The Catalyst: How to Change Anyone’s Mind

Professor Jonah Berger is an internationally bestselling author, and a world-renowned expert on change, influence, word of mouth, natural language processing, consumer behavior, and how products, ideas, and behaviors catch on. He has published over 50 articles in top‐tier academic journals, teaches Wharton’s most popular online course, and popular accounts of his work often appear in places like The New York Times, Wall Street Journal, and Harvard Business Review. Over a million copies of his books, Contagious: Why Things Catch On, Invisible Influence: The Hidden Forces that Shape Behavior, and The Catalyst: How to Change Anyone’s Mind are in print in over 35 countries around the world. Berger often keynotes major conferences and events like SXSW and Cannes Lions, advises various early stage companies, and consults for organizations like Apple, Google, Nike, Amazon, GE, 3M, and The Gates Foundation.

His most recent work uses automated textual analysis and natural language processing to pull behavioral insights from text data (e.g., predicting song success from lyrics, movie success from scripts, and customer satisfaction from service calls).  He co-founded the Technology and Behavioral Science Initiative and helps host an interdisciplinary conference on Behavioral Insights from Text.

    Abstract: Companies have become increasingly interested in using machine learning to aid and make decisions. But while these methods can improve prediction accuracy, and sometimes reduce human errors, we demonstrate that they often carry over biases against unprivileged groups (e.g., women and ethnic minorities) and can even intensify such biases. Consequently, this paper provides a framework to identify, quantify, and mitigate such biases. Two studies, including hundreds of thousands of loan requests, demonstrate the value of this approach. By integrating various fairness metrics and bias mitigation algorithms, our framework was able to boost fairness by 200% while keeping performance intact (Study 1) or even improving it (Study 2). Further, the studies highlight how different situations may benefit from different solutions and shed light on when different bias mitigation approaches may be more valuable. Our findings challenge the long-held belief that algorithms are fair, provide a comprehensive framework for quantifying bias, and outline a series of steps and approaches managers and leaders can use to mitigate bias.

All Courses

  • MKTG3990 - Independent Study

  • MKTG6110 - Marketing Management

    This course addresses how to design and implement the best combination of marketing efforts to carry out a firm's strategy in its target markets. Specifically, this course seeks to develop the student's (1) understanding of how the firm can benefit by creating and delivering value to its customers, and stakeholders, and (2) skills in applying the analytical concepts and tools of marketing to such decisions as segmentation and targeting, branding, pricing, distribution, and promotion. The course uses lectures and case discussions, case write-ups, student presentations, and a comprehensive final examination to achieve these objectives.

  • MKTG7680 - Contagious

    Why do some products catch on and achieve huge popularity while others fail? Why do some behaviors spread like wildfire while others languish? How do certain ideas seem to stick in memory while others disappear the minute you hear them? More broadly, what factors lead to trends, social contagion, and social epidemics? Interactive media, word of mouth, and viral marketing are important issues for companies, brands, and organizations. This course looks at these and other topics as it examines how products, ideas, and behaviors catch on and become popular. Marketers want their product to be popular, organizations want their social change initiative to catch on and entrepreneurs want their ideas to stick. This course will touch on four main aspects: (1) Characteristics of products, ideas, and behaviors that lead them to be successful. (2) Aspects of individual psychology that influence what things are successful. (3) Interpersonal processes, or how interactions between individuals drive success. (4) Social networks, or how patterns of social ties influence success.

  • MKTG8990 - Independent Study

    A student contemplating an independent study project must first find a faculty member who agrees to supervise and approve the student's written proposal as an independent study (MKTG 899). If a student wishes the proposed work to be used to meet the ASP requirement, he/she should then submit the approved proposal to the MBA adviser who will determine if it is an appropriate substitute. Such substitutions will only be approved prior to the beginning of the semester.

  • MKTG9520 - Information Processing A

    The purpose of this seminar is to provide graduate students with a solid foundation for critical thinking and research in psychology and marketing on information processing related topics.

The course draws from the literature in marketing, psychology and economics. The course will enable students to conceptualize, operationalize, and develop research ideas. Therefore, the focus is on understanding theoretical and methodological approaches to various aspects of consumer behavior, as well as advancing this knowledge by developing testable hypotheses and theoretical perspectives that build on the current knowledge base.
