For Your Consideration: Space Mining, Humblebraggarts, Distance Iris Scanning, American Story in Maps

1. The US House of Representatives pass a bill on Space Mining

For as long as we’ve existed, humans have looked up at the stars — and wondered. What is up there? Who is out there?

Now, to that list of questions we can add: And CAN I HAVE IT?

The United States has already shown its penchant for claiming ownership of space-based things. There are not one, not two, but six U.S. flags on the moon, in case any of you other nations start getting ideas. (Never mind that the flags have all faded to a stateless white by now.)

So it only makes sense that American lawmakers would seek to guarantee property rights for U.S. space corporations. Under the SPACE Act, which just passed the House, businesses that do asteroid mining will be able to keep whatever they dig up:

“Any asteroid resources obtained in outer space are the property of the entity that obtained such resources, which shall be entitled to all property rights thereto, consistent with applicable provisions of Federal law.”

This is how we know commercial space exploration is serious. The opportunity here is so vast that businesses are demanding federal protections for huge, floating objects they haven’t even surveyed yet.

But it’s actually important that we’re talking about this now, because we don’t want to wind up in a situation where multiple companies are fighting for the same patch of rock without having a way to resolve it. There are two key questions at stake: Who should regulate commercial space activity? And what rules should apply?

2. To Brag or To Humblebrag, that is the question
Also, best to try and not be a jackass.

Humblebragging allows people to highlight positive aspects of their lives while attempting to appear modest by masking the “good news” as a complaint. On social media, people Tweet or update their Facebook statuses with their achievements and good fortune in the guise of complaints to gain validation in the form of “likes,” comments, and so on.

But humblebragging isn’t confined to social media. Consider one of the most common job interview questions, “What’s your greatest weakness?” Think about the last time you asked this question or had to answer it. I bet that, depending on your role, you either heard or crafted an artful response that reframed a flaw as something positive: “I’m such a perfectionist that I drive myself crazy” or “I tend to work too hard, which can take a toll on my personal life.”

Whether on social media, in interviews, or in any other type of social or professional interaction, people humblebrag to try to make a positive impression on others without appearing vain. But, as it turns out, humblebragging frequently fails. Research I conducted in collaboration with my Harvard Business School colleagues Ovul Sezer and Mike Norton shows that observers find the strategy insincere. As a result, humblebraggers are rated less likeable than those who straightforwardly brag — or even those who simply complain.

These findings suggest that in job interviews, showing we are self-aware and working on improving our performance may be a more effective strategy than humblebragging. After all, authentic people who are willing to show vulnerability are likely to be the type of candidates interviewers most want to hire.

Even outside of interview contexts, humblebragging does not seem to produce the positive impressions we all hope to deliver when we use this self-promotion strategy. In follow-up studies we found that people dislike humblebraggers more than braggers and even more than complainers. And the costs of humblebragging extend beyond interpersonal evaluations to affect behavior, causing people to penalize humblebraggers financially and be less likely to help them out.

What these results seem to suggest is that when deciding whether to (honestly) brag or (deceptively) humblebrag, would-be self-promoters should choose the former — and at least reap the rewards of seeming sincere.

3. Long Range Iris Scanning Is Here.
What could possibly go wrong…

As with fingerprints, an individual’s iris is so distinctive as to be unique.

“Fingerprints, they require you to touch something. Iris, we can capture it at a distance, so we’re making the whole user experience much less intrusive, much more comfortable,” Savvides told me. Unlike other scanners, which required someone to step up to a machine, his scanner can capture someone’s iris and face as they walk by.

“There’s no X-marks-the-spot. There’s no place you have to stand. Anywhere between six and 12 meters, it will find you, it will zoom in and capture both irises and full face,” he said.

Carnegie Mellon describes a whole host of functions for the scanner beyond just police use. It could replace government IDs at the airport and elsewhere. Like other types of biometrics, it could replace a laptop’s login system.

As a sector, biometrics are undoubtedly important. Many security experts believe that passwords—and the security regime that accompanies them—are fundamentally broken. Savvides, for his part, sees biometrics as one more method of human-computer interaction.

Yet there’s something threatening about long-range iris scanning. Identification to a degree comparable to finger prints, at a distance, is not something our social habits and political institutions are wired for.

4. 70 Maps That Explain America
A geographical and cultural history lesson told through maps.

The United States of America is many things. It is the world’s most powerful country, and one of the largest. It has a history of political revolution and social progress, as well as a legacy of slavery and genocide. In one sense, mapping the United States should be a simple matter of displaying borders and geography. But America is a complex nation with a long and fascinating history that could never be captured in a single frame. Here’s a glance at America’s past and present, in 70 maps.

For Your Consideration: Predatory Education, Truck Driver as Endangered Species, AI Primer, Windfarm as Nocebo

And you thought the debate over entitlements is rough today… Over the next decade we will be having, what I’m sure will be an incredibly contentious, national conversation about basic income.

1. Preying on the Promise of Higher Education

There’s a promise we make to the next generation: Graduate from college and you can get ahead. Indeed, recent studies show that college graduates earn $1 million more than high school graduates over their lifetimes.

Yet, as we make this promise, public higher education institutions nationwide are facing a troubling trend of disinvestment. Even with poorly treated adjuncts and other nontenure-track contingent faculty doing the lion’s share of teaching at many colleges, tuition costs keep rising. Even with current federal and state student loans and grants, students have been saddled with crippling debt.

And then there’s another side of higher education. For-profit colleges are defined by putting profit before the public good, earnings over education, shareholders above students. At these schools — such as Corinthian Colleges Inc., which filed for bankruptcy this month, and ITT Tech, which is being investigated by the Securities and Exchange Commission for alleged fraud — students are products, faculty are afraid to tell accreditors the truth about where they work, and taxpayers foot the bill for aggressive marketing that preys on first-generation college students, veterans and students of color.

Funded largely by taxpayers, for-profit colleges get close to 90 percent of their funding from federal aid — that’s more than $30 billion annually. The industry feeds off our noble national goal to ensure higher education is a ladder of opportunity for all who want to climb. However, instead of offering an affordable path to a better tomorrow, they leave students with an uncertain future. Seventy-two percent of these for-profit schools produce graduates who earn less, on average, than high school dropouts.

Currently, for-profit schools enroll just 9 percent of all postsecondary students but account for nearly half of all student loan defaults. They allocate about 23 percent of their revenue to recruiting and marketing and just 17 percent to academic instruction. Compare that with institutions where academics are the priority, such as community colleges, which spend 80 percent or more on instruction.

2. Truck Driver as Endangered Species

Late last year, I took a road trip with my partner from our home in New Orleans, Louisiana to Orlando, Florida and as we drove by town after town, we got to talking about the potential effects self-driving vehicle technology would have not only on truckers themselves, but on all the local economies dependent on trucker salaries. Once one starts wondering about this kind of one-two punch to America’s gut, one sees the prospects aren’t pretty.

We are facing the decimation of entire small town economies, a disruption the likes of which we haven’t seen since the construction of the interstate highway system itself bypassed entire towns. If you think this may be a bit of hyperbole… let me back up a bit and start with this:

Source: NPR

This is a map of the most common job in each US state in 2014.

It should be clear at a glance just how dependent the American economy is on truck drivers. According to the American Trucker Association, there are 3.5 million professional truck drivers in the US, and an additional 5.2 million people employed within the truck-driving industry who don’t drive the trucks. That’s 8.7 million trucking-related jobs.

We can’t stop there though, because the incomes received by these 8.2 million people create the jobs of others. Those 3.5 million truck drivers driving all over the country stop regularly to eat, drink, rest, and sleep. Entire businesses have been built around serving their wants and needs. Think restaurants and motels as just two examples. So now we’re talking about millions more whose employment depends on the employment of truck drivers. But we still can’t even stop there.

Those working in these restaurants and motels along truck-driving routes are also consumers within their own local economies. Think about what a server spends her paycheck and tips on in her own community, and what a motel maid spends from her earnings into the same community. That spending creates other paychecks in turn. So now we’re not only talking about millions more who depend on those who depend on truck drivers, but we’re also talking about entire small town communities full of people who depend on all of the above in more rural areas. With any amount of reduced consumer spending, these local economies will shrink.

3. Rise of the Machines: A primer on Artificial Intelligence

In a speech in October at the Massachusetts Institute of Technology, Mr Musk described artificial intelligence (AI) as “summoning the demon”, and the creation of a rival to human intelligence as probably the biggest threat facing the world. He is not alone. Nick Bostrom, a philosopher at the University of Oxford who helped develop the notion of “existential risks”—those that threaten humanity in general—counts advanced artificial intelligence as one such, alongside giant asteroid strikes and all-out nuclear war. Lord Rees, who used to run the Royal Society, Britain’s foremost scientific body, has since founded the Centre for the Study of Existential Risk, in Cambridge, which takes the risks posed by AI just as seriously.

Computers can now do some narrowly defined tasks which only human brains could manage in the past (the original “computers”, after all, were humans, usually women, employed to do the sort of tricky arithmetic that the digital sort find trivially easy). An image classifier may be spookily accurate, but it has no goals, no motivations, and is no more conscious of its own existence than is a spreadsheet or a climate model. Nor, if you were trying to recreate a brain’s workings, would you necessarily start by doing the things AI does at the moment in the way that it now does them. AI uses a lot of brute force to get intelligent-seeming responses from systems that, though bigger and more powerful now than before, are no more like minds than they ever were. It does not seek to build systems that resemble biological minds. As Edsger Dijkstra, another pioneer of AI, once remarked, asking whether a computer can think is a bit like asking “whether submarines can swim”.

The worry that AI could do to white-collar jobs what steam power did to blue-collar ones during the Industrial Revolution is therefore worth taking seriously. Examples, such as Narrative Science’s digital financial journalist and Kensho’s quant, abound. Kensho’s system is designed to interpret natural-language search queries such as, “What happens to car firms’ share prices if oil drops by $5 a barrel?” It will then scour financial reports, company filings, historical market data and the like, and return replies, also in natural language, in seconds. The firm plans to offer the software to big banks and sophisticated traders. Yseop, a French firm, uses its natural-language software to interpret queries, chug through data looking for answers, and then write them up in English, Spanish, French or German at 3,000 pages a second. Firms such as L’Oréal and VetOnline.com already use it for customer support on their websites.

Technology, though, gives as well as taking away. Automated, cheap translation is surely useful. Having an untiring, lightning-fast computer checking medical images would be as well. Perhaps the best way to think about AI is to see it as simply the latest in a long line of cognitive enhancements that humans have invented to augment the abilities of their brains. It is a high-tech relative of technologies like paper, which provides a portable, reliable memory, or the abacus, which aids mental arithmetic. Just as the printing press put scribes out of business, high-quality AI will cost jobs. But it will enhance the abilities of those whose jobs it does not replace, giving everyone access to mental skills possessed at present by only a few. These days, anyone with a smartphone has the equivalent of a city-full of old-style human “computers” in his pocket, all of them working for nothing more than the cost of charging the battery. In the future, they might have translators or diagnosticians at their beck and call as well.

4. Windfarms as Nocebos
Nice writeup on how expectations guide perceptions of technology.

Any new technology carries the unexpected in with it, like a bright pin on the jacket. Health researchers picked at what might be happening between the blades, the noise, the infrasound, the electromagnetic fields. What They Found May Surprise You. Plot out the complaints onto a map, and you’ll see that they don’t actually line up against where windfarms are, nor of the size of the turbines themselves. Trawl back through the peer-reviewed literature on ‘wind turbine annoyance‘ and again, see no causal relationship between people living in proximity to wind turbines, emitted noise, and physiological health effects.

What there are instead, by the barrel, are expectations. The majority of complaints in Australia took place well after the farms had been up and running for several years, but shortly after anti-wind farm groups became vocal about health concerns. Visions and sounds do not exist in a vacuum, but are given meaning by the very personal context in which they arise – what you see and what you hear depends on what you expect.

You retire. You sell your house in the city; you buy a larger one in the countryside, in England’s green and pleasant land. Rolling fields, local pubs, long shadows on cricket greens, (you are perhaps John Major). Blackbirds warbling in the trees. Peace. Quiet. And then there on the horizon, on the hill past the new home, is a bloody great wind turbine. Cold white metal, looming like a bastard over your lovely landscape. You see it when you wake in the night and open your curtains. You see it in the morning when you come downstairs and look outside. You hear it. (You think you hear it).

Windfarms are thus nocebos – inert substances that cause harmful effects arising from whatever expectations are loaded onto them and what effects they are perceived to cause. Those who complained of the windfarms were those who had heard frightening information about how the turbines would harm their health; those who don’t like wind farms; and those who simply, from their window, from the door, could see them.

“Our dilemma is that we hate change and love it at the same time; what we really want is for things to remain the same but get better.” -Sydney J. Harris

For Your Consideration: Organized Cybercrime, Art of Living, Wearable Data, Motivation vs Discipline

1. How cyber attacks became more profitable than the drug trade

Those of us responsible for information security don’t face armed combat or the literal prospect of being hanged, but today’s environment of security risks make it necessary for different and competing players to stand united against an organized, motivated enemy out to disrupt, steal or both. The need to work together to protect company data, customer information and corporate brand has never been greater. Business survival depends upon it.

Information security professionals, no matter how big the enterprise they work for, are currently overwhelmingly outgunned by cybercrime. The threat of these criminal enterprises is large and growing and if left unchecked will have a disastrous impact on our economy in the near term. McKinsey & Company estimates that cyber attacks will slow the pace of technology and business innovation over the next few years and cost the economy as much as $3 trillion annually. Data breaches have already taken a heavy toll and costs are on the rise. An IBM-sponsored survey conducted by the Ponemon Institute found that the average cost to the company of a corporate data breach is now $5.9 million. Of this, the cost of lost business from a breach averages $3.2 million. However, this average can be misleading because some of the more widely publicized breaches in recent years have cost the affected companies billions of dollars in revenue and shareholder value.

Cyber criminals run highly organized and collaborative enterprises that operate with troubling and destructive efficiency. Juniper Networks conducted a study that found that global cybercrime takes in larger profits than the illegal drug trade. “The cyber black market has evolved from a varied landscape of discrete, ad hoc individuals into a network of highly organized groups, often connected with traditional crime groups (e.g., drug cartels, mafias, terrorist cells) and nation-states,” the report said. And even when the goals of the attackers are not monetary gain, the costs can be enormous. Though not a penny of its cash was stolen, the attack on Sony last December cost the entertainment company billions of dollars through the release of data. Types of data stolen can include financial data, personal health information (PHI) and associated insurance information.

2. The Art of Living: Wisdom of Epictetus

The disciplined introspection that philosophy affords us, Lebell suggests, also helps us cultivate the uncomfortable luxury of not-knowing and discern wisdom from here information — something even more important in our data-driven age than it was in Epictetus’s time:

The wisest among us appreciate the natural limits of our knowledge and have the mettle to preserve their naiveté. They understand how little all of us really know about anything. There is no such thing as conclusive, once-and-for-all knowledge. The wise do not confuse information or data, however prodigious or cleverly deployed, with comprehensive knowledge or transcendent wisdom. They say things like “Hmmm” or “Is that so!” a lot. Once you realize how little we do know, you are not so easily duped by fast-talkers, splashy gladhanders, and demagogues. Spirited curiosity is an emblem of the flourishing life.

In a remark that calls to mind philosopher Daniel Dennett’s spectacular meditation on the art of making good mistakes, Lebell adds:

Arrogance is the banal mask for cowardice; but far more important, it is the most potent impediment to the flourishing life. Clear thinking and self-importance cannot logically coexist.

And yet:

The legitimate glow of satisfaction at accomplishing a hard-won worthy goal should not be confused with arrogance, which is characterized by self-preoccupation and lack of interest in the feelings or affairs of others.

The acquisition of wisdom, Lebell argues, is like the acquisition of any skill — we must overcome our instinctive resistance to the unfamiliar and fear of our own incompetence before it begins to get easier, then fluid, then automatic. Eventually, we stop keeping ourselves small by people-pleasing become attuned to that increasingly clear inner voice:

The first steps toward wisdom are the most strenuous, because our weak and stubborn souls dread exertion (without absolute guarantee of reward) and the unfamiliar. As you progress in your efforts, your resolve is fortified and self-improvement progressively comes easier. By and by it actually becomes difficult to work counter to your own best interest.

By the steady but patient commitment to removing unsound beliefs from our souls, we become increasingly adept at seeing through our flimsy fears, our bewilderment in love, and our lack of self control. We stop trying to look good to others. One day, we contentedly realize we’ve stopped playing to the crowd.

In one of her most potent asides, Lebell adds to this notion of playing to the crowd and comments on the trap of popular opinion:

We are only enraged at the foolish because we make idols of those things which such people take from us.

3. Quantified Self Risks and Opportunities

The explosion in extreme tracking is part of a digital revolution in health care led by the tech visionaries who created Apple, Google, Microsoft and Sun Microsystems. Using the chips, database and algorithms that powered the information revolution of the past few decades, these new billionaires now are attempting to rebuild, regenerate and reprogram the human body.

In the aggregate data being gathered by millions of personal tracking devices are patterns that may reveal what in the diet, exercise regimen and environment contributes to disease.

Could physical activity patterns be used to not only track individuals’ cardiac health but also to inform decisions about where to place a public park and improve walkability? Could trackers find cancer clusters or contaminated waterways? A pilot project in Louisville, for example, uses inhalers with special sensors to pinpoint asthma “hot spots” in the city.

“As we have more and more sophisticated wearables that can continuously measure things ranging from your physical activity to your stress levels to your emotional state, we can begin to cross-correlate and understand how each aspect of our life consciously and unconsciously impacts one another,” Vinod Khosla, a co-founder of Sun and investor in mobile health start-ups, said in an interview.

At the 2015 Consumer Electronics Show in January, new gizmos on display included a baby bottle that measures nutritional intake, a band that measures how high you jump and “smart” clothing connected to smoke detectors. Google is working on a smart contact lens that can continuously measure a person’s glucose levels in his tears. The Apple Watch has a heart-rate sensor and quantifies when you move, exercise or stand. The company also has filed a patent to upgrade its earbuds to measure blood oxygen and temperature.

In the near future, companies hope to augment those trackers with new ones that will measure from the inside out — using chips that are ingestible or float in the bloodstream.

Some physicians, academics and ethicists criticize the utility of tracking as prime evidence of the narcissism of the technological age — and one that raises serious questions about the accuracy and privacy of the health data collected, who owns it and how it should be used. There are also worries about the implications of the proliferation of devices for broader surveillance by the government, such as what happened with cellphone providers and the National Security Agency.

4. Screw motivation, what you need is discipline

Because real life in the real world occasionally requires people do things that nobody in their right mind can be massively enthusiastic about, “motivation” runs into the insurmountable obstacle of trying to elicit enthusiasm for things that objectively do not merit it. The only solution besides slackery, then, is to put people out of their right minds. That’s a horrible, and fortunately fallacious, dilemma.

Trying to drum up enthusiasm for fundamentally dull and soul crushing activities is literally a form of deliberate psychological self-harm, a voluntary insanity: “I AM SO PASSIONATE ABOUT THESE SPREADSHEETS, I CAN’T WAIT TO FILL OUT THE EQUATION FOR FUTURE VALUE OF ANNUITY, I LOVE MY JOB SOOO MUCH!”

I do not consider self-inflicted episodes of hypomania the optimal driver of human activity. A thymic compensation via depressive episodes is inevitable, since the human brain will not tolerate abuse indefinitely. There are stops and safety valves. There are hormonal hangovers.

The worst thing that can happen is succeeding at the wrong thing – temporarily. A far superior scenario is retaining sanity, which unfortunately tends to be misinterpreted as moral failure: “I still don’t love my pointless paper-shuffling job, I must be doing something wrong.” “I still prefer cake to brocolli and can’t lose weight, maybe I’m just weak”. “I should buy another book about motivation”. Bullshit. The critical error is even approaching those issus in terms of motivation or lack thereof. The answer is discipline, not motivation.

It had long since come to my attention that people of accomplishment rarely sat back and let things happen to them. They went out and happened to things.
– Leonardo da Vinci

For Your Consideration: VR Repeat of the 90’s, Carbon-Fiber Spider-Silk, Photoshop Beauty, Sir Ken on Education Reform

The goal is twice weekly. However, life often conspires against my ability to read and distill enough information to crank out this newsletter. I will pick up and carry on as life allows and I hope you’ll still take a look when it shows up, however infrequently.

1. The VR resurgence is making the same mistakes it did in the 1990’s
Personally I’m way more interested in the near-term applications for augmented reality than I am for immersive virtual reality. I’ve been a VR booster since the 90’s when REND 386 and a Nintendo Power Glove were the pinnacle of DIY virtual reality.

Don’t let VR go wrong again!” is a blog post you should read right now, because it’s by Jacquelyn “Jacki” Morie, a VR pioneer who sees the same mistakes being made by Oculus Rift and other leaders of the VR industry that caused the technology to hit a trough of disillusionment in the early 90s. Part of the problem is a resurgence of breathless headlines like “Could Oculus Rift bring people back from the dead?” (yes, really) which inevitably lead to disaster:

“What sensational headlines like these do is create extremely unreasonable expectations for VR – the same thing that happened towards the end of the 1990s in VR’s first popularization,” she writes. “When those promises don’t pan out, then people are disappointed and things start to falter.”

Another part of the problem is a generation gap, because many of today’s VR industry leaders were barely around for VR’s first wave. (Oculus Rift founder Palmer Luckey was born in 1992.)

“That’s a big part of it,” Jacki tells me, “but the other part is people with a long history in film and related media who want to take what they know and ride the VR wave. That is why we have Cinematic VR – which is not really interactive, immersive VR as VR can really be experienced.”

Another problem is that the tech press is focused too much on covering venture funding of VR, as opposed to VR innovators: “I’d like to see more people really pushing the envelope on what VR could be. And I’d like the press to follow those people and their work, rather than just reporting on who got the latest big round of VC financing. VCs are not really investing in the full potential of VR – but on what today’s media consumers know and feel comfortable with – just put into a sexy HMD. I don’t have high hopes for the press doing that though.”

2. Feed Spiders Carbon Nanotubes and Graphene to get super-silk
And what if we feed the same to Silkworms? No more dry-clean only?

Spider silk is one of the more extraordinary materials known to science. The protein fiber, spun by spiders to make webs, is stronger than almost anything that humans can make.

The dragline silk spiders use to make a web’s outer rim and spokes is amazing stuff. It matches high-grade alloy steel for tensile strength but is about a sixth as dense. It is also highly ductile, sometimes capable of stretching to five times its length.

This combination of strength and ductility makes spider silk extremely tough, matching the toughness of state-of-the-art carbon fibers such as Kevlar.

So it goes without saying that the ability to make spider silk even stronger and tougher would be a significant scientific coup. Which is why the work of Emiliano Lepore at the University of Trento in Italy and a few pals is something of a jaw-dropper.

These guys have found a way to incorporate carbon nanotubes and graphene into spider silk and increase its strength and toughness beyond anything that has been possible before. The resulting material has properties such as fracture strength, Young’s modulus, and toughness modulus higher than anything ever measured.

The team’s approach is relatively straightforward. They started with 15 Pholcidae spiders, collected from the Italian countryside, which they kept in controlled conditions in their lab. They collected samples of dragline silk produced by these spiders as a reference.

The team then used a neat trick to introduce carbon nanotubes and graphene flakes into the spider silk. They simply sprayed the spiders with water containing the nanotubes or flakes and then measured the mechanical properties of the silk that the spiders produced.

For each strand of silk, they fixed the fiber between two C-shaped cardboard holders and placed it in a device that can measure the load on a fiber with a resolution of 15 nano-newtons and any fiber displacement with a resolution of 0.1 nanometers.

The results make for impressive reading. “We measure a fracture strength up to 5.4 GPa, a Young’s modulus up to 47.8 GPa and a toughness modulus up to 2.1 GPa,” say Lepore and co. “This is the highest toughness modulus for a fibre, surpassing synthetic polymeric high performance fibres (e.g. Kelvar49) and even the current toughest knotted fibers,” they say.

In other words, giving spiders water that is infused with carbon nanotubes makes them weave silk stronger than any known fiber.

3. Time-Lapse View of Creating Impossible Beauty Standards

Photoshop celebrated its 25th anniversary recently with a video showing off its positive contributions to the world, such as hobbit-effects. The reason we need to be reminded of the technology’s airbrushing benefits is because Photoshop is also frequently used to create impossible standards of beauty—specifically in women. A new series of video has just showed up online to provide an in-depth look at what goes ion in the upper echelon of imperfection-elimination.

Elizabeth Moss (nope, not that Elisabeth Moss) is a professional retouch wizard who has worked with magazines like Vogue and Vanity Fair, and she recently created a behind-the-scenes video showing off what goes into the craft at her level. Over the course of three time-lapse videos, made with her studio RARE Digital Art, Moss distills hours and hours of meticulous detail work down to a matter of minutes. Some of the differences are subtler than what we’ve seen before.


4. Sir Ken Robinson on Education Reform

Q: What kind of education are you talking about?

A: It’s to make education more personalized for students and more customized to the communities in which they are part of. The reason I say that is that education has become, over the past 20 years particularly, increasingly seen as kind of a strategic issue for governments. Years ago, countries didn’t pay much attention to what was happening in other countries in terms of education. People in France weren’t much interested in what was happening in Germany and Italy …. Nowadays people compare the systems like they are defense policies or economic policies, and it is because people all around the world recognize that education is absolutely fundamental to economic growth. In fact, it is fundamental to the social fabric, fundamental to cultural development and so on. And the interest in all of these things has been driven very hard by the publication of these league tables by the OECD [Organization for Economic Cooperation and Development] and PISA [the international test]. You now, seriously, have secretaries of state in America wringing their hands that we are 17th or 18th or 20th, whatever it is this time around [on PISA] in science and math and so on. Education has become a big strategic issue.

Secondly, therefore, governments at the state and federal level have taken the reins of education in a very significant sort of way. It began in this country with the report in the Reagan administration, “A Nation at Risk,” when there was this massive concern that, as they put it, schools in this country were “drowning in a rising tide of mediocrity.” No Child Left Behind was part of that, too. So everyone knows education is important and governments have got deeply involved in trying to fix it. My argument is that it is important to fix it, it is important for not only economic reasons and all the other reasons. But strategies the governments around the world have adopted for the most part, including this one, have been completely back to front, and have been actually entirely counterproductive.

If you look at measures that No Child Left Behind was intended to be judged by … this whole standards movement has been at best a very partial success but in other ways a catastrophic [failure]… We have got and have had appalling high levels of non-graduation, terrible rates of turnovers and resignations  among teachers and principals, and a profession that has been in many ways demoralized by the whole process. … And what lies behind that is the standards movement. It’s well intentioned to raise standards, but the mistake it makes is that it fails to recognize that education is not a mechanical impersonal process that can improved by tweaking standards and regularly testing. … It’s a human process. It’s real people going through the system and whether the system takes into account who they are, what engages them, isn’t incidental. It is the core of what education is.

“Don’t let the fear of the time it will take to accomplish something stand in the way of your doing it. The time will pass anyway; we might just as well put that passing time to the best possible use.” -Earl Nightingale
