my new favorite toy

Santa came early this year, pointing me to Gapminder, where international development geeks can visualize global economic and social trends til the heifers come home.

But it can also be fun for Ameri-centric users like me who are idly curious about, say, the average age women married in the US since 1800 or how much Americans drink compared to others...

To play too, be sure to click "visualize" next to your favorite indicators and then "play" the timeline. Enjoy!

curmudgeons for democracy

Popular dissatisfaction with government is usually taken as a sign that democracy is dysfunctional.

But a new study by Edward Miguel and his colleagues, as he reports in Foreign Affairs, suggests just the opposite; critical citizens are the foundation of democratic government.

Miguel was trying to figure out what might be the connection between education and levels of democracy in developing nations. (Even though there's a correlation between the two, no one agrees if what the causal link is between the two - if any.) His research team set up a randomized study, giving education incentives to one a set of girls schools in Kenya, leaving another set with no incentives. After a number of years and a clear increase in test scores at the first set of schools, they went in to see how the young women's political attitudes may have differed. Most of the obvious assumptions didn't pan out: the better educated girls were not more pro-democratic and neither were they more likely to vote or be involved in civic organizations. There was one difference: they were more critical of their government.

The study of course didn't find (or even search for) evidence to demonstrate the other half of the causal link - that is, that more critical citizens are more likely to bolster democracy - but it makes intuitive sense and is fodder for more research. At a very basic level, citizens who don't question their government aren't going to push for any change, let alone democratic change. Of course, more than dissatisfaction is needed to propel people to become politically active (usually those characteristics are bundled together into what social thinkers call "political capital"). And, of course again, too much dissatisfaction can lead to complete disaffection (of the Ted Kazcinski or couch-potato variety). But Miguel's experiment is a good reminder to us in old, creaking democracies that a critical citizenry should never be wished away.

The latest gems from Kevin Lewis' blog:

Love in the filter bubble?

Personalization algorithms already tell us what movies to watch, news stories to read and tunes to listen to. It was only a matter of time, then, that they’d tell us who to love.

Matching algorithms aren’t new to online dating services. EHarmony, Chemistry and OKCupid have long served up compatible mates based on dozens, if not hundreds, of questions singles answer on their sites.

But a new dating app, StreetSpark, is venturing out internet-wide to pick up clues on who you’re likely to become enamored with. Love seekers on the site can plug into their Facebook, Foursquare and Twitter accounts to discover potential lovers with similar tweets, profiles and cafe haunts. (That, at least, is the concept. So far this single has yet to be sent a match.)

It’s like “traditional” online personalization but in reverse. Instead of telling you what you’ll like based upon your friends’ preferences, it tells you who you’ll want to be friends with based on what you like.

StreetSpark touts their service as giving “serendipity a helping hand.” Normally we have to wait for luck to bring us face to face with that special someone; StreetSpark provides us with a helpful homing device right in our smartphone.

It’s an odd usage of “serendipity,” though, which describes the phenomenon of making desirable discoveries by accident. If you instruct your iPhone to tell you when there’s a sympatico mate in your hood, bumping into them can’t really be described as “an accident.” Of course, the makers of StreetSpark are aware of that contradiction and are tongue and cheek in using the term.

But it’s more than a semantic quibble. Part of appreciating the beauty of “making discoveries by accident” is to understand that sometimes we don’t know what we’re looking for. If you’re a romantic, that can especially be true in the case of love. It’s not as if we have the profile of “the perfect guy” in our head and falling in love is just a matter of luck when you’ll run into that profile. The “accident” of love is when we meet someone who doesn’t fit our pre-conceived ideal and yet, mysteriously, we fall head over heals. In the process, if we’re truly lucky, we’re opened up to a new, exciting and unknown world.

GOTV strategy: anger-mongering

The one thing more distressing than listening to politicians demonize their opponents as deliverers of doom and destruction - is to read a study on why it's such an effective strategy.

Why people bother to go out to the polls (when clearly their one vote counts so little) is a question that's been dogging political scientists for years. There are countless explanations for this quaint act of civic participation, many of which probably contribute to the full, true, picture. A big part of that picture is habit. Those of us who vote in our 30s, usually keep voting for the rest of our lives. But how does that habit start?

Anger is partly to blame (or credit, I suppose), according to a paper by Nicholas Valentino. Like fear, anger is a common response to perceived threats - aka Democrats who are going to turn America into a socialist state or Republicans who are conversely gunning for Fascism. Unlike fear, however, anger gets you into action; fear will instead keep you quaking in your boots (and staying home on election day).

Whether your response to political threats is anger or fear depends upon your sense of "internal efficacy" - that is, how "competent and influential" you think you are in the political sphere. Just as when someone pushes into you on the subway platform, depending upon their size and appearance - and thus your "competence" to deck them - will determine whether your response is anger or fear. (Yes, the question of makes one high or low on the "internal efficacy" continuum is not answered -but, really, we can only deal with one quandary at a time.)

In young people the effect of inciting anger can be quite effective - boosting political participation as much as 10%. Given that voting becomes a habit, getting young angry citizens to the polls can reap long-term benefits (like advertising Coke to 5 year olds).

That's bad news if, like me, you want to tamp down on angry rhetoric in politics. The small silver lining, however, is that inciting fear does not have similar results. Right now I need all the silver linings I can get.

In war we trust


There are countless academic and popular theories why Americans have such a dim view of their political leaders today. Most suggest a progressive decline in democracy - the rise of a 24/7 media culture dumbs down debate; a lack of campaign finance limits makes politicians beholden to special interests; 60s social welfare culture has made the state self-perpetually bloated; extreme partisanship has politicians more interested in winning than in solving problems, etc.

Two profs from Vanderbilt and University of Illinois, however, think things haven't really changed that much since the 60s. According to a paper by Marc Hetherington and Thomas Rudolph, government's doing as well (or poorly) as it ever has and citizens' views of government hasn't really changed over the decades.

So how do they explain the apparent decline in trust over the years? It's a question of salience - that is, what Americans happen to think is the most important issue at any given time.

As you might imagine, we tend to pay more attention to things that worry us. So when the economy is fine but we're worried about nuclear war with Russia, we think international issues are most pressing. But if inflation is spiking and jobs are thinning out, we'll turn our focus onto the economy.

Concerns about international vs. domestic troubles do not, however, have the same effect on our trust in government. Fear of foreign threats increases our faith in the state, while worries about problems at home decreases our trust. The reverse is also true - a peaceful globe makes us less beholden to our state and a booming economy keeps us content with government - but the effect is not as strong. That leaves us with the following picture:


When attention on the economy or crime increases (the 70s and early 90s), political trust decreases. Even more clearly, eyes on international issues (60s, mid-80s and 9/11) boosts confidence in government. Today, with 9/11 faded in our memories and the economy teetering on double-dip recession, it makes sense that we distrust government more than ever.

More political behavior highlights from Kevin Lewis' blog:

Select your 150 friends wisely

Online technol0gy is transformative. It can make the world flat, spark revolutions and even wrap us into personalized filter bubbles. But there’s one thing technology hasn’t been able to do yet: expand our circle of friends.

You’re probably familiar with Dunbar’s “150 rule:” the reason that humans tend to limit the size of their communities to 150 people – whether in prehistoric towns, in military units or in cults – is because the human brain maxes out at 15o friends.

Now it turns out that even Twitter can’t free us of this 150 ceiling. Bruno Concalves and colleagues at Indiana U recently looked at 1.7 million tweeters over 6 months to see how many connections they kept up (connections, as opposed to mere followers, had actual back-and-forth exchanges). True to Dunbar’s prediction, twits generally don’t maintain more than 100-200 friends.

That’s bad news for the filter bubble. You can imagine one hope of avoiding a personalized information bubble is to widen your circle of friends in order to include folks with different viewpoints. That way you might expand the information that arrives on your laptop screen. But, as Eli points out in the intro to his book, merely adding friends to your FaceBook list doesn’t mean you’ll interact with them. No interaction means those “friends” will be virtually invisible on your feed. You’re still stuck in a community of 150.

The only way to truly escape the bubble may be to replace some of your current connections with people who disagree with you – and actually engage them in discussion. Of course, if we’re concerned about the limitations of human behavior, that may be the most pollyanish hope of all.

Filtering ourselves by eyewear

Personalization algorithms, especially those that factor in our friends’ preferences, have a way of clumping us into ever more homogeneous and like-minded groups. That’s one of the central ideas of The Filter Bubble.

But, as Eli freely admits, online personalization is not the only force filtering out diversity and sieving in homogeneity. We humans are very good at sorting ourselves into groups that look and think much like ourselves – without the help of algorithms.

The power of homophily, the sociological term for our self-sorting tendencies, hardly needs scholarly backing ; just glancing around any college cafeteria should be enough to convince that we flock to birds of similar feathers. But that doesn’t stop academics from supplying hundreds of studies for evidence. In two such recent papers, researchers show the breadth and depth of our self-sorting behavior.

On the high-commitment end, we marry within our political party. That may not seem surprising, but when you compare it to a weaker tendency to marry people with similar personality traits, it suggests that for the most important decisions in life we value people who think like we do more than those who act like us.

At the other – superficial – extreme, we sit near people who look like us. Based on self reports and experiments, researched subjects tend to find seats next to people of the same gender, race, hair length, hair color and general attractiveness. And, yes, eyeglass wearers prefer sitting next to each other too.

feedback loop yourself into the person you want to be

Okay, this product may not turn me into the productive, well-toned and social person I want to be, but it's a start. Greengoose (still in production) uses sensors - on your toothbrush, water bottle and exercise gear - to track your healthy habits and then - and this is where the true genius is - turns them into points that you can use on Greengoose online games.

It's one of many products profiled at Wired, all of which use feedback loops to help you be that energy-conserving, financially responsible and fit person we all dream of being.

It's an article worth reading, but it misses one crucial point. Feedback certainly has an impact on moderating our behavior, but what makes Greengoose and the other products mentioned in the article so powerful is that the information they track enters the social sphere. In the case of Greengoose, that data gets turned into points that you can use to play games. For most of the other products, your information simply gets transmitted for others to see.

That's powerful stuff. We are social animals and our beliefs and behaviors are largely a product of those around us. Studies show that just by putting a picture of eyes on a computer screen, people are more likely to act ethically. So it's no wonder that making our daily habits public is the best bet for altering those habits.

Popping bubbles at MIT

Tyler Cowen thinks American innovation is in trouble.

At a TEDx talk two weeks ago he listed the causes of its demise, one being that American research and development is “tinkering with the parts not the whole.” There is “intensive innovation at the margins,” with experts refining the technological advances they know well. But few have the inclination or breadth to look across research fields and come up with entirely new technologies.

It’s a criticism that’s been leveled at university departments (with their academic fiefdoms) and, of course, which Eli sees happening more and more web-wide. As we nestle into our separate information enclaves, we’re missing the opportunities for insight and invention – whether in public policy, culture or innovation – that come from a broad perspective.

Worrisome. But MIT may have an antidote – at least when it comes to what’s ailing technological innovation.

As profiled by Ed Pilkington in the Guardian last month, MIT has long made a habit of pushing its faculty to cross academic boundaries – or disregard boundaries entirely – in order to explore ideas and inventions that may, at first glance, seem hair-brained or useless. That’s how composer and inventor Tod Machover could spend years tinkering with a “hyperinstrument” for Yo-Yo Ma, developing technologies that two of his students would eventually use to build Rock Band and Guitar Hero.

It’s more than just the gestalt of the place though. MIT actively encourages cross-discipline collaboration:

MIT delights in taking brilliant minds in vastly diverse disciplines and flinging them together. You can see that in its sparkling new David Koch Institute for Integrative Cancer Research, which brings scientists, engineers and clinicians under one roof. Or in its Energy Initiative, which acts as a bridge for MIT’s combined firepower across all its five schools, channelling huge resources into the search for a solution to global warming.

With all those big brains bouncing off each other, it comes as little surprise then that MIT’s alumni have gone on to found tech companies that now account for 1/7th of US GDP – and half the ventures in Silicon Valley.

But why is MIT’s kind of innovation not happening among business behemoths, who surely have the money to fund MIT type R&D?

Daron Acemoglu, economist and MIT luminary himself, has an answer. And it’s pretty simple (although he has pages of econo-math to prove it): research only pays if you can convert it into marketable innovations today. But truly earth-shifting discoveries and innovations usually take years – or sometimes centuries – before they can be translated into marketable products. That’s why, as Cowen says, in business innovations only happen at the tips of the branches. Sprouting new technological branches simply doesn’t pay off – even with 20-year patents.

Luckily MIT isn’t dependent upon immediate profit; instead, government funding heavily subsidizes its seemingly zany, boxless and even pointless research. But we all benefit – when that freedom to explore and collaborate turns into new businesses and jobs down the road.

Publicly subsidized research, of course, has always been recognized as key to national economic growth (unless you’re a strict libertarian). MIT just happens to be a particularly strong example of how those subsidies can foster cross-discipline innovation. The market, as Acemoglu explains, isn’t providing the incentives for ground-breaking research and collaboration – so the government needs to step in.

But what about when about the market doesn’t provide incentives for all of us to explore ideas that are new, outside our usual interests, or challenging to our current perspectives? What should be the government’s role when the market instead draws us into filter bubbles because, well, selling the familiar and habitual is more lucrative.

In his book, Eli shies away from government imposed responses to the Filter Bubble. It’s a wise caution; you want to be really careful when it comes to imposing state rules on information flows. But could we invent and subsidize an internet MIT, a place where it pays to look beyond your perspective, a counter-force to our filter bubbles? I have no idea what that would look like, but if an online venture could push us to challenge our views, explore new ideas and even learn about what is distasteful to us – I’d give my tax dollars to subsidize that check.

Genetically modified crowds

To anyone familiar with human stampedes, financial panics or professional soccer games, the “Wisdom of Crowds” may seem more like an oxymoron than a legitimate pursuit of study.

But as James Surowiecki so adeptly describes in his book of that name, crowds can be wise.

Under certain conditions. First, they must be diverse; homogeneous groups will be limited – or aggravated – by their shared narrow perspective. Next, groups must be set up so that individuals can think independently, thus avoiding the twin traps of groupthink and mis-information cascades. Finally, they have to have a way to aggregate their ideas, inputs and decisions.

Open source communities and (some) markets are good examples that meet all three conditions. Filter bubbles, which encourage homogeneity and cascades while eschewing communal aggregation, are not.

But if filter bubbles may make online communities stupid, could we make algorithms that make us collectively smarter?

We’re probably a long way off, but the Center for Collective Intelligence at MIT is at least moving in the direction. Led by Thomas Malone, the center is looking more deeply at the “DNA” of smart groups; how the “what, who, why and how” of a group correlates to group intelligence.

In a study published last year, Malone and his colleagues discovered that average intelligence, for one, does not predict group intelligence. Other factors, such as group cohesion, satisfaction and motivation, are only moderately correlated. What does make a group smarter? Having a few people who are “socially sensitive;” that is, members who tend to be more open and receptive.

Malone and his crew are taking results like that and mapping them onto a “genome” of group intelligence. Workplaces and organizations are taking note, but so are news sites and online government initiatives interested in harnessing the intelligence of readers and constituents. Have an under-producing team or a comment thread full of flamers? Time for some group dynamic gene-splicing.

It might be too far a reach to translate MIT’s work to the the group dynamics of the internet as a whole – at least in the near future. But perhaps one day we’ll be building algorithms to maximize collective intelligence rather than just personal relevance.

The creativity that cannot be bubble-wrapped

In spite of Eli’s and this blogger’s concern that filter bubbles could put a damper on innovation and creativity, there is one realm that is evidently immune to the filter: the humorous internet meme.

Whether photo-shopping, re-mixing, re-producing or auto-tuning, online denizens show no shortage of creativity in riffing off of each other and, to reference Arthur Koestler again, “bisociating” two ideas into new, clever, creations.

You’re no doubt familiar with the “Charlie Bit My Finger” phenomenon (if not, do a search and enjoy the hundreds – or thousands – of knock offs on the original home video sensation). I thank Michael Agger over at Slate for introducing me this morning to an endless trove of similar comic collaborations. Know Your Meme will chart you through the history of the Bed Intruder, the Double Rainbow, the Fashionable Chinese Bum, and countless others. (If you don’t want to waste hours of your day, do not check out Super Cut Movie Cliches.)

Perhaps the filter bubble can’t stifle humorous creativity precisely because, as Eli writes about, humor is one of the few things that manages to pierce our bubbles. If you glance at any “top emailed” or “most popular” list, you’re certain to see humorous articles and videos monopolizing the list. For anyone who’s spent more than an hour online, it’s almost not worth explaining why this is so. Who can resist an opportunity to laugh, whether it comes in the form of a forwarded email, a Facebook post or a link on our favorite online mag?

But should we be encouraged by the the penetrability of humor? Probably not. The darker side of humor is that it represents one the “junk foods” we do tend to feast off of online – along with gossip, cute animals, morally shocking news and, of course, porn. None of these items are likely to be slowed down by our filter bubbles. Not that there’s anything inherently wrong with that. But when Antoine Dodson is the one thing we’re sharing and collaborating on, it’s nothing to sing (or auto-tune) about.

The – true – Republic of Twitter

As has been mentioned before in this blog and in Eli’s book, the internet has not turned out to be the democratic utopia of information it was once hoped to be. If our information is not being piped through (albeit new) elite media hubs, then it is being filtered through the bubble of our and our friends’ preferences.

That’s at least the case for most of the internet. One exception, however, may be Twitter.

Unlike Facebook and Google, Twitter doesn’t make assumptions about the tweets you’d prefer to see. What you sign up for is what you get. It’s bubble-free media.

Twitter, new research suggests, may also be anti-elitist. We’ all know about the Ashton Kutchers and Old Spice Men of mega-twit fame. Turns out that, in spite of their gajillion followers, those Tweet Leviathans have little influence in spreading memes. Looking at 580 million tweets over 8 months and using some fancy statistical crunching, researchers found that mid-range tweeters (who have about 1,000 followers) are much more influential when it comes to creating and spreading hashtags.

Could that mean Twitter is indeed the democratic medium we’ve all been looking for? We don’t like to jump to conclusions based on one study (especially one with new-fangled statistical techniques), but the study’s findings temptingly align with the theory that on Twitter information roams free. (On an even more conjectural note, their research may also mean Twitter deserves credit on the “maximizing creativity by minimizing silos” front.)

The impressive research – which comes in two reports and which also tracked memes in stories longer than 140 characters – contains some other fun tidbits, although none directly relevant to the filter bubble. Of note:

  • Partly depending on whether memes (defined in longer stories as “short phrases”) started in mainstream news sites or blogs, they had disparate patterns of peaking and trothing online. (The researchers found 6 distinct patterns).
  • The influence of mainstream media v. blogs in spreading memes depends on the subject area. When it comes to Entertainment and Tech, for example, blogs rule.
  • Finally, don’t tell Bill Keller, but when comparing the influence of the New York Times, USA Today and the Wall Street Journal, USA Today wins out on every beat, except for National News where it is bested by WSJ. (Note: even the authors are surprised by these results.)

That other – imperfect – gatekeeper

The internet gave great hopes for the liberation of information. No longer controlled by elitist (or corporatist) editorial gatekeepers, now “all” the news (not just what was fit to print) could truly be accessible to the people. A new era of democratized media was dawning.

Well, that’s not exactly what happened. Writers like Evgeny Morozov point out that political power can still manipulate the internet to meet its ends. And as Eli discusses in The Filter Bubble, gatekeepers haven’t gone away – they’ve just been replaced with a new algorithmic breed, which bring their own set of concerns for democracy.

One of those concerns is what happens when the news we’re delivered is the news the personalized algorithms think we want. I’m a pretty worldly, news-savvy gal, but I admit that I can’t help clicking on those hat photos from the royal wedding or the latest gossip from Dancing with the Stars. If the personalization bots interpret those clicks as “Give the girl the fluff she wants”, how much more trash will be sent to tempt me – and how much “important” news will go missing from my news feeds?

As Eli puts it in his TED talk, the new gatekeepers may be turning us into junk-news gluttons. The old gate-keepers had their problems, but at least they made sure we got our news vegetables along with our dessert.

Or did they?

Today Slate reminded us that even our elitist of elite publishers can sideline the vegetables for sweeter fare. The day after the first GOP presidential debate of the 2012 campaign, an important marker in our political discourse, one would have thought the 4th Estate would have brought the event to our attention. Not so. The debate didn’t show up in print in the New York Times, Washington Post and Wall Street Journal until somewhere between pages A3-A19. What did make the front page? Stories about “Maryland basketball coach Gary Williams, Pippa Middleton, and UFO sightings in Thailand.”

Now, in the editors’ defense, it was a debate populated by few real contenders. But still. Pippa Middleton?

Of course, since the news giants lost their captive print audiences, they’ve been in the same race to the lowest common denominator as have the personalization algorithms. Perhaps the NYT, WaPo and WSJ of 1995 would have had the debate on the front page. Either way, when it comes to getting a balanced diet of food, today we may be all on our own.

Vampires, wizards and American identity

If you agree that having a common national identity is critical to a well-functioning democracy, filter bubbles may give you cause for concern.

Not that there’s anything wrong with sub-national identities. Since long before the days of Dixies and Yanks, America has been a vibrant mix of regional and sub-cultural identities. That’s a feature, not a bug.

But even as we self-sort and brand ourselves as Hipsters, Hip-Hop-sters, Christians, Vegans, Locovores, Nascars, etc. – Americans have shared a common narrative that’s lets us all, more or less, identify as “Americans” and work together when times get tough.

As filter bubbles draw us deeper into our sub-cultural silos and place a narrative wall around groups of Americans, however, that shared national identity could start to erode (if it hasn’t already).

The good and bad news is our sense of identity may be pretty malleable.


All it took was a little narrative. 140 undergrads sat down to read 30 minutes of either Twilight or Harry Potter and then take a couple of personality tests. Students who read Twilight were more likely to associate themselves with words like “blood, fangs, bitten, undead” and to say they had sharp teeth. The effect was even stronger for test subjects who were more group-oriented.

The bad news is that if we can identify with mythical creatures so easily, then it’s no surprise we readily take on the identities of humans in our narrow social networks.

The good news is that, as long as our filter bubbles let even drops of a common national narrative seep through (as it did this week with the OBL story), it might be enough for us to feel we’re still all “Americans.”

when seeing is mis-believing

Hampshire, England delivers a great example of confirmation bias - the phenomenon of seeing what you expect to see - in the shape of a stuffed tiger.
