Agon

I'm a big fan of abstract strategy games, particularly those played on hexagonally-tiled boards (such as the ones you can purchase here). One of my favorites is Agon. It's a challenging but easy to learn game that's deserves a much bigger following. Here is the write-up I did of the rules a few years ago.

Agon may be the oldest abstract strategy game played on a 6 by 6 by 6 hexagonally tiled board, first appearing as early as the late Eighteenth Century in France. The game reached it greatest popularity a hundred years later when the Victorians embraced it for its combination of simple moves and complex strategy.

The Pieces: Each player has one queen and six pawns a.k.a. guards placed in the pattern indicated below
Agon Start

The Objective: To place your queen in the center hexagon and surround her with all six of her guards.(below)
win


concentric

Moves: Think of the Agon board as a series of concentric circles (see above). Pieces can move one space at a time either in the same ring or the ring closer to the center. In the figure on the left, a piece on a hexagon marked 4 could move to an adjacent hexagon marked either 4 or 3. Only the queen is allowed to move into the center hexagon. The figure below shows possible moves.

moves

Capturing: A piece is captured when there are two enemy pieces on either side of it. The player with the captured piece must use his or her next move to place the captured piece on the outside hexagon.
captures
If the captured piece is a guard, the player whose piece was captured can choose where on the outer hex to place the piece. If the piece is a queen, the player who made the capture decides where the queen should go.

If more than one piece is captured in one turn, the player whose pieces were captured must move them one turn at a time.

If a player surrounds the center hexagon with guards without getting the queen into position, that player forfeits the game.

Dilation and contraction.

Our standard narrative is deeply invested in the idea that progress is ever accelerating and that we are always on the cusp of an unimaginable leap forward. One of the favorite devices used to sustain this belief is dilation/contraction. The rate of technological change and its impact on society in the past is underestimated (particularly when describing the periods of the late 19th/early 20th centuries and the postwar era) while the current rate of change is overestimated, often wildly so when it comes to near-future predictions.

The following by Jim Hoagland is a good example.
Driverless cars and trucks rule the road, while robots “man” the factories. Super-smartphones hail Uber helicopters or even planes to fly their owners across mushrooming urban areas. Machines use algorithms to teach themselves cognitive tasks that once required human intelligence, wiping out millions of managerial, as well as industrial, jobs.

These are visions of a world remade — for the most part, in the next five to 10 years — by technological advances that form a fourth industrial revolution. You catch glimpses of the same visions today not only in Silicon Valley but also in Paris think tanks, Chinese electric-car factories or even here at the edge of the Sahara.

Technological disruption in the 21st century is different. Societies had years to adapt to change driven by the steam engine, electricity and the computer. Today, change is instant and ubiquitous. It arrives digitally across the globe all at once.

It is essential to note that, despite decades of serious and aggressive research and development, none of these technologies currently exist (at least not at the levels implied here) and, with the exception of autonomous vehicles, they probably won't exist a decade from now. Even with AVs, ruling the road will probably take decades unless we start heavily regulating non-autonomous cars.

(As we've pointed out before, there is an important distinction between driverless cars and driverless trucks. While both are coming, the current economic case for autonomous trucking makes far more sense and the technological challenge of driving a relatively small number of routes is considerably less. Long haul truck driving has the potential to go away quite suddenly.)

It's true that outside factors often slowed implementation in fields like electricity in the past. Factories had to be reconfigured. Power lines had to be laid. This meant that the adoption of certain technologies was delayed, particularly in certain localities, but even with this, the rate of technological change around the turn-of-the-century and, to a somewhat lesser extent, in the postwar era, was stunning.

More importantly in this case, (barring the special case where a new technology can be uploaded without any kind of change or upgrade of hardware) the same basic issues still apply. Even with AV's, there's still development time, infrastructure and adoption to consider.

The day is coming when you'll be able to say an address into your phone and have your car on its way without ever leaving the comfort of your couch. The prognosis for Hoagland's other just-around-the-corner innovations is considerably less promising. There are daunting problems involved with using AI to take over complex, badly understood tasks that largely lack reliable and agreed-upon metrics of success. While as for flying cars, the obstacles are huge and we have a history of failed promises going back literally a century. Just because some compulsive liar whose primary accomplishment has been getting gullible venture capitalists to write him ginormous checks makes this particular promise doesn't mean you should report it in the pages of the Washington Post as a done deal.

But even allowing for the vanishingly small chance that all of these things do come to pass roughly in the time frame given, we would still be nowhere near the level of technological change that people in the late 19th and early 20th centuries had to adapt to in virtually every aspect of their world, from day-to-day living to industry to transportation to mass media to telecommunications to medicine to agriculture and to all the others that I have invariably left off the list.

Insert obligatory what's-a-newspaper? joke here

Another small piece (or, more accurately, medium-size piece of a big piece) of the late 19th/early 20th century technology spike.

Media innovation was a big part of this story, not in the same league as internal combustion and electricity, but still a big player marked with a number of stunning advances.Most of the attention here tends to go to the then completely new developments such as recorded sound and moving pictures, but in terms of impact, advances in printing may have had more of an effect on the period.

I have been going through some old Scientific Americans for material and came across this excellent example from 1896. In the middle of the century, putting out a major metropolitan daily required the equivalent of a medium-size, well staffed factory.




By the last decade of the century, the presses were five times as fast, a fraction of the size, and largely automated.





This and other technological innovations (such as color printing) made publications like the Strand magazine and journalistic events like the Hearst/Pulitzer circulation wars and the rise of the comic strips possible. All of this had an enormous impact on American culture and politics.

The Republicans' 3 x 3 existential threat

I've argued previously that Donald Trump presents an existential threat to the Republican Party. I know this can sound overheated and perhaps even a bit crazy. There are few American institutions as long-standing and deeply entrenched as are the Democratic and Republican parties. Proposing that one of them might not be around 10 years from now beggars the imagination and if this story started and stopped with Donald Trump, it would be silly to suggest we were on the verge of  a political cataclysm.

But, just as Trump's rise did not occur in a vacuum, neither will his fall. We discussed earlier how Donald Trump has the power to drive a wedge between the Republican Party and a significant segment of its base [I wrote this before the departure of Steve Bannon. That may diminish Trump's ability to create this rift but I don't think it reduces the chances of the rift happening. – – M.P.]. This is the sort of thing that can profoundly damage a political party, possibly locking it into a minority status for a long time, but normally the wound would not be fatal. These, however, are not normal times.

The Republican Party of 2017 faces a unique combination of interrelated challenges, each of which is at a historic level and the combination of which would present an unprecedented threat to this or any US political party. The following list is not intended to be exhaustive, but it hits the main points.

The GOP currently has to deal with extraordinary political scandals, a stunningly unpopular agenda and daunting demographic trends. To keep things symmetric and easy to remember, let's break each one of these down to three components (keeping in mind that the list may change).


With the scandals:

1. Money – – Even with the most generous reading imaginable, there is no question that Trump has a decades long record of screwing people over, skirting the law, and dealing with disreputable and sometimes criminal elements. At least some of these dealings have been with the Russian mafia, oligarchs, and figures tied in with the Kremlin which leads us to…

2. The hacking of the election – – This one is also beyond dispute. It happened and it may have put Donald Trump into the White House. At this point, we have plenty of quid and plenty of quo; if Mueller can nail down pro, we will have a complete set.

3. And the cover-up – – As Josh Marshall and many others have pointed out, the phrase "it's not the crime; it's the cover-up" is almost never true. That said, coverups can provide tipping points and handholds for investigators, not to mention expanding the list of culprits.


With the agenda:

1. Health care – – By some standards the most unpopular major policy proposal in living memory that a party in power has invested so deeply in. Furthermore, the pushback against the initiative has essentially driven congressional Republicans into hiding from their own constituents for the past half year. As mentioned before, this has the potential to greatly undermine the relationship between GOP senators and representatives and the voters.

2. Tax cuts for the wealthy – – As said many times, Donald Trump has a gift for making the subtle plain, the plain obvious, and the obvious undeniable. In the past, Republicans were able to get a great deal of upward redistribution of the wealth past the voters through obfuscation and clever branding, but we have reached the point where simply calling something "tax reform" is no longer enough to sell tax proposals so regressive that even the majority of Republicans oppose them.

3. Immigration (subject to change) – – the race for third place in this list is fairly competitive (education seems to be coming up on the outside), but the administration's immigration policies (which are the direct result of decades of xenophobic propaganda from conservative media) have already done tremendous damage, caused great backlash, and are whitening the gap between the GOP and the Hispanic community, which leads us to…



Demographics:

As Lindsey Graham has observed, they simply are not making enough new old white men to keep the GOP's strategy going much longer, but the Trump era rebranding of the Republican Party only exacerbates the problems with women, young people, and pretty much anyone who isn't white.

Maybe I am missing a historical precedent here, but I can't think of another time that either the Democrats or the Republicans were this vulnerable on all three of these fronts. This does not mean that the party is doomed or even that, with the right breaks, it can't maintain a hold on some part of the government. What it does mean is that the institution is especially fragile at the moment. A mortal blow may not come, but we can no longer call it unthinkable.

Lots of threads converging on this one

And all of them tremendously important. Corruption and regulatory capture. An almost mystical faith in the magic of markets and private-enterprise approaches (even if they end up being all but completely government-subsidized). An inexhaustible tolerance for concentration of wealth and power. Internalized Randianism complete with the belief that the rest of us owe a debt to the rich and powerful that we can never fully repay. Regulatory capture and occasionally good old-fashioned corruption.

Thank God for John Oliver.

Kruzno

A few years ago, when I was teaching high school, I designed some games to illustrate mathematical concepts and develop strategic thinking and problem-solving skills. The clear winner in terms of player response was a game called Kruzno.



Despite the pieces (I decided to go with something off the shelf for the prototype), it's not a chess variant. Instead, it's a capture-and-evade abstract strategy game where the rank of the pieces is non-transitive. The rules are simple enough for a small child to play but challenging enough to keep reasonably competent chess players on their toes. It is also the official game of a small village in Slovakia, but that's a story for another time.


Between now and Christmas, I'll be writing some posts on game design and possibly sharing some thoughts and cautionary tales about jumping into a small business with no relevant experience. In the meantime, I still have some of that first run up for sale on Amazon. Go by and check it out.

Another Tesla article from the Scientific American archives (along with some very cool train pictures).

19th Century drawing of a Geissler tubes.






This story mainly stands on its own but there are a couple points I want to emphasize. First, it's a nice example of that distinctive Tesla combination: important innovator; savvy showmen; extravagantly over-promising flake. That's not just something that shows in retrospect; you can see it coming through contemporary accounts. Sober observers were well aware of all of these facets. The man was capable of amazing advances; he also reported getting messages from Mars.

I also like the way the story knocks down a false but persistent trope. There's a tendency to treat earlier generations as innocent and unimaginative, often oblivious to the extraordinary events that were starting to unfold. Call it the "little did they imagine" genre. The trouble is it's almost entirely wrong. Particularly in America, people in the late 19th and early 20th centuries saw themselves as living in a wondrous time and they tended to greet new developments with great excitement, if anything, often overestimating the degree to which their world was about to change.

Reading through these old articles, one thing that strikes me is that wildly ambitious ideas were not accepted unskeptically, but they weren't treated dismissively either. People seemed to get that an idea could fail miserably and still be of great value.

This is what a good job market looks like.

In the postwar era, employers (particularly what we would now call the stem fields) were genuinely hungry. They were willing to be flexible about qualifications and creative about recruiting.

"As God as my witness..." is my second favorite Thanksgiving episode line [Repost]



If you watch this and you could swear you remember Johnny and Mr. Carlson discussing Pink Floyd, you're not imagining things. Hulu uses the DVD edit which cuts out almost all of the copyrighted music. .

As for my favorite line, it comes from the Buffy episode "Pangs" and it requires a bit of a set up (which is a pain because it makes it next to impossible to work into a conversation).

Buffy's luckless friend Xander had accidentally violated a native American grave yard and, in addition to freeing a vengeful spirit, was been cursed with all of the diseases Europeans brought to the Americas.

Spike: I just can't take all this mamby-pamby boo-hooing about the bloody Indians.
Willow: Uh, the preferred term is...
Spike: You won. All right? You came in and you killed them and you took their land. That's what conquering nations do. It's what Caesar did, and he's not goin' around saying, "I came, I conquered, I felt really bad about it." The history of the world is not people making friends. You had better weapons, and you massacred them. End of story.
Buffy: Well, I think the Spaniards actually did a lot of - Not that I don't like Spaniards.
Spike: Listen to you. How you gonna fight anyone with that attitude?
Willow: We don't wanna fight anyone.
Buffy: I just wanna have Thanksgiving.
Spike: Heh heh. Yeah... Good luck.
Willow: Well, if we could talk to him...
Spike: You exterminated his race. What could you possibly say that would make him feel better? It's kill or be killed here. Take your bloody pick.
Xander: Maybe it's the syphilis talking, but, some of that made sense.

Igon values, superstar coin flippers, and the Gladwell problem

Malcolm Gladwell has started coming up in quite a few major threads and larger pieces, so I decided I needed to get up to speed on some of the controversies involving the author. Some of the more substantial have centered around what Steven Pinker has called the Igon value problem

From Pinker's review of "What the Dog Saw"
An eclectic essayist is necessarily a dilettante, which is not in itself a bad thing. But Gladwell frequently holds forth about statistics and psychology, and his lack of technical grounding in these subjects can be jarring. He provides misleading definitions of “homology,” “sagittal plane” and “power law” and quotes an expert speaking about an “igon value” (that’s eigenvalue, a basic concept in linear algebra). In the spirit of Gladwell, who likes to give portentous names to his aperçus, I will call this the Igon Value Problem: when a writer’s education on a topic consists in interviewing an expert, he is apt to offer generalizations that are banal, obtuse or flat wrong.


Gladwell got the best of the follow up exchange, dismissing “igon value” as a spelling error while getting Pinker sucked into a bunch of secondary or even tertiary arguments. (One of the best indicators of intelligence is the ability to avoid discussions about the heritability of intelligence.)

The spelling error defense is technically correct but it misrepresents the main point of the criticism. First off, on a really basic level, this indicates poor fact checking on the part of Mr. Gladwell and the New Yorker. Even working under the relatively low standards of the blogosphere, I always try to Google unfamiliar phrases before quoting them. You'd think that the editors of America's most distinguished magazine would do at least that much.

More importantly, spelling errors fall in two basic categories. The first does not tell us anything substanitive about the writer. Given the ghoti insanity of the English language, being a bad speller does not necessarily imply a weak vocabulary or poor mastery of the language (put another way, not knowing whether it's double C or double S in "necessarily"does not necessarily suggest that you don't know what "necessarily" means). There are, however, cases (particularly involving transcription) where spelling errors can indicate that the writer is unfamiliar with the words in question. That appears to be the case here.

Pinker's central criticism largely boils down to phonetic reporting. Gladwell often goes into stories with a weak grasp of the field in question, as a result he frequently makes serious mistakes, constantly misses important subtleties, and is almost completely dependent on his subjects for understanding and context. Add to this poor fact checking and a disturbing nonchalance about getting the story right, and things can get ugly quickly.

Somewhat ironically, Gladwell hit back at Pinker for employing one of the same techniques which Gladwell is so proud of, picking a detail that told a good story and memorably illustrated a larger idea. The Igon Value Problem worked beautifully on those terms but it was far from the most serious or conclusive example available, even if we limit ourselves to the single article in question, "Blowing Up."

For example, the piece is very much invested in the idea of Taleb as Wall Street revolutionary. We could quibble about just how radical the Black Swan ideas and strategies are, but it is an entirely defensible interpretation. Unfortunately, Gladwell doesn't really understand which ideas are debatably new and which are familiar to anyone in finance. Here's an excerpt (starting and ending mid-paragraph):

There was just one problem, however, and it is the key to understanding the strange path that Nassim Taleb has chosen, and the position he now holds as Wall Street's principal dissident. Despite his envy and admiration, he did not want to be Victor Niederhoffer -- not then, not now, and not even for a moment in between. For when he looked around him, at the books and the tennis court and the folk art on the walls -- when he contemplated the countless millions that Niederhoffer had made over the years -- he could not escape the thought that it might all have been the result of sheer, dumb luck.

Taleb knew how heretical that thought was. Wall Street was dedicated to the principle that when it came to playing the markets there was such a thing as expertise, that skill and insight mattered in investing just as skill and insight mattered in surgery and golf and flying fighter jets.

...

For Taleb, then, the question why someone was a success in the financial marketplace was vexing. Taleb could do the arithmetic in his head. Suppose that there were ten thousand investment managers out there, which is not an outlandish number, and that every year half of them, entirely by chance, made money and half of them, entirely by chance, lost money. And suppose that every year the losers were tossed out, and the game replayed with those who remained. At the end of five years, there would be three hundred and thirteen people who had made money in every one of those years, and after ten years there would be nine people who had made money every single year in a row, all out of pure luck.

But of course, Taleb didn't have to "do the arithmetic in his head" because, like virtually everyone else on Wall Street, he had probably read almost the same analogy in a famous passage from A Random Walk Down Wall Street by Burton Malkiel [transcribed via Dragon so beware of homonyms]:

Perhaps the laws of chance should be illustrated. Let's engage in a coin flipping contest. Those who can consistently flip heads will be declared winners. The contest begins and 1,000 contestants flip coins. Just as would be expected by chance, 500 of them flip heads and these winners are allowed to advance to the second stage of the contest and flip again. As might be expected, 250 flip heads. Operating under the laws of chance, there will be 125 winners in the third round, the three in the fourth, 31 in the fifth, 16 in the sixth, and 8 in the seventh.

By this time, crowds start to gather to witness the surprising ability of these expert coin-flippers. The winners are overwhelmed with adulation. They are celebrated as geniuses in the art of coin-flipping, their biographies are written, and people urgently seek their advice. After all, there were 1000 contestants and only eight could consistently flip heads. The game continues and some contestants eventually flip heads nine and ten times in a row. [* If we had let the losers continue to play (as mutual fund managers do, even after a bad year), we would have found several more contestants who flipped eight or nine ads out of 10 and were therefore regarded as expert coin-flippers.] The point of this analogy is not to indicate that investment-fund managers can or should make their decisions by flipping coins, but that the laws of chance do operate and that they can explain some amazing success stories.


(I love that second paragraph. Pretty much any time I flip past CNBC it comes flooding back to mind.)

Malkiel published this book in 1973 and though it more than ruffled a few feathers, it quickly became one of the seminal books on investing. Malcolm Gladwell's New Yorker piece came out 25 years later.

None of this is meant to imply any kind of deliberate plagiarism. Quite the opposite. I very much doubt that Gladwell realized he was paraphrasing a well-known passage. What I strongly suspect happened was that Taleb cited this in an interview as a standard example that everyone would be familiar with, sort of like describing a situation as a "frog in boiling water."

Gladwell's unacknowledged paraphrase is yet another indication that he didn't understand the strange role that economic theory and particularly market efficiency (in this case the semi-strong variety) plays on Wall Street, a role that was central to his narrative. This would be bad enough if he was just shooting for a straightforward profile, but Gladwell insists on playing the deep thinker, making pseudo-profound points, even closing with a grand sweeping moral about human nobility:

“That is the lesson of Taleb and Niederhoffer, and also the lesson of our volatile times. There is more courage and heroism in defying the human impulse, in taking the purposeful and painful steps to prepare for the unimaginable.”

Gladwell loves to tell what Christopher Chabris has termed "just-so stories," cute little fables counterintuitive and surprising enough to catch the eye but neat and simple enough to go down easy. Paradoxically, pulling off that sort of simplicity requires that the writer have a deep and subtle understanding of his or her subject. Simplifying a subject you don't understand never goes well.
