The Dirty Little Secret About the "Wisdom of the Crowds" - There is No Crowd - 0 views

  • Wikipedia isn't written and edited by the "crowd" at all. In fact, 1% of Wikipedia users are responsible for half of the site's edits. Even Wikipedia's founder, Jimmy Wales, has been quoted as saying that the site is really written by a community, "a dedicated group of a few hundred volunteers."
  • I think your headline is misleading and Vassilis Kostakos should read the book before poking holes. Surowiecki is very clear about the conditions necessary for a wise crowd to prevail and those conditions are: 1. Diversity of opinion 2. Independence 3. Decentralization 4. Aggregation If your crowd possesses those qualities then it is wise and then it will be better at making decisions under Surowiecki's paradigm. The crowds used in the research (and the crowd in general) doesn't possess those qualities and therefore is an unfit data set. We should be trying to create the ideal crowd before we can obtain superlative results and not try to get good results from any random crowd.
  • Limitations in predictions market are well documented (and include Muhammad's points above), and constrain their practical application to a well-defined number of situation. Crowdsourcing suffers from the same limitations, which is not a problem, as long as you limit its application correspondingly. The problem occur when you stretch it outside the required constraints and yet present the results as "scientific", i.e. as a good proxy for what the crowd thinks. That's what professor Vassilis Kostakos's theory ultimately comes down to (or should - I don't know, I haven't read his report). Apps like Digg or Amazon's review are not scientific applications of crowdsourcing, and thus their results should not be seen as precise representation of our collective thinking.

  • Wisdom of Crowds is a crypto-fascist idea; there is no objective truth, there are no facts, truth is what "the crowd" decides it is. You get these unhealthy echo chambers of "activists" setting the agenda. This article said it best, over three years ago: DIGITAL MAOISM The Hazards of the New Online Collectivism By Jaron Lanier
  • What I'd like to see is non-fakeable metrics on ecommerce sites: return rates or reorder rates (as appropriate), for example. Or for apps, how many times users open the app per day/week or whatever.
  • the research is interesting if linked to ideas of unrepresentative or illiberal democracy, as posited by Fareed Zakaria that suggests small interest groups can hijack democratic systems.

Regaining some perspective | TechTicker - 0 views

  • I also sometimes wonder what role – if any – that the writing process (blogging) has played in this. This is hardly to suggest that blogging makes you a radical. However through ongoing reflection and exploration of ideas, I think it can solidify and sharpen existing opinions, and take what may have once been only the seeds of thought and grow them into something far more substantial.
  • In some regards the topic of education is just as contentious as that of politics, and all too easy to become divided by false or artificial delineations.  If we’re going to start to make progress and bring learning and teaching into the 21st century I think the best, most effective, and sustainable way to achieve this is to do it together.

Jimmy Wales: What the MSM Gets Wrong About Wikipedia -- and Why - 0 views

  • I believe that the underlying facts about the Wikipedia phenomenon -- that the general public is actually intelligent, interested in sharing knowledge, interested in getting the facts straight -- are so shocking to most old media people that it is literally impossible for them to report on Wikipedia without following a storyline that goes something like this: "Yeah, this was a crazy thing that worked for awhile, but eventually they will see the light and realize that top-down control is the only thing that works."

It's Time To Hide The Noise - 5 views

  • the noise is worse than ever. Indeed, it is being magnified every day as more people pile onto Twitter and Facebook and new apps yet to crest like Google Wave. The data stream is growing stronger, but so too is the danger of drowning in all that information.
  • the fact that Seesmic or TweetDeck or any of these apps can display 1,200 Tweets at once is not a feature, it’s a bug
  • if you think Twitter is noisy, wait until you see Google Wave, which doesn’t hide anything at all.  Imagine that Twhirl image below with a million dialog boxes on your screen, except you see as other people type in their messages and add new files and images to the conversation, all at once as it is happening.  It’s enough to make your brain explode.

  • all I need is two columns: the most recent Tweets from everyone I follow (the standard) and the the most interesting tweets I need to pay attention to.  Recent and Interesting.  This second column is the tricky one.  It needs to be automatically generated and personalized to my interests at that moment.

      How do you determine which are the most interesting tweets? What is your criteria?
    • Ed Webb
       
      Aye, there's the rub. This is where those clever algorithms come in that monitor your activity and make suggestions. Like Amazon recommendations. Er, which are always brilliantly spot-on. Or something.
  • search is broken on Twitter.  Unless you know the exact word you are looking for, Tweets with related terms won’t show up.  And there is no way to sort searches by relevance, it is just sorted by chronology.

Filtering Reality - The Atlantic (November 2009) - 1 views

  • Nearly every communication method we invent eventually conveys unwanted commercial messages. AR systems will be used for spam too, whether via graffiti-like tags, ads that pop up when you look too long at a shop, or even abstract symbols stuck to a wall or worn on a shirt that, when viewed through an AR system, turn into 3-D animations. Fortunately, just as Web browsers have pop-up blockers, AR systems will filter spam. Moreover, they’ll likely be able to filter out physical ads, too, such as billboards—a capability that many opponents of visual clutter will find deliriously attractive.
  • Conceivably, users could set AR spam filters to block any kind of unpalatable visual information, from political campaign signs to book covers. Parents might want to block sexual or violent images from their kids’ AR systems, and political activists and religious leaders might provide ideologically correct filters for their communities. The bad images get replaced by a red STOP, or perhaps by signs and pictures that reinforce the desired worldview.
  • It won’t take a majority of people using these filters to poison public discourse; imagine this summer’s town-hall screamers on constant alert, wherever they go. Yet this world will be the unintended consequence of otherwise desirable developments—spam filters, facial recognition, augmented reality—that many of us will find useful.

  • The harder answer, but ultimately the correct one, would be to strengthen our society’s ability to tolerate diverse viewpoints—to encourage not muddy centrism, but a basic ability to hear out, and to see, fellow citizens with a measure of respect.

elearnspace › The Problem with Literature Reviews - 6 views

  • a literature review is a controlling, heritage-preserving system

      Yes but they must still be done to get that doctorate. And probably be done several times along the way.
