: Please welcome
to the TEDxSonomaCounty stage, Todd Rose. (Applause) Todd Rose: It’s 1952,
and the Air Force has a problem. They’ve got good pilots
flying better planes, but they’re getting worse results. And they don’t know why. For a while, they blamed the pilots. They even blamed the technology. They eventually got around
to blaming the flight instructors. But it turned out that the problem
was actually with the cockpit. Let me explain. Imagine you’re a fighter pilot. You’re operating a machine that in some cases can travel faster
than the speed of sound, and where issues
between success and failure, sometimes life and death, can be measured in split seconds. If you’re a fighter pilot, you know that your performance depends fundamentally
on the fit between you and your cockpit. Because after all, what good
is the best technology in the world, if you can’t reach
the critical instruments when you need them the most? But this presents a challenge
for the Air Force. Because obviously,
pilots are not the same size. So, the issue is: how do you design one cockpit
that can fit the most individuals? For a long time, it was assumed that you could do this
by designing for the average pilot. That almost seems intuitively right. If you design something
that’s fit for the average sized person, wouldn’t it fit most people? It seems right but it’s actually wrong. And 60 years ago, an Air Force researcher, Gilbert Daniels, proved to the world
just how wrong this really is, and what it was costing us. Here’s how he did it. He studied over 4,000 pilots and he measured them
on ten dimensions of size, and he asked a very simple question: how many of these pilots
are average on all ten dimensions? (Laughter) The assumption was
that most of them would be. Do you know how many really were? Zero. Gilbert Daniels proved there was no such thing
as an average pilot. Instead, what he found was that every single pilot
had what we call a jagged size profile. Right? It means no one is the same
on every dimension. And this makes sense. Just because you’re the tallest person doesn’t mean you’re the heaviest, doesn’t mean you have
the broadest shoulders, or the longest torso. But this is tricky because if every pilot
has a jagged size profile and you design a cockpit on average, you’ve literally designed it for nobody. So, the Air Force
realized they had a problem. And their response was bold. They banned the average. (Laughter) Meaning that moving forward, they refused to buy fighter jets where the cockpit was designed
for an average sized pilot. And instead, they demanded
that the companies who built these planes designed them to the edges
of dimensions of size. Meaning that rather than design
for, say, the average height, they wanted a cockpit
that could accommodate as close to the shortest pilot
and the tallest pilot as the technology would allow. Now, the companies that made these planes,
as you could imagine, weren’t happy, right? They argued, and lobbied, and they said, it’s going to be impossible
or at least impossibly expensive to build a flexible cockpit. But once they realized
that the Air Force wasn’t going to budge, suddenly, it was possible. And it turned out
it wasn’t that expensive. And in fact, they made great strides leveraging simple solutions that we all take for granted
in our everyday life, like adjustable seats. And as a result, the Air Force not only improved the performance
of the pilots that they already had, but they dramatically
expanded their talent pool. And today, we have the most diverse
pool of fighter pilots ever. But here’s the thing, many of our top pilots would have never
fit in a cockpit designed on average. So, most of us have never sat in the cockpit of a $150 million
fighter jet, right? But we’ve all sat in the classroom. And I would argue (Laghter) (Applause) I would argue that these are
the cockpits of our economy, and I think we all know
that we have some problems. We’re spending more money
than ever before, but we’re getting worse results. Whether we’re talking about
declining test scores in math and science or our dropout crisis. You probably know, that we have over 1.2 million dropouts every single year
in high school in this country. What you may not know is that at least 4% of those dropouts
are known to be intellectually gifted. That means we’re losing over 50,000
of our brightest minds every single year. So, we know we have a problem. But do we know why? So far, we’ve been content
to blame the students. We blame the teachers. We even blame the parents. But here’s the thing … I think back to the Air Force example, and I can’t help but wonder: how much of this problem
is just bad design? Here’s what I mean. Even though we have
one of the most diverse countries in the history of the world, and even though it’s the 21st century, we still design our learning environments, like textbooks, for the average student. No kidding. We call it age-appropriate. And we think it’s good enough. But of course, it’s not. I mean, think about it. What does it even mean
to design for an average student? Because a student is not one-dimensional, like struggling to gifted. Students vary on many
dimensions of learning, just like they vary on dimensions of size. Here are a few obvious ones. And just like size, each student, every single one of them, has a jagged learning profile. Meaning, they have strengths, they’re average at some things, and they have weaknesses. We all do. Even geniuses have weaknesses. But … if the fighter pilot example
has taught us anything, it’s this. If you design those
learning environments on average, odds are you’ve designed them for nobody. So, no wonder we have a problem. We’ve created learning environments
that because they are designed on average, cannot possibly do
what we expected them to do, which is to nurture individual potential. But think about
what that could really costs us. Because every single student
has a jagged learning profile, it means that the average hurts everyone, even our best and brightest. Even for them, designing on average
destroys talent in at least two ways. First, it makes your talent a liability. We all know kids like this. So unbelievably gifted in one area that their educational environment
can’t challenge them. We also know what happens. They get bored, and a shockingly
high number of them drop out. The second way that designing on average destroys talent is that it means your weakness
will make it hard for us to see, let alone nurture, your talent. We all know kids like this as well. Like the kid who’s gifted in science
but who is a below average reader. Because our science textbooks assume that every kid
is reading at grade level, this kid’s in trouble. Because for her, science class is first
and foremost a reading test. And it’s doubtful that we will ever see
what she’s truly capable of. Now, it’s one thing when our technology does not allow us to do anything
other than average. But it is a whole other thing when the technology changes
and we can do more, but we don’t realize it. That’s where we are today. In the last few years, education,
just like the rest of society, has gone digital. If you don’t believe me,
just consider this fact: U.S. public schools are one of the largest
buyers of iPads in the world. Right? So, the question isn’t
do you want the technology? It’s already here.
You’ve already paid for it. The question is:
what do you want it to be? And this is where it really gets exciting. We have a chance, right now, to use this technology
to create learning environments that are so flexible that they truly can nurture the potential
of every single individual. Now, you might think
that sounds expensive, right? Doesn’t have to be. In fact, we can get a long way, we can make great strides
with simple solutions that we take for granted
in our everyday digital lives. Here I am thinking about basic stuff like language translation,
support for reading, vocabulary, you know, even the ability of a machine
to pronounce a word for you, or read a passage if you want. Basic stuff. But while these are simple solutions, you’ll be surprised at how big of an impact they actually have
on the lives of individuals. I know I was, the first time
that I saw it happen. I was observing a fourth-grade classroom a few years ago, and they were participating in a study where we were testing the effectiveness
of a new digital science curriculum. Now, I’ll be the first to say this new digital version wasn’t fancy. In fact, it was pretty basic. The thing that it had going for it though, was that it did not assume that every student in that classroom
was reading at grade level. Now, one of my favorite things
about this particular classroom was the teacher. Because she hated technology. And I know this because it’s the first thing
that she told me when I met her. And my response was, “OK, why did you sign up for a study
that’s about technology?” She told me she was willing to go through this in the hopes that it might help
one kid in her class. His name was Billy. And Billy, as she told me,
had a mind for science. But he was one of those kids
who was a below average reader. And she was hoping this
might reach him now while he’s still learning to read. Now, I have to say,
that actually made me nervous. Because as I said,
the technology was pretty basic. And I didn’t want to disappoint her. So, you can imagine how pleasantly surprised I was
about halfway through the study, the teacher reaches out to say,
“Hey, guess what?” Not only has Billy taken to the technology but I’m starting to see
improvement in his performance. So, that was nice. But nothing, nothing prepared me for what I saw when I went back to that classroom
at the end of the study. Billy had become the de facto
smartest kid in the class. No kidding. And everybody knew it. In fact, the first thing that I saw
when I walked through the door was six or seven kids
huddled around Billy’s desk asking him questions about the assignment. And boy did he have answers, it turns out. The thing is, all we really gave Billy
and his classmates was the learning equivalent
of adjustable seats. And in return, we got a glimpse of Billy’s talent. And sure, you might say, “Well, look,
that’s one kid in one classroom,” but then again, that’s one kid in one classroom. And isn’t that what it’s actually about? Nurturing individual potential. Jonas Salk was one individual
and he cured polio. What if Billy is the next Jonas Salk? What if the cure for cancer
is in his mind? Who knows? But I do know that we came
dangerously close to losing his talent before he even left grade school. Not because he didn’t understand science, but because he was still learning to read. And that’s what I mean when I say that simple solutions
can have a profound impact on individuals. So, the real question to me is how do we get these
adjustable seats for learning in the hands of every student
as fast as possible without spending more money? Here, I actually think the Air Force
has given us the formula for success. What if we ban the average in education? We know it destroys talent. Instead, what if we demanded
that the companies that sell these materials
into our classrooms design them not to the average
of dimensions of learning but to the edges? It would be a bold move. It would certainly send
a strong signal to the market: the game’s changed. But trust me, if we do this, not only will we increase the performance
of the kids in our classrooms today, we will dramatically
expand our talent pool. Because right now there are so many students
we simply cannot reach because we design on average. Design to the edges
and we will reach them, and we’ll get their talent. And I have to say I know, because I was one of those students. So today, I’m a faculty member at Harvard. But I’m also a high school dropout. It gets better. I was a high school
dropout with a 0.9 GPA. (Laughter) For those of you who don’t know,
that’s pretty bad. (Laughter) But here’s the thing. I’ve been to the very bottom
of our educational system and I’ve been to the very top. I’m here to tell you we are wasting so much talent
at every single level. And the thing is, because for every one person like me there are millions who worked as hard,
who had the ability, but who were unable to overcome the drag of an educational environment
designed on average. And their talent is forever lost to us. The thing is we can’t really afford to lose them. The good news is we don’t have to anymore. I’m telling you we have
a once in a lifetime chance, right now, to fundamentally re-imagine
the very foundation of our institutions of opportunity like education, in ways that nurture the potential
of every single individual; therefore, expand our talent pool, make us far more competitive in the world. We can do this. We know the formula. And it’s time we demand it. Thank you. (Applause)

    I was told i would not pass grade 5 and my parent had to hear from the teacher at the time that i would be a drop out. I struggled with changing schools in secondaries( High school) and barely made it out. I am now a Nurse with 2 specialties, being told I am the best Nurse to learn from and I am also an Instructor at a top university in Canada. Medicine and Nursing is my passion. I always loved studying biology but couldn't do it. The school i was in at the time had other subjects I had to pick by default (combination) with it and I was not good in them. I dropped and had to do math, physics and design where i was a below average student. After high school, I was able to rebuild and joined a Nursing school where I struggled at the beginning but started to excel and finished my studies as one of top performers.

    Very inspirational!!! Thank you for your revolution! I whole-heartedly want to support your journey to desgin to edges rather than design on average!

    'Average' made me feel that I am always insufficient because as Dr Rose says, all people have strengths and weaknesses, but the fact that I am 'below average' in certain capacities made me always hate myself.

    So relieving and happy to hear this talk. It makes me understand that I am normal and that I could be flexible and creative in approaching education etc
