Social change is often abrupt & unpredictable — why? | Cass Sunstein (2019)

Cass Sunstein, Rob Wiblin

Cass Sunstein explains that social change often emerges suddenly through the interplay of preference falsification, diverse action thresholds, and group polarization, as illustrated by the rapid cascade of the #MeToo movement. The event outlines how individuals conceal true beliefs due to social pressure until visible support from early adopters lowers the threshold for others to act, transforming private consensus into public momentum. Sunstein further advises activists to target hidden majorities and facilitate "easy" behavioral shifts while warning that timing remains unpredictable due to the random nature of social interactions.
