Combating Social Media Misinformation: A Five-Step Guide

In the battle against the rising tide of medical misinformation, health experts are calling for greater vigilance and critical thinking from media consumers. Dr. Jen Gunter recently highlighted these concerns during a conversation with Professor Tim Caulfield about his new book, “The Certainty Illusion,” where they discussed practical strategies for combating the spread of health misinformation.

The timing of their discussion proved particularly poignant, coinciding with what Gunter described as “the cumulative effects of medical misinformation, conspiracy theories, and political weaponization” that resulted in the CDC advisory committee recommending against universal hepatitis B vaccination at birth in the United States.

“The science is so clear here,” Gunter emphasized. “Universal vaccination at birth has reduced the number of children with hepatitis B by more than 99%. Before we started universal vaccination in the United States, there were about 18,000 children a year being infected with hepatitis B.”

Drawing from their extensive experience researching and fighting misinformation, Gunter and Caulfield outlined five key strategies for media consumers to help stem what Gunter calls “the tsunami” of medical misinformation primarily spreading through social media and podcasts.

Their first recommendation focuses on scrutinizing content from individuals who profit from supplements. “In the United States, there is no faster, easier, or less-regulated way to make a profit in medicine than through supplements,” Gunter noted. She argued that financial incentives can significantly influence what wellness entrepreneurs, including those with medical credentials, tell consumers about health matters.

The supplement industry, largely unregulated and immensely profitable, creates what Gunter describes as a “fear-supplement ouroboros” where fear drives sales, and greater sales necessitate more fear-mongering. “Fear builds the platform; the larger the platform, the greater the sales. The greater the sales, the more fear is needed,” she explained.

The second recommendation is deceptively simple but often overlooked: read before sharing. Research cited by Caulfield indicates that 75% of posts on Facebook are shared without being read, a pattern likely similar across most social media platforms. “If it’s important enough to share, then it’s important enough to watch the whole video or read the whole post,” Gunter advised.

Their third tip involves being wary of “health halos” – terms like “natural,” “holistic,” “organic,” “chemical-free,” and “toxin-free” that create positive associations but may lack scientific meaning. Caulfield’s research shows how these words can lead consumers to fill in knowledge gaps with assumed benefits.

“A doctor or any medical professional should be able to make engaging content without relying on health halos,” Gunter noted.

The fourth strategy encourages consumers to check scientific consensus when evaluating health claims. “If content is worth sharing, it’s worth finding out where it sits in the body of knowledge and what the experts think,” Gunter advised, recommending that people search for information from established medical organizations like the American College of OB/GYN or the American Academy of Pediatrics.

Finally, Caulfield and Gunter suggest being skeptical of content that triggers strong emotional reactions, particularly those that feel like scoring points against an opposing view. Drawing on advice from misinformation expert Professor Kate Starbird, they warn that when a medical post makes you feel like “spiking the football,” it’s worth asking how much of that reaction is about ideology rather than science.

“The point of science isn’t to spike the football in someone’s face; it’s to advance knowledge and help people,” Gunter reflected.

The conversation between these experts comes at a critical time when medical misinformation has become increasingly politicized and widespread. Their practical framework offers concrete steps for individuals to better evaluate health information and avoid unintentionally spreading falsehoods.

As Gunter concluded, the fight against medical misinformation requires everyone’s participation: “While most of us contribute to the misinformation ecosystem accidentally, that also means most of us can do our part to help stop or at least reduce it.”
