Summary of: Invisible Influence: The Hidden Forces that Shape Behavior
By: Jonah Berger


Are you aware of the subtle influence others have on your everyday life? ‘Invisible Influence: The Hidden Forces that Shape Behavior’ by Jonah Berger divulges the ways in which our thoughts, actions, and even purchasing decisions are impacted by the unnoticed force of social influence. In this book, Berger discusses intriguing concepts such as mimicry, divergence, conforming to peer groups, and the quest for optimal distinction. By understanding these concepts, readers can harness the power of social influence to improve aspects of their lives, ranging from negotiations to marketing tactics.

The Power of Social Influence

Your decisions and actions are shaped by social influence more than you realize. This influence impacts your choices in what you buy, wear, and do. You may not even recognize it, but social influence affects almost every aspect of your life. The phenomenon of mimicry, consciously or unconsciously, drives purchasing choices and popularity in society. People tend to like those who are like them, including their physical traits and behaviors. This aspect can be used effectively in negotiation tactics since mimicking generates rapport and conveys that you are in the same tribe. In retail sales, mimicry leads to increased persuasion. By understanding and harnessing the power of social influence, you can influence others and be influenced in the choices you make.

The Social Impact on Your Choices

The people around us have a profound effect on our behavior, and their actions can influence our choices. From their social status to their preferences, we subconsciously form opinions about them, and this can determine what we consider worth imitating or rejecting. This phenomenon is known as “divergence” – moving away from people who do not align with our beliefs. However, we still strive to be optimally distinct, balancing our identity and integrity while seeking the acceptance of our peer group. Our decisions and actions also transmit subtle messages to others, which can lead to unexpected consequences. For instance, the way reality TV star Snooki Polizzi carried a Gucci handbag sent the brand’s perceived value plummeting among sophisticated buyers. Therefore, our actions carry weight, and we should be aware of the social impact on our behaviors.

The Force of Social Influence

Author Jonah Berger shows in his book that we tend to think we are immune to influence from others, but the truth is, social influence shapes almost every aspect of our lives. Berger’s research includes questioning BMW owners who were quick to say that they bought their cars for performance, safety, price, or aesthetic reasons. However, they gave credit to social influence for others who purchased the same car for status upgrading. Interestingly, they did not attribute their own behavior to social influence. Berger demonstrates how social influence affects our behavior without us even noticing it.

Mere Exposure Creates Liking

A psychology professor conducted an experiment where three women attended different numbers of his classes. At the end of the semester, the professor showed the students photos of these women and a fourth woman who never attended. The students rated the women on attractiveness and likability, and consistently gave the highest ratings to the woman who attended the most classes. This experiment confirms the theory that familiarity breeds liking, as many other experiments have shown before.

The Power of Groupthink

J.K. Rowling’s pen name experiment highlights the influence of groupthink and conformity on decision-making. Groupthink occurs when the desire for harmony takes precedence over individual thoughts, leading to less diverse thinking. Rowling’s book, published under a pen name, received lukewarm reviews until her real identity was revealed. Suddenly, the book became a bestseller as people bought it because other people did. This example illustrates the power of mimicry and familiarity in generating liking. To avoid groupthink, we need to encourage independent thinking and diverse opinions.
