Mills: whether an idea, product, or behavior spreads depends as much on the structure of the social network as on the quality of the content. Well-connected individuals at network hubs can make mediocre ideas go viral, while brilliant ideas from poorly connected individuals die in obscurity.
Highlights
•
Emotional arousal drives sharing — high-arousal emotions (anger, awe) spread faster than low-arousal ones (sadness, contentment)
Mills: Jonah Berger's research shows that content evoking high-arousal emotions (anger, anxiety, awe, excitement) is shared significantly more than content evoking low-arousal emotions (sadness, relaxation, contentment). The arousal, not the valence, determines virality.Was this useful?
