In the past week, an awful lot of people have asked me how to gauge whether nonviolent popular movements are actually gaining traction. Generally speaking, a lot of folks have done work on this over the years (see these criteria drawn from Gene Sharp’s work, and Peter Ackerman and Hardy Merriman’s checklist approach). I have my own set of four criteria, which I’ve often cited when asked. It’s worth mentioning them again in one place.

Size and diversity of participation. The success of mass movements is largely driven by their size. Because of this, an increase in the number and diversity of participants may be an indicator of a movement’s latent potential to succeed. This is particularly true if people who are not ordinarily “activists” begin to participate and if various classes, ethnicities, ages, genders, geographies, and other social distinctions are represented.

Nonviolent discipline. Every movement that seriously challenges the status quo eventually experiences repression. How the movement responds to repression—whether it maintains its own discipline and order in spite of repression—is a key determinant of the movement’s staying power. Movements that respond to such repression with rioting or street-fighting tend to fizzle out. But movements that respond to such repression with unity, resolve, and discipline often succeed. Nonviolent discipline often requires advance coordination, training, preparation, and decentralization, which are desirable for lots of reasons regardless.

Flexible & innovative techniques. Kurt Schock’s work tells us that movements need to consistently shift their techniques—particularly switching between concentrated methods like demonstrations and dispersed methods like strikes and stay-aways—in order to succeed. Movements that over-rely on single methods—like protests or rallies—are less likely to win in the end. What I tend to look for, then, is whether a movement seems to be using a variety of nonviolent techniques. In particular, I look to a movement’s ability to shift to lower-risk tactics, like stay-aways, when repression becomes intense.

Loyalty shifts. If economic and business elites, civil servants, security forces, state media, and other elites continue to enthusiastically support the movement’s adversary, then the mass movement is not yet having profound and observable political effects. However, if erstwhile elite supporters begin to abandon the opponent, remain silent when they would typically defend him, refuse to follow orders to repress dissidents, or drag their feet in carrying out day-to-day orders, the incumbent is losing his grip. Although loyalty shifts from various sectors are important, defection, desertion, or noncooperation by security forces can be especially impactful.

Of course, these four trends are also instructive in terms of how movements prepare for and wage nonviolent struggle.

A few more fun facts from the historical record, drawn from recent work with Maria Stephan and Kurt Schock:

The average nonviolent campaign takes about three years to run its course (that’s more than three times shorter than the average violent campaign, by the way). So these things do not unfold overnight. The average nonviolent campaign is about eleven times larger as a proportion of the overall population as the average violent campaign. Nonviolent resistance campaigns are ten times more likely to usher in democratic institutions than violent ones. And from 1900-2006, only 50% of democratic countries facing armed campaigns remained democratic in the aftermath. 90% of democratic countries facing nonviolent resistance campaigns remained democratic after the campaign ended. Mixing in a little bit of violence by the protestors does not help nonviolent campaigns succeed. Those campaigns that succeed with violent flanks tend to do so in spite of the violence rather than because of it. Countries that experience nonviolent resistance campaigns are about 15% less likely to experience a civil war in the aftermath than countries that experience armed resistance campaigns.
