Collective Memory and Culture

This is an interesting explanation of how digital networks affect culture.  Comments in RED.

How We’ll Forget John Lennon

Kevin Berger

A few years ago a student walked into the office of Cesar A. Hidalgo, director of the Collective Learning group at the MIT Media Lab. Hidalgo was listening to music and asked the student if she recognized the song. She wasn’t sure. “Is it Coldplay?” she asked. It was “Imagine” by John Lennon. Hidalgo took it in stride that his student didn’t recognize the song. As he explains in our interview below, he realized the song wasn’t from her generation. What struck Hidalgo, though, was the incident echoed a question that had long intrigued him, which was how music and movies and all the other things that once shone in popular culture faded like evening from public memory.

Hidalgo is among the premier data miners of the world’s collective history. With his MIT colleagues, he developed Pantheon, a dataset that ranks historical figures by popularity from 4000 B.C. to 2010. Aristotle and Plato snag the top spots. Jesus is third. It’s a highly addictive platform that allows you to search people, places, and occupations with a variety of parameters. Most famous tennis player of all time? That’s right, Frenchman Rene Lacoste, born in 1904. (Roger Federer places 20th.) Rankings are drawn from, essentially, Wikipedia biographies, notably ones in more than 25 different languages, and Wikipedia page views.

Medium Is the Message: “As a new medium takes over, the type of information being produced changes dramatically,” says Cesar Hidalgo. “Printing was not good for actors but good for playwrights. TV was not good for playwrights but very good for sports.” 

 In December 2018, Hidalgo and colleagues published a Nature paper that put his crafty data-mining talents to work on another question: How do people and products drift out of the cultural picture? They traced the fade-out of songs, movies, sports stars, patents, and scientific publications. They drew on data from sources such as Billboard, Spotify, IMDB, Wikipedia, the U.S. Patent and Trademark Office, and the American Physical Society, which has gathered information on physics articles from 1896 to 2016. Hidalgo’s team then designed mathematical models to calculate the rate of decline of the songs, people, and scientific papers.

The report, “The universal decay of collective memory and attention,” concludes that people and things are kept alive through “oral communication” from about five to 30 years. They then pass into written and online records, where they experience a slower, longer decline. The paper argues that people and things that make the rounds at the water cooler have a higher probability of settling into physical records. “Changes in communication technologies, such as the rise of the printing press, radio and television,” it says, affect our degree of attention, and all of our cultural products, from songs to scientific papers, “follow a universal decay function.”

Last week I caught up with Hidalgo to talk about his Nature paper. But I also wanted to push him to talk about what he saw between the mathematical lines, to wear the social scientist’s hat and reflect on the consequences of decay in collective memory.

How do you define “collective memory?”

The easiest definition would be those pieces of knowledge or information that are shared by a large number of people.

Why does collective memory decay matter?

If you think about it, culture and memory are the only things we have. We treasure cultural memory because we use that knowledge to build and produce everything we have around us. That knowledge is going to help us build the future and solve the problems we have yet to solve. If aliens come here and wave a magic wand and make everyone forget everything—our cars, buildings, bridges, airplanes, our power systems, and so forth, we would collapse as a society immediately.

The relative power of scientists has diminished as we exited the printing era and went into this more performance-based era.

In your mind, what is a classic example of collective memory decay?

I thought everybody knew “Imagine” by John Lennon. I’m almost 40 and my student was probably 20. But I realized “Imagine” is not as popular in her generation as it was in mine, and it was probably less popular in my generation than in the generation before. People have a finite capacity to remember things. There’s great competition for the content out there, and the number of people who know or remember something decays over time. There’s another example, of Elvis Presley memorabilia. People had bought Elvis memorabilia for years and it was collecting huge prices. Then all of a sudden the prices started to collapse. What happened is the people who collected Elvis memorabilia started to die. Their families were stuck with all of this Elvis stuff and trying to sell it. But all of the people who were buyers were also dying.

You write collective memory also reflects changes in communication technologies, such as the rise of the printing press, radio, and TV. How so?

Take print. Changing the world from an oral tradition to a written tradition provided a much better medium for data. A lot of people have linked the revolution in the sciences and astronomy to the rise of printing because astronomical tables, for instance, could be copied in a reliable way. Before printing, astronomical tables were hand-copied, which introduced errors that diminished the quality of the data. With printing, people had more reliable forms of data. We see very clearly from our data that with the rise of printing you get the rise of astronomers, mathematicians, and scientists. You also see a rise in composers because printing helps the transmission of sheet music. So when you look at people we remember most from the time when print first arose, you see ones from the arts and sciences.

What did the mediums that came next mean for science?

The new mediums of radio and TV were much more adaptive for entertainment than science, that’s for sure. The people who belong to the sciences, as a fraction of the people who became famous, diminished enormously during the 20th century. The new mediums were not good for the nuances that science demands. For good reason, scientists need to qualify their statements narrowly and be careful when they talk about causality. They need to be specific about the methods they use and the data they collect. All of those extensive nuances are hard to communicate in mediums that are good for entertainment and good for performance. So the relative power of scientists, or their position in society, have diminished as we exited the printing era and went into this more performance-based era.

At the same time, scientists and the general scientific community have not been great at adapting their ideas to new mediums. Scientists are the first ones to bring down another scientist who tries to popularize content in a way that would not be traditional. So scientists are their own worst enemies in this battle. They have lagged behind in their ability to learn how to use these mediums. Sometimes they focus too much on the content without paying attention on how to adapt it to the medium that will best help it get out.

What does your analysis tell us we didn’t know before about the decay of collective memory?

We began by looking at how popular something is today based on how long ago it became popular in the first place. The expectation is collective memory decays over time in a smooth pattern, that the more time goes by, the more things become forgotten. But what we found when we looked at cultural products—movies, songs, sports figures, patents, and science papers—was that decay is not smooth but has two defined regimes.                                                                                                                                                                                                                                                                                                                                                                                                                                                 Then there’s the second regime in which it has a much longer tail, when the decay is smoother, and the attention is less. [This implies that artistic innovation, which departs from the popular, will take longer and a more focused, or niche, audience to catch on; its durability and network dissemination determining how successful it is.] 

I’m surprised how the U.S., a country with people doing so many things, can become so monothematic on such a vast scale.

When we started to think about decay, we realized we could take two concepts from anthropology—“communicative memory” and “cultural memory.” Communicative memory arises from talking about things. Donald Trump is very much in our communicative memory now. You walk down the street and find people talking about Trump—Trump and tariffs, Trump and the trade war. But there’s going to be a point, 20 years in the future, in which he’s not going to be talked about every day. He’s going to exit from communicative memory and be part of cultural memory. And that’s the memory we sustain through records. Although the average amount of years that something remains in communicative memory varies—athletes last longer than songs, movies, and science papers, sometimes for a couple of decades—we found this same overall decay pattern in multiple cultural domains.

In your forthcoming paper, “How the medium shapes the message,” you refer to the late cultural critic Neil Postman who argued that the popular rise of TV led to a new reign of entertainment, which dumbed us down, because entertainment was best suited for TV. Is that what you found?

We found evidence in that favor, yes. Because the fraction of people who belong to the sciences, as a fraction of all of the people that become famous, diminishes enormously during the 20th century. It would completely agree with that observation.

Do you agree with Postman that we’re all “amusing ourselves to death?”

I don’t think we’re amusing ourselves to death. I’m not like that much of a pessimist. I do think life is also about enjoying the ride, not just about doing important things. And new mediums like TikTok, a kind of Twitter for videos, are great for creative expression. People are doing amazing little performance skits on TikTok. The entertainment and artistic components of every new medium are not bad per se, but every medium can be hijacked by extreme people who know how to craft entertaining messages, especially when they want to advance a certain agenda.

What type of information is best suited for the Internet?

It’s hard to think of the Internet as a medium. It’s more of a platform in which Facebook, Twitter, email, and TikTok are different mediums. They each send their own type of message. A picture that does well on Instagram doesn’t necessarily shine on Twitter, where people are expecting something else. The behavior and the engagements are different. Twitter, for example, is about being controversial. You know, one way to get chewed up on Twitter is to try to be in the center! I use Twitter a little, but not that much. I find that it’s a little bit hostile. I’m a family type of guy, so I use Facebook. In Facebook, at least in my circle, you put more detail into comments and are a little bit more thoughtful.

Now people like Elon Musk are in the center of culture. Young people now look up to entrepreneurs the way we used to look up to musicians.

Is collective memory decaying more rapidly because communication technologies are so much faster?

I would love to know that but I can’t. Some people would say collective memory decays based not on calendar time but the speed at which new content is being produced. We forget Elvis because the Beatles came up and we forget the Beatles because Led Zeppelin came and we forget Led Zeppelin because Metallica came up, and so forth. But things become very dear to a generation and people will not forget about them just because new content came in. So decay would be something characteristic of humans, not the volume of content. To separate those two things, we would need to look at content from very different time frames. At the moment, we don’t have the richness of data that we would need to answer that question.

Still, don’t you think the speed at which online information is tearing through our brains has got to be leaving some path of destruction in collective memory?

I don’t know. I grew up in Chile, which of course is small compared to the United States. I came to the U.S. for the first time in 1996. And one of the things that still surprises me is how monothematic American culture can be. In 1996 it was all about O.J. Simpson. Everybody talked about O.J. Simpson. He was everywhere on TV. Just like Trump today, he consumed the entire bandwidth. I’m surprised how a country with so many people, and with people doing so many different things, can nevertheless become so monothematic on such a vast scale. Today we have so much more content than in 1996 because of the rise of the Internet and the ability of people to create content. But look at the percentage of all conversations and online communications that are consumed by Trump. So in that context, I don’t think content is being replaced so easily. I don’t see that much of a rise in diversity. [This indicates the winner-take-all nature of network and popularity metrics. Content creators become famous for being famous.] 

That’s really interesting. Because one of the common criticisms of the current information glut is we have no shared cultural center. Everybody has their own narrow interest and we have no shared cultural bond, no John Lennon.

Is that a collective memory phenomenon or is it because nowadays the guys in the middle of the culture are different guys? Different people come into the center of culture because of the type of mediums that are available. There have been musicians for thousands of years, and for most of that history, musicians have not been wealthy. It was only when there was a medium that allowed them to sell their music—vinyl, magnetic tapes, and discs—that they were able to make money. I think that generated a golden era of pop music in the ’60s, ’70s, and ’80s. And that’s associative to a communication technology that was dominant at that time. Radio and discs were a way to distribute those popular idols’ musical performances. When that technology was replaced by simple forms of copying, like the ability to copy files on the Internet, all that went away. [This explains why the music industry of physical media, with its high-profit margins, is not coming back.] Now people like Elon Musk are in the center of culture. He’s not John Lennon. It’s a very different type of leadership, a different type of model for young people. But Musk’s first job was an online payment start-up. And I think a lot of young people now look up to entrepreneurs the way we used to look up to musicians.

Did you come away from your study with insights into what may or may not cause something to stick in collective memory?

I read a very good book recently called The Formula by Albert-Laszlo Barabas. He says you can equate quality and popularity in situations in which performance is clearly measurable. But in cases in which performance is not clearly measurable, you cannot equate popularity with quality. If you look at tennis players, you find tennis players who win tournaments and difficult games are more popular. So quality and fame are closely correlated in a field in which performance is measured as tightly as professional tennis players. As you move to things that are less quantifiable in terms of performance, like modern art [or music or books], your networks are going to be more important in determining popularity. [This is why we need a human social network that curates and filters subjective content.]

How should we think about quality in media content?

Well, I would say that collective memory decay is an important way to measure and think about quality. If you publish some clickbait that is popular in the beginning, that gets a lot of views in the first couple of days, but a year later, nobody looks at it, you have a good metric. The same is true if you publish a more thoughtful piece that might not be as popular in the beginning because it didn’t work as clickbait—it required more engagement from the readers—but keeps on building readers over time. So the differences in longevity are important metrics for quality. [So unless we have a dynamic social network that can curate subjective contents and filter it into its proper consumer niche, quality becomes an ignored step-child to the popularity of art.]

That goes back to a paper I did when I was an undergrad about the decay functions of attendance of movies. There were some movies that had a lot of box office revenue in the first week but then decayed really fast. And there were other movies that decayed more slowly. We created a model in which people would talk to each other [this is what happens with an OSN] and communicate information of the quality of the movie. And that model only had one parameter, which was how good was the movie was. So the quality of the movie would increase or decrease the probability that people would go watch it. We could then look at the curves and infer how good the movie was, based not on the total area it was shown, or on the total revenue, but on the shape of the curve. That was interesting because there were movies that were really bad like Tomb Raider, which at first was a box office success. But if you put it on our model, you would see that it was just hype, people watched it, hated the movie, and the curve decayed really fast.

Cultural innovation and quality depend on human curation of content and word of mouth through a social network.

Antitrust and Vampire Squids

The US government wants to break up Facebook. Good – it’s long overdue

The Guardian, December 11, 2020

This week the government filed a ground-breaking antitrust suit against Facebook, seeking to break up the corporation for monopolistic practices. The suit comes on the heels of a similar case against Google, as well as an aggressive Democrat-authored congressional report recommending taking apart not just Google and Facebook, but Apple and Amazon as well.

The evidence against Facebook seems overwhelming, with enforcers pointing to internal email conversations in which the CEO, Mark Zuckerberg, and his colleagues allegedly conspired to monopolize the social media space by buying rivals and stifling competitors. Proof of intent to violate antitrust law appears to be ample. Yet news articles covering the case describe it as “far from a slam dunk”, and competition law experts predict that enforcers will “face an uphill battle” in proving their claims.

Embedded in these muted words about the legal viability of the case is a political battle about the nature of economic power. Both antitrust suits are the result of a new movement of anti-monopoly scholars and advocates pushing to reform a heavily concentrated and misshapen American economy. Yet within the cocooned world of orthodox antitrust experts, there’s a suspicious lack of enthusiasm for breaking up Facebook, or any of the tech goliaths. Fiona Scott Morton, for instance, a former Obama enforcer and opinion leader at Yale, wrote last year that “break-ups are not a good solution to the economic harms created by large firms in this sector.” And last year the leading antitrust scholar Herb Hovenkamp argued that “breakup remedies are radical and they frequently have unintended consequences,” and warned that “Judges aren’t good at breaking up companies.”

In this formulation, break-ups are a legally difficult and flawed remedy, akin to amputating the leg of someone in need of a pedicure. Some politicians are still listening to these experts; Republican politicians have expressed skepticism at break-ups, but even the 2020 Democratic platform says that regulators should only consider breaking up corporations “as a last resort”. More than politicians, judges listen to these arguments, and rewrite antitrust law from the bench to make bringing monopolization cases and winning them – even when the evidence is overwhelming – far too expensive and difficult.

Such a situation is historically unusual. As the historian Richard John notes, America has a long history of breaking up big companies. Some of those broken-up entities include logging companies in Maine in the 1840s, Standard Oil in the 1910s, and AT&T in the 1980s. In fact, in 1961 the supreme court pronounced that breaking up companies has “been called the most important of antitrust remedies. It is simple, relatively easy to administer, and sure.”

So what explains this modern reluctance?

The standard account is that a group of libertarian law and economics scholars in and around the University of Chicago recentered antitrust in the 1970s. These men, led by Milton Friedman, Robert Bork and George Stigler, sought to attack the New Deal regulatory state, and free concentrated capital. Bork led the legal crusade against what he called the “militant ideology” of aggressive antitrust enforcers. His goal was to pull control of this area of law out of the hands of liberal legislative bodies and place it in the hands of highly technical conservative economists and lifetime-appointed judges who would listen to them. When Ronald Reagan became president, he radically narrowed antitrust, amounting to what Bork called a “revolution in a major American policy”.

But this is only part of the story. It fails to explain how, in 2004, Antonin Scalia convinced his fellow supreme court justices, including Stephen Breyer and Ruth Bader Ginsburg, to join him in a unanimous supreme court decision which undermined the ability to bring monopolization cases by holding that the “charging of monopoly prices is not only not unlawful, it is an important element of the free-market system.

The liberal justices were swayed by a different set of scholars, less-well known in the revolution that has produced today’s monopoly-heavy economy. These scholars challenged Bork-influenced libertarians over certain methodological questions but accepted the ideological contention that antitrust should be a technical area without broader democratic goals.

This group is led by Hovenkamp, an academic centrist technocrat, who is the most important antitrust thinker alive today, nicknamed the “dean of the antitrust bar”. His partnership with Lyndon Johnson’s antitrust chief Don Turner and Harvard scholar Phil Areeda on a key antitrust treatise set the stage for his intellectual dominance in the 1980s. Stephen Breyer, a liberal justice and an adherent of Hovenkamp, once noted that advocates would rather have “two paragraphs of [the] treatise on their side than three courts of appeals or four supreme court justices.” Breyer wasn’t understating the point; to date, Hovenkamp has been cited by our highest court in 38 different cases, far more often than Bork.

Hovenkamp is an intellectual historian by training, and his views on antitrust policy are situated in a misleading narrative. His research radically downplays the historical importance of legislative and social movements focused on the democratic need to control big business, and instead emphasizes the role economists and technocrats began to play in shaping the law during the Gilded Age. As part of this narrative, he peddles an incomplete account of the origin of the Sherman Antitrust Act of 1890, the most important piece of anti-monopoly legislation ever enacted by Congress. Hovenkamp argues that there is no evidence that the framers of the Sherman Act sought to curtail monopolies brought about as a result of “superior skill or industry”. According to Hovenkamp, US Congress – and by extension Americans in general – never had a problem with big corporations, or even monopolies; we just didn’t like it when those monopolies became predatory.

This elitist and technocratic framework glosses over our rich anti-monopoly tradition. Thomas Jefferson, James Madison and Frederick Douglass all opposed monopolies on political grounds, and state legislatures in the 19th century began breaking up companies almost as soon as they started issuing corporate charters. Senator Sherman himself explained that the purpose of the federal antitrust act was “to put an end to great aggregations of capital because of the helplessness of the individual before them.”

Judge Learned Hand, whose decisions in contract and corporate law are still read with reverence, laid out the basic federal antitrust framework which was endorsed by the supreme court in 1946 and 1968 and governed our economy for most of the 20th century. In mandating the breakup of the aluminum monopoly of Alcoa in 1945, Hand concluded that monopoly power, in and of itself, was illegal. He explained that the Sherman Act is a law prohibiting monopolies, full stop, no matter whether they are predatory. He pointed out that Congress updated the antitrust laws four times in the 20th century to hit back at courts who attempted to narrow them.

Antitrust theory is dominated by reactionary yet often wildly inconsistent thinkers. Hovenkamp, who for decades resisted any action to rein in large technology firms, argued a year ago that breaking up these giants would send the economy back to “the Stone Age”. This week, reversing his position, Hovenkamp conceded that breaking up Facebook is now warranted – revealing his entire school of thought as largely a reactionary force torn between bending to concentrated financial power and scandalous headlines of abusive market power.

It is encouraging that the government is seeking to break up Google and Facebook, and that policymakers are rejecting flawed legal theorizing. But the resistance to restoring our anti-monopoly tradition runs much deeper than Robert Bork and his rightwing legacy. As we’ve seen, it’s just as entrenched within the centrist academic and judicial citadels of well-meaning technocrats who carry a deeply ingrained fear of too much democratic influence over the economy.

Policymakers and judges are going to have to shake off the misleading narrative spun by the current antitrust establishment. Doing so is essential not only for supporting fair markets, but for preserving democracy itself.

Competition is essential, which requires open access to markets and transparency.

Imagination and Creativity

Nice article on Ray Bradbury.

In an interview with James Day, Bradbury said imagining, or “fantasizing” as he put it, was essential to survive and grow. The most important part of a child’s day was the time right before he went to sleep, when his imagination received the whole range of his mind, allowing him to dream himself into becoming something.

Imagination didn’t simply help the person who imagined. Imagination was a line of dominoes, which, once activated, would set off a chain reaction that could inspire who knows who or how many people.

Man requires art. …not only because art can address the problems politics can’t, such as problems of the soul (see Bradbury’s story “A Piece of Wood”), but also because art, in a real way, strips away the material to reveal the real.

At tuka, we fully agree that to create, share, and connect with others using our imaginations and our artistic expressions is to fully realize our potential and who we are as human beings.

All we need is the right playground…

Streaming and Skimming

The argument here is really about product flow vs. art. According to Spotify, the quality of artistic expression is not what’s important to listeners, it’s all about the product flow. An oversupply of crap is still, well, crap. Spotify needs data, not music. They want to use musicians to mine their data network value to justify their share price.

Streaming services as distribution networks are not friends to artists.
