After some prodding by Gauntlet
, I decided to take a read through The Black Swan
and, I must say, I’m glad I did. It’s simply one of the most thought provoking books I’ve
read in a long time.
So what is The Black Swan about? Well, statistics. And history. And economics. And philosophy. And pretty much everything else under the sun. Nassim
Nicholas Taleb doesn
’t really touch on politics except for a few veiled shots at the stupidity of thinking liberating Iraq would be a walk in the park, but the black swan principle certainly has some very useful applications to politics - I’ll get to that in a second.
First, the book. The Black Swan is about randomness. Not controlled randomness like casinos, but about things that we just don’t see coming that change the world. 9/11 would be a black swan. The dominance of the internet
and of Google
would be a black swan, because no one would have even conceived of it a decade before it happened. In politics, the 1993 election, featuring the rise of the BQ
and Reform Party, would be a major black swan since no one saw it coming. Kim Campbell certainly didn
’t think the party of John A would be down to a pair of seats and, at most, the Bloc was just a temporary ad hoc
rainbow coalition that no one believed would ever become her majesty’s loyal opposition.NNT
takes this somewhat basic concept of the black swan and explores it from several angles. He divides the world into mediocristan
. In mediocristan
, you don’t get big outliers or deviations. So body weight would be in mediocristan
because one person, no matter how many Tim Hortons
triple chocolate donuts he eats, will never deviate dramatically from the average body weight. Something like wealth would be in extremistan
since a guy like Bill Gates can really skew the average. Events in extremistan
are susceptible to black swans which is why war casualties, stock market crashes, and disease outbreaks can come out of nowhere to dramatically change the world.
The part of the book probably most relevant to politics is NNT
’s rant against “experts”. Most of his scorn is directed against economists whose speculation is hardly ever accurate, but it could just as easily be an attack on political pundits. “Expert” pundits are almost always wrong. Consider predictions for things like election timing, leadership races, or even politicians and elections (Prime Minister Bernard Lord anyone?). Rather than pick on the print media to illustrate this point, I’ll take a shot at myself (since I’m not paid to make predictions, I really don’t mind being wrong). In 2005, I got to musing
about the next Liberal leadership race and concluded that the four main contenders for the crown were John Manley, Frank McKenna
, Martin Cauchon
, and Scott Brison
. Three of those guys didn
’t run and the other probably wishes he hadn
’t. I mentioned the 1993 election before, but the rise of the ADQ
, or any of the three government changes Alberta has enjoyed in its history could all be considered political black swans. I think the moral is that politics is rooted in extremistan
and that making predictions, especially long term predictions, is an exercise in futility. It also means that things we could never even conceive of today are certainly possible. Maybe that’s why lifelong Dippers or Alberta Liberals stay around in politics.
Another beef of NNTs
that is especially applicable to politics is his complaint against historians. After taking an undergrad
degree in history, I have always felt there was a certain over eagerness to explain everything and make every historical event seem predictable. I think every person alive has had to do a “causes of World War 1” essay at some point in their lives. Maybe the rise of Hitler or the fall of communism were predictable, but when hardly anyone was predicting them you have to wonder if it wasn
’t just a fluke that historians are trying to find a logical reason for post hoc
. In politics, it seems that pundits (who were 100% wrong beforehand) will pontificate after the fact about how obvious event X should have been to everyone beforehand. Winners are deemed to be political geniuses who ran flawless campaigns and losers are deemed to be inept fools. I can guarantee you that had Martin fluked into a majority government in 2004, pundits would be praising the Mad as Hell tour as a stroke of genius. And by "pundits", I don’t mean just John Duffy.NNT
also talks about a lot of problems with statistics that I’m 100% in agreement with. I won’t get into a lengthy lecture on this since I doubt many of my regular readers are bell curve enthousiasts
, but the cavalier disregard for outliers and need to normalize distributions has always stood out to me as a problem in statistics. Not so much among people who know what they’re talking about but more so among amateurs. NNT's passionate
hate of the bell curve borders on the obsessive and that's probably a little unfair since it does serve it's purpose for normal data from mediocristan
- you only run into problems when people toss the underlying assumptions out the door and misuse it.
As for the book itself, it’s certainly not an academic text by any means which makes it a fun read. NNT
’s sarcasm and jokes (mostly about frenchmen)
are sprinkled throughout the book and he can be scathingly critical of those he dislikes. Good for him – it makes it a more enjoyable read. NNT
comes across like an arrogant know it all at times but his arguments are generally sound so it’s hard to get too worked up about it.
So if you’re looking for a book that will make you think a bit and explain society – something kind of like Tipping Point – I would certainly suggest you pick up a copy. If you’re using statistics for predicative purposes in a field other than statistics, I would insist
you pick up a copy.
