Professor John is a behavioral scientist who uses both laboratory and field experiments to investigate questions that are at the intersection of marketing, organizational behavior, and public policy.
Professor John’s work has been published in leading academic journals including the Proceedings of the National Academy of Sciences, Psychological Science, Management Science, The Journal of Marketing Research, and the Journal of the American Medical Association. It has received media coverage in outlets including the New York Times, The Wall Street Journal, Financial Times, and Time Magazine. She has received numerous awards, including from the Association for Psychological Science and the Marketing Science Institute; and was named a Wired Innovation Fellow.
Broadly, she studies how people make decisions, within two critically important domains: consumer privacy and consumer health.
Consumer privacy
Much of Professor John’s research falls in the domain of the psychology of privacy decision-making, where novel information technologies have vastly expanded our ability to share personal information. These technologies satisfy, and fuel, our innate desires for communication, interaction, and self-representation. They raise many new exciting opportunities for firms and consumers alike. But they are also fueled by large amounts of personal data, which presents a host of privacy challenges.
Professor John seeks to understand what drives people to share or withhold personal information. Beyond the interpersonal consequences of people’s decisions to share or withhold information, she seeks to understand consumers’ reactions to firms’ increasing knowledge of their personal attributes. Broadly, the goal of her research is to shed insight into how both consumers and firms alike can better navigate the digital world.
Consumer health
Escalating health care costs have focused attention on changing unhealthy but modifiable behaviors. Tobacco use, obesity, and alcohol abuse together account for nearly one-third of all deaths in the United States. Professor John has demonstrated that it is possible to exploit people’s decision biases, such as overconfidence and aversion to financial loss, to help them adopt more healthy behaviors.
