Retro Reviews: The Fisher King - or, to find the Holy Grail, unplug!

Lately, I've found myself rereading Arthurian myths and re-watching old movies inspired by the Quest for the Holy Grail.  Some of my favorite Grail films include Excalibur, Indiana Jones and the Last Crusade, and (that's right) Monty Python and the Holy Grail.  In this genre, there's an underrated classic I must mention: The Fisher King.  The fact that this 1991 comedy stars Jeff Bridges and Robin Williams is reason enough to watch it, but it's also a relevant movie for today.

In The Fisher King, Bridges plays Jack, a narcissistic radio jock who makes a living spewing inflammatory comments on air.  His sensationalism puts him on top of the world (financially speaking) ... until, one day, his caustic rhetoric provokes a mentally unstable listener to go on a mass shooting.  With his reputation destroyed and soul weighed down by guilt, Jack becomes a depressed, drunken fool.  He tries to work in a video store owned by his girlfriend, but he grows more and more miserable, wondering the streets and contemplating suicide.

One evening, Jack meets Parryplayed by Williamsa homeless man who believes he's one of King Arthur's Knights of the Round Table (ostensibly Parzival).  Jack learns that Parry was once a married man whose real name was Henry.  Tragically, Henry's wife was killed by the mass shooter that Jack provoked on air.  Traumatized by his wife's death, Henry fell into a delusional state of mind and became Parry.

Moved by pity and the chance for redemption, Jack helps Parry by setting him up with a new love: a reticent lady by the name of Lydia.  What follows is a series of hilarious yet charming scenes, including an awkward serenade and a clumsy dinner date.  Despite the gaucherie of their rendezvous, Parry and Lydia hit it off and fall in love.

Then three mythic themes of the Grail Quest play out: The Red Knight, the Holy Grail, and The Fisher King.  First, Parry finds himself facing 'The Red Knight' (a hallucination symbolizing the trauma of his wife's death).  As a result, he collapses and falls into a catatonic state.

Next, to wake him up, Jack realizes he must find 'The Holy Grail' (a random trophy in a castle-like building).  Finally, while on this Grail Quest, Jack fortuitously saves 'The Fisher King' (he trips the alarm in the castle-like building while swiping the trophy, which stops an old man from committing suicide).  When Jack delivers the Grail to Parry, Parry awakens in full consciousness and reunites with Lydia.  As for Jack, he almost relapses to his former talk-radio persona, but after another crisis of conscience, he leaves talk radio behind, finds his girlfriend, and confesses his love for her.

I said The Fisher King is relevant today, but why?  As the film points out, talk radio is sensational media that pits people against peoplecranks vs. hipsters, conservatives vs. liberals, etc.  In the book Understanding Media, Marshall McLuhan wrote that broadcasting opinion over radio was like beating a "tribal drum."  Presently, this tribalism has gotten worse with cable television and social media, which have fashioned echo chambers for partisan excess and fake news.

It's as if The Fisher King prophesied how the tribalism of electronic media would become unhealthy and destructive.  However, the movie also gives us a creative alternative: The Grail Quest, which symbolizes the search for a more authentic way of being in the world.  To get there, we may need to unplug from our electronics and interact the old-fashioned way: person-to-person, not running from trauma or tragedy but meeting it face-to-face, in fortitude and love.

The Science of Expertise: Book Review of Peak


(Image from Amazon)

Anders Ericsson is a psychologist who studies how people acquire expertise (notice I say "expertise" and not "talent"--we'll soon see why).  Basically, he's an expert on being an expert.  In his book written with Robert Pool, a mathematician and science writer, he makes the following claim about what it takes to become an expert in just about any field: deliberate practice, and not innate talent.

This book includes stories about all kinds of experts: chess masters, sports stars, and whiz kids with extraordinary memory (for example, Rajveer Meena memorized the first 70,000 digits of pi, which took him over nine hours to recite).

My favorite story in the book, however, is the legend of Mozart. 

Mozart's musical skills: a question of talent or practice?

According to some biographies, Mozart composed music at age six and produced piano concertos by age eleven!  Was he a child prodigy due to innate talent, or was he just a hard worker?  Consider these facts:
  • First, it's an overstatement that Mozart composed at age six.  Historians have shown that his early compositions are in his father's handwriting.  So it's unclear that this work was entirely Mozart's.
  • Second, musicologists have shown that the piano concertos Mozart composed later, at age eleven, were based on sonatas written by other musicians.  Mozart's father probably assigned them to Mozart as compositional exercises.
  • Third, Mozart's father was an advocate for teaching music to children.  In fact, he wrote a book about teaching music to youngsters, and he tested his ideas on other kids (including Mozart's older sister).  Using refined teaching methods, he taught Mozart how to play, analyze, and write music.

Given these facts, Ericsson and Pool conclude: Mozart was skilled because he practiced, not because he was talented.
So we have no solid evidence that he did compose any significant music on his own before he was a teenager, and good reason to believe he did not.  And when he did unequivocally begin to compose music that was original and sophisticated, he had been training to compose for a decade or so.  In short, while there is no doubt that Mozart would become an extraordinary musician and composer, there is no evidence for--and plenty of evidence against--the claim that he was a prodigy whose accomplishments cannot be understood as the result of practice and must therefore be attributed to innate talent (214).
Practice (not Talent) creates Skill

The moral, according to Ericsson and Pool, is that it's mostly practice that makes us skilled performers, not talent:
while innate characteristics may influence performance among those who are just learning a new skill or ability, the degree and the effectiveness of training plays a more significant role in determining who excels among those who have worked to develop a skill.  This is because, ultimately, the body's and the brain's neural ability to adapt in the face of challenges outweighs any genetic difference that may, in the beginning, give some people an advantage (238).
Deliberate Practice and the 3 Fs

However, practice has to be deliberate.  Deliberate practice means developing skills based on proven training techniques.  It's deliberate because it requires focus, tweaks specific skills through targeted feedback, and allow you to fix mistakes.
Focus.  Feedback.  Fix it.  Break the skill down into components that you can do repeatedly and analyze effectively, determine your weakness, and figure out ways to address them (159).
What about Creativity?

Without these three Fs, you also cannot have creativity.
Furthermore, research on the most successful creative people in various fields, particularly in science, finds that creativity goes hand in hand with the ability to work hard and maintain focus over long stretches of time--exactly the ingredients of deliberate practice that produced their expert abilities in the first place (205).
How to Stay Motivated

Of course, deliberate practice is hard work!  If you want to be a skilled, creative expert, how do you stay motivated?

First, Ericsson and Pool suggest, set a schedule:
set aside a fixed time to practice that has been cleared of all other obligations and distractions (169).
Next, don't forget to be social, since others can help you stay motivated.
One of the best ways to create and sustain social motivation is to surround yourself with people who will encourage and support and challenge you in your endeavors (174).

Experts vs. Charlatans

Today we're seeing a public crisis: a distrust of experts.  That's a shame, because we need experts, including scientists and professionals.  Part of the problem is a failure of our media to distinguish experts from charlatans.  Ericsson and Pool can help us make this distinction.  Experts have deeply developed skills based on deliberate practice.  Charlatans only possess surface-level understanding, which isn't based on real-world experience (instead, it's based on badly written textbooks, Internet memes, hearsay, etc).

Is Big Tech an Existential Threat?

(Image from Amazon)

Journalist Franklin Foer recently wrote a book that takes big tech companies to task.  He singles out Google, Facebook, and Amazon, calling them existential threats.  Hence, the title of his book: World Without Mind: The Existential Threat of Big Tech.

Why does Foer refer to Google, Facebook, and Amazon as existential threats?  He gives many reasons over 250-something pages, but here are three themes I thought I'd highlight from his book.

Power vs. Privacy

One reason is that these companies have amassed a lot of economic power over our data—too much power.  As a result, only a handful of corporations (Google, Facebook, and Amazon, in addition to Twitter, Apple, and Microsoft) control nearly all of our personal information.  Foer calls them “monopolies” (although technically, the correct term is “oligopoly”).

For our own protection, Foer recommends regulating big tech as trustees of our data, subject to the same privacy protection laws and standards that other media corporations must adhere to.

It's worth quoting Foer on this point:

It’s a basic, intuitive right, worthy of enshrinement: Citizens, not the corporations that stealthily track them, should own their own data.  The law should demand that these companies treat this data with the greatest care, because it doesn’t belong to them.  Possessing our data is a heavy responsibility that must come with ethical obligations.  The American government has a special category for corporations that profit from goods that they don’t truly own: We call them trustees.  This is how the government treats radio and television broadcasters.  These companies make money from their use of public airwaves, so the government requires that these broadcasters adhere to a raft of standards (201).

The poverty of attention

Another reason big tech is an existential threat is that social media and digital technologies have serious psychological consequences with respect to our mental wellbeing: too much time with them kills our ability to provide sustained attention and focus.  Again, to quote Foer:

This abundance of free material, however, created a new form of scarcity—with so much to read, see, and hear, with the unending web of links, it became almost impossible to grab an audience’s attention.  David Foster Wallace called the condition Total Noise.  With it, our reading became peripatetic, less focused.  Back in the seventies, Herbert Simon, the Nobel-winning economist, took these inchoate sentiments and explained them rigorously: “What information consumes is rather obvious.  It consumes the attention of its recipients.  Hence a wealth of information creates a poverty of attention.”  The poverty of attention, the inability to hold a reader’s attention for sustained time, that’s the crucial concept (88).

The threat to civic dialogue

Just as attention and focus suffer, so too does our capacity to engage in civic dialogue.  That's because platforms like Facebook aren't designed to expand our minds.  Quite the opposite.  The algorithms are designed to seal us inside information bubbles.  To quote Foer once more,

Facebook’s algorithms supply us with the material that we like to read and will feel moved to share.  It’s not hard to see the intellectual and political perils of this impulse.  The algorithms unwittingly supply readers with texts and videos that merely confirm deeply felt beliefs and biases; the algorithms suppress contrary opinions that might agitate a user.  Liberals are deluged with liberal opinions; vegetarians are presented with endless vegetarians agitprop; the alt-right is fed alt-right garbage; and so on.  Facebook shields us from the sort of challenging disagreement—although not from the idiocy of trolls and the blather of comments sections—that might change our minds or help us to better understand the views of our fellow citizens.
In economics, the peril of the network is monopoly—where a competitive market comes under the sway of big corporations.  In culture, the peril of the network is conformism—where a competitive marketplace of ideas ceases to be so competitive, where the emphasis shifts to consensus (177-178).

An existential threat, really?

Is Foer right that big tech is an existential threat?

I admit, I'm sympathetic to Foer's point of view, even if his premise is a bit hyperbolic.  His points about privacy, mental health, and civic dialogue are entirely valid.  For those reasons, World Without Mind is definitely a book I'd recommend, especially for those who would like to challenge their assumptions about technological progress.

And now for something completely different: thoughts on The Last Jedi

Remember how Monty Python's Flying Circus used to begin?  "And now for something completely different."

That line might as well have been the opener for the latest installment in the Star Wars franchise: The Last Jedi.  (Warning: spoilers ahead if you haven't seen the movie yet.)  From Luke Skywalker chucking his historic lightsaber off a cliff to Supreme Leader Snoke getting sliced in half in what seemed like a total fluke, the film was so shockingly different that, honestly, I wasn't sure what to think at first.

The Last Jedi split the Star Wars fan base, with some petitioning Disney to remake the film.  Eventually, like our space heroes, we have to choose sides, and I'm going to take the side of defending the movie.  To do so, I'd like to address a couple common criticisms of the film: the subplot with Poe, Rose, and Finn was pointless; and Luke was way out of character.  Let's start with Poe, Rose, and Finn.

(Image from IMDb)

(Image from IMDb)

Nothingliterally nothingin their adventure went right.  So was their subplot pointless?  Yes.  But that was the point!  The old way of doing things is now obsolete.  This outdated MO includes triggering mutiny (Poe's insurrection against Resistance leaders), going rogue (Rose ditching her post to help Finn and Poe), and launching an all-out offensive with no real plan (Finn's failed kamikaze move).

As any team strategist knows, sometimes you need to play defense, and hold the offense for later.  Poe finally learns this lesson when he understands the evacuation plan his leaders were trying to execute, and Finn learns the same from Rose when she says, "We're going to win this war not by fighting what we hate, but by saving what we love."  With that lesson learned, let's talk about Luke's character.

(Image from IMDb)

Seemingly, Luke was out of character.  After all, he almost tried to kill his former student Kylo, and his verbal diatribe against the Jedi was surprising to say the least.  On closer look, however, I don't think he was out of character at all.  First off, Luke didn't try to murder Kylo.  Technically, he though about it and almost tried to, because he was so shocked when he looked into Kylo's corrupted soul.  But ultimately, Luke decided against murder, even if it didn't look that way to Kylo.

Second, Luke was right about the Jedi.  They were overly rigid and emotionally repressive, which played a role in Anakin Skywalker's meltdown into Darth Vader.  Moreover, the Jedi understanding of the Force was narrow-minded at best.  Consider Luke's ongoing dialogue with Rey: first, where Rey gets the Force wrong; and then when she gets it right.

(Image from IMDb)

Luke: What do you know about the Force?
Rey: It's a power that Jedi have that lets them control people ... and make things float.
Luke: Impressive.  Every word in that sentence was wrong.

Luke: What do you see.
Rey: The island.  Life and decay, that feeds new life.  Warmth.  Cold.  Peace.  Violence.
Luke: And between it all?
Rey: Balance and energy.  A force.
Luke: And inside you?
Rey: Inside me, that same force.

Bingo!  The Force doesn't belong to an aristocracy like the Jedi or the First Order.  That's why Rey wasn't a child of royalty or Skywalker lineage.  It's why she didn't truly have any special connection with Kylothat connection was just concocted by Snoke.  And it's why Snoke was no one special eitherjust some jackass in space who got what he deserved in the end.  Who does the Force belong to?  Nobody.  Which really means everybody.  Thus, the movie concludes with a young Force-sensitive slave.  You can't get more democratic than that!

But even if you don't agree with The Last Jedi's democratic spirit, can we at least agree that Porgs are adorable?

Dopamine-Driven Feedback Loops: Unintended Consequences of Social Media

I may be too optimistic right now, but 2017 may mark the year when people awoke to the unintended consequences of social media.

We saw the US government grill representatives from Facebook, Twitter, and Google about the propagation of fake news over the web.

Now we've seen former executives from Facebook come out to discuss the damage that their platforms have done to public discourse.

I wanted to highlight two interviews that caught my attention.  They show how new media have ecological consequences: when we add new technologies to the environment, they change the entire environment, often with unintended consequences (see my prior posts on media ecology).

Sean Parker, one of the founders of Facebook (played by Justin Timberlake in the movie The Social Network), has pointed out the fact that Facebook is designed like an addictive drug.  Every time you see more likes, comments, or shares online, you get a blast of dopamine (a chemical that signals immediate reward to your brain), which gets you coming back for more likes, comments, shares, etc.

The result is what Parkers called a “social-validation feedback loop” that exploits “a vulnerability in human psychology."

The thought process that went into building these applications, Facebook being the first of them ... was all about: 'How do we consume as much of your time and conscious attention as possible?’

And that means that we need to sort of give you a little dopamine hit every once in a while, because someone liked or commented on a photo or a post or whatever. And that's going to get you to contribute more content, and that's going to get you ... more likes and comments.
It's a social-validation feedback loop ... exactly the kind of thing that a hacker like myself would come up with, because you're exploiting a vulnerability in human psychology.

Parker isn't alone in his assessment.  Chamath Palihapitiya, a former Facebook executive, has come out with a similar concern.  He goes so far as to express “tremendous guilt” about how “we have created tools that are ripping apart the social fabric of how society works."

The short-term, dopamine-driven feedback loops that we have created are destroying how society works: no civil discourse, no cooperation, misinformation, mistruth.

Okay, let me admit that I’m a still user of Facebook, although lately I’ve considered deleting my account.  Here’s the question I have to ask myself: What value is this media truly bringing to my life?  When I reflect on this question, here's the honest answer: not much.

Facebook does help me keep in touch with friends and organize groups and events with them (mainly, I use Facebook to organize get-togethers).  However, I’m not afraid to admit that I find most communication on social media to be superficial and phatic.

At this point, I agree with both Parker and Palihapitiya’s temporary solution (which you can hear in their full interviews): only use Facebook minimally.  Very minimally.  Make sure the majority of social interaction in in the real world, not the virtual one.

Is Big Tech a Threat to Democracy?

This last month, we saw something unprecedented in the world of big tech.  Executives from Facebook, Twitter, and Google testified on Capitol Hill to address how the Kremlin used their platforms to spread propaganda and fake news over the Internet.

A lot of problems were discussed about disinformation over the web, and yet these problems all seems to be part of a larger problem: the formation of digital tribes.  People are already prone to what psychologists call the confirmation bias (a tendency to seek out information that confirms what we already want to believe), and social media makes this tendency so much easier.  As The Economist recently wrote,

The algorithms that Facebook, YouTube and others use to maximize “engagement” ensure users are more likely to see information that they are liable to interact with.  This tends to lead them into clusters of like-minded people sharing like-minded things, and can turn moderate views into more extreme ones.

Since I’m quoting it, I’d encourage everyone to check out this recent issue of The Economist—it should be required reading for students.

(Image from The Economist)

I remember back in some of my grad school seminars (my M.S. is in Scientific & Technical Communication with a minor in cognitive science), when professors and students were arguing how social media would revolutionize democracy.  More people, they claimed, would be able to participate in civic dialogue using social media, which would help participatory democracy flourish.

Well, social media didn’t revolutionize democracy.  Instead, social media seem to be replacing democracy with echo chambers of ideological prattle susceptible to fake news.  This can be entertaining and amusing but not necessarily democratic or informative.  As Neil Postman, the founder of media ecology, warned in his famous book (pictured below), we're in danger of amusing ourselves to death.

(Image from Amazon)

But let’s be practical: big tech isn’t going anywhere, and social media are great for some things, such as organizing events and sharing entertainmentpoints Clay Shirky makes in his books.  When it comes to civics, however, the big tech companies are not enhancing democracy or dialogue.  Going forward, they may need to prepare themselves for regulation and oversight to mitigate the unintended consequences of social media.

For example, just as we regulate large banks as trustees of our money so that they don't endanger our economic institutions, we may want to regulate big tech companies as trustees of our data so that they don't endanger our democratic institutions.

Consuming a Balanced Media Diet: digital tribes, information bubbles, and the matrix

I've said it before, I'll say it again: digital technology has played a major role in the rise of "digital tribalism"which means groups and people use digital technologies to construct information bubbles.  The paradox of the Digital Age is that we're more interconnected than ever, and yet we use search engines, social media, and recommendation systems to insulate ourselves from ideas outside our information bubbles.

Don't like the facts?  Google your own 'facts' instead.

The best thing about the Internet is that you can find out anything about anything.  That's also the worst thing about the Internet.

For example, if you're curious about climate, genetics, or vaccines, you can easily find educational resources such as Scientific American.  But if you don't want to believe in climate science, evolution, or vaccinations, it's also easy to find sites that assure you that global warming is a conspiracy, evolution is a hoax, and vaccines are dangerous.  Anyone can Google whatever they want to believe nowadays, and somewhere in the digital universe, there will be a website propagating blatantly false information that misrepresents basic scientific, historical, and medical facts.

Don't like other viewpoints?  'Unfriend' them.

If you don't like what someone says on Facebook or Twitter, you can 'unfriend' or 'unfollow' that person.  More and more people did that to others during the last election, and, unfortunately, it's just reinforcing digital tribes of liberals and conservatives.  I say unfortunately because, in the end, people only see what they are ideologically predisposed to like in their feed, and few are challenged by different viewpoints.  As a result, fewer people can have conversations, constructively disagree, or defend their own points of view, because they don't want to be questioned.

Only want to see what you'd like to see?  Let online recommendations make your decisions.

It's not just search engines and social media that are isolating us into digital tribes.  Online shopping is doing that too.  Take the recommendation system on Amazon as an example.  The Economist ran an analysis that looked at how online recommendations from Amazon influence customers who buy political books.  The result was summed up in the following graphic, which shows how left-leaning shoppers tend to buy only left-leaning books, just as right-leaning shoppers tend to buy only right-leaning books.

Source: the Economist, September 30th, 2017

As you can see, very few readers end up even looking at other political viewpoints.  The online recommendations are not only making decisions for customers.  Customers are also letting online recommendations determine what they end up knowing.  As the Economist concludes,
Jeff Bezos, Amazon's founder, has bought the Washington Post, and urged upon it the motto: "Democracy Dies in Darkness".  But Amazon conquered the book market in part on the strength of its "recommendation engine".  That now contributes to the dark spots in Americans' knowledge of their political opposites.  Whether Amazon willor even cando anything to change that is yet to be seen.
Trapped in the matrix ... of information bubbles and digital tribes

As we can see, search engines, social media, and online recommendations don't necessarily expose us to diverse ideas.  On the contrary, they may trap us inside our own information bubbles.  If you were wondering what The Matrix was an allegory for, now you know.

Or, to go from science fiction to science fact, here's why Google, Facebook, and Amazon don't necessarily open up our minds: digital technologies makes us prone to what psychologists call the confirmation bias (finding info that conforms to our beliefs).  No wonder they make us more tribal.

What to do now?  Try a balanced media diet.

So how do we overcome digital tribalism?  It's a question I ponder often these days, so please let me know if you have any suggestions.  One I have is what I like to call a balanced media diet.  The important thing to remember is that different types of media can affect our lives and minds differently (studying these differences is called media ecology), so moderation (as opposed to overdosing) is key.

Just as it's physically unhealthy to eat only one type of mineral, it's mentally unhealthy to consume only one type of media.  For instance, calcium is essential for a healthy body, but if all I consume is calcium, my body will be in serious trouble.  The same goes for media.  If all or most of my information and interaction comes from social media, my mind will lose its ability to focus and reflect, and my social skills will wane.  So maybe try this: for every minute you spend in front of a screen, spend the same amount of time reading a book and/or conversing with friends, family, or colleagues.  If you're lucky, they'll introduce you to new ideas, question your previously unchallenged beliefs, and pop your information bubble.
