This paper provided experimental evidence that social conventions can shift suddenly when committed minorities reach a critical threshold (~25% of population). The finding validates threshold models of collective behavior and provides concrete guidance for change initiatives.
The research demonstrates that quorum-like dynamics operate in human social systems, with specific thresholds triggering rapid collective transitions.
Key Findings from Centola et al. (2018)
- Committed minorities of ~25% can trigger population-wide convention change
- Transition from old to new convention is rapid once threshold crossed
- Below threshold, committed minority has little effect
- Tipping point dynamics are experimentally validated in social conventions
