11 core rationalist skills – from LessWrong

An excellent way to improve one's skill as a rationalist is to identify one's strengths and weaknesses, and then expend effort on the things that one can most effectively improve (which are often the areas where one is weakest). This seems especially useful if one is very specific about the parts of rationality, if one describes them in detail.

In order to facilitate improving my own and others' rationality, I am posting this list of 11 core rationalist skills, thanks almost entirely to Anna Salamon.

  • Keep your eyes on the prize. Focus your modeling efforts on the issues most relevant to your goals. Be able to quickly refocus a train of thought or discussion on the most important issues, and be able and willing to quickly kill tempting tangents. Periodically stop and ask yourself "Is what I am thinking about at the moment really an effective way to achieve my stated goals?".
  • Entangle yourself with the evidence. Realize that true opinions don't come from nowhere and can't just be painted in by choice or intuition or consensus. Realize that it is information-theoretically impossible to reliably get true beliefs unless you actually get reliably pushed around by the evidence. Distinguish between knowledge and feelings.
  • Be Curious: Look for interesting details; resist cached thoughts; respond to unexpected observations and thoughts. Learn to acquire interesting angles, and to make connections to the task at hand.
  • Aumann-update: Update to the right extent from others' opinions. Borrow reasonable practices for grocery shopping, social interaction, etc from those who have already worked out what the best way to do these things is. Take relevant experts seriously. Use outside views to estimate the outcome of one's own projects and the merit of one's own clever ideas. Be willing to depart from consensus in cases where there is sufficient evidence that the consensus is mistaken or that the common practice doesn't serve its ostensible purposes. Have correct models of the causes of others’ beliefs and psychological states, so that you can tell the difference between cases where the vast majority of people believe falsehoods for some specific reason, and cases where the vast majority actually knows best.
  • Know standard Biases: Have conscious knowledge of common human error patterns, including theheuristics and biases literature; practice using this knowledge in real-world situations to identify probable errors; practice making predictions and update from the track record of your own accurate and inaccurate judgments.
  • Know Probability theory: Have conscious knowledge of probability theory; practice applying probability theory in real-world instances and seeing e.g. how much to penalize conjunctions, how to regress to the mean, etc.
  • Know your own mind: Have a moment-to-moment awareness of your own emotions and of the motivations guiding your thoughts. (Are you searching for justifications? Shying away from certain considerations out of fear?) Be willing to acknowledge all of yourself, including the petty and unsavory parts. Knowledge of your own track record of accurate and inaccurate predictions, including in cases where fear, pride, etc. were strong.
  • Be well calibrated: Avoid over- and under-confidence. Know how much to trust your judgments in different circumstances. Keep track of many levels of confidence, precision, and surprisingness; dare to predict as much as you can, and update as you test the limits of your knowledge. Develop as precise a world-model as you can manage. (Tom McCabe wrote a quiz to test some simple aspects of your calibration.)
  • Use analytic philosophy: understand the habits of thought taught in analytic philosophy; the habit of following out lines of thought, of taking on one issue at a time, of searching for counter-examples, and of carefully keeping distinct concepts distinct (e.g. not confusing heat and temperature; free will and lack of determinism; systems for talking about Peano arithmetic and systems for talking about systems for talking about Peano arithmetic).
  • Resist Thoughtcrime. Keep truth and virtue utterly distinct in your mind. Give no quarter to claims of the sort "I must believe X, because otherwise I will be {racist / without morality / at risk of coming late to work/ kicked out of the group / similar to stupid people}". Decide that it is better to merely lie to others than to lie to others and to yourself. Realize that goals and world maps can be separated; one can pursue the goal of fighting against climate change without deliberately fooling oneself into having too high an estimate (given the evidence) of the probability that the anthropogenic climate change hypothesis is correct.

Transhumanism, personal immortality and the prospect of technologically enabled utopia

We live in a universe that works on physical laws - simple rules that determine how quantum mechanical amplitude evolves over time. The universe is, at its lowest level, rather like a lego kit with a comparatively small number of bricks, or to put it another way, the universe is a lot like Conway's Game of Life. This surprising (and highly counterintuitive) fact has an even more surprising implication: there is no fundamental law that prevents us from improving our lives to arbitrarily high levels of personal well-being. There is no fundamental reason why we cannot create a utopia - to shape the little blocks that the universe is made out of into an arrangement that satisfies our true desires to the maximal extent possible.

Death is not a fundamental fact of existence, it is not a deliberate plan hatched by a careful creator who works in mysterious ways, it is not a punishment or a way to teach us a lesson. It is simply an accident of evolution, and it is perfectly possible (in principle!) to get rid of that particular accident. Likewise human suffering: from the minor annoyances to the agony of losing a loved-one or being betrayed by a friend or partner. Likewise the problems that we humans probably don't even realize that we have, because they are as ubiquitous and invisible to us as water is to a fish. Likewise the extreme suffering of the poorest 1 billion humans.

Transhumanism is simply the idea that we can and should use technology to enable human beings to live the lives that they would, upon reflection, choose. Nick Bostrom put this set of ideas particularly eloquently in his Letter from Utopia:

How can I tell you about Utopia and not leave you nonplussed? What words could convey the wonder? What inflections express our happiness? What points overcome your skepticism? My pen, I fear, is as unequal to the task as if I had tried to use it against a charging elephant.

Have you ever known a moment of bliss? On the rapids of inspiration, maybe, where your hands were guided by a greater force to trace the shapes of truth and beauty? Or perhaps you found such a moment in the ecstasy of love? Or in a glorious success achieved with good friends? Or in splendid conversation on a vine-overhung terrace one star-appointed night? Or perhaps there was a song or a melody that smuggled itself into your heart, setting it alight with kaleidoscopic emotion? Or during worship?

If you have experienced such a moment, experienced the best type of such a moment, then a certain idle but sincere thought may have presented itself to you: “Oh Heaven! I didn’t realize it could feel like this. This is on a different level, so very much more real and worthwhile. Why can’t it be like this always? Why must good times end? I was sleeping; now I am awake.”

RokoMijic.com is up

My personal website is now up at:

My website covers similar topics to this blog, but hopefully in a more "official" style. It currently hosts my report on AI and the Semantic Web that I spent the academic year 2008-2009 writing, and my essay on operads and the opetopes that I wrote for my final mathematics examination at Cambridge.

I'm hoping to add more essays and preprints to the website as I complete them, including a preprint of a paper on evolutionary pressures on uploaded humans that I am currently writing.

Why the Fuss About Intelligence?

Part two in a GOOD miniseries on the singularity by Michael Anissimov and Roko Mijic. New posts every Monday from November 16 to January 23.

Last time, we took our first look at the concept of the technological singularity—a point in time when a genuinely smarter-than-human intelligence is developed—and saw that it is an old idea which has gained momentum and is more relevant today than ever before. Now we’ll look at why smarter than human intelligence is worthy of more attention than other futuristic technologies such as spaceflight or cleaner energy technology which, on the surface, seem just as exciting.

Why are singularity researchers so concerned about the prospect of smarter-than-human intelligence? To answer this question, we must first unlearn something we all instinctively know: We must unlearn the idea that human intelligence is nothing special. In everyday life, our human intelligence—including our language ability, social intelligence, strategic thinking, planning ability, rationality, and scientific skill—is ubiquitous, so we take it for granted. But it is amazingly powerful compared to the level of intelligence that other higher animals have. There are no chimps that win Nobel Prizes in physics, no dogs that are CEOs of major corporations.

Once one realizes that the notion of human intelligence encompasses every useful skill that we perform with our brains, one begins to see that intelligence is the reason that human beings have taken control of much of the planet’s land mass, constructed skyscrapers, developed economies, and invented nuclear weapons. The speed of the human takeover of earth was startling relative to the slow changes that came before it. In just a few tens of thousands of years, humans took control of a 4-billion-year-old biosphere. The effect of human intelligence on many other species living on this planet has been fatal: Human beings have caused the extinction of millions of other species, primarily because of the power that our intelligence brings. This historical perspective is key to understanding what the technological singularity is about. It isn’t about shiny new gadgets or mundane, Jetsons-style futurism where humans live the same lifestyle as today but against a flashier background. It is about the next iteration of the most powerful force in the universe: intelligence. The correct metaphor for the singularity is not the image of a shiny, chrome-plated robot, it is the leap from wild animals to human societies, but this time with humans as the starting point.

In the 21st century, cognitive science or artificial intelligence researchers may find out how to construct an intelligence that surpasses ours in the same way human intelligence surpasses that of chimps. Given what happened the last time a new level of intelligence emerged (the rapid rise of humans 12,000 years ago), this is likely to be the most important event in the history of the human race. We should expect smarter-than-human intelligence to wield immense power—to be able to think through complex problems in a fraction of a second, to uniformly outclass humans in mathematics, physics, and computer science, and to build technological artifacts with superlative properties. Smarter-than-human intelligences will stand a good chance of solving the problem of how to make themselves even smarter, spiraling into ever greater heights of intelligence.

Genuinely smarter beings could solve many of the problems that humans currently find hard to deal with, such as involuntary death, disease and aging, global inequality and poverty, war and environmental degradation. If a smarter-than-human intelligence were put to the task of solving these human problems, it might not be able to solve all of them, but I bet that it could do a much better job than we are. We should expect that the result of a sequence of self-improving intelligences could probably cure all human diseases, harvest the entire energy output of the sun, and colonize the galaxy at a speed approaching the speed of light. If this kind of power seems unreasonable to you, then I agree—but reality is not limited by our very human sense of reasonableness.

  • 25 Everyday Technologies That Came from NASA
    Though associated mainly with aerospace innovations, NASA holds a significant influence over daily life as well. Many people do not realize that everything from toys to sunglasses and even horseshoes have benefitted from technologies originally intended for astronauts, shuttle flights, and other elements of space exploration. While some inventions stem directly from NASA and its collaborations, others simply involve vast improvements to existing designs. The following list contains a combination of technologies that went straight from NASA to consumers as well as ones that went on to streamline articles that were already available.
  • Bionic supermen of sport | CTV Olympics
    Athletes with disabilities can now be transformed with the addition of high-tech prostheses which can actually outdo the human equivalents
  • Man trapped in a 23-year 'coma' was conscious entire time
    Doctors in Belgium have freed a hospital patient from a 23-year nightmare after discovering the man had been misdiagnosed with a coma.
  • Meat without animals? Science says yes! | Current
    Winston Churchill once predicted that it would be possible to grow chicken breasts and wings more efficiently without having to keep an actual chicken. And in fact scientists have since figured out how to grow tiny nuggets of lab meat and say it will one day be possible to produce steaks in vats, sans any livestock.

    Can nanotechnology be sustainable? At the site, Forumforthefuture.org, under the section Green Futures, Peter Madden argues that nanotechnology can contribute to sustainability. But the article doesn't sit well with me -- why? Not because I'm a technophobe -- I love technology (except when it doesn't work, then I hate it).

    It bugs me because I can't tell what he means by sustainability.

    Who or what is being sustained? Humanity? Our Environment? The Earth? The Nanobots? Self-sustaining technology?

    And who controls or decides what be will be sustained?

    Don't get me wrong -- I do think there is such a thing as Green Nanotechnology; in fact Springer has just started a Journal of Green Nanotechnology.

    I just don't like to see sustainability used as a feel-good buzzword.

    Several key principles have emerged to guide sustainability efforts, including intergenerational equity, integrating environmental, social and economic sectors when developing sustainability policies, and preventing irreversible long-term damage to ecosystems and human health.

    The article does have one good point, though: In the end, it is how we decide to apply nanotechnology that will determine its true sustainability impact.

    How Americans spent themselves into ruin… but saved the world

    David Brin is a Sentient Developments guest blogger.

    In the 1/1/24 edition of the Silicon Valley newspaper and online journal Metroactive, I have an editorial describing how the American consumer came to propel the export-driven development of Japan, Korea, Malaysia, China and now India. That process, spanning more than six decades, is almost always portrayed -- especially in Asia -- as having come about as a result of eastern cleverness, in catering to the insatiable material appetites of decadent westerners. But there is a far more interesting, complex, and even inspiring explanation for how the greatest wealth transfer of all time -- which has lifted several billion people out of poverty -- actually came about. I reveal how George Marshall and the United States chose, in 1946, to behave differently from any other "pax" empire, and thereby changed the world.

    I'll now repost that essay here, in expanded form.

    If your politics operate on reflex - from either left or right - you are likely to find something here that will offend. But please, dear fellow believers in tomorrow, bear in mind that I'm an internationalist who opposed jingo-chauvinists, all his life.

    And yet, I feel it is long past time that someone spoke up in defense of Pax Americana.

    The Far-Right's Caricature Version of Pax Americana

    Sure, that phrase (PA) fell into disrepute during the era of the mad neocons, whose misrule left the United States far worse off by every clear metric of national health. During their time in near-total power, steering the American ship of state, fellows like Richard Cheney, Richard Perle, Kenneth Adelman and their ilk made a point of proclaiming imperial triumphalism - exoling an America invested with sacred, perfect and permanent rights of planet-wide dominance, based upon inherent qualities that were said to be unaffected by any objective-reality considerations, like budgets or geography; like world opinion or the end of the Cold War; like science or technology; like rationality or morality or the physical well-being of our troops.

    Indeed, the only factor that they felt might undermine America’s manifestly-destined and eternal preeminence could be a failure of will, should the wimpy liberals ever have their way. But if led with a firm-jawed determination to bull past all obstacles, the American pax could linger indefinitely, with all the privileges of governing world affairs and few of the responsibilities or cares.

    Sure, it has been proper to oppose the policies of such deeply delusional men -- policies which unambiguously and uniformly brought ruin to the very things they claimed to hold dear. Capitalism, freedom, fiscal and national health, as well as U.S. influence in the world all plummeted under their rule. (These metrics all skyrocketed under Bill Clinton, whose endeavor in the Balkans was inarguably one of Pax Americana's finest hours.)

    But The Left Goes Too Far The Other Way

    And yet, something is very wrong with the unselective manner in which some folks on the other side have allowed those neocon nincompoops to define the argument. It is an unfortunate habit of the left to assume that any appreciation of the American contribution to human civilization must be inherently fascistic. This reflexive self-loathing has given (unnecessarily) a huge weapon to the right, in their ongoing treason-campaign called "Culture War," allowing them to retain millions of supporters who might otherwise have abandoned them.

    By abrogating the natural human phenomenon of patriotic pride, these fools on the left have allowed guys like Sean Hannity to claim love-of-country as a sole monopoly of the right! If they get away with pushing simplistic “greatest nation ever” rants and portraying themselves as the implicit opposite of homeland-hating liberals, that gift comes gratis from the left.

    Moreover, there is another reason for liberals to re-examine this reflex and to find good -- and even great -- things to proclaim about America. Because, without any doubt, America deserves it. Yes, self-criticism is a useful tonic, and there definitely were crimes committed, during our time on top. Nevertheless, the net effects of Pax Americana have been generally positive, compared against every single previous era in human history.

    This can be proved, with just a single example -- one that was as decisive as it is ironic, and that has spanned an entire lifespan.

    The Miracle of 1946

    Mr. Wu Jianmin is a professor at China Foreign Affairs University and Chairman of the Shanghai Centre of International Studies. A smart fellow whose observations about the world well-merit close attention. Specifically, in a recent edition of the online journal The Globalist, Wu Jianmin's brief appraisal of "A Chinese Perspective on a Changing World" was insightful and much appreciated.

    However I feel a need to quibble with one of his statements, which reflected a widespread assumption held all over the world:

    "After the Second World War, things started to change. Japan was the first to rise in Asia. We Asians are grateful to Japan for inventing this export-oriented development model, which helped initiate the process of Asia’s rise."

    In fact, with due respect for their industriousness, ingenuity and determination, the Japanese invented no such thing. The initiators of export-driven world development were two military and diplomatic leaders of Pax American at its very peak: George Marshall, who was Secretary of State under President Harry Truman and Gen. Douglas MacArthur, during his time as military governor of Japan, in the ravaged aftermath of the Second World War.

    While Marshall crafted a historically unprecedented, receptively open trade policy called “counter-mercantilism” (I’ll explain in a minute), MacArthur vigorously pushed the creation of Japanese export-oriented industries, establishing the model of what was to come. Instead of doing what all other victorious conquerors had done – looting the defeated enemy -- the clearly stated intention was for the United States to lift up their prostrate foe, first with direct aid. And then, over the longer term, with trade.

    (One might well add a third American hero, W. Edwards Deming, whose teachings about industrial process -- especially the importance of high standards of quality control -- were profoundly influential in Japan, helping transform Japanese products from stereotypes of shoddiness into icons of manufacturing excellence.)

    Look, lest there be any misunderstanding, I am not downplaying the importance of Japanese, Korean, Malaysian, Chinese and Indian efforts to uplift themselves through the hard work of hundreds of millions who labored in sweatshops making toys and clothes for U.S. consumers. Without any doubt, those workers... (like the generations who built America, before 1950, in the sooty factories of Detroit and Pittsburgh)... and their innovative managers, were far more heroic and directly responsible for the last six decades of world development than American consumers, pushing overflowing carts through WalMart.

    Nevertheless, those consumers —plus the trade policies that made the WalMart Tsunami possible, plus a fantastically generous and nearly unrestricted flow of intellectual capital from west to east — all played crucial roles in this process that lifted billions of people out of grinding, hopeless poverty. Moreover, it now seems long past time to realize how unique all of this was, in the sad litany of human civilization.

    The Thing About Empires

    Let's step back a little. First off, if you scan across recorded history, you'll find that most people who lived in agricultural societies endured either of two kinds of global situations. There were periods of imperium and periods of chaos. A lot of the empires were brutal, stultifying and awful, but at least cities didn't burn that often, while the empire maintained order. Families got to raise their kids and work hard and engage in trade. Even if you belonged to an oppressed subject people, your odds of survival, and bettering yourself, were better under the rule of an imperial "pax."

    That doesn't mean the empires were wise! Often, they behaved in smug, childish, and tyrannical ways that, while conforming to ornery human nature, also laid seeds for their own destruction. Today, I want to focus on one of these bad habits, in particular.

    The annals of five continents show that, whenever a nation became overwhelmingly strong, it tended to forge mercantilist-style trade networks that favored home industries and capital inflows, at the expense of those living in in satrapies and dependent areas.

    The Romans did this, insisting that rivers of gold and silver stream into the imperial city. So did the Hellenists, Persians, Moghuls... and so did every Chinese imperial dynasty. This kind of behavior, by Pax Brittanica, was one of the chief complaints against Britain by both John Hancock and Mohandas Ganhdi.

    Adam Smith called mercantilism a foul habit, that was based in human nature. A natural outcome of empire, it over the long run almost inevitably contributed to self-destruction. But alas, everybody did it, when they could. Except just once.

    The Exception to the Rule of Imperial Mercantilism

    In fact, there has been only one top-nation that ever avoided the addiction to imperial mercantilism, and that was the United States of America. Upon finding itself the overwhelmingly dominant power, at the end of World War II, the U.S. had ample opportunity to impose its own vision upon the system of international trade. And it did. Only, at this crucial moment, something special happened.

    At the behest of Marshall and his advisors. America became the first pax-power in history to deliberately establish counter-mercantilist commerce flows. A trade regime that favored the manufactures of many foreign/poor countries over those in the homeland. Nations crippled by war, or by millennia of mismanagement, were allowed to maintain high tariffs, keeping out American manufactures, while sending shiploads from their own factories to the U.S., almost duty free.

    Moreover, despite the ongoing political tussle of two political parties and sometimes noisy aggravation over ever-mounting deficits, each administration since Marshall's time kept fealty with this compact -- to such a degree that the world's peoples by now simply take it for granted.
    Forgetting all of history and ignoring the self-destructive behavior of other empires, we all have tended to assume that counter-mercantilist trade flows are somehow a natural state of affairs! But they aren't. They are an invention, as unique and new and as American as the airplane, or the photocopier, or rock n' roll.

    Why Did This Happen?

    Now, of course, more than pure altruism may have been involved in the decision to create counter-mercantilism. The Democratic Party, under Truman, and Republican moderates, such as President Dwight Eisenhower, held fresh and painful memories of the Hawley-Smoot tariffs, instituted under Herbert Hoover and the Republican Congress of 1930, which triggered a trade war that deepened the Great Depression. Both Truman and Ike saw trade as wholesome for world prosperity -- and as a tonic to unite world peoples against Soviet expansionism.

    (Indeed, as another example of his farsighted ability to plan ahead for decades, Marshall also designed the ultimately victorious policy of patient containment of the USSR until, after many decades, that mad fever broke, for which he deserves at least as much credit as Ronald Reagan.)

    Nevertheless, if you still doubt that counter-mercantilism also had an altruistic component, remember this -- that the new, unprecedented trade regime was instituted by the author of the renowned Marshall Plan — both a name and an endeavor that still ring in human memory as synonymous with using power for generosity and good. Is it therefore plausible that Marshall -- along with Dean Acheson, Truman and Eisenhower -- might have known exactly what export-driven development would accomplish for the peoples of Europe, Asia, and so on?

    Cynics might doubt that anyone could ever look that far and that sagely ahead. But I am both an optimist and a science fiction author. I find it entirely plausible.

    Alas No One Seems to Notice

    Unfortunately, while recipients of the Marshall Plan's direct aid could clearly see beneficial results, right away, other parts of the program -- especially counter-mercantilist trade policy -- were slower in showing their effects, though they were far more vast and important, over the log run.

    What they amounted to was nothing less than the greatest unsung aid-and-uplift program in human history. A prodigious transfer of wealth and development from the United States to one zone after another, where cheap labor transformed, often within a single generation, into skilled and educated worker-citizens of a technologized nation. A program that consisted of Americans buying continental loads of things they did not really need. Things that they could easily done without and stopped buying, any time that they, or their leaders, chose to call a halt.

    (Oh, sure, the U.S would sometimes make a stink and nibble away at the edges of these unfair trade flows. But such efforts were never serious, intense, or undertaken with anything like full power or national will behind them. No plausible theory was ever raised, to explain that tepidness... until now.)

    Yes, yes. There are a few obvious cavils to this blithe picture. One might ask -- does anyone deserve "moral credit" for this huge and staggeringly successful "aid program"?

    Well, that is a good question. Perhaps not the American consumers, who made all this happen by embarking on a reckless holiday, acting like wastrels, saving nothing and spending themselves deep into debt. Certainly, even at best, this wealth transfer seems less ethically pure or pristinely generous than other, more direct forms of aid.

    Moreover, as the author of a book called Earth, I’d be remiss not to mention that all of this consumption-driven growth came about at considerable cost to our planet. For all our sakes, the process of ending human poverty and creating an all-encompassing global middle class needs to get a lot more efficient, as soon as possible. Call it another form a debt that had better be repaid, or else.

    Nevertheless, if credit is being given to the Japanese, "for inventing this export-oriented development model," then I think it is time for some historical perspective. Because the impression that one gets from many, especially in the East, is that the West must forever remain counter-mercantilist as if by some law of nature, and that the vigorously pro-mercantilist policies of the East are some kind of inherently perpetual birthright. Or else, these trade patterns are purely the result of asiatic cleverness, outwitting those decadent Americans in some kind of great game

    This view of the present situation may feel satisfying, but it is wholly inaccurate. Moreover, it could lead to serious error, in years to come... as it did across centuries past.

    What Might The Future Bring?

    Even if America is exhausted, worn out and a shadow of her former self, from having spent her way from world dominance into a chasm of debt, the U.S. does have something to show for it the last six decades.

    A world saved. A majority of human beings lifted out of poverty. That task, far more prodigious than defeating fascism and communism or going to the moon, ought to be viewed with a little respect. And I suspect it will be, by future generations.

    This should be contemplated, soberly, as other nations start to consider their time ahead as one of potential triumph. As they start to contemplate the possibility of becoming the next great pax or "central kingdom."

    If that happens -- (as I portray in a coming novel) -- will they emulate Marshall and Truman, by starting their bright era of world leadership with acts of thoughtful and truly farsighted wisdom? Perhaps even a little gratitude? Or at least by evading the mistakes that are written plain, across the pages of history, wherever countries briefly puffed and preened over their own importance, imagining that this must last forever?

    Is Anybody Still Reading

    Probably not. This unconventional assertion will meet vigorous resistance, no matter how clearly it is supported by the historical record. The reflex of America-bashing is too heavily ingrained, within the left and across much of the world, for anyone to actually read the ancient annals and realize that the United States is undoubtedly the least hated empire of all time. If its "pax" is drawing to a close, it will enter retirement with more earned goodwill than any other. Perhaps even enough to win forgiveness for the inevitable litany of imperial crimes.

    But no, even so, the habit is too strong. My attempt to bring perspective will be dismissed as arrogant, jingoist, hyper-patriotic American triumphalism. That is, if anybody is still reading, at all.

    Meanwhile, on the American right, we do have genuine triumphalists of the most shrill and stubborn type -- mostly moronic neocons -- who share my appreciation for Pax Americana... but for all the wrong reasons, and without even a scintilla of historical wisdom. Indeed, it is as if we are using the same phrase to stanf for entirely different things. If they are still reading, I can only point out that their era of misrule deeply harmed the very thing they claim to love.

    Alas, my aim does not fit into stereotypical agendas of either left or right. Instead, I am simply pointing out the necessary sequence of causation events that had to occur, in order for the International Miracle of export-driven development, of the last sixty years, to have taken place at all. Indeed, it is the fervent, tendentious and determined denial, that American policy played any role at all, that beggars the imagination.

    And so, at risk of belaboring the point, let me reiterate. If the U.S. had done the normal thing, the natural human thing, and imposed mercantilist trade patterns after WWII -- as every single previous "chung kuo" empire ever did before it -- then the U.S. would have no debt today. Our factories would be humming and the country would be swimming in gold...

    ...but the amount of hope and prosperity in the world would be far less, ruined by the same self-centered, short-sighted greed that eventually brought down empires in Babylon, Persia, Rome, China, Britain and so on.

    Also, by this point, every American youth would be serving in armies of occupation, and the entire world would by now be simmering and plotting for the downfall of the Evil Empire. That is the way the old pattern was written. But it is not how this "pax" was run. Instead, the greater part of the world was saved from poverty by the same force that rescued it from the fascistic imperialism and communism.

    Yes, America's era of uplifting the globe by propelling the world's export-driven growth must be over. Having performed this immense task, Americans cannot expect (if Wu Jianmin is any example) any credit or thanks.

    But that is okay. Nobody needs to be angry and we certainly do not have to be thanked. It simply is done. Other dire problems now stand waiting for this much richer world to address them. And meanwhile, the U.S. must rebuild.

    In other words, soon it will be time for someone else to start buying, for a change. The products, the services, and especially the ideas -- of which we will always have plenty.

    New ideas, for a new century, when efficient production and care for the planet will combine with far-sighted mindfulness of generations to come. Ideas that – just like George Marshall’s – the world will need and want.

    And just watch. America will be happy to sell.

    Deus Sex Machina

    [Linda MacDonald Glenn is guest blogging this month] (cross-posted on the Women's Bioethics Blog)

    (Roughly translated from Latin as Sex God in the machine) We all know that technology can improve our lives (sometimes....well, at least when it's working properly), but who'd have thunk that nanotechnology could improve your sex life?

    In yet one more 'tool' in the arsenal against dreaded erectile dysfunction, nanotechnology to the rescue! Scientists at Albert Einstein College of Medicine of Yeshiva University have developed a foam with nanoparticles encapsulating nitric oxide for the topical treatment of erectile dysfunction (ED). Why is topical better? Because ED medications such as sildenafil , vardenafil, and tadalafil have limitations -- they can cause systemic side effects such as headache, facial flushing, nasal congestion, upset stomach, and abnormal vision. Might this have implications for Female Arousal Disorder for which there remains little, if any, treatment? One can only hope....perhaps the announcement of the new 'female viagra' for pre-menopausal women can benefit from this new delivery system.

    On balance, though, Blue Cross Biomedical has developed a new foam condom for use by women, that looks like a vaginal inhaler. The Blue Cross Foam Condom uses a “formulated condom concentrate” comprised of nano silver particles as well as 'surfactant octyl phenoxy -RH4,tween-20, sapn-60,polyethylene glycol 400, deionized water'. Perhaps a male contraceptive can be advanced utilizing a nano-delivery system?

    My humble request to scientists and researchers: Equal time for both sexes, please!

    IBM’s claim to have simulated a cat’s brain grossly overstated

    Blue Gene
    This is not a brain.


    I'm a big fan of IBM's Brain and Mind Institute (BMI) and the Blue Brain project. Initiated in May 2005, the Blue Brain project is an attempt to to model the mammalian cerebral cortex with computers. The intention is not to re-create the actual physical structure of the brain, but to simulate it using arrays of supercomputers. Ultimately, the developers are hoping to create biologically realistic models of neurons. In fact, the results of the simulation will be experimentally tested against biological columns.

    But I take exception to the recent claim that IBM has created a simulation that is supposedly on par, in terms of complexity and scale, with an actual cat's brain. The media tends to sensationalize these sorts of achievements, and in this case, grossly overstate (and even misstate) the actual accomplishment.

    Contrary to what some people may believe, IBM has not created a virtual cat. There's no simulated cat somewhere pouncing around simulated fields chasing simulated mice inside a supercomputer. All IBM has done is replicate the power of a cat's cebebral coretex using a bunch of powerful computers. Nothing more -- there's no psychological or AI element involved whatsoever. They're merely creating a physical power structure and computational infrastructure that may someday run a properly engineered mind.

    But credit where credit is due.

    IBM has made incredible progress in the sophistication and detail level of human brain mapping. By reverse engineering the human brain, IBM hopes to bring about the era of "cognitive computing," -- a development that would bring about new ways for building computers which mimic natural brain structures.

    Essentially, IBM is hoping to simulate a neocortical column, which is the smallest functional unit of the neocortex. This is the part of the brain that is responsible for higher functions such as conscious thought. In humans, the neocortical column is 2mm tall, has a diameter of 0.5mm and contains 60,000 neurons. Project developers initially worked to replicate the neocortical column of a rat, which has only 10,000 neurons, and now they've achieved the same thing with the cat brain. Developers hope to model the human brain in about seven to eight years.

    To model these components the developers use a Blue Gene supercomputer that runs the MPI-based 'Neocortical Simulator' combined with 'NEURON' software. Blue Gene is a computer architecture project that has will spawn several next-generation supercomputers -- computers that will reach operating speeds in the petaflops range, and are currently reaching speeds over 280 sustained teraflops. Its 8,000 processors will crunch away at 23 trillion operations per second.

    I don't want to take away from IBM's accomplishment, but it's important to note that we are extremely far off in terms of our ability to emulate the true complexity of a mammalian brain. Creating an array of supercomputers that mimics the brute force of a biological brain and then claiming that it matches the 'complexity' and 'scale' of the real thing is pure hyperbole. True whole brain emulation (PDF) is still a far ways off.

    Call 1-800-New-Organ, by 2020?

    [Linda MacDonald Glenn is guest blogging this month]

    Growing a set of new teeth, or new kidneys, or new eyes, or whatever it is you need, is something we could do as soon as 2020, according to a report that was issued by the Department of Health and Human Services a few years ago. In a follow-up to George's previous post, I'll be following and reporting on issues in regenerative medicine, with a focus on nano-scale materials and technology. The NIH uses the term 'regenerative medicine' interchangeably with 'tissue engineering' and defines it as "a rapidly growing multidisciplinary field involving the life, physical and engineering sciences that seeks to develop functional cell, tissue, and organ substitutes to repair, replace or enhance biological function that has been lost due to congenital abnormalities, injury, disease, or aging.” And researchers are doing amazing things: Gizmodo has posted videos from Wake Forest Institute for Regenerative Medicine, about how lab grown tissues are benefiting patients now.

    Regenerative nanomedicine will, understandably, likely be embraced for all the promise it holds -- but there have been concerns expressed about the ethical, legal, and social implications, particularity the nano part. Nanotechnology has the potential to have the greatest impact in three areas: energy, medicine, and environmental remediation. Of these three areas, nanotechnology in medicine is the most likely to be accepted by the public, starting with therapeutic treatments and then moving over to enhancements. But it does raise some interesting questions, such as can nanomedicine be considered separate and apart other nanotechnologies? And what does 'nanotechnology' encompass anyway? Pinning down a usable definition of nanotechnology has been harder than anticipated.

    For a quick peek into some of the issues, you can check out the series of YouTube videos my colleague and I did at the Human Enhancement Conference in Kalamazoo earlier this year, which I'm hoping to post on Vimeo shortly. I'm also following Gizmodo's feature This Cyborg Life and am intrigued by the question, what is the enhancement that you would like to have the most? (and keep it decent, folks, comments are moderated here!) For the readers of Sentient Developments, I'll tell you mine, if you tell me yours....

    Let’s get metaphysical: How our ongoing existence could appear increasingly absurd

    So the Large Hadron Collider has been shut down yet again – this time on account of a bird dropping a piece of a bagel onto some sensitive outdoor machinery. The incident is not expected to keep the LHC out of commission for too much longer, but it represents yet another strange event that has kept the world’s most infamous particle accelerator out of service. In fact, the LHC has yet to function at full operational capacity since its completion over a year ago.

    What makes this all the more interesting is that the Hadron Collider has been dubbed by some observers as a doomsday device on account of its unprecedented size and power. A minority of scientists and philosophers believe that the collider could produce a tiny black hole or a strangelet that would convert Earth to a shrunken mass of strange matter.

    It's worth re-stating, however, that this is a fringe opinion. Several years ago, Max Tegmark and Nick Bostrom wrote a piece for Nature in which they concluded that a civilization destroys itself by a particle accelerator experiment once every billion years.

    Okay, admittedly, one in a billion seems excruciatingly improbable. But not impossible. And it's this 'shadow of doubt' that has got so many people in a tizzy -- especially when considering that this so-called doomsday machine keeps breaking down. Seems awfully convenient, doesn't it? Are we to believe that this is mere co-incidence? Or is there something more to what's going on?

    Now, I'm not talking about conspiracies or sabotage, here. Rather, a number of philosophers are making the case that something more metaphysical is going on.

    Take, for example, the quantum immortality theory, which argues that you as an observer cannot observe your non-existence, so you will keep on observing your ongoing existence -- no matter how absurd. Aside from a large grain of salt, you also have to buy into the Everett Many Worlds interpretation of quantum mechanics for this to work. As the universe splinters into probability trees, there are new trajectories that are forced into existence by your ongoing presence; in an infinite universe all observations must be made, no matter how improbable.

    Now, at any given time we have to assume that we are living in the most probable of all possible habitable worlds. But that doesn't mean it's true -- it's just an assumption given the absence of sampling data. As quantum probability trees diverge, those that tread into more improbable spaces will begin to splinter with less and less frequency and diversity; there will be a limited number of escape routes given absurd and highly complex (but survivable) existence spaces.

    All this can lead to some rather bizarre conclusions -- including the thought experiment in which you attempt to obliterate yourself with an atom bomb, only to have some kind of force majeure get in the way that prevents you from acting on your suicide.

    It's important to remember that this only works for your ongoing existence. The rest of the world can burn around you; what matters is that you continue to observe the universe.

    Okay, back to Hadron. Let's assume for a moment that quantum immortality is in effect and that the LHC is in fact the apocalypt-o-matic. It can therefore be argued that, because we are all collectively put into peril by this thing, we will never get to observe it working properly. There will always be something that prevents the device from doing what it's supposed to be doing -- everything from mechanical failures through to birds dropping bagels on it.

    What's even more disturbing, however, is that these interventions could get increasingly absurd and improbable. It may eventually get to the point where we have to sit back and question the rationality of our existence. The world may get progressively screwed up and surreal in order for our personal existence to continue into the future.

    One could already make the case that our collective existence is already absurd on account of our possession of apocalyptic weapons, namely the nuclear bomb. We've already come alarmingly close to apocalypse, including the Cuban Missile Crisis and the infamous Stanislav Petrov incident. Would it be unfair of me to suggest that we should probably have destroyed ourselves by now? I would argue that the most probable of Everett Many World Earths have destroyed themselves through nuclear armageddon, but we happen to observe a version of Earth that has not.

    This said, our ongoing existence does not seem ridiculously absurd. There are rational and believable reasons that account for our ongoing existence, namely self-preservation and a rigid safety-check system that has prevented a nuclear accident from happening.

    But will the same thing be said a few years from now if the Hadron Collider keeps shutting down? What will happen to our sense of reality if stranger and stranger things start to intervene?

    And what about the more distant future when we have even more apocalyptic devices, including molecular assembling nanotechnology and advanced biotechnologies (not to mention artificial superintelligence)? It's been said that we are unlikely to survive the 21st Century on account of these pending technologies. But given that there are some probability trees that require our ongoing existence, what kind of future modes will that entail? Will it make sense, or will the succession of improbably survivable events result in a completely surreal existence? Or will our ongoing presence seem rational in the face of a radically altered existence mode -- like totalitarian repression or the onset of an all-controlling artificial superintelligence?

    Hopefully I don't need to remind my readers that this is pure philosophical speculation. Metaphysics is often fun (or disturbing as in this case), but it is no substitute for science. I think we should think about these possibilities, but not to the point where it impacts on our daily life and sense of reality.

    But I'm sure we'll all want to keep a close eye on that rather interesting particle accelerator in Switzerland.

    Creative thinking lets you believe whatever you want

    I thought I'd illustrate an important lesson with a link to a page called "the biblical evidence against evolution". It has some perfect examples of a lack of critical thinking ability, and demonstrates that humans are capable of using their own smartness against themselves. It also contains what I can probably only describe as the single most concentrated example of dark-side epistemology I have ever seen:

    What About All of the Scientific Evidence?


    If you still are not ready to put your complete faith and trust in God when it comes to science vs. Creation, it is probably because you are thinking some of these types of thoughts:

    "But what about the scientific evidence for the Big Bang (or the string theory, etc.) and the age of the universe? What about the fossil record and all of the scientific data that seems to be perfectly logical and seems to refute the Biblical account of Creation? What about the proven examples of evolution that are happening today? I can't just disregard all of the scientific facts that I have always been taught!"

    When it comes to science, keep in mind that there are many scientists who believe in the Big Bang theory and the theory of evolution, but there are many other scientists who believe that the scientific evidence proves the Creation account in the Bible. Therefore, it all boils down to which set of scientists you choose to believe! It still comes down to a question of faith. For example, Dr. Kent Hovind has a website in which he says, "I have a standing offer of $250,000 to anyone who can give any empirical evidence (scientific proof) for evolution. My $250,000 offer demonstrates that the hypothesis of evolution is nothing more than a religious belief" (see http://www.drdino.com/Ministry/250k/index.jsp Offsite Link). In over a decade, no-one has ever claimed the money. So the all-important question is whether our faith rests on the word of the non-Christian scientists, or whether our faith rests totally on God.

    Now, don't get me wrong, I realize that some "evolutionary" and "Big Bang" scientists are Christians. Still, that doesn't change the fact that the Big Bang (or other scientific "origins" theories) and evolution are the only answers which the non-Christian scientists have, and when there is a conflict between what they say and what God says, I'll stand with God every time. Actually, I have studied the evidence for the Big Bang, the age of the universe, the theory of evolution, etc., and some of it sounds fairly convincing to my logical mind. I enjoy science, and I recognize that there can be changing varieties within the different kinds of plants, animals, and other organisms (which is why we have "superbugs" that are resistant to antibiotics, for example). However, this ongoing process that we see happening in the world around us is called "microevolution" by scientists, and it is defined as "the gradual accumulation of mutations leading to new varieties within a species" (Webster's American Family Dictionary). It is not macroevolution, which is defined as a "major evolutionary change of species" (Webster's American Family Dictionary). The examples of microevolution that we can demonstrate in the world around us do not prove the theory of evolution, as any scientist will tell you. I would be perfectly happy to believe that we humans were formed through evolution if that view agreed with the overwhelming testimony of Scripture. But it doesn't. The internal testimony throughout the entire Bible is completely consistent and is completely in opposition to man's scientific theories about the Big Bang and evolution and so on. Therefore, I choose to believe God's Word no matter how convincing some of the scientific evidence might be. God is always right!

    If you really want to believe something, you can always find a way, no matter how strong or overwhelming the evidence against it is. There's always that one rogue scientist, that one possible argument in favor of your position (which stands up to scrutiny as long as you don't actually try to attack it at its weakest point).

    Yudkowsky on "Value is fragile"

    If I had to pick a single statement that relies on more Overcoming Bias content I've written than any other, that statement would be:

    Any Future not shaped by a goal system with detailed reliable inheritance from human morals and metamorals, will contain almost nothing of worth.

    If you believe this statement, there is cause to be very worried about the future of humanity. Currently, the future gets its detailed, reliable inheritance from human morals and metamorals because your children will have almost exactly the same kind of brain that you do, and (to a lesser extent) because they will be immersed in a culture that is (in the grand scheme of things) extremely similar to the culture we have today. Over many generations and technological changes, the inheritance of values between human generations breaks to some small extent, though it seems to the author that human hunter-gatherers from the very distant past want roughly the same things that modern humans do; they would be relatively at home in a utopia that we designed. That is a chain of reliable inheritance of values that spans fifty thousand years, from mother to daughter and father to son.

    When intelligence passes to another medium, it seems that the "default" outcome is the breaking of that chain, as Frank puts it:

    Each aspiration and hope in a human heart, every dream you’ve ever had, stopped in its tracks by a towering, boring, grey slate wall.

    How would it happen? Those who lusted after power and money would unleash the next version of intelligence, probably in competition with other groups. They would engage in wishful thinking, understate the risks, they would push each other forward in a race to be first. Perhaps the race might involve human intelligence enhancement or human uploads. The end result could be systems that have more effective ways of modeling and influencing the world than ordinary humans do. These systems might work by attempting to shape the universe in some way; if they did, they would shape it to not include humans, unless very carefully specified. But humans do not have a good track record of achieving some task perfectly the first time around under conditions of pressure and competition.

    To answer a few critics on Facebook: Stefan Pernar writes:

    The argument in the linked post goes something like this: a) higher intelligence = b) more power = c) we will be crushed. The jump from b) -> c) is a bare assertion.

    This post does not claim that any highly intelligent, powerful AI will crush us. It implicitly claims (amongst other things) that any highly intelligent, powerful AI whose goal system does not contain "detailed reliable inheritance from human morals and metamorals" will effectively delete us from reality. The justification for this statement is eluded to in the value is fragile post. As Yudkowsky states in that post, the set of arguments for this statement and counterarguments against it and counter-counterarguments constitutes a large amount of written material, much of which ought to appear on the Less Wrong wiki, but most of which is currently buried in the Less Wrong posts of Eliezer Yudkowsky.

    The most important concepts seem to be listed as Major Sequences on the LW wiki. In particular, the Fun theory sequence, the Metaethics sequence, and the How to actually change your mind sequence.
