Alex Wright: Glut: Mastering Information Though the Ages
### A Series of Information Explosions
As usual, microbes led the way. Bacteria have swarmed in intense networks for 3.5 billion years. Then a hierarchical form emerged with the first nucleated cells that were made up of an enclosed society of formerly independent organisms.
That's the pattern for the evolution of information, Alex Wright said. Networks coalesce into hierarchies, which then form a new level of networks, which coalesce again, and so on. Thus an unending series of information explosions is finessed.
In humans, classification schemes emerged everywhere, defining how things are connected in larger contexts. Researchers into "folk taxonomies" have found that all cultures universally describe things they care about in hierarchical layers, and those hierarchies are usually five layers deep.
Family tree hierarchies were accorded to the gods, who were human-like personalities but also represented various natural forces.
Starting 30,000 years ago the "ice age information explosion" brought the transition to collaborative big game hunting, cave paintings, and elaborate decorative jewelry that carried status information. It was the beginning of information's "release from social proximity."
5,000 years ago in Sumer, accountants began the process toward writing, beginning with numbers, then labels and lists, which enabled bureaucracy. Scribes were just below kings in prestige. Finally came written narratives such as Gilgamesh.
The move from oral culture to literate culture is profound. Oral is additive, aggregative, participatory, and situational, where literate is subordinate, analytic, objective, and abstract. (One phenomenon of current Net culture is re-emergence of oral forms in email, twittering, YouTube, etc.)
Wright honored the sequence of information-ordering visionaries who brought us to our present state. In 1883 Charles Cutter devised a classification scheme that led in part to the Library of Congress system and devised an apparatus of keyboard and wires that would fetch the desired book. H.G. Wells proposed a "world brain" of data and imagined that it would one day wake up. Teilhard de Chardin anticipated an "etherization of human consciousness" into a global noosphere.
The greatest unknown revolutionary was the Belgian Paul Otlet. In 1895 he set about freeing the information in books from their bindings. He built a universal decimal classification and then figured out how that organized data could be explored, via "links" and a "web." In 1910 Otlet created a "radiated library" called the Mundameum in Brussels that managed search queries in a massive way
until the Nazis destroyed the service. Alex Wright showed an [astonishing video of how Otlet's distributed telephone-plus-screen system worked](https://youtube.com/watch?v=qwRN5m64I7Y).
Wright concluded with the contributions of Vannevar Bush ("associative trails" in his Memex system), Eugene Garfield's Science Citation Index, the predecessor of page ranking. Doug Engelbart's working hypertext system in the "mother of all demos." And Ted Nelson who helped inspire Engelbart and Berners-Lee and who Wright considers "directly responsible for the generation of the World Wide Web."

Francis Fukuyama: 'The End of History' Revisited
### Democracy versus Culture
Francis Fukuyama began by describing the four most significant challenges to the thesis in his famed 1992 book,_[The End of History and the Last Man](http://www.amazon.com/End-History-Last-Man/dp/0743284550/ref=pd_bbs_sr_1/104-4300234-8355129?ie=UTF8&s=books&qid=1183410555/lono0a-20)_. In the book he proposed that humanity's economic progress over the past 10,000 years was driven by the accumulation of science and technology over time. That connection is direct and reliable.
Less direct and reliable, but very important, is the sequence from economic progress to the adoption of liberal democracy. Political modernization accompanies economic modernization. This is a deep force of history, the book claims.
Fukuyama describes the rise of the idea of human rights in the West as a secularization of Christian doctrine. That led to accountability mechanisms-- "You can't have good governance without feedback loops." Once there is a propertied middle class, they demand political participation. The threshold for that demand appears to about $6,000 per capita per year. It's hard to get to, but hundreds of millions of people in the world are making that climb right now.
China and Russia will be a test of his thesis, Fukuyama said. They are getting wealthier. If they democratize in the next twenty years, he's right. If they remain authoritarian, he's wrong.
Fukuyama is most intrigued by a challenge that comes from his old teacher and continuing friend, Samuel Huntington, author of _The Clash of Civilizations_. Culture can trump modernization, says Huntington-- current radical Islam is an example. Fukuyama agrees that people at the fringe of modernization feel a sense of onslaught, and they can respond as Bolsheviks and Fascists did in the 20th century. "A Hitler or a Bin Laden proclaims, 'I can tell you who you are.'"
A second challenge to the universalism of liberal democracy is that it does not yet work internationally. Fukuyama agrees, noting that the major current obstacle is America's overwhelming hegemony. He expects no solution from the UN, but an overlapping set of international institutions could eventually do the job.
A third challenge is the continuing poverty trap for so many in the world. Fukuyama says it takes a national state with the rule of law and time to learn from mistakes before you get economic takeoff. He sees later colonialism, done on the cheap (instead of with the patient institution building that England did in India), as a major source of the world's current failed and crippled states.
The final challenge that impresses Fukuyama is the possibility that technology may now be accelerating too fast to cure its own problems the way it has done in the past. Climate change could be an example of that. And Fukuyama particularly worries that biotechnology might so transform human nature that it will fragment humanity irreparably.
While he sees meaning in history, Fukuyama said it's not a matter of iron law. Human agency counts. History swerves on who wins a battle or an election. We are responsible.
Two further angles on Fukuyama's thesis emerged at dinner. One concerned how society's morality should express itself in dealing with the threat/promise of biotechnology. Conservative Fukuyama promoted strict government regulation while the liberals (and libertarians) in the room said the market and Internet should sort it out. Kevin Kelly asked Fukuyama, "Do you think human nature is as good as it can be?" I proposed to Washington-based Fukuyama that he was in the midst of a classic argument between the coasts. East Coast says, "Ready, aim, don't fire." West Coast says, "Fire, aim, ready."
Then there's the European Union. In his talk Fukuyama praised it as the fullest realization of his theory. At dinner he acknowledged his concern that Europe may be headed toward permanent conflict with its growing immigrant populations, whose first allegiance continues to be to their own cultures.

Paul Hawken: The New Great Transformation
### Humanity's immune system
The title of Paul Hawken's talk, "The New Great Transformation," has two referents, he explained. Economist Karl Polanyi's 1944 book, _The Great Transformation_ , said that the "market society" and modern nation state emerged together in Europe after 1700 and divided society in ways that have yet to be healed.
Karen Armstrong's 2006 book, _The Great Transformation_ , explores "the Axial Age" between 800 and 200 BC when the world's great religions and philosophies first took shape. They were all initially social movements, she says, acting on revulsion against the violence and injustice of their times.
Both books describe conditions in which "the future is stolen and sold to the present," said Hawken-- a situation we are having to deal with yet again.
His new book, [_Blessed Unrest_](http://www.amazon.com/Blessed-Unrest-Largest-Movement-Coming/dp/0670038520/lono0a-20), was inspired by the countless business cards that earnest environmentalists would hand him after his lectures all over the world. After a while he had 7,000, and he wondered, "How many environmental groups are there in the world?" He began actively building a now-public database, [WiserEarth.org](http://www.wiserearth.org/), which includes social justice and indigenous rights organizations because he found they indivisibly overlap in their values and activities.
The database now has 105,000 such organizations. The still-emerging taxonomy of their "areas of focus" has 414 categories, amounting to a "curriculum of the 21st century"-- Acid Rain, Living Wages, Tropical Moist Forests, Peacemaking, Democratic Reform, Sustainable Cities, Environmental Toxicology, Watershed Management, Human Trafficking, Mountaintop Removal, Pesticides, Climate Change, Refugees, Women's Safety, Eco-villages, Fair Trade… Extrapolating from carefully inventoried regions to those yet to be tallied, he estimates there are over 1,000,000 such organizations in the world, adding up to the largest and fastest growing Movement in history.
The phenomenon has been overlooked because it lacks the customary hallmarks of a movement-- no charismatic leaders, no grand theory or ideology, no "ism," no defining events. The new activist groups are about dispersing power rather than aggregating power. Their focus is on ideas rather than ideology-- ideologies are clung to, but ideas can be tried and tossed or improved. The point is to solve problems, usually from the bottom up. The movement can never be divided because it is already atomized.
What's going on? Hawken wondered if humanity might have some collective intelligence that we don't yet understand. The metaphor he finds most useful is the immune system, which is the most complex system in our body-- more complex than the entire Internet-- massive, distributed, subtle, ingenious, and effective. The opposite of a hierarchical army, its power is in the density of its network. It deals with problems not through frontal attack but complex negotiation and rapprochement.
Much of the new movement, Hawken said, was inspired, at root, by the slavery abolitionists and by the Transcendentalists Emerson and his student Thoreau. Emerson declared that "everything is connected," and Thoreau wound up going to jail (and making it cool) by taking that idea seriously in social-justice terms.
Now, as in the Axial Age, activism comes from acting on the realization that "all life is sacred."

Steven Johnson: The Long Zoom
### Consilience defeats miasma
Steven Johnson began his long zoom survey with the "prior art" of Joyce's Stephen Daedalus locating himself in himself, his neighborhood, Dublin, on out to the universe. The value of a long zoom is in identifying and employing every scale between the very large and very small, noticing how they change each other when held in the mind at the same time.
Johnson's core story (and current book) concerned London in 1854, when it was the largest city in the world and in history with 2.5 million people. London famously stank. Cesspools filled basements, slaughterhouses were anywhere, garbage piled up.
Medicine at the time held that disease was caused by "miasma," foul air, noxious vapors. "All smell is disease," declared a Doctor Chadwick. The authorities decided that the way to cure the frequent cholera epidemics in London was to get rid of the bad odor-- pump the sewage into the Thames, which people drank. The cholera got worse.
Johnson's goal with his book, [_The Ghost Map_](http://www.amazon.com/Ghost-Map-Steven-Johnson/dp/1594489254/ref=pd_bbs_sr_1/102-6115062-9930528?ie=UTF8&s=books&qid=1179248667/lono0a-20), was to figure out why the wrong theory of disease lingered so long, and what it took to correct it. The answer, he proposes, is in the perspective of the long zoom.
The celebrated story goes that John Snow discovered the polluted-water cause of cholera by drawing a "ghost map" of the cholera deaths concentrated around the Broad Street pump in Soho. What really happened is more interesting. Snow had been publishing his theory of water pollution causing cholera for five years. In August of 1854, a horrifying 10% of his neighborhood in Soho perished from the disease. Then he drew up the map, drawing on public statistics provided by the city, and on the street savvy of a popular vicar named Rev. Henry Whitehead.
The map confirmed his theory and persuaded the medical establishment and city authorities. In just 12 years, cholera was completely eradicated from London.
In Johnson's view, one long zoom had displaced another. The miasma theory of cholera embraced a nested set of scales ranging, from large to small:_cultural traditions - urban development - technology - contemporary politics - "great men" \- human sensory system_. Bad smell, bad people, bad disease.
With John Snow's map, a different long zoom took over:_cities - data systems - neighborhood - humans - organs - microbes_. The combination of city density and open-source data about the epidemic made the ghost map possible and persuasive. Doctor Snow noticed that the bodily symptoms of cholera looked like they were caused by something swallowed rather than something inhaled. The data had to be extremely strong to overcome the bias of human sensory apparatus-- our alarm system of smell can detect minute amounts of contagion, but we cannot see them. It took a neighborhood map to defeat what the nose thought it knew.
Johnson proposed that another word for the long zoom perspective is "consilience"-- a fine old word, revived by Edward O. Wilson, that links multiple disciplines and multiple levels into a whole body of knowledge with extra benefits the separate disciplines lack. Science and culture can blend rigorously. What is discovered in consilience is not just scales of distance or time but nested systems.
Johnson moved on to contemporary popular culture, drawing on his research for his brain book ([_Emergence_](http://www.amazon.com/Emergence-Connected-Brains-Cities-Software/dp/0684868768/ref=sr_1_3/102-6115062-9930528?ie=UTF8&s=books&qid=1179248720/lono0a-20)) and his book on video games and TV ([_Everything Bad Is Good For You_](http://www.amazon.com/Everything-Bad-Good-Steven-Johnson/dp/B000O17CYM/ref=sr_1_2/102-6115062-9930528?ie=UTF8&s=books&qid=1179248720/lono0a-20)). Back in the three-network days of "Gilligan's Island," the guiding principle was "least objectionable programming." Now with DVDs and TiVo, the guideline is "most repeatable programming"-- material that will reward you if you study it again and again. Thus a current hit TV series about a very different island, "Lost," has a whole horde of characters and purveys many-leveled complexities and mysteries embracing _geography - economics - technology - sociology - biology - ontology_. Viewers are invited to wonder, among a great many other things, whether the whole damn thing is a dream, and, if so, whose?
Our brain is wired with "seeking circuitry" and relishes exercising "the regime of competence." TV shows like "Lost" and video games like "World of Warcraft" are addictive because they reward exploration. Instead of employing narrative arcs, they keep you in a state of being always challenged but not quite overwhelmed as you ascend from skill level to skill level.
We are learning to master complexity, to revel in long zooms like Google Earth or the forthcoming Will Wright game, "Spore." A few years ago, Johnson was introducing his 7-year-old nephew to Wright's early video game, "Sim City"-- "Ooh, look at the big buildings!" Shortly, Johnson's factory district was failing. His nephew piped up. "Lower your industrial tax rate," said the child.
Johnson ended the talk with another line from James Joyce: "It was very big to think about everything and everywhere."
"It's never been easier," said Johnson.
PS… Also announced at this talk is the [North American Premiere of Brian Eno's 77 Million Paintings](https://longnow.org/77m/).

Frans Lanting: Life's Journey Through Time
### The deep past in the remote present
It began on a New Jersey beach. Frans Lanting was photographing horseshoe crabs for a story about how they are being ground up for eel bait and at the same time their blood is used for drug testing--a $100 million industry. The crabs have primordial eyesight, which they employ mainly for finding sex partners. Photographing the horseshoes having a spawning orgy one spooky twilight, Lanting felt like he was suddenly back in the Silurian, 430 million years ago…
So Lanting and his wife Chris Eckstrom set out in search of "time capsules," places on the present Earth where he could find and photograph all the ancient stages of life. A two-year project expanded to seven years.
On a live volcano in Hawaii he found the naked planet of 4.3 billion years ago-- molten rock flowing, zero life. "Your boots melt. You smell early Earth." On the western coast of Australia he shot a rare surviving living reef of stromatolites, made of the cyanobacteria that three billion years ago transformed the Earth by filling the atmosphere with oxygen. Lanting took pains to photograph without blue sky in the background, because the sky was not blue until the cyanobacteria had generated a planet's worth of oxygen.
Life's journey through time is a story of innovations, Lanting said. Lichens were the first to colonize land, followed by shelled creatures that could carry ocean inside them-- crabs, turtles, and snails. In Australia Lanting photographed mudskippers--amphibious fish that use their pectoral fins to crawl around on mud and even climb trees.
Dinosaurs once browsed on land plants that defended themselves with ferocious spiky leaves. A survivor of that battle is the Araucaria tree in Chile. Lanting planted one in his garden near Santa Cruz and photographed it there.
Study of the first feathered reptile, the archaeopteryx, suggested that the contemporary bird with the most similar flight style is the frigate bird, and Lanting photographed one looking like an airborne fossil in the Galapagos Islands.
Asteroids and climate change made new niches and new innovations. Following the Cretaceous extinction 65 million years ago, mammals deployed their toothed jaws. Drier climate 25 million years ago created grasslands. When the forests dried, some apes took to walking upright in the savannahs of Africa. And some of those got around to analyzing DNA and noticing that life's entire history is written there.
Lanting ended his dazzling show with two demonstrations. One was an 8-minute segment of an hour-long orchestral version of "Life's Journey Through Time," composed by Philip Glass, with a brilliant multi-media version of Lanting's photos. The music and the image dynamics gain complexity stage by stage in synch with the growing complexity of life. (It would be glorious to see this performed locally with the San Francisco Symphony. The ideal occasion would be the opening of the new California Academy of Sciences building in Golden Gate Park next year.)
Lanting also did a quick demo of the timeline version of his photos (and videos) on his website. The level of its sophistication drew cheers and applause from the Web-savvy San Francisco audience. See for yourself:
The take home version of this talk is Lanting's book, [_Life: A Journey Through Time_](http://www.amazon.com/Life-Journey-Through-Frans-Lanting/dp/3822839949/ref=pd_bbs_sr_1/104-8919416-0579929?ie=UTF8&s=books&qid=1177966282/lono0a-20), and is a stunning oversized edition published by Taschen.
P.S. Lanting's presentation in particular is worth seeing in high-quality video.

Brian Fagan: We Are Not the First to Suffer Through Climate Change
### Catastrophic drought is coming back
There are two kinds of historians, Brian Fagan says, parachutists and truffle hunters. Parachutists command an overview of the landscape, while truffle hunters dig deeply to uncover marvelous treasures. Fagan is a parachutist. In his talk Fagan emphasized a wide view of human history as it unrolls in the landscape of climate. In our lookout from the parachute, we can see evidence from ice cores, tree rings, fossil pollen, and historical records, all pointing to the conclusion that people in the past have suffered through global warming periods before. So what happened?
Using data from truffle-hunting historians, Fagan told of how vineyard harvest records in Europe show that England became so warm during the period between 800-1250 AD that England not only had vineyards in its central provinces but it also exported wine to France. The medieval warm period had repercussions throughout society. Iceland and Scandinavia warmed up enough to grow cereal crops, tree lines elevated in mountain areas, and there were longer growing seasons everywhere on the continent.
This warming up of agriculture initiated the first vast clear-cutting of European forests. In the short 200 years between 1100 and 1300, from one-third to one-half of European wooded wilderness was deforested to make way for fields and pastures -- shaping the lovely farm scenes we now associate with Europe. (Today only Poland has any remaining virgin forests).
Fagan says the myth of the medieval warm period is that it was warm. There were all kinds of weather extremes. In 1315 it started to rain for seven years. The newly cleared and naked hills eroded, dams burst, disease spread, and prolonged drought followed.
And not just in Europe. Mesoamerica was jolted by long droughts. The Mayan pyramids at Tikal were engineered to act as water collection reservoirs. The collapse of their empire, and others in South America such as the Inca in Peru, are correlated to prolonged droughts.
Indeed, says Fagan, the elephant in the climate room is drought. As recently as the 1800s, prolonged droughts killed 20-30 million people in India during the British Raj period. We have a tendency to believe that modern technology has alleviated our susceptibility to drought, and it has -- except for the billions of people on earth today who are living as subsistence farmers.
It is upon these people that Fagan wanted us to focus our attention and care, because it is upon these people that the most serious consequences of global warming will fall. Referring to his own experience of many years as an archeologist in Africa, he painted a vivid image of what a severe drought entails and how a drought can act like a cascading disruption and rapidly destroy a vibrant culture to the point where it disappears completely.
Forget the rocketing "hockey stick" of global warming, he urges. Even mild climate warming produces prolonged droughts, and we should expect more of them. There's already been a 25% increase in droughts globally since 1990. In the next 100 years, we can expect the number of people to be affected by droughts to rise from 3% of the world's population to 30%.
The lesson Fagan wanted us to leave with was that the effects of global warming will be felt greatest on marginal land and marginal peoples -- many far from the sea and rising sea levels - and that because of their marginality, the consequences of prolonged drought will not just be inconvenient, but devastating.
In the question and answer period, he was asked what the stricken people can do about it? "Move," he said, "is the only option." If the world is heating up, where would he move to? "Canada. It will be dryer, much warmer, and their politics are reasonable."

Vernor Vinge: What If the Singularity Does NOT Happen?
### Non-Singularity scenarios
Vinge began by declaring that he still believes that a Singularity event in the next few decades is the most likely outcome-- meaning that self-accelerating technologies will speed up to the point of so profound a transformation that the other side of it is unknowable. And this transformation will be driven by Artificial Intelligences (AIs) that, once they become self-educating and self-empowering, soar beyond human capacity with shocking suddenness.
He added that he is not convinced by the fears of some that the AIs would exterminate humanity. He thinks they would be wise enough to keep us around as a fallback and backup-- intelligences that can actually function without massive connectivity! (Later in the Q&A I asked him about the dangerous period when AI's are smart enough to exterminate us but not yet wise enough to keep us around. How long would that period be? "About four hours," said Vinge .)
Since a Singularity makes long-term thinking impractical, Vinge was faced with the problem of how to say anything useful in a Seminar About Long-term Thinking, so he came up with a plausible set of scenarios that would be Singularity-free. He noted that they all require that we achieve no faster-than-light space travel.
The overall non-Singularity condition he called "The Age of Failed Dreams." The main driver is that software simply continues failing to keep pace with hardware improvements. One after another, enormous billion-dollar software projects simply do not run, as has already happened at the FBI, air traffic control, IRS, and many others. Some large automation projects fail catastrophically, with planes running into each. So hardware development eventually lags, and materials research lags, and no strong AI develops.
To differentiate visually his three sub-scenarios, Vinge showed a graph ranging over the last 50,000 and next 50,000 years, with power (in maximum discrete sources) plotted against human populaton, on a log-log scale. Thus the curve begins at the lower left with human power of 0.3 kilowatts and under a hundred thousand population, curves up through steam engines with one megawatt of power and a billion population, up further to present plants generating 13 gigawatts.
His first scenario was a bleak one called "A Return to MADness." Driven by increasing environmental stress (that a Singularity might have cured), nations return to nuclear confrontation and policies of "Mutually Assured Destruction." One "bad afternoon," it all plays out, humanity blasts itself back to the Stone Age and then gradually dwindles to extinction.
His next scenario was a best-case alternative named "The Golden Age," where population stabilizes around 3 billion, and there is a peaceful ascent into "the long, good time." Humanity catches on that the magic ingredient is education, and engages the full plasticity of the human psyche, empowered by hope, information, and communication. A widespread enlightened populism predominates, with the kind of tolerance and wise self-interest we see embodied already in Wikipedia.
One policy imperative of this scenario would be a demand for research on "prolongevity"-- "Young old people are good for the future of humanity." Far from deadening progress, long-lived youthful old people would have a personal stake in the future reaching out for centuries, and would have personal perspective reaching back for centuries.
The final scenario, which Vinge thought the most probable, he called "The Wheel of Time." Catastrophes and recoveries of various amplitudes follow one another. Enduring heroes would be archaeologists and "software dumpster divers" who could recover lost tools and techniques.
What should we do about the vulnerabilities in these non-Singularity scenarios? Vinge 's main concern is that we are running only one, perilously narrow experiment on Earth. "The best hope for long-term survival is self-sufficient off-Earth settlements." We need a real space program focussed on bringing down the cost of getting mass into space, instead of "the gold-plated sham" of present-day NASA.
There is a common critique that there is no suitable place for humans elsewhere in the Solar System, and the stars are too far. "In the long now," Vinge observed, "the stars are not too far."
**(Note: Vinge's detailed notes for this talk, and the graphs, may be found online at:****[http://rohan.sdsu.edu/faculty/ vinge /longnow/index.htm](http://rohan.sdsu.edu/faculty/vinge/longnow/index.htm) ** **)**

Philip Tetlock: Why Foxes Are Better Forecasters Than Hedgehogs
### Ignore confident forecasters
"What is it about politics that makes people so dumb?"
From his perspective as a psychology researcher, Philip Tetlock watched political advisors on the left and the right make bizarre rationalizations about their wrong predictions at the time of the rise of Gorbachev in the 1980s and the eventual collapse of the Soviet Union. (Liberals were sure that Reagan was a dangerous idiot; conservatives were sure that the USSR was permanent.) The whole exercise struck Tetlock as what used to be called an "outcome-irrelevant learning structure." No feedback, no correction.
He observes the same thing is going on with expert opinion about the Iraq War. Instead of saying, "I evidently had the wrong theory," the experts declare, "It almost went my way," or "It was the right mistake to make under the circumstances," or "I'll be proved right later," or "The evilness of the enemy is still the main event here."
Tetlock's summary: "Partisans across the opinion spectrum are vulnerable to occasional bouts of ideologically induced insanity." He determined to figure out a way to keep score on expert political forecasts, even though it is a notoriously subjective domain (compared to, say, medical advice), and "there are no control groups in history."
So Tetlock took advantage of getting tenure to start a long-term research project now 18 years old to examine in detail the outcomes of expert political forecasts about international affairs. He studied the aggregate accuracy of 284 experts making 28,000 forecasts, looking for pattern in their comparative success rates. Most of the findings were negative-- conservatives did no better or worse than liberals; optimists did no better or worse than pessimists. Only one pattern emerged consistently.
"How you think matters more than what you think."
It's a matter of judgement style, first expressed by the ancient Greek warrior poet Archilochus: "The fox knows many things; the hedgehog one great thing." The idea was later expanded by essayist Isaiah Berlin. In Tetlock's interpretation, Hedgehogs have one grand theory (Marxist, Libertarian, whatever) which they are happy to extend into many domains, relishing its parsimony, and expressing their views with great confidence. Foxes, on the other hand are skeptical about grand theories, diffident in their forecasts, and ready to adjust their ideas based on actual events.
The aggregate success rate of Foxes is significantly greater, Tetlock found, especially in short-term forecasts. And Hedgehogs routinely fare worse than Foxes, especially in long-term forecasts. They even fare worse than normal attention-paying dilletantes -- apparently blinded by their extensive expertise and beautiful theory. Furthermore, Foxes win not only in the accuracy of their predictions but also the accuracy of the likelihood they assign to their predictions-- in this they are closer to the admirable discipline of weather forecasters.
The value of Hedgehogs is that they occasionally get right the farthest-out predictions-- civil war in Yugoslavia, Saddam's invasion of Kuwait, the collapse of the Internet Bubble. But that comes at the cost of a great many wrong far-out predictions-- Dow 36,000, global depression, nuclear attack by developing nations.
Hedgehogs annoy only their political opposition, while Foxes annoy across the political spectrum, in part because the smartest Foxes cherry-pick idea fragments from the whole array of Hedgehogs.
Bottom line… The political expert who bores you with an cloud of "howevers" is probably right about what's going to happen. The charismatic expert who exudes confidence and has a great story to tell is probably wrong.
And to improve the quality of your own predictions, keep brutally honest score. Enjoy being wrong, admitting to it and learning from it, as much as you enjoy being right.
(Iraq footnote. I asked Tetlock to opine on which experts were most right about how things have gone in the Iraq War. He said the most accurate in this case were the regional experts, who opposed the invasion, and what they are predicting now is a partition of Iraq into Kurdish, Shia, and Sunni areas.)

Philip Rosedale: 'Second Life:' What Do We Learn If We Digitize EVERYTHING?
### 2nd Life takes off
What is real life coming to owe digital life?
After a couple years in the flat part of exponential growth, the steep part is now arriving for the massive multi-player online world construction kit called "Second Life." With 1.7 million accounts, membership in "Second Life" is growing by 20,000 per day. The current doubling rate of "residents" is 7 months, still shortening, which means the growth is (for now) hyperexponential.
For this talk the founder and CEO of "Second Life," Philip Rosedale, tried something new for him-- a simultaneous demo and talk. His online avatar, "Philip Linden," was on the screen showing things while the in-theater Philip Rosedale was conjecturing about what it all means. "This is a game of 'Can I interest you more in what I'm saying than what's going on on the screen?'"
He showed how new arrivals go through the "gateway" experience of creating their own onscreen avatar, explaining that because intense creativity is so cheap, easy, and experimental, the online personas become strongly held. "You can have multiple avatars in 'Second Life,' but the overall average is 1.25 avatars per person." The median age of users is 31, and the oldest users spend the most time in the world (over 80 hours per week for 10 percent of the residents). Women are 43 percent of the customers.
The on-screen Philip Linden was carrying Rosedale's talk notes (handwritten, scanned, and draped onto a board in the digital world). Rosedale talked about the world while his avatar flew ("Everyone flies-- why not?") to a music club in which a live song performance was going on (the real singer crooning into her computer in real time from somewhere.) The singer recognized Philip Linden in the on-screen audience and greeted him from the on-screen stage.
"More is different," Rosedale explained. People think they want total and solitary control of their world, but the result of that is uninteresting. To get the emergent properties that make "Second Life" so enthralling, it has to be one contiguous world with everyone in it. At present it comprises about 100 square miles, mostly mainland, with some 5,000 islands (all adding up to 35 terrabytes running in 5,000 servers). Defying early predictions, the creativity in "Second Life" has not plateaued but just keeps escalating. Everybody is inspired to keep topping each other with ever cooler things. There are tens of thousands of clothing designers. Unlike the aesthetic uniformity of imagined digital worlds like in the movie "The Matrix," "Second Life" is suffused with variety. It is "the sum of our dreams."
The burgeoning token economy in "Second Life" is directly connected to the real-world economy with an exchange rate of around 270 Linden dollars to 1 US dollar. There are 7,000 businesses operating in "Second Life," leading this month to its first real-world millionaire (Metaverse real estate mogul Anshe Chung). At present "Second Life" has annual economic activity of about $70 million US dollars, growing rapidly.
As Jaron Lanier predicted in the early '90s, the only scarce resource in virtual reality is creativity, and it becomes valued above everything. Freed of the cost of goods and the plodding quality of real-world time, Rosedale explained, people experiment fast and strange, get feedback, and experiment again. They orgy on the things they think they want, play them out, get bored, and move on. They get "married," start businesses with strangers-- "There are 40-person businesses made of people who have never met in real life." Real-world businesses hold meetings in "Second Life" because they're more fun and encourage a higher degree of truth telling.
Pondering the future, Rosedale said that every aspect of the quality of shared virtual life will keep improving as the technology accelerates and the number of creators online keeps multiplying. ("Second Life" is now moving toward a deeper order of creativity by releasing most of its world-building software into open source mode.)
Real-world artifacts like New York City could become regarded like museums. "As the fastest moving, most creative stuff in our society increasingly takes place in the virtual world, that will change how we look at the real world," Rosedale concluded.

Larry Brilliant, Richard Rockefeller, & Katherine Fulton: The Deeper News About the New Philanthropy
### Philanthropic stamina
10,000 families in the US, Katherine Fulton reported, have assets of $100 million or more. That's up from 7,000 just a couple years ago. Most of that money is "on the sidelines." The poor and the middle class are far more generous in their philanthropy, proportionally, than the very wealthy.
Philanthropy across the board is in the midst of intense, potentially revolutionary, transition, she said. There's new money, new leaders, new rules, new technology, and new needs. Where great wealth used to come mainly from inheritance and oil, now it comes from success in high technology and finance-- and ideas and expectations from those business experiences inform (and sometimes over-simplify) the new philanthropy. Some of the great older institutions like the Rockefeller Foundation are radically reorganizing around new ideas and opportunities. But still the greatest amount comes from individuals, many of whom are now "giving while living" instead of handing over the task to heirs.
One major new instrument for philanthropy are the community
foundations, "the mutual funds of philanthropy, where donors can outsource their strategy." There are 1,000 such organizations in the world, 700 of them in the US, led by innovators such as Acumen Fund, Social Venture Partners, New Profit Inc., and Women's Funding Network.
Online giving is growing rapidly, including the development of
philanthropic marketplaces for direct, selective, fine-grain giving. Give India, for example, is a national marketspace of charity exchange. "By 2020," Katherine predicted, "we will see a headline, OPEN SOURCE PHILANTHROPIC PORTAL TOPS $1 BILLION IN GIFTS."
Katherine drew a matrix to classify kinds of philanthropy, with
Short-term & Responsive on the left, Long-term & Systemic on the right; Personal & Local on the bottom, Global on the top. An important trend is from the lower left to upper right, from local and short-term toward global and systemic, exemplified by Bill Gates's move from bringing computers to American schools to bringing health to Africa.
"Philanthropy is how we make the long now personal," she said. The trait most often missing in philanthropy, including the new philanthropy, is stamina, patience. "Instead of rewarding success with continued funding, the givers get bored and look for something new. Really effective giving requires deep contextual understanding and tolerance for ambiguity. My advice to new donors is, 'Pick at least one difficult and complex issue and stick with it, and join with others to work on it.'"
The greatest needs require philanthropic stamina but will also reward it. She quoted Danny Hillis: "There are problems that are impossible if you think about them in two-year terms-- which everyone does- but they're easy if you think if fifty-year terms."
Richard Rockefeller and Larry Brilliant joined Katherine on the
stage, and discussion got going that wound up lasting to 1am at dinner with the sponsors of the Seminar series. One subject was the isolation that often comes with great personal wealth. Katherine emphasized that donors have to visit up close with whatever they're giving toward. Dr. Rockefeller supported that, describing how different his view was of Doctors Without Borders once he had worked with the physicians in the field in Peru and Nigeria. He said that
direct experience helps free you from lots of theories that are just wrong, and from philanthropy that is a projection of your own neuroses.
Questions from the audience revealed a continuing problem with the whole social sector, which is the lack of clear mechanisms of self-correction and accountability. Government has checks and balances. Business has the bottom line. But "it's hard to speak truth to philanthropy," Katherine said. Richard said he looked closely at a $20 million effort by the Robert Wood Johnson to evaluate its programs and was unimpressed by the result. Larry Brilliant added, "And the new philanthropy is even less accountable
than the old."
Over dinner the subject came back to the 10,000 families with over $100 million dollars, most of it inactive. One problem is that giving really large grants is harder than small grants. Only
universities are well geared to attract and receive the multi-million dollar gifts that result in named buildings and additions to already bloated endowments. New institutions and mechanisms are needed for directing large grants in new directions.
And something generational is going on, Katherine mused. The generation of Andrew Carnegie and Richard's great grandfather John D. Rockefeller had a strong religious tradition that inspired them to public generosity and inventiveness. Those who came of age in the 1960s and early '70s had their experience with political activism as a driver for later philanthropy. "But I notice that many who became adults during and after Ronald Reagan seem to have no framework at all for giving."
