Algorithms, attention, and trust: Rethinking health communication with Matthew Kreuter

The techniques that make health messages more effective—personalization, customization, targeted delivery—are the same tools driving the spread of inaccurate health claims at scale. Dr. Matthew Kreuter, WashU’s Kahn Family Professor of Public Health and founding director of the Health Communication Research Laboratory, is an expert on effective and equity-oriented health communications and has been thinking about these issues for decades.

In this episode, Salma and Dr. Kreuter trace the evolution from pamphlet racks to algorithm feeds. They discuss why well-intentioned public health messaging can backfire and highlight the importance of listening. They explore why certain terms have become counterproductive, the costs of communicating false certainty, and why public health can’t message its way out of complex problems.

Tune in for a candid discussion about the double-edged nature of communication in the algorithm age, and why the future of health communication may depend less on what we say than on how well we listen.
