How to Play to Win

Malcolm Gladwell has written yet another delightful article. This one is in the New Yorker and deals with strategy and tactics when you are an underdog. As usual, Gladwell builds his argument from little nuggets, stories, that relentlessly make his point:
Ranadivé was puzzled by the way Americans played basketball. He is from Mumbai. He grew up with cricket and soccer. He would never forget the first time he saw a basketball game. He thought it was mindless. Team A would score and then immediately retreat to its own end of the court. Team B would inbound the ball and dribble it into Team A’s end, where Team A was patiently waiting. Then the process would reverse itself. A basketball court was ninety-four feet long. But most of the time a team defended only about twenty-four feet of that, conceding the other seventy feet. Occasionally, teams would play a full-court press—that is, they would contest their opponent’s attempt to advance the ball up the court. But they would do it for only a few minutes at a time. It was as if there were a kind of conspiracy in the basketball world about the way the game ought to be played, and Ranadivé thought that that conspiracy had the effect of widening the gap between good teams and weak teams. Good teams, after all, had players who were tall and could dribble and shoot well; they could crisply execute their carefully prepared plays in their opponent’s end. Why, then, did weak teams play in a way that made it easy for good teams to do the very things that made them so good?

...

David’s victory over Goliath, in the Biblical account, is held to be an anomaly. It was not. Davids win all the time. The political scientist Ivan Arreguín-Toft recently looked at every war fought in the past two hundred years between strong and weak combatants. The Goliaths, he found, won in 71.5 per cent of the cases. That is a remarkable fact. Arreguín-Toft was analyzing conflicts in which one side was at least ten times as powerful—in terms of armed might and population—as its opponent, and even in those lopsided contests the underdog won almost a third of the time.

...

Arreguín-Toft found the same puzzling pattern. When an underdog fought like David, he usually won. But most of the time underdogs didn’t fight like David. Of the two hundred and two lopsided conflicts in Arreguín-Toft’s database, the underdog chose to go toe to toe with Goliath the conventional way a hundred and fifty-two times—and lost a hundred and nineteen times. ... George Washington did the same in the American Revolution, abandoning the guerrilla tactics that had served the colonists so well in the conflict’s early stages. “As quickly as he could,” William Polk writes in “Violent Politics,” a history of unconventional warfare, Washington “devoted his energies to creating a British-type army, the Continental Line. As a result, he was defeated time after time and almost lost the war.”

It makes no sense, unless you think back to that Kentucky-L.S.U. game and to Lawrence’s long march across the desert to Aqaba. It is easier to dress soldiers in bright uniforms and have them march to the sound of a fife-and-drum corps than it is to have them ride six hundred miles through the desert on the back of a camel. It is easier to retreat and compose yourself after every score than swarm about, arms flailing. We tell ourselves that skill is the precious resource and effort is the commodity. It’s the other way around. Effort can trump ability—legs, in Saxe’s formulation, can overpower arms—because relentless effort is in fact something rarer than the ability to engage in some finely tuned act of motor coördination.

...

Insurgents work harder than Goliath. But their other advantage is that they will do what is “socially horrifying”—they will challenge the conventions about how battles are supposed to be fought. All the things that distinguish the ideal basketball player are acts of skill and coördination. When the game becomes about effort over ability, it becomes unrecognizable—a shocking mixture of broken plays and flailing limbs and usually competent players panicking and throwing the ball out of bounds. You have to be outside the establishment—a foreigner new to the game or a skinny kid from New York at the end of the bench—to have the audacity to play it that way. George Washington couldn’t do it. His dream, before the war, was to be a British Army officer, finely turned out in a red coat and brass buttons. He found the guerrillas who had served the American Revolution so well to be “an exceeding dirty and nasty people.” He couldn’t fight the establishment, because he was the establishment.
You really should read the whole article. It is delightful. It is typical Malcolm Gladwell.

However, for me the killer bit was this throwaway comment Gladwell made about central bank financial policy:
A few years ago, Ranadivé wrote a paper arguing that even the Federal Reserve ought to make its decisions in real time—not once every month or two. “Everything in the world is now real time,” he said. “So when a certain type of shoe isn’t selling at your corner shop, it’s not six months before the guy in China finds out. It’s almost instantaneous, thanks to my software. The world runs in real time, but government runs in batch. Every few months, it adjusts. Its mission is to keep the temperature comfortable in the economy, and, if you were to do things the government’s way in your house, then every few months you’d turn the heater either on or off, overheating or underheating your house.” Ranadivé argued that we ought to put the economic data that the Fed uses into a big stream, and write a computer program that sifts through those data, the moment they are collected, and make immediate, incremental adjustments to interest rates and the money supply. “It can all be automated,” he said. “Look, we’ve had only one soft landing since the Second World War. Basically, we’ve got it wrong every single time.”
In the context of the article this comment was simply pointing out another example where the insiders define the rules, and therefore they ignore other viewpoints and thus lose the chance to creatively deal with a situation. The good news is that Ranadivé software company is thriving. The bad news is that they guys who define the rules, the central bankers, don't see that the underlying game has changed and they need to change the rules to accommodate reality. We need a David to take on the Goliaths of central banking.
