Network Structure & Formation
Degree, clustering, bridges and formation logic predict what flows — and what breaks.

GAMES
Prisoner's Dilemma + Cooperation
Solo incentives wreck the group; seven routes — repeat, punish, signal, sort — rebuild it.
SHARED JOBS: REASON · DESIGN
DIFFUSIONBass Diffusion (S-Curve)
Innovators plus imitators make the S-curve. Spend early on seeds, later on social proof.
SHARED JOB: DESIGN
LINEARCategorical & Threshold Models
Buckets and cutoffs turn messy attributes into testable if-then rules.

Schelling Segregation
Mild individual preference for similar neighbors aggregates to stark city-wide segregation.
Granovetter Threshold
Each person has a riot threshold; cascades depend on the distribution, not the average.
Standing Ovation (Page–Miller)
Quality plus sightlines plus personal thresholds explain why crowds stand — or don't.
