The ‘3.5% rule’: How a small minority can change the world

Harvard University political scientist Erica Chenoweth determined that civil disobedience is the most powerful and successful way to achieve political change.  Per journalist David Robson, "Nonviolent protests are twice as likely to succeed as armed conflicts – and those engaging a threshold of 3.5% of the population have never failed to bring about change."  Chenoweth's research suggests that non-violent protests engaging about 11 million American citizens could realize significant political change.
