“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.” (Dan Ariely, James B. Duke professor of psychology and behavioral economics at Duke University and bestselling author of Predictably Irrational)

“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.” (Chip Heath, co-author of Made to Stick and Decisive)

“Think of it as the practical companion to Malcolm Gladwell’s The Tipping Point.” (Tasha Eichenseher Discover)

“Contagious contains arresting — and counterintuitive — facts and insights. . . . Most interesting of all are the examples Berger cites of successful and unsuccessful marketing campaigns.” (Glenn C. Altschuler The Boston Globe)
"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." (Maija Palmer Los Angeles Times)
“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.” (Publishers Weekly)
