Threshold Models of Collective Behavior
“Groups with the same average can diverge because their thresholds are distributed differently.”
01 / SUMMARY
In short
Threshold models represent participation as depending on how many others already participate. The distribution of thresholds can start a cascade or stop it early.
03 / SCENE
In the wild
One person joins a strike after ten participants; another needs one hundred, and each entry changes the next person's setting.
04 / LIMIT
The limit
A threshold is a modeling device, not a fixed hidden number that can be read from each person.
FINAL NOTE
What remains
Study the distribution and activation order, not only the group's average willingness.
