Don't blame the experts who didn't see the Arab Spring coming.
Blake Hounshell is right ("Dark Crystal," July/August 2011) that "experts," including myself, failed to predict the Arab revolutions. However, there are a few nuances that may make us appear less inept.
First, any revolution, as Charles Kurzman correctly notes, is a low-to-moderate probability event in any given year. We can do a very good job distinguishing more unstable states from very stable ones, but we can't always say which state or states will have a crisis next year. Similarly, a doctor may be able to say that patients who are overweight and have high blood pressure are at a much higher risk of having a heart attack, but can't know which patient is going to have a cardiac episode in the coming year.
More importantly, our forecasting models are capable of being adjusted in response to events. Once the Tunisian revolution occurred (unexpectedly!), we were able to look more closely at conditions in neighboring states and change our forecasts to anticipate a breakdown of order. We were much better able to anticipate the rebellion in Libya, and my May/June Foreign Affairs article, which was originally drafted and circulated at the beginning of March, correctly anticipated the Syrian uprising that began on March 15. It also correctly forecast that the monarchies in Morocco, Jordan, Oman, and Saudi Arabia would remain far more stable than the personalist dictatorships in Tunisia, Egypt, Libya, Yemen, and Syria. So while we may have missed the first onset of events, our analysis was still helpful in other respects.
It would be ideal if everything in the world of politics were nicely predictable. But we are still far from being able to say exactly when and where one will strike.

Blake Hounshell replies:
Let me first humbly submit that I didn't predict the Arab revolutions either; nor did a number of other quantitative models of instability, including some very expensive systems used by U.S. government agencies. The one prominent individual I've found who claimed to have called Egyptian President Hosni Mubarak's fall ahead of time was Bruce Bueno de Mesquita, a political scientist whose forecasting models are used by … U.S. government agencies. I did not mean to single out Goldstone or his work, for which I have the highest regard.
Indeed, I have no doubt that quantifying political upheaval is a difficult but worthy endeavor, and I wish Goldstone well as he refines his models. In the right hands, they clearly have much to tell us -- and perhaps we'll even be better prepared for the next round of falling dictators, like, say, Belarus's Aleksandr Lukashenko and North Korea's Kim Jong Il.
In the meantime, as Mark Abdollahian, whose Sentia Group does forecasting work for various government agencies, told Wired magazine in February: "Think of this like Las Vegas. In blackjack, if you can do 4 percent better than the average, you're making real money."
