Hans Rosling: Asia's rise -- how and when/talks/hans_rosling_asia_s_rise_how_and_when.htmlAbout this talkHans Rosling was a young guest student in India when he first realized that Asia had all the capacities to reclaim its place as the world's dominant economic force. At TED India, he graphs global economic growth since 1858 and predicts the exact date that India and China will outstrip the US.About Hans RoslingAs a doctor and researcher, Hans Rosling identified a new paralytic disease induced by hunger in rural Africa.TranscriptOnce upon a time, at the age of 24, I was a student at St. John's Medical College in Bangalore. I was a guest student during one month of a public health course. And that changed my mindset forever. The course was good, but it was not the course content in itself that changed the mindset. It was the brutal realization, the first morning, that the Indian students were better than me.(Laughter)You see, I was a study nerd. I loved statistics from a young age. And I studied very much in Sweden. I used to be in the upper quarter of all courses I attended. But in St. John's, I was in the lower quarter. And the fact was that Indian students studied harder than we did in Sweden. They read the textbook twice, or three times or four times. In Sweden we read it once and then we went partying.(Laugher)And that, to me, that personal experience was the first time in my life that the mindset I grew up with was changed. And I realized that perhaps the Western world will not continue to dominate the world forever. And I think many of you have the same sort of personal experience. It's that realization of someone you meet that really made you change your ideas about the world. It's not the statistics, although I tried to make it funny. And I will now, here, onstage, try to predict when that will happen -- that Asia will regain its dominant position as the leading part of the world, asit used to be, over thousands of years. And I will do that by trying to predict precisely at what year the average income per person in India, in China, will reach that of the West. And I don't mean the whole economy, because to grow an economy of India to the size of U.K. -- that's a piece of cake, with one billion people. But I want to see when will the average pay, the money for each person, per month, in India and China, when will that have reached that of U.K. and the United States?But I will start with a historical background. And you can see my map if I get it up here. No? I would start at 1858. 1858 was a year of great technological advancement in the West. That was the year when Queen Victoria was able, for the first time, to communicate with President Buchanan, through the Transatlantic Telegraphic Cable. And they were the first to "Twitter" transatlantically. (Laughter) (Applause) And I've been able, through this wonderful Google and Internet, to find the text of the telegram sent back from President Buchanan to Queen Victoria. And it ends like this: "This telegraph is a fantastic instrument to diffuse religion, civilization, liberty and law throughout the world."Those are nice words. But I got sort of curious of what he meant with liberty, and liberty for whom. And we will think about that when we look at the wider picture of the world in 1858. Because 1858 was also watershed year in the history of Asia. 1858 was the year when the courageous uprising against the foreign occupation of India was defeated by the British forces. And India was up to 89 years more of foreign domination.1858 in China was the victory in the Opium War by the British forces. And that meant that foreigners, as it said in the treaty, were allowed to trade freely in China. It meant paying with opium for Chinese goods.In 1858 in Japan, was the year when Japan had to sign the Harris Treaty and accept trade on favorable condition for the U.S. And they were threatened by those black ships there, that had been in Tokyo harbor over the last year. But, Japan, in contrast to India and China maintained its national sovereignty.On this axis, as I used to have income per person in comparable dollar. And on that axis I have life expectancy, the health of people. And I also bring an innovation here. I have transformed the laser beam into anecological, recyclable version here, in green India.(Applause)And we will see, you know. Look here, 1858, India was here, China was here, Japan was there, United States and United Kingdom was richer over there. And I will start the world like this. India was not always like this level. Actually if we go back into the historical record, there was a time hundreds of years ago when the income per person in India and China was even above that of Europe. But 1850 had already been many many years of foreign domination, and India had been deindustralized. And you can see that the countries who were growing their economy was United States and United Kingdom. And they were also, by the end of the century, getting healthy, and Japan was starting to catch up. India was trying down here. Can you see how it starts to move there? But really, really natural sovereignty was good for Japan. And Japan is trying to move up there. And it's the new century now. Health is getting better, United Kingdom, United States. But careful now -- we are approaching the First World War. And the First World War, you know, we'll see a lot of deaths and economical problems here. United Kingdom is going down. And now comes the Spanish flu also. And then after the First World War, they continue up. Still under foreign domination, and without sovereignty, India and China are down in the corner. Not much has happened. They have grown their population but not much more. In the 1930's now, you can see that Japan is going to a period of war, with lower life expectancy. And the Second World War was a really terrible event, also economically for Japan. But they did recover quite fast afterwards. And we are moving into the new world. In 1947 India finally gained its independence. And they could raise the Indian flag and become a sovereign nation, but in very big difficulties down there.(Applause)In 1949 we saw the emergence of the modern China in a way which surprised the world. And what happened? What happens in the after independence? You can see that the health started to improve. Children started to go to school. Health services were provided. This is the Great Leap Forward, when China fell down. It was central planning by Mao Tse Tung. China recovered. Then they said, "Nevermore, stupid central planning." But they went up here, and India was trying to follow. And they were catching up indeed. And both countries had the better health, but still a very low economy.And we came to 1978, and Mao Tse Tung died, and a new guy turned up from the left. And it was Deng Xiaoping coming out here. And he said, "Doesn't matter if a cat is white or black, as long as it catches mice." Because catching mice is what the two cats wanted to do. And you can see the two cats being here, China and India, wanting to catch the mices over there, you know. And they decided to go not only for health and education, but also starting to grow their economy. And the market reformer was successful there. In '92 India follows with a market reform. And they go quite closely together, and you can see that the similarity with India and China, in many ways, are greater than the differences with them.And here they march on. And will they catch up?This is the big question today. There they are today.Now what does it mean that the -- (Applause) the averages there -- this is the average of China. If I would split China, look here, Shanghai has already catched up. Shanghai is already there. And it's healthier than the United States. But on the other hand, Guizhou, one of the poorest inland provinces of China, is there. And if I split Guizhou into urban and rural, the rural part of Guizhou goes down there. You see these enormous inequity in China, in the midst of fast economic growth.And if I would also look at India, you have another type of inequity, actually, in India. The geographical, macrogeographical difference is not so big. Uttar Pradesh, the biggest of the states here, is poorer and has a lower health than the rest of India. Kerala is flying on top there, matching United States in health, but not in economy. And here, Maharashtra, with Mumbai, is forging forward. Now in India, the big inequities are within the state, rather than between the states. And that is not a bad thing, in itself. If you have a lot inequity, macrogeographical inequities can be more difficult in the long term, to deal with, than if it is in the same area where you have a growth center relatively close to where poor people are living.No, there is one more inequity. Look there, United States. (Laughter) Oh, they broke my frame. Washington, D.C. went out here. My friends at Gapminder wanted me to show this because there is a new leader in Washington who is really concerned about the health system. And I can understand him, because Washington, D.C. is so rich over there but they are not as healthy as Kerala. It's quite interesting isn't it? (Applause) I cansee a business opportunity for Kerala, helping fix the health system in the United States.(Laughter)(Applause)Now here we have the whole world. You have the legend down there. And when you see the two giant cats here, pushing forward, you see that in between them and ahead of them, is the whole emerging economies of the world, which Thomas Friedman so correctly called the "flat world." You can see that in health and education a large part of the world population is putting forward, but in Africa, and other parts, as in rural Guizhou in China, there is still people with low health and very low economy. We have an enormous disparity in the world. But most of the world in the middle are pushing forwards very fast.Now, back to my projections. When will it catch up? I have to go back to very conventional graph. I will show income per person on this axis instead, poor down here, rich up there. And then time here, from 1858 I start the world. And we shall see what will happen with these countries. You see, China under foreign domination actually lowered their income and came down to the Indian level here. Whereas U.K. and United States is getting richer and richer. And after Second World War, United States is richer than U.K. But independence is coming here. Growth is starting, economic reform. Growth is faster, and with projection from IMF you can see where you expect them to be in 2014.Now, the question is, "When will the catch-up take place?" Look at, look at the United States. Can you see the bubble? The bubbles, not my bubbles, but the financial bubbles. That's the dot com bubble. This is the Lehman Brothers doorstep there. You see it came down there. And it seems this is another rock coming down there, you know. So they doesn't seem to go this way, these countries. They seem to go in a more humble growth way, you know. And people interested in growth are turning their eyes towards Asia.I can compare to Japan. This is Japan coming up. You see, Japan did it like that. We add Japan to it. And there is no doubt that fast catch up can take place. Can you see here what Japan did? Japan did it like this, until full catch-up, and then they follow with the other high-income economies. But the real projections for those ones, I would like to give it like this. Can be worse, can be better. It's always difficult to predict, especiallyabout the future. Now, a historian tells me it's even more difficult to predict about the past.(Laughter)I think I'm in a difficult position here. Inequalities in China and India I consider really the big obstacle because to bring the entire population into growth and prosperity is what will create a domestic market, what will avoid social instability, and which will make use of the entire capacity of the population. So, social investments in health, education and infrastructure, and electricity is really what is needed in India and China. You know the climate. We have great international experts within India telling us that the climate is changing, and actions has to be taken, otherwise China and India would be the countries most to suffer from climate change. And I consider India and China the best partners in the world in a good global climate policy. But they ain't going to pay for what others, who have more money, have largely created, and I can agree on that.But what I'm really worried about is war. Will the former rich countries really accept a completely changed world economy, and a shift of power away from where it has been the last 50 to 100 to 150 years, back to Asia? And will Asia be able to handle that new position of being in charge of being the most mighty, and the governors of the world? So, always avoid war, because that always pushes human beings backward. Now if these inequalities, climate and war can be avoided, get ready for a world in equity. Because this is what seems to be happening.And that vision that I got as a young student, 1972, that Indians can be much better than Swedes, is just about to happen. And it will happen precisely the year 2048 in the later part of the summer, in July, more precisely, the 27th of July. (Applause) The 27th of July, 2048 is my 100th birthday. (Laughter) And I expect to speak in the first session of the 39th TED India. Get your bookings in time. Thank you very much.。

Alan Russell:The potential of regenerative medicine0:12 I'm going to talk to you today about hopefully converting fear into hope.When we go to the physician today --when we go to the doctor's office and we walk in,there are words that we just don't want to hear.There are words that we're truly afraid of. Diabetes, cancer, Parkinson's, Alzheimer's,heart failure, lung failure --things that we know are debilitating diseases, for which there's relatively little that can be done.0:41 And what I want to lay out for you today is a different way of thinking about how to treat debilitating disease, why it's important, why without it perhaps our health care system will melt down if you think it already hasn't, and where we are clinically today, and where we might go tomorrow, and what some of the hurdles are. And we're going to do all of that in 18 minutes, I promise.1:02 I want to start with this slide, because this slide sort of tells the story the way Science Magazine thinks of it. This was an issue from 2002 that they published with a lot of different articles on the bionic human. It was basically a regenerative medicine issue. Regenerative medicine is an extraordinarily simple concept that everybody can understand. It's simply accelerating the pace at which the body heals itselfto a clinically relevant timescale. So we know how to do this in many of the ways that are up there. We know that if we have a damaged hip, you can put an artificial hip in. And this is the idea that Science Magazine used on their front cover. 1:43This is the complete antithesis of regenerative medicine. This is not regenerative medicine.Regenerative medicine is what Business Week put up when they did a story about regenerative medicine not too long ago. The idea is that instead of figuring out how to ameliorate symptoms with devices and drugs and the like -- and I'll come back to that theme a few times -- instead of doing that, we will regenerate lost function of the body by regenerating the function of organs and damaged tissue.So that at the end of the treatment, you are the same as you were at the beginning of the treatment.2:20Very few good ideas -- if you agree that this is a good idea -- very few good ideas are truly novel. And this is just the same. If you look back in history, Charles Lindbergh, who was better known for flying airplanes, was actually one of the first people along with Alexis Carrel, one of the Nobel Laureates from Rockefeller, to begin to think about, could you culture organs? And they published this book in 1937,where they actually began to think about, what could you do in bio-reactors to grow whole organs?We've come a long way since then. I'm going to share with you some of the exciting work that's going on.2:57But before doing that, what I'd like to do is share my depression about the health care system and the need for this with you. Many of the talks yesterday talked about improving the quality of life, and reducing poverty, and essentially increasing life expectancy all around the globe. One of the challenges is that the richer we are, the longer we live. And the longer we live, the more expensive it is to take care of our diseases as we get older.3:25This is simply the wealth of a country versus the percent of population over the age of 65. And you can basically see that the richer a country is, the older the people are within it. Why is this important? And why is this a particularly dramatic challenge right now? If the average age of your population is 30, then the average kind of disease that you have to treat is maybe a brokenankle every now and again,maybe a little bit of asthma. If the average age in your country is 45 to 55, now the average person is looking at diabetes, early-onset diabetes, heart failure, coronary artery disease -- things that are inherently more difficult to treat, and much more expensive to treat.4:07Just have a look at the demographics in the U.S. here. This is from "The Untied States of America." In 1930, there were 41 workers per retiree. 41 people who were basically outside of being really sick,paying for the one retiree who was experiencing debilitating disease. In 2010, two workers per retiree in the U.S. And this is matched in every industrialized, wealthy country in the world. How can you actually afford to treat patients when the reality of getting old looks like this?4:42This is age versus cost of health care. And you can see that right around age 45, 40 to 45, there's a sudden spike in the cost of health care. It's actually quite interesting. If you do the right studies, you can look at how much you as an individual spend on your own health care, plotted over your lifetime. And about seven years before you're about to die, there's a spike. And you can actually -- (Laughter) -- we won't get into that. (Laughter)5:17There are very few things, very few things that you can really do that will change the way that you can treat these kinds of diseases and experience what I would call healthy aging. I'd suggest there are four things, and none of these things include an insurance system or a legal system. All those things do is change who pays. They don't actually change what the actual cost of the treatment is.5:43One thing you can do is not treat. You can ration health care. We won't talk about that anymore. It's too depressing. You can prevent. Obviously a lot of monies should be put into prevention.5:55But perhaps most interesting, to me anyway, and most important, is the idea of diagnosing a disease much earlier on in the progression, and then treating the disease to cure the disease instead of treating a symptom. Think of it in terms of diabetes, for instance. Today, with diabetes, what do we do? We diagnose the disease eventually, once it becomes symptomatic, and then we treat the symptom for 10, 20, 30, 40 years. And we do OK. Insulin's a pretty good therapy. But eventually it stops working, and diabetes leads to a predictable onset of debilitating disease.6:34Why couldn't we just inject the pancreas with something to regenerate the pancreas early on in the disease, perhaps even before it was symptomatic? And it might be a little bit expensive at the time that we did it, but if it worked, we would truly be able to do something different.6:50This video, I think, gets across the concept that I'm talking about quite dramatically. This is a newt re-growing its limb. If a newt can do this kind of thing, why can't we? I'll actually show you some more important features about limb regeneration in a moment. But what we're talking about in regenerative medicine is doing this in every organ system of the body, for tissues and for organs themselves. So today's reality is that if we get sick, the message is we will treat your symptoms, and you need to adjust to a new way of life.7:29I would pose to you that tomorrow -- and when tomorrow is we could debate, but it's within the foreseeable future -- we will talk about regenerative rehabilitation. There's a limb prosthetic up here,similar actually one on the soldier that's come back from Iraq. There are 370 soldiers that have come back from Iraq that have lost limbs. Imagine if instead of facing that, they could actually face the regeneration of that limb. It's a wild concept. I'll show you where we are at the moment in working towards that concept.8:01But it's applicable, again, to every organ system. How can we do that? The way to do that is to develop a conversation with the body. We need to learn to speak the body's language. And to switch on processes that we knew how to do when we were a fetus. A mammalian fetus, if it loses a limb during the first trimester of pregnancy, will re-grow that limb. So our DNA has the capacity to do these kinds of wound-healing mechanisms. It's a natural process, but it is lost as we age. In a child, before the age of about six months, if they lose their fingertip in an accident, they'll re-grow their fingertip. By the time they're five, they won't be able to do that anymore.8:45So to engage in that conversation with the body, we need to speak the body's language. And there are certain tools in our toolbox that allow us to do this today. I'm going to give you an example of three of these tools through which to converse with the body.9:01The first is cellular therapies. Clearly, we heal ourselves in a natural process, using cells to do most of the work. Therefore, if we can find the right cells and implant them in the body, they may do the healing.Secondly, we can use materials. We heard yesterday about the importance of new materials. If we can invent materials, design materials, or extract materials from a natural environment, then we might be able to have those materials induce the body to heal itself. And finally, we may be able to use smart devices that will offload the work of the body and allow it to heal.9:38I'm going to show you an example of each of these, and I'm going to start with materials. Steve Badylak -- who's at the University of Pittsburgh -- about a decade ago had a remarkable idea. And that idea was that the small intestine of a pig, if you threw away all the cells, and if you did that in a way that allowed it to remain biologically active, may contain all of the necessary factors and signals that would signal the body to heal itself. And he asked a very important question. He asked the question, if I take that material, which is a natural material that usually induces healing in the small intestine, and I place it somewhere else on a person's body, would it give a tissue-specific response, or would it make small intestine if I tried to make a new ear?10:23I wouldn't be telling you this story if it weren't compelling. The picture I'm about to show you is a compelling picture. (Laughter) However, for those of you that are even the slightest bit squeamish --even though you may not like to admit it in front of your friends -- the lights are down. This is a good time to look at your feet, check your Blackberry, do anything other than look at the screen. (Laughter)10:51What I'm about to show you is a diabetic ulcer. And although -- it's good to laugh before we look at this.This is the reality of diabetes. I think a lot of times we hear about diabetics, diabetic ulcers, we just don't connect the ulcer with the eventual treatment, which is amputation, if you can't heal it. So I'm going to put the slide up now. It won't be up for long. This is a diabetic ulcer. It's tragic. The treatment for this is amputation. This is an older lady. She has cancer of the liver as well as diabetes, and has decided to die with what' s left of her body intact.11:27And this lady decided, after a year of attempted treatment of that ulcer, that she would try this new therapy that Steve invented. That's what the wound looked like 11 weeks later. That material contained only natural signals. And that material induced the body to switch back on a healing response that it didn't have before.11:48There's going to be a couple more distressing slides for those of you -- I'll let you know when you can look again. This is a horse. The horse is not in pain. If the horse was in pain, I wouldn't show you this slide. The horse just has another nostril that's developed because of ariding accident. Just a few weeks after treatment -- in this case, taking that material, turning it into a gel, and packing that area, and then repeating the treatment a few times -- and the horse heals up. And if you took an ultrasound of that area, it would look great.12:15Here's a dolphin where the fin's been re-attached. There are now 400,000 patients around the worldwho have used that material to heal their wounds. Could you regenerate a limb? DARPA just gave Steve 15 million dollars to lead an eight-institution project to begin the process of asking that question.12:34And I'll show you the 15 million dollar picture. This is a 78 year-old man who's lost the end of his fingertip. Remember that I mentioned before the children who lose their fingertips. After treatment that's what it looks like. This is happening today. This is clinically relevant today. There are materials that do this. Here are the heart patches.12:55But could you go a little further? Could you, say, instead of using material, can I take some cells along with the material, and remove a damaged piece of tissue, put a bio-degradable material on there? You can see here a little bit of heart muscle beating in a dish. This was done by Teruo Okano at Tokyo Women's Hospital. He can actually grow beating tissue in a dish. He chills the dish, it changes its properties and he peels it right out of the dish. It's the coolest stuff.13:24Now I'm going to show you cell-based regeneration. And what I'm going to show you here is stem cells being removed from the hip of a patient. Again, if you're squeamish, you don't want to watch. But this one's kind of cool. So this is a bypass operation, just like what Al Gore had, with a difference. In this case, at the end of the bypass operation, you're going to see the stem cells from the patient that were removed at the beginning of the procedure being injected directly into the heart of the patient. And I'm standing up here because at one point I'm going to show you just how early this technology is. Here go the stem cells, right into the beating heart of the patient. And if you look really carefully, it's going to be right around this point you'll actually see a back-flush. You see the cells coming back out. We need all sorts of new technology, new devices, to get the cells to the right place at the right time.14:17Just a little bit of data, a tiny bit of data. This was a randomized trial. At this time this was an N of 20. Now there's an N of about 100. Basically, if you take an extremely sick patient and you give them a bypass, they get a little bit better. If you give them stem cells as well as their bypass, for these particular patients, they became asymptomatic. These are now two years out. The coolest thing would be is if you could diagnose the disease early, and prevent the onset of the disease to a bad state.14:46This is the same procedure, but now done minimally invasively, with only three holes in the body where they're taking the heart and simply injecting stem cells through a laparoscopic procedure. There go the cells. We don't have time to go into all of those details, but basically, that works too. You can take patients who are less sick, and bring them back to an almost asymptomatic state through that kind of therapy.15:12Here's another example of stem-cell therapy that isn't quite clinical yet, but I think very soon will be.This is the work of Kacey Marra from Pittsburgh, along with a number of colleagues around the world.They've decided that liposuction fluid, which -- in the United States, we have a lot of liposuction fluid.(Laughter) It's a great source of stem cells. Stem cells are packed in that liposuction fluid. So you could go in, you could get your tummy-tuck. Out comes the liposuction fluid, and in this case, the stem cells are isolated and turned into neurons. All done in the lab. And I think fairly soon, you will see patients being treated with their own fat-derived, oradipose-derived, stem cells.15:53I talked before about the use of devices to dramatically change the way we treat disease. Here's just one example before I close up. This is equally tragic. We have a very abiding and heartbreaking partnership with our colleagues at the Institute for Surgical Research in the US Army, who have to treat the now 11,000 kids that have come back from Iraq. Many of those patients are very severely burned.16:16And if there's anything that's been learned about burn, it's that we don't know how to treat it. Everything that is done to treat burn -- basically we do a sodding approach. We make something over here, and then we transplant it onto the site of the wound, and we try and get the two to take. In this case here, a new, wearable bio-reactor has been designed -- it should be tested clinically later this year at ISR -- by Joerg Gerlach in Pittsburgh. And that bio-reactor will lay down in the wound bed. The gun that you see there sprays cells. That's going to spray cells over that area. The reactor will serve to fertilize the environment, deliver other things as well at the same time, and therefore we will seed that lawn, as opposed to try the sodding approach. It's a completely different way of doing it.17:04So my 18 minutes is up. So let me finish up with some good news, and maybe a little bit of bad news.The good news is that this is happening today. It's very powerful work. Clearly the images kind of get that across. It's incredibly difficult because it's highly inter-disciplinary. Almost every field of science engineering and clinical practice is involved in trying to get this to happen. 17:29A number of governments, and a number of regions, have recognized that this is a new way to treat disease. The Japanese government were perhaps the first, when they decided to invest first 3 billion,later another 2 billion in this field. It's no coincidence. Japan is the oldest country on earth in terms of its average age. They need this to work or their health system dies. So they're putting a lot of strategic investment focused in this area. The European Union, same thing. China, the same thing. China just launched a national tissue-engineering center. The first year budget was 250 million US dollars.18:05In the United States we've had a somewhat different approach. (Laughter) Oh, for Al Gore to come and be in the real world as president. We've had a different approach. And the approach has basically been to just sort of fund things as they come along. But there's been no strategic investment to bring all of the necessary things to bear and focus them in a careful way.18:30And I'm going to finish up with a quote, maybe a little cheap shot, at the director of the NIH, who's a very charming man. Myself and Jay Vacanti from Harvard went to visit with him and a number of his directors of his institute just a few months ago, to try and convince him that it was time to take just a little piece of that 27.5 billion dollars that he's going to get next year and focus it, in a strategic way, to make sure we can accelerate the pace at which these things get to patients. And at the end of a very testy meeting, what the NIH director said was, "Your vision is larger than our appetite." I'd like to close by saying that no one's going to change our vision, but together we can change his appetite. Thank you.。

reading(the transcript)When I was 27 years old,I left a very demanding job in management consulting for a job that was even more demanding: teaching.I went to teach seventh graders math in the New York City public schools.And like any teacher, I made quizzes and tests.I gave out homework assignments.When the work came back, I calculated grades.What struck me was that IQ was not the only difference between my best and my worst students.Some of my strongest performers did not have stratospheric IQ scores.Some of my smartest kids weren't doing so well.And that got me thinking.The kinds of things you need to learn in seventh grade math,sure, they're hard: ratios, decimals, the area of a parallelogram.But these concepts are not impossible,and I was firmly convinced that every one of my students could learn the material if they worked hard and long enough.After several more years of teaching,I came to the conclusion that what we need in education is a much better understanding of students and learning from a motivational perspective,from a psychological perspective.In education, the one thing we know how to measure best is IQ.But what if doing well in school and in life depends on much more than your ability to learn quickly and easily?So I left the classroom,and I went to graduate school to become a psychologist.I started studying kids and adults in all kinds of super challenging settings,and in every study my question was,who is successful here and why?My research team and I went to West Point Military Academy.We tried to predict which cadets would stay in military training and which would drop out.We went to the National Spelling Bee and tried to predict which children would advance farthest in competition.We studied rookie teachers working in really tough neighborhoods,asking which teachers are still going to be here in teaching by the end of the school year,and of those, who will be the most effective at improving learning outcomes for their students?We partnered with private companies, asking,which of these salespeople is going tokeep their jobs?And who's going to earn the most money?In all those very different contexts,one characteristic emerged as a significant predictor of success.And it wasn't social intelligence.It wasn't good looks, physical health,and it wasn't IQ.It was grit.Grit is passion and perseverance for very long-term goals.Grit is having stamina.Grit is sticking with your future, day in, day out,not just for the week, not just for the month,but for years,and working really hard to make that future a reality.Grit is living life like it's a marathon, not a sprint.A few years ago,I started studying grit in the Chicago public schools.I asked thousands of high school juniors to take grit questionnaires,and then waited around more than a year to see who would graduate.Turns out that grittier kids were significantly more likely to graduate,even when I matched them on every characteristic I could measure,things like family income,standardized achievement test scores,even how safe kids felt when they were at school.So it's not just at West Point or the National Spelling Bee that grit matters.It's also in school,especially for kids at risk for dropping out.To me, the most shocking thing about grit is how little we know,how little science knows, about building it.Every day, parents and teachers ask me,"How do I build grit in kids?What do I do to teach kids a solid work ethic?How do I keep them motivated for the long run?"The honest answer is,I don't know.What I do know is that talent doesn't make you gritty.Our data show very clearly that there are many talented individuals who simply do not follow through on their commitments.In fact, in our data, grit is usually unrelated or even inversely related to measures of talent.So far, the best idea I've heard about building grit in kids is something called "growth mindset."This is an idea developed at Stanford University by Carol Dweck,and it is the belief that the ability to learn is not fixed,that it can change with your effort.Dr. Dweck has shown that when kids read and learn about the brain and how it changes and grows in response to challenge,they're much more likely to persevere when they fail,because they don't believe that failure is a permanent condition.So growth mindset is a great idea for building grit.But we need more.And that's where I'm going to end my remarks,because that's where we are.That's the work that stands before us.We need to take our best ideas, our strongest intuitions,and we need to test them.We need to measure whether we've been successful,and we have to be willing to fail, to be wrong,to start over again with lessons learned.In other words, we need to be gritty about getting our kids grittier.Thank you.TED - Grit。
