Half of Americans Now Use Artificial Intelligence for Medical Advice
Framework
What CAIHL does
Critical AI Health Literacy (CAIHL) is an analytical lens — Hugo Campos and Liz Salmi's 2025 National Academy of Medicine commentary, "Critical AI Health Literacy as Liberation Technology." It applies Paulo Freire's theory of critical literacy to health AI.
The central question CAIHL asks is whose interests does this AI actually serve? Four dimensions answer it: who is the primary user, where is it hosted, whose interests does it advance, and does it expand or constrain patient agency.
This deep-read separates the four dimensions on a single item from the day's scan, so you can see the specific structural shape of the AI in question — not just the bucket it landed in.
The four dimensions
How this item reads through CAIHL
Primary user
patient
Patients, families, and care partners are the primary users of this AI.
Hosting
public
Hosted for public use (ChatGPT, Claude, consumer apps). Anyone with a device can use it.
Interests
patient-aligned
Interest structure prioritizes patients. Operates on a philanthropic, public-service, or advocacy footing.
Agency
expanding
Expands patient capabilities, supports their questions, increases their ability to act on their own values across and beyond health systems.
Editor's CAIHL read
One-sentence synthesis
Population-prevalence figure crossing the 50% threshold; expanding patient agency by making the practice statistically dominant.
In the scan
How this item appeared in the daily scan
Editor's note: Half-population prevalence is the threshold past which 'patients use AI' stops being a behavioral story and becomes an infrastructure story. The next AI medical-advice survey has to start with explaining what fraction of the country doesn't.
Summary: geneonline.com: Survey reporting that approximately half of US adults now consult AI tools for medical advice — the broadest population-prevalence figure yet published in any US-jurisdiction sample.
methodology
Limitations
CAIHL is a lens, not a verdict. The four dimensions are conditions of use — reassess them when a tool's business model, deployment context, or patient behavior changes. See the NAM commentary for the full framework.
