Body
The empirical finding (Chenoweth & Stephan, Why Civil Resistance Works) that no movement failing to mobilise at least ~3.5% of a population has succeeded in the 20th/21st-century campaigns studied.
Erica Chenoweth’s research — now embodied in the NAVCO Data Project — found that across the dataset of maximalist nonviolent campaigns, every successful campaign mobilised at least ~3.5% of the population in active participation (not just sympathy) [source: navco]. The Women in Resistance (WiRe) Data Project extends the analysis with gender-disaggregated findings on what helps campaigns cross the threshold: leadership diversity, tactical innovation, and explicit inclusion of women as participants and decision-makers [source: wire-data]. The rule is best read as a threshold of viability, not a sufficient condition: success also requires strategic discipline, pillars-of-support analysis, and tactical escalation. The wrong takeaway is “wait until 3.5% before doing anything” — the threshold describes the level at which success becomes possible, not the level at which action becomes useful.

Setting realistic participation targets; arguing against premature victory claims when a campaign has <1% active participation; framing a long-term organising horizon.
