Via Naked Capitalism, researcher Erica Chenoweth attempted to qualify which style of insurgency is more effective — she claims nonviolent action has a better yield:
Occupy’s public discussions on “diversity of tactics” have often lacked historical perspective; discussions, at least online, have tended to degenerate to “Ghandi!” “No, ANC!” Now, however, Erica Chenoweth has developed a dataset and analyzed the historical record. Below are the results of her study of 323 non-violent and violent campaigns from 1900‐2006. I’m sure, readers, that like any study, Chenoweth’s work is open to challenge on any number of grounds. That said, surely looking to the historical record to see what’s worked isn’t such a bad thing?
