The Mathematics of War, Revisited

A few months back I wrote a post discussing Sean Gourley’s TED talk on the Mathematics of War; specifically, noting that his finding (a power-law distribution of attack frequency and severity in Iraq) was—well—old news. This set off an excellent discussion on, Sean’s work, my comments, and more generally how the social and hard sciences can clash. More recently, Tom Ricks of The Best Defense blog revisited Sean’s talk with his own skepticism, which induced a response from Sean, and further skepticism by Ricks. In defense of his work, Sean responded to Tom’s post with the following:

With this new approach we can do several important things that were not possible before. We can understand the underlying structure of an insurgency i.e. how an insurgency ‘decides’ to distribute its forces (weapons, people, money etc). Further, we can explain why this kind of insurgent structure emerges in multiple different conflict zones around the world. We can estimate the number of autonomous insurgent groups operating within a theatre of war. We can monitor and track a conflict through time to see how either sides strategies are affecting the state of the war. Finally we can compare the mathematical patterns of current ongoing wars with past wars to estimate how close they are to ending.

I think Sean’s work in extremely important, as in many ways our research interests run parallel and this project has great potential. That said, his response leaves me with more questions than answers, therefore, with Sean’s response in hand I would like to revisit the mathematics of war.

Interstate Conflict and Genetic Similarity; Consequences for COIN

It is common to assume that the differences among people are what cause them to go to war. A new working paper from the National Bureau of Economic Research, however, has a different theory. In “War and Relatedness,” authors Enrico Spolaore and Romain Wacziarg hypothesize that genetic similarities contribute to a history of repeated [...]

Is Human Altruism Evolved or Rationalized from Conflict?

A new study by Samuel Bowels of the Sante Fe Institute in the current issue of Science is getting considerable media attention. Bowels asks, “If more cooperative groups were more likely to prevail in conflicts with other groups, was the level of intergroup violence sufficient to influence the evolution of human social behavior?” That [...]

The “Mathematics of War” and What’s Old is New Again (and Again)

I have no doubt that Sean Gourley is a brilliant physicist, in fact, after reading over his website I well convinced of this. This is partly why I am a bit disappointed in the findings he discusses in the above TED talk.

It is worth the seven or so minutes to watch the video, but the [...]
