Why game design matters for healthier outcomes At its core, public health is about driving healthy behavior changes by building awareness, meeting people where they are, and offering solutions that are accessible and grounded in evidence. Throughout my career, I have worked on issues ranging from foster adoption and drunk driving prevention to tobacco prevention and cessation, always with science as our foundation. But the media landscape, and how people engage with information, has changed dramatically. To remain relevant and effective, public health must evolve. That means rethinking not just what we communicate, but how we motivate, engage, and sustain healthy behaviors.
