Complex contagions (costly or controversial behaviors) need reinforcement from multiple contacts to spread, unlike simple contagions. Includes the 2010 Science online-network experiment.
The book’s stance. Bears on complexity-virality-inverse, complexity-ceiling-by-network-size, and Chapter 9’s sparse-bridges prescription. Supports the complexity/spread inverse; pressure-tests “bridges sparse enough” — complex ideas need wide, redundant bridges, not thin ones. Quote-backed supports/pressureTests edges pending extraction of the source PDF.
