Steven Pinker: “I Manage My Controversy Portfolio Carefully” | People I (Mostly) Admire | Episode 1

Key Takeaway

Build a daily “graphs, not headlines” habit: choose one issue you care about, find a credible long-term data series, and compare its trend with the latest news cycle. This counters the mind’s bias toward vivid, sudden disasters while making room for genuine risks. Then treat the gap between current conditions and desired outcomes as a problem to solve, not proof that progress is impossible.

Episode Overview

Steven Levitt talks with psychologist and linguist Steven Pinker about progress, rationality, climate policy, language, intellectual controversy, and living well. Pinker argues that reason, science, and long-run data reveal substantial human progress, while also offering practical ways to think more clearly about risk, disagreement, language learning, and gratitude.

for most of human history their whole spheres where we just don't really insist on knowing what's true or what's false we want morally uplifting dramatically compelling narratives given that our species has transformed the world and discovered the secrets of life in the universe built amazing things how do we do it despite these cognitive infirmities and how can we make ourselves smarter thank you I first met Steve Pinker 15 years ago and I had one lunch with them and it was such a fabulous conversation that I've been thinking about that lunch ever since welcome to people I mostly admire with Steve Levitt he's an amazing thinker he's a Harvard psychologist he's the kind of person who bring Insight that any subject that comes up and I'd say my favorite research is the work he's done just documenting the amazing progress that humankind has created over the last 200 years and look I know it doesn't feel like it right now we're in the middle of the covet doldrums but I think it's important that we keep in mind that we are on a positive track even though right now it's not the best time foreign such a pleasure to get to talk today with Stephen Pinker not only one of the most widely admired public intellectuals but also a path-breaking linguist and a brain scientist so I've met a lot of brilliant people but what makes you seem really special to me is that it's over here I think in brilliant people to have any Common Sense would you agree with me that common sense is one of your best attributes I'm probably not the person to judge I know from my own field of psychology that we are all apt to overestimate our talents and so if I were to say I had a lot of common sense that would probably not be an exercise of Common Sense here's what I mean by Common Sense so you've had this academic career and you do like super complicated linguistic things and yet you've come to write these incredibly readable books that are loaded with really simple statistics and sensible logic that just it's really hard to disagree with you conclusion so let's just take example your latest book is Enlightenment now the case for reason science humanism and progress could you guys give us the one minute version of that book for people who haven't read it yes it argues that we ought to deal with our problems by increasing our knowledge trying to figure out how the world Works through the use of reason and what I consider to be simply the application of reason to the physical world mainly science that we should do so with a goal of making as many people as well off as possible and that if we do that we can succeed namely progress is a fact it comes about as the result of people applying their Ingenuity to reduce human suffering and increase human flourishing supported by data suggesting that progress actually has taken place our lives are longer and healthier and richer and better educated and happier than they were in the past so I have to say well I agree with literally every sentence in that book I personally never would have written such a book because it seems so completely totally obviously true I mean any Economist in the world would tell you that that's true but clearly people don't seem to know these facts and don't seem to understand I know you've had a lot of people disagree and uh what do they even disagree with you think it is interesting that economists for all of the cliches about the Dismal profession do tend to have a more positive view because they are aware of one of the greatest facts in human history namely that Prosperity has skyrocketed since the Industrial Revolution and the data-oriented mindset leads economists like many data-oriented people to have a different view of the world than you would get from journalism and I think there's a systematic reason why and that is that journalism presents a systematically biased sample of World Experience namely by covering things that happen especially things that happen suddenly there's a built-in bias to cover things that go wrong because things can fall apart very very quickly whereas Improvement creeps up a few percentage points a year which can then compound and transform our lives but there's never a Thursday in October in which it happens suddenly so you never read about it but you do read about all the wars and the pandemics and the the riots and the terrorist attacks so unless you are nerdy enough to get your view of the world from graphs and data you can miss the spectacular improvements that have taken place so I can understand how someone would disagree with you before they've read your book because they're biased by the media but what surprises me is that some people are still not convinced by your book even if they read it because I know there's like a lot of noise around your book from both the left to the right both find all sorts of things they don't like about it but reading it I'm not sure what they complain about indeed and of course the left and the right both have grievances about modern institutions the Grievances differ but for those on the hard left who believe that the modern neoliberal establishment is fundamentally corrupt to say that well things are better than they were 30 years ago or 100 years ago or 150 years ago is a kind of heresy in parallel there are big currents in the right that believe the enlightenment was a terrible mistake we were better off when we submitted to an authority higher than ourselves mainly the church but established social norms and institutions like the monarchy and the class system so there's a kind of a ideologized pessimism on both sides yeah so you are an optimist and you focus on progress and yet you're clearly very thoughtful about the fact that most people most of the time don't make much sense and suffer from the sorts of psychological biases that that people think about so I know you're interested in rationality what's your Global take on rationality yes I just completed a general education course at Harvard on rationality which covered the tools of rationality that I tend to think that all educated people should command any educated person should know what Bayesian reasoning is or a statistical decision Theory namely making a decision under uncertainty in a way that trades off the harm of false alarms with the harm of Mrs or how to tell correlation from causation how to avoid logical fallacies and critical thinking fallacies and so the question at the intersection of economics and psychology is in what ways are people rational and in what ways are they not so rational and so it poses an interesting scientific question of given that our species has transformed the world and discovered the secrets of life in the universe built amazing things how do we do it despite all of these cognitive infirmities and how can we make ourselves smarter so that sounds great the question I have is why does someone have to go to Harvard to get that class it seems like we should teach a class like that in public high schools I mean you've actually hit on one of my pet peeves which is how silly I think the math we teach to teenagers is when there's so much interesting valuable knowledge about you know whether it's Bayesian calculations or about the kind of simple data you use so effectively in your books yes I couldn't agree more and I do believe that it should be part of the high school curriculum I don't know if they still teach trigonometry I love trigonometry but you know you can't teach everything that only so many hours in the day and if it's a choice between trigonometry and say you know Bayesian reasoning or conditional probability it's just obvious what kinds of mathematics have the greatest impact both on our responsibilities as Citizens and the decisions that we make in our everyday lives um so I suspect you have a prodigious memory uh I'm going to give you a little quiz do you remember what I think is the only time we ever met my memory is not what it used to be I know that we have met and you're gonna have to fill me in okay yeah we met once in 2005 and we had lunch oh yes so that was it uh that was it Ted was it in England in Oxford yeah and I remember those days particularly vividly because it was one of the most traumatizing academic moments of my life so I had given a TED Talk previously that had gone very very well and everybody loved and I thought I was such a great speaker and so I was invited to do this second Ted Talk and I had five-year-old children at the time so I decided that the right way to give my TED Talk would be as a fable so I told a fable about car seats and I actually don't think it was as terrible as it went but what really set me up for the ultimate failure is that the speaker right before me was Richard Dawkins and he gave the most amazing 18 minute talk about the entire universe on his own home turf till like an audience that erupted with joy and Applause and I sat in the audience and I said wait you actually expect me to go up directly on stage now after he did that and tell my little Fable and I honestly wanted to sneak out of the room and never come back but I dutifully got up on the stage and to complete and utter silence for 18 minutes I spoke and I got off the stage and I've been trying to forget those 18 minutes ever since it was really maybe the most awful speaking experience I've ever had I have a similar experience at a different tent I had to speak after Hans rostling who later became a hero of mine as one of the people documenting human progress with creative Graphics but not only did he present just you know eye dazzling animated graphics on human progress but he ended his talk by swallowing a sword he really swallowed a sword that too was a as they say a tough act to follow thank you so one of the areas you're talking about is the environment and I think people are extremely pessimistic about the environment and yet I think you offer one of the most even-keeled thoughtful discussions of our current climate situation that I've heard in a long time could you share that with us yeah so it begins with acknowledging the scientific near consensus that the climate is warming that human activity is the cause and that things could get not only worse but much much worse if we fail to mitigate ongoing climate change the reason that climate change has occurred is that it's a undesirable byproduct of something that is desirable namely the capture of energy which allow large parts of the world to become richer and the advantages that we enjoy from burning fossil fuels starting with the Industrial Revolution the rest of the world is not going to forego particularly China India Indonesia big populist countries that are getting their first taste of affluence and are just not going to go back to poverty and the way out of poverty is the capture of energy so given that reality given our kind of existential situation of capturing energy or being miserably impoverished it looks to the development of carbon free energy which I argue should not be completely equated with Renewables like solar and wind because there is no energy economy that's scalable that could rely on solar and wind alone although it could change in the future if we have massive uh for energy storage but that's not going to happen anytime soon and so it Advocates nuclear power being in the mix because it is contrary to many people's Impressions it's probably the safest source of energy that despite the highly publicized disasters at Chernobyl and Fukushima those numbers pale in comparison to the number of people that are killed day in day out by a coal by both accidents in mining and transport and the disease burden from particulate matter that's emitted when coal is burned and that the problem of storing nuclear waste is a problem but it's actually a much more tractable problem than a massive waste that comes from coal mining and burning to say nothing of the fact that solar panels have a finite life just like your iPhone you have to replace it after a few years and so we're going to have massive quantities of rare Earths and glass and silicon and metal to deal with it really is amazing that the World Turns so forcibly against nuclear power exactly at the time when climate change was becoming set to force Germany being a great example of a very Green Country that did away with nuclear in order to in the short term import dirty coal from the United States it's really puzzling isn't it well to a psychologist is not because all the things that distort our assessment of risk such as highly Salient newsworthy examples intuitions of contamination the desire to completely eliminate one danger as opposed to reducing the aggregate Danger from all risks combined all of these are a kind of a perfect storm that turned the world away from the nuclear probably starting with Three Mile Island in 1979.

I know a celebrity who says that he blames climate change on Bruce Springsteen Bonnie Raitt and the Doobie Brothers for their excellent concert no nukes they turned the baby boomer generation against nuclear uh Joshua Goldstein and I argue that the Millennials and Generation Z should reject the baby boomer consensus that form their own climate policy that's more in touch with the statistical reality but anyway just to complete the thought because you asked me about climate change so I think part of it has to be technological not just the adoption of every energy technology that provides abundant scalable energy without carbon emissions but better still the development of new technologies and the great thing about technological solutions to climate change is that they can't be reversed by populist presidents so we could have a president that withdraws from the Paris Accord but you can't have a precedent that undoes a technological Discovery moreover if there's a technology that makes clean energy cheaper than dirty energy then no one has to be persuaded it's not politicized absolutely and the other side of the equation is how do we take the carbon that's there out of the air or in other ways do engineering figure out how to cool the Earth and you know I believe deeply in markets and I think they work well but it seems to me there's a complete failure of our market right now in that Dimension so there are I don't know a dozen 30 entrepreneurial scientists who are jealously guarding their intellectual capital and working independently to try to come up with the solution that will work out carbon capture and they'll be able to capture themselves all of the money that comes with solving that problem but in an existential crisis like climate change it seems like a terrible model for science it seems like something much more like the Manhattan Project Where We Gather the top 300 scientists in the world together and encourage them incentivize them to work collectively would be a better model what do you think of that proposal I I couldn't agree more it's just in the nature of markets if they don't work miracles you can be a completely committed acknowledger of the benefits of Marcus and say well but there are certain things that only governments can do and and I agree this is one of them yeah or not even government so I'm kind of given up on the US government right now but I've pitched three or four of the richest people in the United States on this idea and every one of them was intrigued but not one of them was willing to pull the trigger they have the kind of resources where they can determine how to solve public goods problems and so that seemed to me the path of least resistance that's very interesting but I agree even though there's a huge backlash now against billionaire philanthropists the number of best sellers saying well the government should do it but the problem with the democracy is that when it works the people get what they want and people don't always want what's best for the planet at least not all at the same time not all right now and a democratically responsive government may not have the freedom to experiment to take chances to develop not so popular options foreign so let's change gears one thing I hadn't expected from you reading your books was how funny you can be when you turn your attention to being funny I think a great example comes from another one of your books called the better angels of our nature which argues that violence has greatly decreased over time and that doesn't strike me as being a very funny topic but your synopsis of the Old Testament in that book made me laugh so hard that I could barely breathe yeah not everyone found that passage so funny but but yeah so what I simply did is I uh went through the major stories of the Hebrew Bible the Old Testament and I just described them pretty factually I had intended this as kind of a sanity check because by making the argument that violence has declined over the course of history I just want to remind people of how violent earlier times were and the Hebrew Bible was is a fine example so I told the story of Adam and Ethan Cain and Abel pretty much sticking to the King James translation came talked with Abel whose brother and it came to pass when they were in the field and King rose up against Abel and slew him with the world population of exactly four that works out to a homicide rate of 25 which is about a thousand times higher than the equivalent rates in Western countries today I then talked about the first of many genocides in the Bible the noachian fled The Binding of Isaac the selling of Dinah Jacob's daughter in marriage can you tell the dinosaur I love the dinosaur yes Isaac's son Jacob has a daughter Dina Dina is kidnapped and raped apparently a customary form of courtship at the time since the rapist family then offers to purchase her from her own family as a wife for the rapist Dinah's Brothers explained that an important moral principle stands in the way of this transaction the rapist is uncircumcised so they make a counteroffer if all the men in the rapist's hometown cut off their foreskins Dinah will be theirs while the men are incapacitated with bleeding penises the brothers invade the city plunder and destroy it Master them in and carry off the women and children when Jacob worries that neighboring tribes May attack them in Revenge his sons explained that it was worth the risk should our sister be treated like a soon afterward they reiterate their commitment to Family Values by selling their brother Joseph into slavery I mean funny or not funny and I grew up with the idea that historically the Hebrew Bible was what first introduced morality of the world when I read some of the passages as an adult it's horrifying and that's what's in the the Old Testament it made me realize that for all of the pageantry the community the the beauty of religious observance it's a big mistake to think of the Bible as a source of our moral values it's really interesting I had never read the Bible I was raised completely non-religiously until maybe three months ago the first time I ever opened up the Old Testament and I was shocked I mean I I didn't see it even as clearly as you lay it out here but it was really surprising to me the role of Vengeance and how often humans fail it was really surprising and it jabbed so well with what you just described as your interpretation and your caveats yes I mean the god of the Old Testament basically works by the moral code of the Corleone he's namely yeah you do something that insults me and they'll murder you and your family blood Revenge it was the highest moral value now I mean this is not to cast aspersions on Jews and Christians today quite the opposite the point is that we have progressed but we view it fortunately through Modern Eyes there's a kind of benign hypocrisy where we say we believe it but thank goodness we don't and this actually connects to a theme that I've been pondering more recently we as humans have two modes of believing things there's the things that impinge on our everyday lives a kind of world of fact and falsehood where we really do have a commitment to truth we really do want to know exactly what's happened but for most of human history and still today their whole spheres where we just don't really insist on knowing what's true or what's false we want morally uplifting narratives and dramatically compelling narratives yeah the enlightenment I think you would argue was the point where truth became important even if it wasn't the truth about where your crops going to grow or not but a broader truth would you agree that essentially was one of the most important features of the Enlightenment absolutely that's right and before the Scientific Revolution that it's not just you know how to grow crops how to keep your kids out of danger but it's also what's happening halfway around the world what happened thousands of years ago what's going to happen thousands of years from now where the same attitude that we take to our everyday lives we should apply to everything but one can understand why that's such a recent and exotic mindset for most of human history we had no way of knowing what happened you could believe anything you want an educated person before the Scientific Revolution could very well believe that there are unicorns and werewolves that comets and eclipses are portents of the future that a dead man will bleed in the presence of a murder weapon or a murderer beliefs that now we you think of as primitive superstitious magical but they were the conventional understanding of the day but once there is science once there is journalism once there is scholarship once there is history then you can expand the domain of the real to Realms where Common Sense didn't have a place for it it's a great reminder about how difficult it is for individuals to learn the truth so we benefit enormously of course from the brilliant Scholars who came before us yeah indeed and that Revelation that our everyday experience is not a reliable Guide to the ultimate nature of reality is a major transition in thought so you've exhibited a lot of intellectual bravery I think over your career you've been willing to stand up for the things you believe to be true and you've been willing to do it in situations where there seems honestly to an outsider to be very little for you to gain I think that the one that comes to mind to me is when Larry Summers had made comments about women in math and whether those were true or false looking at the situation it would seem to make a lot of sense to keep your mouth shut because it was only going to get you in trouble but you were willing to talk can you tell me a little bit about your logic in that setting and why you came forward to I think so much to my own retroactive surprise I seem to have a taste for controversy because I'm not a confrontational person I'm a polite Canadian I like to get along but in my professional career I've often jumped into controversies not necessarily political ones but ones with in my own field I was involved in the imagery debate of the 70s and 80s that is our mental images more like pictures or more light sentences the debate over what is or isn't innate in language that allows kids to acquire their mother tongue involving Noam Chomsky and his critics so I do have a taste for the areas that are still under dispute where I like to think that I have a contribution to making clarifying things sometimes by taking positions that are not the consensus but I manage my controversy portfolio carefully lots of people say will you blurb my book with this outrageous opinion or that hot button and no I don't just sign on to any old controversy and in the case of Larry Summers part of it was that he based some of his arguments on a chapter in one of my books called gender in the blank slate the modern denial of human nature so I felt I already had a dog in that fight also it offended me the way in which Summers was distorted by highly intelligent people he made a statistical argument that the variance among male abilities was greater than the variance among female abilities in spatial cognition so you have a higher percentage of men at the high end and at the low end even if the means were the same and even if there were at any given level of ability you'd obviously have both men and women that was turned into women can't do math by some professors of science who clearly had no particular interest in accurate citation but wanted to get people riled up it does not mean that every man is better at spatial ability than every woman there are lots and lots of women who are better than the average man and conversely women are on average better at verbal fluency and arithmetic calculation than men still that doesn't mean that every woman is better than every man there are many men who are better than the average woman you're symmetrical just that it did offend me that that kind of basic way of just thinking about exceptions versus Central Tendencies was expunged from this debate in the service of moral outrage do you care whether people are convinced by the argument you make I do in the sense that you know I think it is part of intellectual responsibility we all want to find the truth the only route to knowledge is to propose hypotheses and see if they withstand attempts to falsify them that's the way science works that's the way knowledge works and so it's good to be controversial in the sense of proposing a hypothesis that people can evaluate that if it's true it Blends in sight no guarantee as to which ones are going to be true and I make an argument because I think that it's to the best of my judgment true and explanatory that is it gives us Insight it allows us to think clearly about something and of course I know I might be wrong but if I don't persuade people there's a sense in which I haven't done my job even though I know I won't persuade people my old Mentor Gary Becker thinking back to a situation where I was caught in the crosshairs of moral outrage I think it had to do with climate change but I can't remember the particular details and he pulled me into his office and he said I'm so jealous of you and I said why are you jealous he said oh all these people are so mad at you they're everyone's furious at you you're getting all this attention the only thing I hate I hate to be ignored being ignored is the worst my literary agent said something similar to me now of course you know you don't want just want to rile people up you really want to make a case for something where you think the evidence points foreign you're listening to people I mostly admire with Steve Levitt and his conversation with psychologists and linguist Stephen Pinker they'll return after this short break so I've read a few of your academic Linguistics papers and let me just say I found them pretty inscrutable I would not have predicted 20 years later you would be writing a stream of best-selling books and I know that's part of linguistics it's not your fault but I'm curious why are languages so complicated do languages have to be as complicated as they are so language does have a lot of complexity because it's the way we express complex thoughts and that's what it evolved in historically developed to do that's what you and I are doing right now I mean these are complicated thoughts and you and I are just going wow wow we're making noise with our mouths and if we succeed people are thinking those thoughts too that's amazing absolutely okay I give you that let me tell you about different level of complexity though so for instance you've studied irregular verbs why are there irregular verbs what is the point of verb being irregular or take a language like German where you have genders going with nouns that have nothing to do with anything do you have an understanding of why that complexity exists in language it's a profound question and uh here's my best stab at it there are really two components to language just as there are two components to computation one of them is memory there's just a lot of things that you just commit to wrote and that includes our vocabulary we know when the order of tens of thousands of words in each one of them is as arbitrary as a phone number there's just no way you could know the dog means dog as opposed to a zebra other than the fact that you memorized it as a child but then there's also algorithms There are rules for combining words so that we can express new combinations of ideas things that have never occurred to anyone and that's what gives language its power we don't have to just regurgitate the same ideas over and over again we can share new discoveries new insights new stories and here's the third part of the explanation which is that a language has to be shared for it to be useful if I spoke a beautifully expressive language and I was the only person who spoke it I may as well not know it at all it would be useless so we've got to share the code within the community so that what one person says another person can understand and it's not like a computer programming language where someone sits down The rules it's kind of a Wiki that develops historically that's picked up by exposure always with some probability that something will be forgotten in a given generation that it will be misunderstood misanalyzed so those are the three ingredients you've got memory you've got rules and you've got community sharing and historical transmission you put them together and things that start off nice and tidy and neat and Rule governed can then as people distort them as they play Broken telephone things can get complicated and exceptions pile up and you memorize the exceptions so you think that languages go from simple to complicated I sort of have the impression the opposite was true both happen which would resolve the Paradox and I think you're correct in noting that that if it was just simple the complex then uh languages get more and more and more and more complicated and parts of languages do and then they sometimes collapse into Simplicity and then in other parts of the language the exceptions accumulate the conditions proliferate often until that reaches a breaking point so it's kind of a random walk in English we have very primitive gender and even more primitive case we only have the distinction between say he and him and I and me in the case system other languages you've got to memorize a dozen cases and a lot of them exceptions on the other hand English has a pretty complicated set of rules for asking a question we make things really complicated in one part of the language even as we simplify another part English is becoming the world language is it well suited for that task group would other languages do better yeah I think one of the misconceptions about languages is that some languages are inherently more suited for being a lingua Franca in some domain than others and that's why they become influential you know German was originally the language of Science and French the language of diplomacy and the major factor is uh history and politics English is the world's dominant language because originally the Sun never said on the British Empire and then the United States after World War II just became the PowerHouse of culture and technology and business and whatever language the dominant Empire speaks everyone learns so English is winning in some sense but is there a consensus among linguists about the language that if it could be the lingua Franca would be the best language to be a global language I mean is it Esperanto no it isn't Esperanto although it might be partly because in the design of any language there are trade-offs and one of the reasons that you can't have a perfect language is that there's no single Criterion of perfection and an obvious example is the trade-off between speakers and hearers so from the point of view of a hearer every syllable should be perfectly articulated so that there's no chance of misunderstanding on the other hand from the point of a speaker you want to get your words out as quickly as possible and not have your tongue do too many gymnastics they're in Conflict they can't both be happy all the time and a lot of the history of language the reason that we don't sound like Shakespeare and Shakespeare didn't sound like Chaucer is that people are always slurring some parts of language and then sometimes it goes viral and that distinction gets lost as everyone slurs it in the same way that's one of the reasons why we have so many silent letters in English they weren't always silent Nightingale used to be that's why we have the GH that's why we have the e at the end but it became too much of a tongue twister and lazy speakers won the day spelling didn't keep up and so we've got all this crazy English spelling on the other hand if you just become a nation of mumblers then no one will understand what you're saying and so some distinctions get exaggerated and embroidered but since no one's in charge no one's deciding what is the perfect trade-off then you've got this constant churning this constant emotion so no language could be perfect from the point of view of both speakers and hearers that's really interesting I never thought about that here's a different kind of question and I don't know if you know the answer to it or not so there is a point in child development where I think kids can think and I think they understand much of what they see around them but my sense is they have very limited language capabilities and I'm interested to know what the state of thought is about the ability to think in the absence of words if that makes any sense oh absolutely makes sense an utterly profound observation and it's one of the biggest most important refutations of the idea that all thought consists of language for one thing we know from experiments that pre-linguistic infants do have often a sophisticated understanding of cause and effect of personal agency of Persistence of objects because when you think about it how could a child acquire a language if they couldn't think until they had the language and I've long maintained that the way that language learning works in kids is that they're not just cryptographers it's not just they're hearing a stream of sound and they look for statistical patterns but they're always correlating the sounds with content with meaning that is they're short enough to have a reasonable guess as to what the speaker meant when they said something and they correlate their interpretation of the speaker's intent with a stream of sound coming out of their mouths and that's how they crack the code let me um End by asking for your advice on learning a language as an adult is there anything in your background or research that can help someone like me who say try to learn German because my wife is German do it better yeah you're right in pointing to adulthood as an impediment a couple of years ago I published the most massive study yet with Josh Hartson and Josh Tenenbaum where we capitalized on a language quiz that Josh Hartson put online that got two-thirds of a million respondents and because the demographics of the questionnaire are included at what age did you begin to speak English and for how long have you been at it we were able to dive into the data to answer the question that many people were curious about is namely do kids really have an advantage in how long does it last and the answer is they do but at last surprisingly long with some mathematical modeling we estimated that the change in the underlying ability to soak up the grammar of a new language only takes place around 17.

now if you start at 12 you're at a disadvantage because it takes more than five years to master all the ins and outs of the language so you're only doing it at top capacity for five of the necessary years but to our own surprise a window is longer than people think now what about if you're older than 17 well the window doesn't shut there's a decline so it's still possible I would say that to make up for the fact that presumably the underlying circuitry isn't as plastic as it used to be when we were kids a number of strategies have to be used and one of them of course is using the language in context in a conversational situation because this is one of the things I have to confess that I'm not much of a polyglot myself I have some French some Spanish some Hebrew but I'm often paralyzed because a lot of my learning was kind of book learning and then when I'm just plunked in a situation and there's all this social stuff going on I don't want to look like an idiot I don't want to insult people I don't want to condescend and so kind of lubricating the path to exploring the whole language often depends on these little social rituals that get you going so that's an essential part of it but also combined with making up for the decline in underlying fluency and facility by applying intellect by remembering the irregularities and by reading and developing conscious rules to help make up for the fact that it doesn't come as naturally as when we were kids yeah with German I've tried quite hard on German and I've become a pretty good reader I read it maybe the eighth grade level in German but I speak like a three-year-old which is really embarrassing when I'm in public settings as Mark Twain said there are more exceptions to the rule than instances of it I don't know if you've read Twain's uh essay the horrors of the German language but if you haven't it will make you laugh out loud yeah I I have not but I will German has actually been quite a pleasure for me compared to trying to learn Mandarin when I adopted two daughters from China I thought that I should try to learn Mandarin for my trip to China and again I worked for me pretty hard I probably spent a half an hour a day for six to nine months trying to learn Mandarin and I went to China and I literally did not understand a word that someone said and I literally was not understood a single word that I said after that investment so I waited three or four years till adopting my next daughter and I literally did not think about Mandarin one second in between until I got on the airplane and I spent maybe three or four hours and I memorized and practiced three sentences and I made sure I could say them really really well and ever every single conversation I had in China for the next two weeks I started by saying the first sentence and no matter what someone said back to me I said the second sentence and no matter what they said back to me I said the third sentence and it was the most amazing success in the world my sentences were like I'm from the United States this is my daughter I'm adopting her and bringing back home like those were the gist of my three senses and it turned out that people were very happy I don't know what they said to me but they smiled and the funny thing about was the Americans who are with me and watch this maybe a week into it one of them said to me God is unbelievable how fluent you are in Chinese like every time you talk to someone you can answer their questions and they just understand what you're saying and I never shared with that person that I literally said the same three sentences in every conversation that I'd had over the two weeks oh that's a fantastic story and it does underscore the fact that language is used in a social context and to break the ice you just have to be able to begin a conversation and act like a competent human this is above and beyond knowing the rules and the irregularities and so on all right last question it seems to me you've lived a really good life do you have advice about living a good life one is that you've got to live a life of a certain amount of benign hypocrisy where you paper over some differences for the sake of peace and harmony we'll never get to the ground Truth where everyone agrees on everything human conflict is inevitable that um this is I think a lesson from evolutionary biology we don't all want the same things and that that itself is something to be managed perhaps one other thing is to be grateful for what's gone right there'll always be things that go wrong and to appreciate when things are going right and not always focus on the remaining problems and to treat problems as things to be solved never perfectly but we've solved problems in the past collectively
