The Big Idea
People share what makes them look good, feel something, and carry useful proof.
Contagious is a field guide for making ideas travel through people instead of through paid media. The book's core move is practical: do not ask, "How do we get attention?" Ask, "What gives someone a reason to pass this along?"
The six STEPPS are not a checklist for gimmicks. They are lenses for diagnosing why one restaurant, product, rumor, campaign, or public-health message becomes talkable while another disappears. Spread begins when the audience gets a reward for carrying the message.
STEPPS Framework
Six editorial hooks for word-of-mouth.
Each hook gives the sharer a job: signal taste, remember at the right moment, transmit feeling, make behavior visible, help a friend, or smuggle the idea inside a story.
T
STEPPS
Triggers
Attach the idea to cues that appear naturally in everyday life.
E
STEPPS
Emotion
High-arousal feelings move people from noticing to forwarding.
P
STEPPS
Public
Make the behavior observable so imitation has something to copy.

Practical Value
Package usefulness so people can help others with low effort.

Stories
Wrap the lesson in a narrative people can retell without losing the point.
Interactive Desk
Edit an idea until it wants to travel.
Pick an ordinary seed, then toggle the STEPPS you can honestly build into it. The front page rewrites itself as your word-of-mouth architecture improves.

Field Notes
Make the sharer the hero, not the campaign.
Package status
Give people a way to signal taste, expertise, generosity, or insider access when they talk about the idea.
Borrow daily cues
Tie the message to a frequent environment, phrase, habit, day, or object so memory gets prompted.
Design for retelling
Reduce the idea to a vivid scene, surprising fact, or useful script that survives being repeated.
Show the behavior
If adoption is invisible, build public artifacts, rituals, badges, or defaults that others can notice.

Core Insights
"People do not share randomly. They share because the act gives them social currency."
Practical Application
Engineer the pass-along moment.
Use these actions when an idea is good but too quiet, too private, too generic, or too hard to retell.
01
Name the sharer's reward
Before writing the message, define how repeating it makes someone look: generous, early, tasteful, funny, competent, or principled.
I'll do this
02
Attach the idea to a real-world cue
Pick one recurring trigger already in your audience's life, then rewrite so that cue reminds them to mention or use the idea.
I'll do this
03
Raise one high-arousal emotion
Replace flat benefits with awe, urgency, surprise, delight, or righteous frustration that gives people energy to pass it on.
I'll do this
04
Hide the lesson inside a story
Write the anecdote someone would tell at lunch — with the product or insight essential to the punchline.
I'll do this
05
Make adoption visible
Create a public artifact, ritual, badge, receipt, phrase, or behavior observers can notice without an explanation.
I'll do this
06
Package the useful bit
Turn practical value into a compact pass-along asset: checklist, rule of thumb, comparison, template, or timely tip.
I'll do this
07
Rewrite one line for social currency
Edit one message so sharing it makes the sharer look good for a reason you can name.
I'll do this
08
Add one practical pass-along asset
Turn today's insight into a checklist, template, or one-liner someone can forward.
I'll do this
