How many zombies do you know? Good question! Andrew Gelman, zombie researcher and statistician, explains while possibly saying something about social network analysis. (H/T to Marginal Revolution, who totally missed the point)
See also Lakeland’s analysis of the effect of education on mortality rates to zombie invasion. Basically, it doesn’t help. And really, that should have been predicted, because the last thing you need in a zombie attack is MORE BRAINS! No, the math plainly shows that we can be saved only by scantily-clad teenage zombie killers. You can’t argue with math, people. For Christ’s sake, there are graphs! GRAPHS!
Edit: Speaking of zombies, check out this abomination against nature. The dead walk again!
