Why Things Catch On
by Jonah Berger
Who This Book Is For
The ideal reader is a builder responsible for growth without a giant ad budget: a PM, marketer, founder, creator, or nonprofit advocate. They own or influence the product and comms levers, are hypothesis-driven, ethically grounded, and impatient for results. They struggle with “people like it but don’t talk,” spikes without sustained adoption, and messaging that pleases execs but dies in the wild. They value practical playbooks, simple metrics, and ideas they can test this week. Comfortable with scrappy experiments, they respect users’ time and dignity, and prefer making the message inherently shareable over chasing “influencers.” They think in behaviors, not vanity views; in cues, not campaigns. After reading, they’ll map daily triggers, craft a brag line, add visible residue, package one screenshot-able utility, and wrap it all in a story that can’t be retold without the product. Curious, humble, and action-biased, they’ll iterate until spread aligns with impact.
