  • The key to reducing information overload is to more efficiently find the data you want among the information that you don’t care about.
  • at about the blogs where one in five or one in 10 posts are relevant for you?
  • the real magic is in filtering.
  • My favorite filtering tool is Yahoo Pipes
  • which lets me filter an RSS feed using various criteria: URL, author, date, content and more. 
  • and my some blogs filtered for just the best posts using PostRank.
  • The best thing about PostRank is that you can get an RSS feed of just the best posts from a particular publisher, and that feed then includes the PostRank score,
  • you can do even more hacking on the PostRank RSS feed using Yahoo Pipes.
  • Another technique that helps me to consume information more efficiently is to modify the format of many of my RSS feeds
  • By bringing more details into the title, I can avoid spending time clicking to get more information.
  • The final trick is to use Web APIs to gather additional data

    There is more information available in the world than any one person could hope to consume (hundreds of exabytes of data), but most of that information is uninteresting, out of date, inaccurate, or not relevant for you. The key to reducing information overload is to more efficiently find the data you want among the information that you don't care about.

…My heart's in Accra » CHI keynote: Desperately Seeking Serendipity - 1 views

  • Cities embody political decisions make by their designers.
    • David McGavock
       
      Sounds like program or be programmed to me
  • It’s much harder to get the architects behind Facebook or Foursquare articulate the behaviors they’re trying to enable and the political assumptions that underly those decisions.
    • David McGavock
       
      Again - Programmers!
  • An urban planner who wants to make changes to a city’s structure is held in check by a matrix of forces: a desire to preserve history, the needs and interests of businesses and residents in existing communities, the costs associated with executing new projects. Progress is slow,

  • For those planning the future of Facebook, it’s hard to study what’s succeeded and failed for MySpace, in part because an exodus of users to Facebook is gradually turning MySpace into a ghost town.
  • If we learn from real-world cities instead of abandoned digital ones, what lessons might we take?
    • David McGavock
       
      Conclusions
  • The Jacobs/Moses debate suggests we need to be cautious of architectures that offer convenience and charge isolation as a price of admission. This is the concern Eli Pariser articulates in his (excellent) new book, “The Filter Bubble“.
  • He worries that between Google’s personalized search and the algorithmic decisions Facebook makes in displaying news from our friends, our online experience is an increasingly isolated one,
  • They’re cars, rather than public transit or busy sidewalks.
  • A map of Vancouver overlaid with my friends’ recommendations is one thing; one that recommends restaurants based on paid advertisements and doesn’t reveal this practice is another entirely.
  • The map I want is the one that lets me shuffle not just through my friends’ preferences but through annotations from different groups: first time visitors to the city; long-time Vancouverites; foodies; visitors from Japan, Korea or China.
    • David McGavock
       
      A diverse sampling of taste
  • People’s actions inscribe their intentions onto a city.
  • Online spaces are often so anxious to show me how my friends are using a space that they obscure how other audiences are using it.
  • It’s possible to find out what’s popular on Facebook to an audience broader than that of your friends.
    • David McGavock
       
      Something Google+ should consider
  • One of the reasons curation is such a helpful strategy for wandering is that it reveals community maxima. It can be helpful to know that Times Square is the most popular tourist destination in New York if only so we can avoid it.
  • knowing where Haitian taxi cab drivers go for goat soup is often useful data on where the best Haitian food is to be found.
  • If you want to explore beyond the places your friends think are the most enjoyable, or those the general public thinks are enjoyable, you need to seek out curators who are sufficiently far from you in cultural terms and who’ve annotated their cities in their own ways.
    • David McGavock
       
      key to breaking the filter bubbles
  • Geocaching is its own peculiar form of community annotation, where the immediate goal is leaving your signature on someone else’s logbook, but the deeper goal is encouraging you to explore in a way you otherwise wouldn’t.
  • SF0, founded by a trio of Chicagoans transplanted to San Francisco, was designed to encourage players to discover things they’d never seen or done in the city, in a way that encouraged independence and exploration.
  • Combining the insights we may find from studying the organization of cities with the ability to reshuffle and sort digitally may let us think about designing online spaces for serendipity in different and powerful ways.
    • David McGavock
       
      Conclusion?
  • - How do we design physical spaces to encourage serendipity? - What lessons about serendipity in physical spaces can we bring into the virtual realm? - How can we annotate the physical world, digitally, in ways that expand our encounters with the world, rather than limiting them?
    • David McGavock
       
      Questions over conclusion
  • We hope that cities are serendipity engines. By putting a diverse set of people and things together in a confined place, we increase the chances that we’re going to stumble onto the unexpected. It’s worth asking the question: do cities actually work this way?
  • Most of us are fairly predictable
  • We hope for random encounter with a diverse citizenry to build a web of weak ties that increases our sense of involvement in the community, as Bob Putnam suggested in Bowling Alone. And we worry that we may instead isolate and cocoon ourselves when faced with a situation where we feel like outsiders, as Putnam’s recent research suggests.
  • “Census data can describe the segregation of my block, but how about telling me how segregated my life is? Location data points in that direction.
  • Nathan Eagle, who has worked with Sandy Pentland at MIT’s Media Lab on the idea of “reality mining”, digesting huge sets of data like mobile phone records, estimates that he can predict the location of “low-entropy individuals” with 90-95% accuracy based on this type of data
  • We all filter the places we live into the places where we’re regulars and the ones we avoid, the parts of town where we feel familiar and where we feel foreign. We do this based on where we live, where we work, and who we like to spend time with.
  • I’m less concerned about left-right polarization in the US, and more concerned about us/them polarization around the world
  • through the design of the systems we use and our behavior with those systems, I see reasons to worry that our use of the internet may be less cosmopolitan and more isolated that we would hope.
  • There were – and are – reasons to distrust curators, but there’s a critical aspect of their work I believe we need to preserve as we move towards new models for organizing news.
    • David McGavock
       
      interesting view of curation
  • Countries that have more than 40 million or more internet users generally have a very strong bias towards local sources – the mean is roughly 95%/5%, which makes Americans look (slightly) cosmopolitan in comparison.
  • US broadcast media focuses much more on entertainment stories than on international news.)
  • What’s striking to me about this preference data is that there’s so little effort required to access international news sources like BBC, the Times of India or the Mail and Guardian – they’re one click away and don’t require crossing a language barrier – and how strong the “local” bias for national news sources appears to be.
  • on January 12th, I published “What if Tunisia had a revolution, but nobody watched?“… and I got a lot of phone calls when Ben Ali fled the country two days later.
  • The revolution in Tunisia caught intelligence and diplomatic services around the world flat-footed. It didn’t have to – there was a wealth of information being published on Tunisian Facebook pages
  • I’m forced to admit that there’s no way I would have known about the revolution brewing if I didn’t have close Tunisian friends.
  • I’m less interested in the ways in which we limit our paths through cities than in how we constrain what we do and don’t encounter online.
    • David McGavock
       
      key point
  • On the other hand, curators invariably have biases
  • We need mechanisms to ensure that search gets complemented with serendipity.
    • David McGavock
       
      Point we have been discussing. Filter bubbles
  • Facebook offers a different answer to the question, “What do I need to know?” – “You need to know what your friends and your friends of friends already know that you do not.”
    • David McGavock
       
      Facebook world = ummm....
  • there’s a decent chance that their collective intelligence has some blind spots
  • The problem, of course, is that if your friends don’t know about a revolution in Tunisia or a great new Vietnamese restaurant, you may not know either.
  • It’s worth asking whether that bubble is able to provide us with the serendipity we hope for from the web.
  • Serendipity, at first glance, looks like the positive side of unintended consequences, the happy accident. But that’s not what the term meant, at least originally.
  • The word was coined by Horace Walpole, an 18th century British aristocrat,
  • A Google search turns up 11 million pages with the term, including restaurants, movies and gift shops named “serendipity”, but very few on unexpected discovery through sagacity.
    • David McGavock
       
      Serendipity vs. Sagacity
  • he refers to a Persian fairy tale, The Three Princes of Serendip, in which the titular characters were “always making discoveries, by accidents and sagacity, of things they were not in quest of.”
  • Louis Pasteur observed, “In the fields of observation chance favors only the prepared mind.”
  • In “The Travels and Adventures of Serendipity”, he and Barber explore discovery in a General Electric laboratory under the leadership of Willis Whitney, who encouraged a work environment that focused as much on fun as it did on discovery.
    • David McGavock
       
      Sounds like Google. Tinkering, time to play, time to work.
  • If we want to create online spaces to encourage serendipity, we might start by learning from cities.
    • David McGavock
       
      Moving to the point of online learning
  • Our loss, I believe, is that we’ve lost sight of the idea that we could prepare ourselves for serendipity, both personally and structurally.
  • vibrancy comes from the ongoing chance encounter between people using a neighborhood for different purposes, encountering one another as their paths intersect and cross.
  • The neighborhoods Jacobs celebrates are certainly not the most efficient in terms of an individual’s ability to move quickly and independently. Vibrancy and efficiency may not be diametrically opposed, but it’s likely that the forces are in tension.

The Myth Of AI | Edge.org - 1 views

  • what I'm proposing is that if AI was a real thing, then it probably would be less of a threat to us than it is as a fake thing.
  • it adds a layer of religious thinking to what otherwise should be a technical field.
  • we can talk about pattern classification.
  • ...38 more annotations...
  • But when you add to it this religious narrative that's a version of the Frankenstein myth, where you say well, but these things are all leading to a creation of life, and this life will be superior to us and will be dangerous
  • I'm going to go through a couple of layers of how the mythology does harm.
  • this overall atmosphere of accepting the algorithms as doing a lot more than they do. In the case of Netflix, the recommendation engine is serving to distract you from the fact that there's not much choice anyway.
  • If a program tells you, well, this is how things are, this is who you are, this is what you like, or this is what you should do, we have a tendency to accept that.
  • our economy has shifted to what I call a surveillance economy, but let's say an economy where algorithms guide people a lot, we have this very odd situation where you have these algorithms that rely on big data in order to figure out who you should date, who you should sleep with, what music you should listen to, what books you should read, and on and on and on
  • people often accept that
  • all this overpromising that AIs will be about to do this or that. It might be to become fully autonomous driving vehicles instead of only partially autonomous, or it might be being able to fully have a conversation as opposed to only having a useful part of a conversation to help you interface with the device.
  • other cases where the recommendation engine is not serving that function, because there is a lot of choice, and yet there's still no evidence that the recommendations are particularly good.
  • there's no way to tell where the border is between measurement and manipulation in these systems.
  • if the preponderance of those people have grown up in the system and are responding to whatever choices it gave them, there's not enough new data coming into it for even the most ideal or intelligent recommendation engine to do anything meaningful.
  • it simply turns into a system that measures which manipulations work, as opposed to which ones don't work, which is very different from a virginal and empirically careful system that's trying to tell what recommendations would work had it not intervened
  • What's not clear is where the boundary is.
  • If you ask: is a recommendation engine like Amazon more manipulative, or more of a legitimate measurement device? There's no way to know.
  • we don't know to what degree they're measurement versus manipulation.
  • If people are deciding what books to read based on a momentum within the recommendation engine that isn't going back to a virgin population, that hasn't been manipulated, then the whole thing is spun out of control and doesn't mean anything anymore
  • not so much a rise of evil as a rise of nonsense.
  • because of the mythology about AI, the services are presented as though they are these mystical, magical personas. IBM makes a dramatic case that they've created this entity that they call different things at different times—Deep Blue and so forth.
  • Cortana or a Siri
  • This pattern—of AI only working when there's what we call big data, but then using big data in order to not pay large numbers of people who are contributing—is a rising trend in our civilization, which is totally non-sustainable
    • David McGavock
       
      Key relationship between automation of tasks, downsides, and expectation for AI
  • If you talk about AI as a set of techniques, as a field of study in mathematics or engineering, it brings benefits. If we talk about AI as a mythology of creating a post-human species, it creates a series of problems that I've just gone over, which include acceptance of bad user interfaces, where you can't tell if you're being manipulated or not, and everything is ambiguous.
  • It creates incompetence, because you don't know whether recommendations are coming from anything real or just self-fulfilling prophecies from a manipulative system that spun off on its own, and economic negativity, because you're gradually pulling formal economic benefits away from the people who supply the data that makes the scheme work.
  • I'm going to give you two scenarios.
  • let's suppose somebody comes up with a way to 3-D print a little assassination drone that can go buzz around and kill somebody. Let's suppose that these are cheap to make.
  • Having said all that, let's address directly this problem of whether AI is going to destroy civilization and people, and take over the planet and everything.
  • some disaffected teenagers, or terrorists, or whoever start making a bunch of them, and they go out and start killing people randomly
  • This idea that some lab somewhere is making these autonomous algorithms that can take over the world is a way of avoiding the profoundly uncomfortable political problem, which is that if there's some actuator that can do harm, we have to figure out some way that people don't do harm with it.
    • David McGavock
       
      Another key - focus on the actuator, not the agent that exploits it.
  • the part that causes the problem is the actuator. It's the interface to physicality
  • not so much whether it's a bunch of teenagers or terrorists behind it or some AI
  • The sad fact is that, as a society, we have to do something to not have little killer drones proliferate.
  • What we don't have to worry about is the AI algorithm running them, because that's speculative.
  • another one where there's so-called artificial intelligence, some kind of big data scheme, that's doing exactly the same thing, that is self-directed and taking over 3-D printers, and sending these things off to kill people.
  • There's a whole other problem area that has to do with neuroscience, where if we pretend we understand things before we do, we do damage to science,
  • You have to be able to accept what your ignorances are in order to do good science. To reject your own ignorance just casts you into a silly state where you're a lesser scientist.
  • To my mind, the mythology around AI is a re-creation of some of the traditional ideas about religion, but applied to the technical world.
  • The notion of this particular threshold—which is sometimes called the singularity, or super-intelligence, or all sorts of different terms in different periods—is similar to divinity.
  • In the history of organized religion, it's often been the case that people have been disempowered precisely to serve what were perceived to be the needs of some deity or another, where in fact what they were doing was supporting an elite class that was the priesthood for that deity.
    • David McGavock
       
      Technical priesthood.
  • If AI means this mythology of this new creature we're creating, then it's just a stupid mess that's confusing everybody, and harming the future of the economy. If what we're talking about is a set of algorithms and actuators that we can improve and apply in useful ways, then I'm very interested, and I'm very much a participant in the community that's improving those things.
  • A lot of people in the religious world are just great, and I respect and like them. That goes hand-in-hand with my feeling that some of the mythology in big religion still leads us into trouble that we impose on ourselves and don't need.
  •  
    "The idea that computers are people has a long and storied history. It goes back to the very origins of computers, and even from before. There's always been a question about whether a program is something alive or not since it intrinsically has some kind of autonomy at the very least, or it wouldn't be a program. There has been a domineering subculture-that's been the most wealthy, prolific, and influential subculture in the technical world-that for a long time has not only promoted the idea that there's an equivalence between algorithms and life, and certain algorithms and people, but a historical determinism that we're inevitably making computers that will be smarter and better than us and will take over from us."

Q&A: David Eagleman, Director, Initiative on Neuroscience and the Law | SmartPlanet - 1 views

  • David Eagleman is about as close to a rock star that a neuroscientist can be.
  • Eagleman was excited to talk to SmartPlanet about his work at both the Initiative on Neuroscience and Law, a national, interdisciplinary organization he founded that’s looking at how to remake the U.S. legal system; and the Laboratory for Perception and Action, at Baylor College of Medicine. The former initiative tackles topics such as how brain imaging and analyses of “Big Data” on crime patterns can help communities better understand and prevent violent behavior in new ways. The latter looks broadly at how individual brains are not at all alike — and how the differences might be significant for how we construct and manage our societies.
  • His work is particularly relevant in policy-related discussions in the aftermath of the Sandy Hook Elementary School tragedy in Connecticut.
  • ...13 more annotations...
  • “To the newsreaders who feel that mental illness is best viewed as an excuse, let me suggest instead that we might more effectually recognize it as a national priority for social policy,” he wrote on his blog shortly after the shootings.  “If we care to prevent the next mass shooting, we should concentrate our efforts on getting meaningful diagnoses and resources to the next Adam Lanza.”
  • Because we are able now to measure things we have never been able to measure before, this allows us potentially to customize sentencing and rehabilitation. The goal is to have the whole system be more just and have more utility.
  • Our system is built on the assumption that if you’re over 18 and over the IQ of 70, you’re a practical reasoner, free to choose how you act. But modern neuroscience suggests that those are not good assumptions.
  • I have to emphasize, though, that this is not about exculpation. I have to be very clear that this is really about customized sentencing and rehab that works.
  • It’s helpful to be able to talk about science in basic ways that anyone can understand. What I tell my students in my lab is that they need to be able explain their research to an 8th grader.
  • I’m an amateur history buff, and if I want to read about the Roman Empire, I don’t want to read an academic debate, but instead a narrative by a trusted guide who’s done their homework, who will offer the filter of how they understand the Roman Empire, to shepherd me through its history in only 200 pages.
  • Rather than “playful,” I’d say that my approach is simply the opposite of boring. It’s about looking for and then trying to answer questions that are poweful enough to get you out of bed at 5AM.
  • My intuition on this idea: being a good scientist or creative writer is about maintaining the wide-eyed wonder of a child and asking questions all the time. That’s what really makes discovery happen in any field.
  • Science is changing really rapidly. One way is that lots of scientists are moving into Big Data
  • Right now we’re involved with serious crunching to pull out statistical info on recidivism and crime. Our first challenge is visualizing it. So in this sense, creativity and art also relevant. Data visualization is really valuable stuff; you can discover a trend when you see, wow, I didn’t realize that bump would be there. To be able to tie together data in beautiful ways allows us to see and discover patterns.
  • I don’t have any fear about losing the mystery of creativity. If I explain every single chemical piece in the process of why you enjoy the taste of a soy latte, it wouldn’t diminish your enjoyment of a soy latte. It might even enhance it
  • Neuroscientists work on how to understand how brains construct reality in general, but we are in the position of fish trying to understand water. What I mean by that is that we only know one way of seeing the world very well, like a fish only knows water.  Learning about how synesthesia works allows us to get out of our fishbowl,
  • You don’t need to know anything about the brain to understand what shape or style will be appealing. We may come scrambling up behind advertisers and product designers and validate them. If Apple wanted to hire me, sure, I’d say yes immediately and do the best job I could! But honestly, they already know how to do it. They’re the design experts. We neuroscientists would in come with our fancy machines and theories and explain why what they do is already true.

How the brain creates the 'buzz' that helps ideas spread - 1 views

  • UCLA psychologists have taken a significant step toward answering these questions, identifying for the first time the brain regions associated with the successful spread of ideas, often called "buzz."
  • "Our study suggests that people are regularly attuned to how the things they're seeing will be useful and interesting, not just to themselves but to other people,"
  • We always seem to be on the lookout for who else will find this helpful, amusing or interesting, and our brain data are showing evidence of that.
  • ...6 more annotations...
  • The study findings are published in the online edition of the journal Psychological Science, with print publication to follow later this summer.
  • "Now we have mapped the brain regions associated with ideas that are likely to be contagious and are associated with being a good 'idea salesperson.' In the future, we would like to be able to use these brain maps to forecast what ideas are likely to be successful and who is likely to be effective at spreading them."
  • the interns who were especially good at persuading the producers showed significantly more activation in a brain region known as the temporoparietal junction, or TPJ, at the time they were first exposed to the pilot ideas they would later recommend.
  • We found that increased activity in the TPJ was associated with an increased ability to convince others to get on board with their favorite ideas.
  • Thinking about what appeals to others may be even more important."
  • The TPJ, located on the outer surface of the brain, is part of what is known as the brain's "mentalizing network," which is involved in thinking about what other people think and feel.
  •  
    Interesting findings. The emphasis here is on identifying activity of the brain that indicates a person's effectiveness with passing on (sharing) information. While that is notable, it would be great to know what activity indicates that the information has merit in and of itself. We have plenty of buzz in our world. What we need are authoritative sources.

What Happened to Downtime? The Extinction of Deep Thinking & Sacred Space :: Articles :... - 0 views

  • /// article Appreciate (989) Tweet (512) Comment (106) What Happened to Downtime? The Extinction of Deep Thinking & Sacred Space by Scott Belsky Interruption-free space is sacred. Yet, in the digital era we live in, we are losing hold of the few sacred spaces that remain untouched by email, the internet, people, and other forms of distraction. Our cars now have mobile phone integration and a thousand satellite radio stations. When walking from one place to another, we have our devices streaming data from dozens of sources. Even at our bedside, we now have our iPads with heaps of digital apps and the world's information at our fingertips.
  • Why do we crave distraction over downtime?

Why do we give up our sacred space so easily? Because space is scary.
  • It is now possible to always feel loved and cared for, thanks to the efficiency of our “comment walls” on Facebook and seamless connection with everyone we've ever known. Your confidence and self-esteem can quickly be reassured by checking your number of “followers” on Twitter or the number of “likes” garnered by your photographs and blog posts.

  • We need some rules. When it comes to scheduling, we will need to allocate blocks of time for deep thinking. Maybe you will carve out a 1-2 hour block on your calendar every day for taking a walk or grabbing a cup of coffee and just pondering some of those bigger things.
  • 3. Meditation and naps to clear the mind.

  • It is supremely important that we recognize the power of our insecurities and, at the very least, acknowledge where our anxiety comes from. Awareness is always the first step in solving any problem.

Skeptic » About Us » A Brief Introduction - 1 views

  •  
    "A Brief Introduction All our science, measured against reality, is primitive and childlike - and yet it is the most precious thing we have. -Albert Einstein The Skeptics Society is a scientific and educational organization of scholars, scientists, historians, magicians, professors and teachers, and anyone curious about controversial ideas, extraordinary claims, revolutionary ideas, and the promotion of science. Our mission is to serve as an educational tool for those seeking clarification and viewpoints on those controversial ideas and claims. Under the direction of Dr. Michael Shermer, the Society engages in discussions with leading experts and investigates fringe science and paranormal claims. It is our hope that our efforts go a long way in promoting critical thinking and lifelong inquisitiveness in all individuals. I have made a ceaseless effort not to ridicule, not to bewail, not to scorn human actions, but to understand them. -Baruch Spinoza Some people believe that skepticism is the rejection of new ideas, or worse, they confuse "skeptic" with "cynic" and think that skeptics are a bunch of grumpy curmudgeons unwilling to accept any claim that challenges the status quo. This is wrong. Skepticism is a provisional approach to claims. It is the application of reason to any and all ideas - no sacred cows allowed. In other words, skepticism is a method, not a position. Ideally, skeptics do not go into an investigation closed to the possibility that a phenomenon might be real or that a claim might be true. When we say we are "skeptical," we mean that we must see compelling evidence before we believe. Skepticism has a long historical tradition dating back to ancient Greece, when Socrates observed: "All I know is that I know nothing." But this pure position is sterile and unproductive and held by virtually no one. If you were skeptical about everything, you would have to be skeptical of your own skepticism. Like the dec

  • Before we deal with dueling data layers, we’ve got some concrete challenges to take on. Just because data exists to annotate a physical place doesn’t mean it’s accessible
  • How do we encourage productive participation?
  • “How do we help marginal and rarely-heard voices find an audience?”
  • How do we map and understand media ecosystems?

  • What is the effect of online availability ofjournal issues? It is possible that by makingmore research more available, online searchingcould conceivably broaden the work cited andlead researchers, as a collective, away from the“core”journals of their fields and to dispersedbut individually relevant work. I will show,however, that even as deeper journal back is-sues became available online, scientists andscholars cited more recent articles; even asmore total journals became available online,fewer were cited

      Thesis
  • Figure 1 shows the speed of the shift toward commercial and free electronic provision of articles, and how deepening backfiles have made more early science readily available in recent years.
    • srgupta
       
      Clear evidence of increase in accessibility and availability of articles.
  • Panel regression models were used to explore the relation between online article availability and citation activity—average historical depth of citations, number of distinct articles and journals cited, and Herfindahl concentration of citations to particular articles and journals—over time (details on methods are in the Supporting Online Material)

      Methodology
  • ...6 more annotations...
  • The graphs in Fig. 2 trace the influence of online access, estimated from the entire sample of articles, and illustrated for journals and subfields with the mean number of citations. Figure 2A shows the simultaneous effect of commercial and free online availability on the average age of citations
  • The first question was whether depth of citation—years between articles and the work they reference—is predicted by the depth of journal issues online—how many years back issues were electronically available during the previous year when scientists presumably drafted them into their papers.
  • Collectively, the models presented illustrate that as journal archives came online, either through commercial vendors or freely, citation patterns shifted. As deeper backfiles became available, more recent articles were referenced; as more articles became available, fewer were cited and citations became more concentrated within fewer articles. These changes likely mean that the shift from browsing in print to searching online facilitates avoidance of older and less relevant literature. Moreover, hyperlinking through an online archive puts experts in touch with consensus about what is the most important prior work—what work is broadly discussed and referenced. With both strategies, experts online bypass many of the marginally related articles that print researchers skim. If online researchers can more easily find prevailing opinion, they are more likely to follow it, leading to more citations referencing fewer articles. Research on the extreme inequality of Internet hyperlinks (14), scientific citations (15, 16), and other forms of “preferential attachment” (17, 18) suggests that near-random differences in quality amplify when agents become aware of each other’s choices. Agents view others’ choices as relevant information—a signal of quality—and factor them into their own reading and citation selections. By enabling scientists to quickly reach and converge with prevailing opinion, electronic journals hasten scientific consensus. But haste may cost more than the subscription to an online archive: Findings and ideas that do not become consensus quickly will be forgotten quickly .

      Conclusion and possible explanation
  • This research ironically intimates that one of the chief values of print library research is poor indexing. Poor indexing—indexing by titles and authors, primarily within core journals— likely had unintended consequences that assisted the integration of science and scholarship. By drawing researchers through unrelated articles, print browsing and perusal may have facilitated broader comparisons and led researchers into the past. Modern graduate education parallels this shift in publication—shorter in years, more specialized in scope, culminating less frequently in a true dissertation than an album of articles (19)
    • srgupta
       
      I have a hard time accepting this. A hint of nostalgia for the "old way" of doing things?
  • As 21st-century scientists and scholars use online searching and hyperlinking to frame and publish their arguments more efficiently, they weave them into a more focused—and more narrow—past and present.
    • srgupta
       
      Empirical results are convincing, but this isn't a given. New medium enables new forms of knowledge, and requires new forms of know-how.

    An empirical study of how the shift from print to online publication of journals has changed citation, research, and reading habits. Compelling use of data, though I find the some of the explanations somewhat tenuous.

How Hashtagging the Web Could Improve Our Collective Intelligence - 0 views

  • Why all the fuss over tweets? Twitter hosts valuable, communal conversation in real-time. And Twitter trends become more powerful the more users contribute to the dialogue. Finally, Twitter allows the chatter of millions to be parsed into channels (hashtags) of real-time conversation that covers widely varying topics. Jokes, rumors, political movements, pop culture fanaticisms, the collective screaming of teenagers — they all bubble to the surface and shift and change like an oil slick, much like a collective human consciousness.
  • One thing that makes Twitter so powerful is its use of a standard language: hashtags. Any hashtagged tweet is automatically linked to every other tweet that shares the same tag. This allows for consistent dialogue and measurement. However, the Internet as a whole is not a very consistent medium. Patterns emerge in specific areas of the web, but no uniform underlying structure exists to merge these patterns. Content may go viral or score a high page rank, but it doesn’t easily connect to related topics or encourage a larger conversation. It is a frustrating vestige of print culture that my web curation should be limited by my search ability.
  • Twitter can gather direct, mass conversation into subject categories like #watermelon, but the conversation is limited by the short form nature of the platform. If longer form methods of online communication could be aggregated into a similar form of direct conversation, it would serve both spectators and authors alike. For that to happen, citation must be standardized. Current citation methods like hashtags are rarely, if ever, exhaustive, and they often take on the subjective viewpoint of the author or sharer. Imagine the level of constructive debate and creativity that we might achieve when we organize and bucket all web content into Twitter-like categories. Imagine the kinds of things we might learn about our collective culture.

The Evolution of Cooperation* - 1 views

  • To find a good strategy to use in such situations, I invited experts in game theory to submit programs for a computer Prisoner’s Dilemma tournament – much like a computer chess tournament.

      These conditions are core.
  • What made this mutual restraint possible was the static nature of trench warfare, where the same small units faced each other for extended periods of time. The soldiers of these opposing small units actually violated orders from their own high commands in order to achieve tacit cooperation with each other
  • data from these tournaments reveals four properties which tend to make a strategy successful: avoidance of unnecessary con- flict by cooperating as long as the other player does, provocability in the
  • the individuals involved do not have to be rational: The evolutionary process allows successful strategies to thrive, even if the players do not know why or how. Nor do they have to exchange messages or commit- ments: They do not need words, because their deeds speak for them. Likewise, there is no need to assume trust between the players: The use of reciprocity can be enough to make defection unproductive. Altruism is not needed: Successful strategies can elicit cooperation even from an egoist. Finally, no central authority is needed: Cooperation based on reciprocity can be self-policing
  • An indefinite number of interactions, therefore, is a condition under which cooperation can emerge

      This condition is especially important in the case of egoists. Relationship over time.
  • So there must be some clustering of individuals who use strategies with two properties: The strategy cooperates on the first move, and discriminates between those who respond to the cooperation and those who do not
    • David McGavock
       
      The check for reciprocation is a bit of evidence that the other side knows the value of the move of cooperation; that they won't be abandoned.
  • Whether the players trust each other or not is less important in the long run than whether the conditions are ripe for them to build a stable pattern of cooperation with each other
  • It turns out that if one waits to respond to uncalled-for defections, there is a risk of sending the wrong signal. The longer defections are allowed to go unchallenged, the more likely it is that the other player will draw the conclusion that defection can pay.
    • David McGavock
       
      Immediate feedback appears to be important in many domains.
  • The foundation of cooperation is not really trust, but the durability of the relationship.
  • Waiting for probes to accumulate only risks the need for a response so large as to evoke yet more trouble.

      I have found that testing limits is a factor in working with children and adults. We are alert to the boundaries.
  • For this reason, the only arms control agreements which can be stable are those whose violations can be detected soon enough. The critical requirement is that violations can be detected before they can accumulate
  • Therefore, the advice to players of the Prisoner’s Dilemma might serve as good advice to national leaders as well: Don’t be envious, don’t be the first to defect, reciprocate both cooperation and defection, and don’t be too clever.
  • We are used to thinking about competitions in which there is only one winner, competitions such as football or chess. But the world is rarely like that. In a vast range of situations, mutual cooperation can be better for both sides than mutual defection. The key to doing well lies not in overcoming others, but in eliciting their cooperation
    • David McGavock
       
      Herein lies another key... that we have a cooperative (win-win) attitude and understanding of the "game". We see our survival as tied with not exclusive of the fate of the "other".
