Book review: CONTAGIOUS: Why Things Catch On

Though replete with engaging case studies on marketing masters such Steve Jobs, Wharton School academic Jonah Berger’s new book discussing how ideas and products go viral is too derivative and too cliched to be genuinely interesting

CONTAGIOUS: Why Things Catch On, by Jonah Berger.

How has the Korean pop star Psy’s wacky horse-dance video, Gangnam Style, managed to rack up more than 1.3 billion views on YouTube? Why did a 30-minute video by a small nonprofit group calling for the capture of the Ugandan warlord Joseph Kony become a media sensation, racing across Twitter and Facebook eventually to snag the top spot on Unruly Media’s list of the 20 most shared ads on social media in 2012?

Readers might suppose that Jonah Berger’s new book, Contagious: Why Things Catch On, would shed light on these famous cases of viral content. They would be wrong. He does not explain either case.

Contagious does provide some interesting insights into factors that can help make an idea, a video, a commercial or a product become infectious, but it’s a book that remains heavily indebted to Malcolm Gladwell’s 2000 best seller, The Tipping Point, and Chip Heath and Dan Heath’s 2007 book, Made to Stick: Why Some Ideas Survive and Others Die.

Berger, an assistant professor of marketing at the Wharton School at the University of Pennsylvania, acknowledges that Chip Heath was his mentor in graduate school, and his book includes some prominent echoes of Made to Stick, including a similar Halloween-orange cover. Although Berger emphasizes the part of the equation dealing with why things go viral, many of his central arguments owe a decided debt to the Heaths’ observations about “stickiness.”


They argued that sticky ideas and products tend to be simple, unexpected and credible, with concrete details, an emotional undertow and a memorable story line. Berger, for his part, asserts that six principles help make things go viral: social currency (making people feel that they are cool insiders); triggers (everyday reminders of an item or idea); emotional resonance (making people want to share the experience with friends); observability (that is, a highly visible item advertises itself); usefulness (people like to share practical or helpful information); and storytelling (embedding a product or an idea in a narrative enhances its power).

A study he conducted of the most emailed articles in The New York Times, Berger says, showed that pieces about health and education were highly shared because of their usefulness (“Advice on how to live longer and be happier. Tips for getting the best education for your kids”) and that science articles tended to go viral because they “frequently chronicle innovations and discoveries” that evoke a feeling of awe in readers.

As Berger tells it, awe (like amusement and anger) creates a state of “physiological arousal” that goads people to take action — which apparently means, in our Internet age, forwarding a link to an article or a video.

Berger seems intent here on giving readers advice about how to create viral products — he is, after all, a professor of marketing — and he’s unfortunately adopted a ham-handed PowerPoint approach to selling his arguments. He cites studies with dubious metrics (how, for example, do you score newspaper articles “based on how much awe they evoked”); repeats things over and over, as if sheer repetition would create a kind of stickiness; and uses awful, gobbledygook terms like “self-sharing,” “inner remarkability” and “the urgency factor.”


Many of the observations in Contagious are pretty obvious to even the most casual social anthropologist. That scarcity or exclusivity can “help products catch on by making them seem more desirable” is well known to anyone who’s looked at Gilt Groupe’s business model or had a hard time locating a McDonald’s McRib sandwich. And the notion that good storytelling implants memories in listeners’ minds has been known, well, since the time of Homer.
