Beyond Average

By Lory Hough, on August 24, 2015 11:30 PM
Lecturer Todd Rose, Ed.M.’01, Ed.D.’07, wants you to understand that when it comes to people, including students, we have to stop believing that there is such a thing as average.

ED-AverageTodd Rose isn’t your average Harvard professor — but not because he dropped out of high school, spent time on welfare, and had 10 different minimum wage jobs and a wife and kid before he even finished being a teenager.

Todd Rose isn’t your average Harvard professor because when it comes to people, the average is a statistical myth, he argues. There is no average. Repeat: There is no average. No average professor. No average worker. No average soldier. No average Joe.

And what might just be the single most important lesson for educators: There definitely is no average student. Not one. Yet, as Rose, Ed.M.’01, Ed.D.’07, a lecturer at the Ed School and director of the Mind, Brain, and Education Program, writes in his forthcoming book, The End of Average, from the moment we’re born to the moment we die, we are measured against a mythical yardstick — the average human — and it’s hurting everyone. That’s why with this book and through his nonprofit, the Center for Individual Opportunity, Rose is on a mission to dismantle this myth of the average and instead help the public understand the importance of the individual.

“We talk so much about the individual, ” he says, “but there’s such a divide between what we say we believe and what we actually do.”

HOW DID WE GET HERE?
When it comes to school systems, Rose says it’s no accident how we got here: Schools were designed during the industrial age by people who were “absolutely obsessed” with averages because averages worked so well in managing factories. The goal wasn’t to nurture creativity and develop individuality. The system mostly accomplished what it set out to do: prepare students for standardized jobs in an industrial economy. Since then, we have continued to think that the average — a human invention — represents everyone or that any deviation from the average is what defines you. You’re gifted, and you don’t need as much help, for example.

During the 1950s, the United States Air Force began thinking a lot about averages. At the time, pilots were having trouble controlling their planes. As Rose explains, at first the problem was pinned on pilot error and poor training. But the real problem turned out to be the cockpit or, more specifically, the fact that the cockpit had just one design: one for the average pilot of an earlier era, the 1920s.

The Air Force concluded that Americans had gotten bigger over the past couple of decades and they simply needed to update their measurement of the average pilot. With the help of a young Harvard College graduate named Lieutenant Gilbert Daniels, they measured more than 4,000 pilots on 10 dimensions of size that seemed important for fitting into a cockpit — torso length and chest circumference, for example. The thinking was that once they redesigned the cockpit for the average pilot of the 1950s, controlling the plane would no longer be so troublesome. Most pilots, they assumed, would be within the average range on the majority of dimensions and that a good number would even be average on all 10 dimensions.

“Do you know how many really were?” Rose says. “Zero.”

Even when just three dimensions of size were picked, fewer than 3.5 percent of the pilots fell within the range defined by Daniels as average. Instead, what Daniels found is that every single pilot had what Rose calls a jagged profile. One pilot with long arms may also have long legs while another may not. Not everyone who was average height (5 feet 9 inches) had the same chest circumference or head size.

Finally, the Air Force had its “aha” moment: If every pilot had a jagged profile and the cockpit was designed for the average pilot, it was actually designed for no one. Its response was bold — it banned the average and forced reluctant manufacturers to instead design “to the edges, ” meaning a cockpit that would be adjustable for even the extremes — the tallest or the shortest, for those with wide or narrow chests. Manufacturers balked, but once they realized the Air Force wasn’t budging, they figured it out, creating options like adjustable seats.

WHAT DOES THIS HAVE TO DO WITH EDUCATION?
Rose’s “aha” moment came when he was a doctoral student at the Ed School. Based on his own struggles in school, he came to Harvard interested in understanding individuals. But, he says, “like everyone else in psychology and neuroscience, I had been trained to use group-level statistics as an undergraduate to study people.” When he was a teaching fellow for Professor Judy Singer’s statistics class, he remembers having a conversation with her about individuality. She told him that the statistics they were using were not meant to make claims about individuals, but rather about the population at large. Rose started seeing what she meant when he was doing his own research on kids who were struggling to read.

“There would be what the research says these kids should be like, ” Rose says, “and then the reality of their individuality that hits you in the face if you spend even a few minutes with them.”

Rose approached his mentor, Professor Kurt Fischer, one of the leading pioneers in the science of the individual and the brain, to talk about this dilemma — the reality of individual kids and what the research says — and why we think this way.

“Rather than giving me a generic answer about people being too messy or complex, he just said that the root of the problem is our belief in averages — that somehow averages will tell us what we need to know about individuals, ” Rose says. “He really pushed me to accept that understanding individuals means really explaining individuality and variability rather than ignoring it or explaining it away.”

In the context of schools, Rose says that while most of us will never need to worry about the flexibility of a fighter plane, we do need to worry about what he calls “the cockpits of our economy” — classrooms. We’re spending more on education and getting not-so-great results, but instead of looking at design and fit the way the Air Force did, we blame bad teachers. We blame lazy students. We even blame parents.

“But how much of this problem is just bad design?” Rose says. Students are grouped in grades based on chronological age. Curriculum and textbooks are written to be “age appropriate.” Most standardized assessments, like the SAT or IQ test, are designed based on a comparison to a hypothetical average student. Walk into an elementary school classroom and even the literal design of the room is for the “average” kid: one size desk, one size chair, one size table.

But just as there isn’t one size pilot, there isn’t one size student or one way to learn. “Human beings don’t line up perfectly. There is no average learner, ” Rose says. Every student has a jagged learning profile, too.

“They have strengths and weaknesses. They all do, ” Rose says. “Even geniuses do.”

The danger in not understanding and appreciating this, Rose says, is that we will continue not reaching all students. Fischer once told Rose that today’s schools basically fail about 80 percent of students. A student who struggles to read may be talented in physics, but that talent gets lost because math requires reading textbooks and worksheets. A gifted student may get bored and only do the minimal amount of work, which was designed for the average student. As a result, some students fall behind or act out. Others get ignored or eventually drop out. As Rose pointed out in a TedX talk on the topic, of the 1.2 million high-schoolers in the United States who drop out every year, about 4 percent, or 50,000, are known to be gifted. And even if a student “gets through, ” Rose says, he or she may never reach full potential.

Thinking back on his own education, Rose says that poor working memory was something he struggled with and teachers didn’t recognize. As he wrote in his first book, Square Peg, “By not understanding how much people vary in their working memory, teachers force kids constantly to jump through needless hoops, much as if they were obliging their students to ride unicycles between classes. Were that the case, a kid who was a budding genius at math but hopelessly uncoordinated might never be able to get to his class and show what he could do.”

Unfortunately, Rose says, “if we ignore jaggedness, we end up treating people in one-dimensional terms” — the struggling student, the good tester. “If we want to know your intelligence, for example, we give you an IQ test that is supposed to tap a range of abilities, but then we merge that into a single score.” Imagine two young students have the same IQ score of 110 — the exact same number. One has great spatial abilities but poor working memory, and the other has the exact opposite jaggedness. “If we just want to rank them then we could say the students are more or less the same in intelligence because they have the same aggregate scores. But if we wanted to really understand who they are as individuals enough to nurture their potential, we can’t ignore the jaggedness — it is the essential information for providing them with an optimal environment and matching them with optimal strategies for success.”

In order to do this, Rose says that rather than forcing students to fit to the environment, we need to have the environment fit each student, just as the Air Force was only successful when it stopped making pilots fit into to a one-size-fits-all cockpit. Rather than getting mad at a student with poor working memory who constantly forgets to write down homework assignments, a teacher could easily help that kid by verbalizing assignments and writing them down on the white board. Rather than making all students in a grade fill out the same worksheets, assignments could be customized.

BASED ON EXPERIENCE
This issue of “fit” is exactly what helped Rose go from being that struggling student, the “troublemaker” with a 0.9 GPA in high school, to a Harvard professor with a doctorate.

“It wasn’t that a switch just got turned on one day, ” he says. He wrote in Square Peg, “I know there was no single intervention that turned my life around. No heart-to-heart talk with a great teacher. No perfectly tailored drug that helped me sit still and concentrate.”

Instead, he adds in his new book, The End of Average, “I gradually realized that if I could just figure out how to improve the fit between my environment and myself, I might be able to turn my life around.”

Fit, he believes, is the birthright of every person.

“Right now because we believe in the myth of average, we believe that opportunity means providing equal access to standardized educational experiences, ” he says. “However, since we know that nobody is actually average, it is obvious that equal access to standardized experiences is not nearly enough to provide equal opportunity. To me, if you accept the reality of individuality, then it means that we have to rethink how we define equal opportunity in education and beyond.”

Equal opportunity, then, requires equal fit between individuals and their educational environments.

“Anything less is inherently and profoundly unequal, ” Rose says. “I believe that we should set a much higher bar for ourselves in the 21st century. If we are going to be a country that cares about equal opportunity, then we must strive to ensure that equal fit is the birthright of every single child in this country. But right now in education we do not take this idea seriously, in part because until recently we didn’t have the science or technology to do it. But we do now. So if you accept the idea of equal fit, then it means something radical for the future of education — it means we cannot accept a system based on averages; it means we cannot accept standardized curricular materials, or simplistic one-dimensional assessments, or fixed amounts of time for learning or one pathway to academic success.”

And now, he says, is the perfect time to focus on individual learning. Using the technology we have on hand, educators can easily create learning environments that are flexible. Language translation programs, for example, can help students — at any school — better sound out puzzling words as they read.

Professor Howard Gardner, one of Rose’s first professors at the Ed School, says, “Todd’s focus on what we know about the individual student and how we can mobilize pedagogical and curricular resources to meet the particular student is of fundamental importance. We are fortunate enough to live at the first time in human history [when] such individualized teaching and learning is not restricted to a tiny wealthy elite but can be distributed far more widely, if not universally.”

Rose says we have already seen how technology has helped scientists around the world understand the individual, leading to major breakthroughs in everything from cancer research to the treatment of diabetes.

“And this only happened after scientists broke through a mental barrier, ” Rose says, “after they recognized this one all-important fact: that you can’t understand individuals using group averages” because there is no average cancer, no average cell, no average genome.

So how do we, as a country entrenched in an education system that distributes standardized tests and groups students based on chronological age rather than rate of learning, break through its mental barriers and start to embrace — and demand — the science of the individual?

Well, if you’re Todd Rose, you start by turning to Hollywood. 

“People in places like Hollywood, they’re used to thinking differently or being told they’re not good enough,” Rose says. “If you want to have a public that understands this new science and this new way of thinking about individuality, then it will require more than just the dissemination of information through usual channels. Instead, you have to get these ideas to permeate the culture — to change the way that people think about themselves and the people around them. To do that, I believe that you need to engage the storytellers in Hollywood because they are in the business of creating culture and changing social norms whether people realize it or not.”

Walter Haas, a founding director at Rose’s nonprofit, specializes in digital marketing and has worked on projects for Levi Strauss and Rudy Giuliani’s presidential campaign. He says getting the message to people is a first — and critical — step.

“Once you understand the world through the lens of the science of the individual, you can’t see it in any other way, ” he says. “Our goal is to simply allow more people to have that same moment of realization. We do not have the resources, frankly, or the patience to engage in a traditional policy lobbying effort. Instead, we plan to share this science-based idea in an accessible manner to stimulate ground-level demand for institutional reform.”

It’s the same approach, Rose says, that the Harvard Alcohol Project took in the 1980s, when it teamed up with every major movie studio and television network to help launch a new term into society that resulted in demand from the public: the designated driver. With the help of Hollywood, over the course of just four years, more than 160 popular movies and shows like Cheers and L.A. Law added designated drivers into scenes and drunk driving prevention into dialogue. PSAs flooded the market. The term “designated driver” even officially appeared in Webster’s Dictionary in 1991.

“It is such a terrific example of what is possible if you combine a good idea with a clever approach to getting it to the public, ”Rose says, noting that he is starting to team up with Hollywood in the same way.

His nonprofit is also creating partnerships with non-Hollywood groups that can also make a difference, like Teach For America, which places young teachers in high-needs schools, as well as influential companies that create tests for schools. They also plan on creating a free flexible digital textbook that will allow teachers to customize learning for each student.

Eventually, he says, “I want CEOs to say, ‘What’s our plan for this?’ I want schools to say, ‘Wow! We need to get our act together. This is the new thing.’”

The bottom line, Rose says, is that we all need to ask ourselves who we are supposed to be as a country.

“I’m incredibly grateful, even though it wasn’t easy, that I got a second chance, ” he says. “We need all of the potential we can possibly get. We need innovation and creativity. That’s where all of the jobs are. I keep thinking, this letting go of the average and instead focusing on the individual is just in our best interest.”
