Threshold Model of Collective Behavior
Collective action is shaped by the distribution of activation thresholds within a group. Enough low-threshold actors can start a cascade by giving progressively more hesitant people the visible participation they need to join.
A crowd may contain hundreds of people ready to follow and still do nothing. The decisive absence is not support but starters: without enough people willing to move before everyone else, collective action never begins.
E1The crowd is a sequence, not a switch
People require different amounts of visible participation before they act. Low-threshold members move with little social proof; their behavior supplies evidence and permission to those with slightly higher thresholds. Each new participant can then bring the next band within range, creating the staged spread described by Group Contagion. The outcome therefore depends less on the group’s average enthusiasm than on whether its thresholds form a bridge from the first movers to the reluctant majority.
E1Potential energy is not a cascade
Many people being close to action is insufficient if nobody crosses the first thresholds. The model explains how participation can propagate once it becomes visible; it does not imply that every sympathetic or agitated group will spontaneously mobilize.
E1Recruit the first visible layer
When organizing collective action, identify the people willing to act before broad participation feels safe. Secure a small, visible commitment from them first, then approach the next-most-ready group with evidence that participation has already begun.

There must be "enough low threshold people in the group"; otherwise "the thing is not going to get started at all."
