摘要
Models of how things spread often assume that 傳播 mechanisms are fixed over time. However, 社會 contagions-the spread of ideas, beliefs, innovations-can lose or gain in momentum as they spread: ideas can get reinforced, beliefs strengthened, products refined. We study the impacts of such self-reinforcement mechanisms in cascade dynamics. We use different 數學 modeling techniques to capture the recursive, yet changing nature of the process. We find a critical regime with a range of powerlaw cascade size distributions with nonuniversal 縮放律 exponents. This regime clashes with classic models, where 臨界性 requires fine-tuning at a precise critical point. Self-reinforced cascades produce critical-like behavior over a wide range of parameters, which may help explain the ubiquity of power-law distributio
