Invisible Influence

March 21, 2016
Expanding on the ideas explored in his 2013 bestseller, Contagious, Berger offers an engaging guide to the concept of social influence. He examines how opposing categories of socially motivated behavior—imitation and differentiation—combine to create complex cultural patterns. He shows, for example, the imperceptible communal nudges behind baby-naming trends, racial achievement gaps, and group decision-making at work. Though Berger teaches marketing, his book appeals to readers beyond the M.B.A.s. Ultimately, the focus is on applied psychology. “We like things that are moderately similar,” he says, “blending the allure of novelty with the comfort of the familiar.” Some of his points are familiar from Psychology 101: familiarity increases attraction, stereotypes are shortcuts used to process new information. But unlike the writing in the average psych textbook, Berger’s prose is consistently entertaining, applying science to real life in surprising ways and explaining research through narrative. He can be repetitive, and his stylistic brevity becomes distracting: sentence fragments are overused. Still, it makes for good retention. Social influence is an intricate subject, but Berger simplifies without patronizing. His book fascinates because it opens up the moving parts of a mysterious machine, allowing readers to watch them in action.

Using compelling storytelling and drawing on research from the fields of education, psychology, and other social sciences, Berger's (marketing, Wharton Sch., Univ. of Pennsylvania; Contagious) eye-opening book offers insights into how human behaviors are influenced by social forces such as imitation, differentiation, conformity, avoidance, and combinations of these factors. The author argues that these elements impact choices ranging from trivial decisions to important life events. He then expands upon his theories to show how cultural authorities shape aspects of business, such as markets, operations, products and services, and technological uses and innovations. These powers affect business decision making, including careers; human resources; and consumer perceptions, preferences, and purchasing. VERDICT Berger's unique knowledge will appeal to readers from many backgrounds, especially individuals interested in making better decisions. Suitable for both academic and public library business collections.--Caroline Geck, Camden Street Sch. Lib., Newark, NJ
