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, according to research by Harvard political scientist Erica Chenoweth.
Chenoweth's analysis of hundreds of campaigns over the last century found that nonviolent campaigns are twice as likely to achieve their goals as violent ones. Moreover, when at least 3.5% of the population actively participates in protests, serious political change is almost guaranteed.
Examples include the 1986 People Power movement in the Philippines, the 2003 Rose Revolution in Georgia, and the 2019 protests in Sudan and Algeria, all of which led to regime change through peaceful civil resistance.
Chenoweth initially doubted the effectiveness of nonviolent resistance, but after reviewing 323 violent and nonviolent campaigns from 1900 to 2006, she and co-researcher Maria Stephan found that nonviolent strategies consistently outperform violent ones.
Her findings have inspired modern movements such as Extinction Rebellion, whose founders cite the '3.5% rule' as a key motivation.
