Internet memory holes and filter bubbles O NOEZ!!1

Paul Raven @ 15-07-2011

Ah, here we go again – another study that totes proves that the intermawubz be makin’ us dumb. Perfect timing for career curmudgeon Nick Carr, whose new book The Shallows – which is lurking in my To Be Read pile as we speak – continues his earnest handwringing riff over our inevitable tech-driven descent into Morlockhood

Human beings, of course, have always had external, or “transactive,” information stores to supplement their biological memory. These stores can reside in the brains of other people we know (if your friend John is an expert on sports, then you know you can use John’s knowledge of sports facts to supplement your own memory) or in storage or media technologies such as maps and books and microfilm. But we’ve never had an “external memory” so capacious, so available and so easily searched as the web. If, as this study suggests, the way we form (or fail to form) memories is deeply influenced by the mere existence of external information stores, then we may be entering an era in history in which we will store fewer and fewer memories inside our own brains.

Do we actually store fewer and fewer memories, though? Or do we perhaps store the same amount as ever, while having an ever-growing external resource to draw upon, making the amount we can carry in the brainmeat look small by comparison to the total sphere of human knowledge, which is still growing at an arguably exponential rate? Or, to use web-native vernacular: citation needed. (If you can’t remember where you saw your supporting evidence, Nick, feel free to Google it; I won’t hold it against you.)

If a fact stored externally were the same as a memory of that fact stored in our mind, then the loss of internal memory wouldn’t much matter. But external storage and biological memory are not the same thing. When we form, or “consolidate,” a personal memory, we also form associations between that memory and other memories that are unique to ourselves and also indispensable to the development of deep, conceptual knowledge. The associations, moreover, continue to change with time, as we learn more and experience more. As Emerson understood, the essence of personal memory is not the discrete facts or experiences we store in our mind but “the cohesion” which ties all those facts and experiences together. What is the self but the unique pattern of that cohesion?

I submit that we form similar consolidations on a collective basis using the internet as a substrate; hyperlinks, aggregation blogs, tranches of bookmarks both personal and public. I further submit that this makes the internet no different to a dead-tree library except in its speed, depth and utility. This puts the internet at the end of a millennia-long chain of inventions that begun with cave-paintings and written language, all of which doubtless provoked sad eyes and headshaking from those who didn’t have a chance to grow up around them. It’s not the internet Carr fears, it’s change.

I’m usually very keen on Ars Technica‘s reporting on science papers, but there’s a glaringingly bad bit in the second paragraph of their piece on this one:

The potential to find almost any piece of information in seconds is beneficial, but is this ability actually negatively impacting our memory? The authors of a paper that is being released by Science Express describe four experiments testing this. Based on their results, people are recalling information less, and instead can remember where to find the information they have forgotten.

The authors pose one simple example that had me immediately agreeing with their conclusions. Test yourself: how many countries have flags with only one color? Regardless of your answer, was your first thought about actual flags, or was it to consider where you would find that information? Without realizing it (even though I knew the content of the paper), I found myself mentally planning on opening up my Web browser and heading for a search engine.

So a guy who writes articles for publication on the web, and presumably does much of his research using the internet too, is shocked to find his first response to a question he doesn’t immediately know the answer to is “hey, I wonder how I can Google this?” – is that really a surprise? As a former public library employee, my response would probably have been to wonder whereabouts to look in the stacks for the same information; reliance on what we might call “outboard” cultural memory storage is hardly a new thing. And unless you’re in the business of needing to be able to recall trivia without recourse to reference material – like a career pub-quiz participant, perhaps – I remain to be convinced that this is a drastic new failure condition that threatens the downfall of civilisation.

Indeed, a MetaFilter commenter recalls a Richard Feynman anecdote from a year when he was lecturing in Biology that illustrates the point very effectively:

The next paper selected for me was by Adrian and Bronk. They demonstrated that nerve impulses were sharp, single-pulse phenomena. They had done experiments with cats in which they had measured voltages on nerves.

I began to read the paper. It kept talking about extensors and flexors, the gastrocnemius muscle, and so on. This and that muscle were named, but I hadn’t the foggiest idea of where they were located in relation to the nerves or to the cat. So I went to the librarian in the biology section and asked her if she could find me a map of the cat.

“A map of the cat, sir?” she asked, horrified. “You mean a zoological chart!” From then on there were rumors about some dumb biology graduate student who was looking for a “map of the cat.”

When it came time for me to give my talk on the subject, I started off by drawing an outline of the cat and began to name the various muscles.

The other students in the class interrupt me: “We know all that!”

“Oh,” I say, “you do? Then no wonder I can catch up with you so fast after you’ve had four years of biology.” They had wasted all their time memorizing stuff like that, when it could be looked up in fifteen minutes.

Reliance on the memorisation of facts in preference to the more useful skills of knowing how and where to find facts and how to synthesise facts into useful knowledge is a common criticism of the education system here in the UK, and in the US as well. Facts are useless in and of themselves; as such, we’d be better off reassessing the way we teach kids than angsting over the results of the current (broken) system. As Carr points out, the connections we make between facts are the true knowledge, but he discounts those connections as soon as they are made or stored in the cultural sphere rather than the individual mind. That’s a very hierarchical philosophy of knowledge… which might explain Carr’s instinctive flinching from the ad hoc and rhizomatic structure of knowledge as stored on the internet. Don’t panic, Nick; the libraries aren’t going to get rid of the reassuringly pyramidal cataloguing systems any time soon. (Though I wish more of them would allow folksonomy tagging on their catalogue interfaces; best of both approaches, you dig?)

Another of the more persistent Rejectionista riffs is on the rise again, courtesy of Eli Pariser’s new book, The Filter Bubble. You know the one: confirmation bias! The internet makes it way too easy to ignore dissenting viewpoints! OMG terrible and worsening partisan schism in mass culture! (I have to admit that I suspect this riff is a symptom of continued American soulsearching about the increasing polarity of the political sphere; it’s a genuine and increasingly worrying problem, but it ain’t the fault of the intermatubes.)

There are numerous lionisings of and rebuttals to Pariser, if you care to Google them – amazingly enough, and very contrary to Pariser’s own thesis, both types of response appear in the same search for his name… even when searching using my Google account with its heavily customised results!. But I’ll leave you with some chunks from Jesse Walker’s riposte at Reason, which I found via Roderick T Long:

Pariser’s picture is wrong, but a lot of his details are accurate. Facebook’s algorithms do determine which of your friends’ status updates show up in your news feed, and the site goes out of its way to make it difficult to alter or remove those filters. Google does track the things we search for and click on, and it does use that data to shape our subsequent search results. (Some of Pariser’s critics have pointed out that you can turn off Google’s filters fairly easily. This is true, and Pariser should have mentioned it, but in itself it doesn’t invalidate his point. Since his argument is that blinders are being imposed without most people’s knowledge, it doesn’t help much to say that you can avoid them if you know they’re there.)

It is certainly appropriate to look into how these new intermediaries influence our Internet experiences, and there are perfectly legitimate criticisms to be made of their workings. One reason I spend far less time on Facebook than I used to is because I’m tired of the site’s hamfisted efforts to guess what will interest me and to edit my news feed accordingly. Of course, that isn’t a case of personalization gone too far; it’s a case of a company thatwon’t let me personalize as I please.

[…]

Pariser contrasts the age of personalization with the days of the mass audience, when editors could ensure that the stories we needed to know were mixed in with the stories we really wanted to read. Set aside the issue (which Pariser acknowledges) of how good the editors’ judgment actually was; we’ll stipulate that newspapers and newscasters ran reports on worthy but unsexy subjects. Pariser doesn’t do the obvious next step, which is to look into how much people paid attention to those extra stories in the old days and how much they informally personalized their news intake by skipping subjects that didn’t interest them. Nor does he demonstrate what portion of the average Web surfer’s media diet such subjects constitute now. Nor does he look at how many significant stories that didn’t get play in the old days now have a foothold online. If you assume that a centralized authority (i.e., an editor) will do a better job of selecting the day’s most important stories than the messy, bottom-up process that is a social media feed, then you might conclude that those reports will receive less attention now than before. But barring concrete data, that’s all you have to go by: an assumption.

And in that paragraph I think we see the reason that Rejectionistas like Carr and Pariser get so many column-inches in mainstream media outlets in which to handwring: because the editors who give them the space still feel that filtering is something that they should be doing on behalf of their readers, who are surely too stupid to chose the right things.

Given current newsworthy events, I think that’s an attitude which – no matter how well-meaning – needs to be challenged more, not less; if the choice is between applying my own filters or allowing someone whose motivations are at best opaque and at worst Machiavellian and manipulative to do the filtering for me, well… you’ll be able to find me in my filter bubble.

Don’t worry, I’ll see you when you arrive; its walls are largely transparent. Believe it or not, some of us actually prefer it that way. 😉


Bill C’s Ministry Of Truthiness

Paul Raven @ 18-05-2011

You must have seen this one already, but just in case: Bill Clinton raises the idea of independent “agency for truth” to counter all the misinformation on the intertubes [via everywhere, but I got it from TechDirt].

The agency, Clinton said, would “have to be totally transparent about where the money came from” and would have to be “independent” because “if it’s a government agency in a traditional sense, it would have no credibility whatever, particularly with a lot of the people who are most active on the internet.”

“Let’s say the U.S. did it, it would have to be an independent federal agency that no president could countermand or anything else because people wouldn’t think you were just censoring the news and giving a different falsehood out,” Clinton said.

“That is, it would be like, I don’t know, National Public Radio or BBC or something like that, except it would have to be really independent and they would not express opinions, and their mandate would be narrowly confined to identifying relevant factual errors” he said. “And also, they would also have to have citations so that they could be checked in case they made a mistake. Somebody needs to be doing it, and maybe it’s a worthy expenditure of taxpayer money.”

Hmmm. File under “nice idea, but naive and completely impractical given that the authoritarian approach to truth is antithetical to the way the internet works”. Heck, you could make it as transparent as spun diamond, and there’d still be conspiracy theorists claiming that the secret chains of funding and misinformation were just brilliantly concealed. It’s a tricky post-modern conundrum which I suspect will only ever be solved some sort of universal realisation that checking things out for yourself is the route to the truth.

Which is to say it’ll probably never be solved at all for most people. Selah.

That said, this totally merits the use of a classic macro:

Indeed.


The kids are, contrary to media coverage, all right

Paul Raven @ 03-09-2010

Why are there so many negative stories about teenagers in the media? Because that’s what older folk like to read.

Silvia Knobloch-Westerwick of Ohio State University gave 276 volunteers an online magazine to browse. She found that older people preferred to read negative news about young people, rather than positive news. What’s more, those older readers who choose to read negative stories about young individuals receive a small boost to their self-esteem as a result. Younger readers, in contrast, prefer not to read about older people at all.

[…]

We gravitate towards information that confirms our opinions, and tend to avoid that which will undermine or challenge us. It is just one of the many examples of cognitive biases at play in decision-making and judgment. Having our prejudices confirmed makes us feel better about ourselves, that is why we get the gleeful urge to say “I told you so”. This study may be most revealing because it does not demonstrate a general schadenfreude, but a one-directional, specific effect that should give us pause to think about the media’s coverage of young people.

It’s confirmation bias all the way down!


Gonzo Augmented Reality

Paul Raven @ 07-07-2010

Thomas Carpenter of Games Alfresco was pretty impressed by the AR app that superimposes an oil slick on any BP logo within the frame of its image capture, and started riffing on the idea of gonzo AR – a sort of “the world as seen by [x]” idea, taking the idea of reality being defined by personal perceptions right down to the granular level of individuals.

An unofficial game of object-association could make great interactive art, political rhetoric, or dystopic reinforcing world-view; depending on its implementation.  Wouldn’t you like to point your smartphone at everyday objects and find out how your favorite artists or celebrities view the world? Seeing how YoYo Ma, or the Dalai Lama or Bruce Campbell (the guy from the Evil Dead series) view the world could be liberating. Or since our own Bruce Sterling is the Prophet of AR, one of the AR browsers could do a “Bruce Layer” and show us what kind of world he sees when he’s looking around.

Maybe if Glenn Beck was your thing, you’d have a Nazi symbol pop-up when you pointed it at an Obama sticker.  Or if you were a former Bush-hater, you could see a Stalin-esque version of the W with your smartphone.   Propaganda could be all encompassing, blotting out all but the sanctioned viewpoints.

I think we can safely assume that AR (like any other media) will get pretty ugly when mainstream politics gets a hold of it… although, going on past form, that’ll probably happen a few years after everyone else has moved on to something more novel. Back to Mr Carpenter:

And maybe that’s what a gonzo-reality could bring to AR.  Instead of a mirror reflecting all of our beliefs into an ever-increasing sine wave, we might be privy to alternate views to our own.  Maybe even trying out how someone else sees the world.

Maybe.

Or maybe we couldn’t handle their viewpoint.  The overstimulating rush would make our realities spin around us until we puked it back out, losing all those alternate nutrients our world views could have used to grow.

And there you have it; new technology, same old spectre of confirmation bias. Still, if AR ends up as ubiquitous and packed with stuff as the existing internet, cognitive bias will at least be a whole lot of fun.


UFO sightings coincide with UFO movies

Paul Raven @ 21-08-2009

flying saucersVia Futurismic‘s long-term good buddy Mac Tonnies come the results of an analysis of the UK MoD’s “x-files” documents, recently released to public scrutiny; apparently UFO sightings were more common around the times at which popular films or television shows featuring alien races or spacecraft were screened. [image by eek the cat]

The obvious conclusion here is “well, skiffy movies cause alien sightings; case closed”. But as Mac points out, that’s not logically sound:

There’s doubtlessly a correlation between science fiction and UFO reports. But while pop culture’s influence on potential UFO observers is a fascinating subject with important sociological ramifications, to flaunt Clarke’s findings as a refutation of the phenomenon in general is to willfully ignore the evidence in its entirety.

UFO researchers aren’t interested in “noise” cases — the inevitable false alarms that plague efforts to study the phenomenon (whatever its origin). Indeed, scientists who have addressed the UFO problem have always been painfully aware of the disproportionately high volume of false returns.

Now, you may more skeptical than Mac regarding the causes of UFO sightings, but his point still stands – divorce the logic from the specific subject matter, and the same applies to any sort of genuine scientific enquiry. I’m pretty sure this is what they call confirmation bias at work, and it makes me wonder how often it affects us…

… although it obviously happens often enough for it to be politically useful. 😉
