Word-of-Mouth & Virality Framework
A framework for engineering word-of-mouth and making products, ideas, and content contagious, based on Jonah Berger's research into why things catch on. Use it to design shareability into products, campaigns, and content instead of hoping for luck.
Core Principle
Virality is not born — it is engineered. Products spread because they were designed — consciously or not — to be shared. Only 7% of word-of-mouth happens online; the other 93% happens in offline conversations, so virality is about the psychology of sharing, not social media mechanics. Those psychological patterns are predictable and can be engineered into anything using the STEPPS framework.
Scoring
Goal: 10/10. Rate any product, campaign, content, or feature 0-10 on how many STEPPS drivers it activates and how well. Report the current score and the specific improvements needed to reach 10/10.
STEPPS Overview
Not a checklist — a multiplier. Each principle independently increases sharing; the most contagious ideas activate several at once, but even one or two done well dramatically increase word-of-mouth.

The STEPPS Framework
1. Social Currency
Core concept: People share things that make them look good — smart, cool, in-the-know. Make people feel like insiders and they'll spread it to boost their own image.
Why it works: Brands and information are social signals; people don't just share what they think — they share what makes them look good for thinking it.
Key insights:
- Remarkability — surprising, novel, or extreme things make the sharer seem interesting; "Did you know...?" is a powerful sharing trigger
- Game mechanics — leaderboards, badges, and status tiers create visible accomplishments people want to display
- Exclusivity and scarcity — secret menus and invite-only access give peopl
