When Do Protests Actually Work? — with Erica Chenoweth

Erica Chenoweth, a political scientist at Harvard's Kennedy School, has spent her career studying what makes nonviolent movements succeed or fail. She didn't set out to study this. While finishing her PhD on terrorism and political violence, she attended a workshop on teaching nonviolent resistance mostly to pad her CV. But she noticed something: nobody had done a quantitative study of whether nonviolent resistance actually works as an alternative to violence. So she and a colleague, Maria Stephan, teamed up to do one. Their 2011 book Why Civil Resistance Works analyzed 323 mass movements between 1900 and 2006 and found that nonviolent campaigns succeeded at a much higher rate than violent ones.

Erica Chenoweth, political scientist and professor at Harvard’s Kennedy School, joins Scott Galloway to break down what actually makes protest movements succeed.

They discuss why most movements fail, the four factors that drive real change, and why mass mobilization alone isn’t enough. They also unpack the “3.5% rule,” the role of business and institutional power, and whether economic resistance can be more effective than taking to the streets.
