The kinetic speculation is running wild as the pace of AI-driven health information delivery accelerates, outpacing the evidence needed to determine its actual impact on human comprehension, decision-making, and action. A new perspective, led by University of Alabama Professor Rebecca K. Ivic, PhD, CUNY SPH Distinguished Lecturer Scott C. Ratzan, MD, and Emory University School of Medicine Professor Emerita Ruth M. Parker, MD, is injecting a dose of reality into this chaotic landscape. They propose the concept of health-literate artificial intelligence and four principles for designing and governing AI-mediated health communication: comprehension, agency, accountability, and proportionality.
"This is the ultimate exponential build," says Ivic, "we're deploying AI into health contexts faster than we're building the evidence needed to know whether it actually helps people understand, decide, and act." As AI systems churn out answers to symptom questions, summarize health guidance, and interpret risk, the possibility of providing a technically plausible response that fails to communicate the urgency of the situation, the certainty of the information, and the need for professional care becomes increasingly likely.
The authors define health-literate AI as AI designed to align information, guidance, and responsibility with users' abilities, contexts, and needs. This framework shifts attention beyond whether AI produces information that is technically accurate or explainable to whether people can understand what that information means, make informed decisions, and determine what to do next. The four components of health-literate AI – comprehension, agency, accountability, and proportionality – provide a basis for considering whether AI-mediated communication is fit for purpose in health-relevant settings.
Ratzan, co-chair of the Nature Medicine Commission on Quality Health Information for All and editor-in-chief of the Journal of Health Communication, emphasizes the need for expert thinking, research, and analysis to protect people from potential harms while realizing the promise of this new technology for health. Parker asks, "Is AI in healthcare the holy grail or the tower of Babel?" The framework builds on decades of health literacy research that has increasingly examined not only individuals' skills but also how governments, organizations, and systems make health information easier or harder to understand and use.
Ivic proposes a novel model for today's digital information environment, examining how platforms, institutions, and emerging technologies shape the production, interpretation, and use of health information. Rather than placing the burden entirely on individuals to interpret increasingly complex automated information, health-literate AI asks how the design and governance of AI systems themselves can support understanding and informed action. The authors also challenge designers to envision how AI could help operationalize affordability of healthcare, a long-standing, well-acknowledged goal that we have not achieved.
The goal is not to make people better at navigating increasingly complex AI, but to give the field a way to begin measuring whether that is actually happening. The authors argue that health literacy should not simply require people to adapt to increasingly complex technologies. As AI becomes an increasingly important intermediary between people and health information, the systems themselves should be designed around the people who must understand and use them.
The perspective calls for adoption of the principles of health-literate AI to inform design, evaluation, research, and governance across health-relevant AI ecosystems. The authors also point to an important evidence gap: More research is needed to determine whether AI actually improves comprehension, informed decision-making, and health-related action. AI in healthcare no doubt offers opportunities for innovation, but more research, guardrails, and regulation are needed to ensure its benefits clearly outweigh its risks.
