“Jonah Berger is as creative and thoughtful as he is spunky and playful. Looking at his research, much like studying a masterpiece in a museum, provides the observer with new insights about life and also makes one aware of the creator's ingenuity and creativity. It is hard to come up with a better example of using social science to illuminate the ordinary and extraordinary in our daily lives.”
“If you are seeking a bigger impact, especially with a smaller budget, you need this book. Contagious will show you how to make your product spread like crazy.”
“Why do some ideas seemingly spread overnight, while others disappear? How can some products become ubiquitous, while others never gain traction? Jonah Berger knows the answers, and, with Contagious, now we do, too."
“Jonah Berger knows more about what makes information ‘go viral’ than anyone in the world.”
“Jonah Berger is the rare sort who has studied the facts, parsed it from the fiction—and performed groundbreaking experiments that have changed the way the experts think. If there’s one book you’re going to read this year on how ideas spread, it’s this one.”
“Think of it as the practical companion to Malcolm Gladwell’s The Tipping Point.”
“[Berger] sheds new light on phenomena that may seem familiar, showing with precision why things catch on. . . . As a playbook for marketers, Contagious is a success.”
“Contagious contains arresting — and counterintuitive — facts and insights. . . . Most interesting of all are the examples Berger cites of successful and unsuccessful marketing campaigns.”
"For nonexperts who puzzle about the best way to make an impact in a world of social media addicts with short attention spans, it provides plenty to think about. . . . If there were a 'like' button underneath it, you'd probably find yourself clicking it."
“An infectious treatise on viral marketing. . . . Berger writes in a sprightly, charming style that deftly delineates the intersection of cognitive psychology and social behavior with an eye toward helping businesspeople and others spread their messages. The result is a useful and entertaining primer that diagnoses countless baffling pop culture epidemics.”
“The book is just plain interesting. Berger’s cases are not only topical and relevant, but his principles seem practical and are easily understood. . . . I have a strong feeling that this book will catch on.”

"A provocative shift in focus from the technology of online transmission to the human element and a bold claim to explain 'how word of mouth and social influence work . . . [to] make any product or idea contagious."
