You've seen these claims on your feed. Raw milk is healthier. Vaccines cause more harm than good. Fluoride is poisoning our water. And somewhere in the back of your mind, you've thought: Only uneducated people fall for this stuff.
A global survey just shattered that assumption. The 2026 Edelman Trust Barometer surveyed sixteen thousand people across sixteen countries about six debunked health claims. The headline finding? Seventy percent of people worldwide believe at least one of them. Not fringe conspiracy theorists. Not the deliberately ignorant. Seven in ten humans on this planet.
But here's where it gets uncomfortable. When researchers split the data by education level, they found almost no difference. College graduates believe these myths at sixty-nine percent. People without degrees? Seventy percent. One percentage point. That forty-thousand-dollar degree buys you exactly one percent less susceptibility to health misinformation.
The Myths People Actually Believe
Edelman tested six specific claims—all thoroughly debunked by scientific consensus. The results paint a picture of widespread confusion.
"The risks of childhood vaccines outweigh the benefits." Between twenty-five and thirty-two percent agreed. That's roughly one in four people contradicting decades of immunology research.
"Fluoride in drinking water is harmful to human health." Same range—a quarter to a third of respondents, despite mountains of dental research proving fluoridation's safety and effectiveness.
But the raw milk finding demands special attention. A quarter of the global population believes unpasteurized dairy is healthier than pasteurized—and this belief is actively harming people. In 2025, at least twenty-one people in Florida became severely ill after drinking raw milk. Six were children. The culprits: E. coli and Campylobacter, both eliminated by the pasteurization process Louis Pasteur invented in 1864 specifically because raw milk was killing people.
Here's the number that should end this debate: unpasteurized dairy is responsible for about ninety-five percent of all milk-related illnesses. An eight-hundred-fold greater risk than pasteurized products. Yet the "natural is better" narrative persists.
Why Education Fails as a Shield
The Edelman report puts it bluntly: "Doubts about nutrition, vaccination, and public safety recommendations are no longer a fringe view. They stem neither from a single ideology nor lack of education."
So what's actually happening? The researchers point to something called "authority transfer." A claim appears with official-sounding language—"NASA confirmed" or "Harvard study shows"—and the authority of the institution transfers to the claim, even when the institution never said it. Your brain shortcuts the verification process. You see the authority marker, assume the claim was vetted, and scroll on. It happens in milliseconds, too fast for critical thinking to engage.
Social media amplifies this exponentially. When fifteen friends share a claim, your brain processes that as fifteen endorsements—even if none of them verified it either.
And here's the part nobody wants to acknowledge: education might actually make things worse in some ways. Studies on motivated reasoning show that the more educated you are, the better you become at constructing arguments for things you already believe. A degree doesn't make you more objective—it makes you more skilled at rationalization.
The Trust Problem Nobody Wants to Discuss
The pandemic created a credibility crisis that's still unfolding. Scientists communicated poorly, changed guidance repeatedly, and sometimes got it flat wrong. When health authorities said masks don't work, then said they do, then added exceptions and caveats—people remembered. And they should have.
Some credentialed skeptics turned out to be right about some things. The lab leak hypothesis. Myocarditis risks in young men. The limitations of cloth masks. When the official narrative gets things wrong—and it did—people extrapolate. They assume if authorities were wrong about X, maybe they're wrong about Y and Z too. It's pattern matching, not irrationality.
The data varies dramatically by country. India and South Africa show the highest rates—eighty-nine and eighty-eight percent respectively believing at least one debunked claim. Japan sits lowest at around fifty percent, with Canada and the US between fifty and sixty-one percent. Even in the best-performing countries, half the population believes medical misinformation.
And it's not partisan. Vaccine skepticism trends conservative, but "natural is better" beliefs—organic everything, chemical-free living, raw milk enthusiasm—trend progressive. Misinformation isn't a left or right problem. It's a human problem.
What Actually Works
The Edelman researchers found something counterintuitive: transparent uncertainty builds trust. When scientists say "we don't know yet," that's more credible than false confidence. After years of overconfident claims that aged poorly, humility actually increases credibility.
But institutional change is a generational project. In the short term, you're your own best defense. That means doing the unglamorous work:
Check the actual source before sharing anything health-related. Not the headline. Not the tweet. The actual study or official statement.
Be skeptical of claims that feel satisfying. Raw milk feels natural. Fluoride sounds like a chemical additive. Vaccine skepticism feels like healthy questioning. The feeling of truth and actual truth are different things entirely.
Follow the money. Raw milk advocates often sell raw milk. Supplement promoters sell supplements. Identifying incentives helps.
Actively seek the strongest argument against your current belief. Not a straw man—the actual best case. If you can't steelman the opposing view, you don't understand the issue well enough.
The Myth That Matters Most
Seventy percent of people believe at least one debunked health claim. The question isn't whether you're in that seventy percent. The question is whether you're willing to find out which lie is yours.
And if you think you're immune because you went to college? That might be the most dangerous myth of all. Education gives you better tools for defending beliefs you already hold—it doesn't automatically point those tools at yourself.
Misinformation isn't primarily an information problem. It's a trust problem. And trust gets rebuilt one honest conversation at a time—starting with the one you have with yourself about what you might be wrong about.
