Beyond “Check the Source”: Information Literacy for Health Decisions in the Age of AI

Elaine Kong

For decades, the golden rule of information literacy was simple: check the source. Who wrote the article? When was it published? Does the URL end in .gov or .edu?

Those questions still matter, but in today’s digital ecosystem, they are no longer enough. Modern users don’t just read static webpages; they navigate a chaotic blend of search engine snippets, algorithmic social feeds, influencer testimonials, and AI-generated summaries. In high-stakes arenas like personal health, evaluating a single “source” is no longer the primary task. The real challenge is making sense of an entire information environment.

As scholars and practitioners advocate for recognizing Information Literacy (IL) as an independent discipline, we must ask how this discipline will evolve to meet future crises. If IL is to be a discipline for the future, it has to move beyond the traditional “checklist” approach to source evaluation.

Health decision-making makes this especially clear. When a patient searches for symptom management or treatment options, they are rarely a neutral, detached researcher. They are often anxious, exhausted, or navigating intense family pressure. If a cancer survivor is toggling between a hospital portal, a Reddit support forum, and a TikTok video, simply telling them to “use credible sources” is a hollow directive. They are actively juggling clinical evidence, emotional resonance, and algorithmic visibility all at once.

To support them, the future of the IL discipline must expand to include evidence literacy. We need to help the public understand that not all evidence carries the same weight. A harrowing personal anecdote, a laboratory study, a randomized clinical trial, and a systematic review provide entirely different types of knowledge. In health contexts, an emotionally powerful claim on social media can easily overshadow a clinically reliable one. IL should give people the tools to ask: What kind of evidence is actually supporting this claim? Who was studied? Are there known risks?

Tightly coupled with this is the urgent need for uncertainty literacy. Search culture often trains people to look for “the answer,” but medicine rarely works that way. Clinical guidelines shift. A supplement might be safe for one person and risky for another because of drug interactions. Generative AI can make this problem worse by presenting answers in a confident voice, masking the messy reality of scientific consensus. Future IL must help people become comfortable asking, “How certain is this information, and what is still unknown?”

Furthermore, AI literacy can no longer be an elective; it is a core competency. Yes, generative AI can simplify medical jargon or help a patient draft questions for their oncologist. But it also blurs the critical line between a helpful explanation and professional authority. AI tools can strip away necessary context and may fail to distinguish clearly between robust clinical trials and fringe theories. We must teach users that an AI-generated health summary is never a final answer. It is a starting point that requires human verification.

Finally, we cannot discuss the future of IL without centering cultural context. As the ACRL Framework explicitly states, “authority is constructed and contextual.” People do not evaluate health data in a vacuum. Their trust is shaped by their language, migration history, family structures, and past experiences with the medical establishment, including systemic ones. A culturally responsive IL discipline doesn’t view a community’s traditional knowledge as a “barrier” to overcome; it views it as part of the context in which informed decision-making happens.

As the IL discipline matures, we must be careful not to turn information literacy into another way of blaming individuals. It is profoundly unfair to tell a patient they just need to “be a better evaluator” when trustworthy information is locked behind paywalls, buried in medical jargon, or poorly translated.

The future of IL must be both individual and structural. Yes, we must teach people how to ask better questions, but we must also challenge institutions to build better, more equitable information environments. “Check the source” was a great starting line. But if Information Literacy is truly a discipline for the future, it must teach people not just to find information, but to interrogate the invisible systems that make that information appear trustworthy in the first place.
