Do you know 3.5% rule?

The “3.5% rule” comes from Erica Chenoweth, a political scientist at Harvard, who found it was a useful predictor of a protest’s success — The Economist.

Erica’s TED talk is accessible from here.

Researchers used to say that no government could survive if just 5% of its population rose up against it.

No single campaign failed after they achieved the active and sustained participation of the 3.5% of the population.

Every single campaign that surpassed the 3.5% was non-violent one.
