In an episode of The Joe Rogan Experience, Robert F. Kennedy Jr. made numerous scientifically debunked claims, including the alarming assertion that WiFi radiation causes cancer and opens the blood-brain barrier.
The appearance has drawn sharp criticism from scientists, with molecular biologist Dr. Wilson systematically dismantling Kennedy’s arguments in a detailed video response.
When Kennedy claimed that “WiFi radiation does all kinds of bad things including causing cancer,” and that he’s “representing hundreds of people who have cell phone tumors behind the ear,” he was spreading misinformation that contradicts established physics.
As Dr. Wilson explained, radiation exists in two categories: ionizing and non-ionizing. Ionizing radiation, like X-rays, is strong enough to break DNA bonds and cause cellular damage that can lead to cancer. Non-ionizing radiation, which includes WiFi and radio waves, lacks this capability entirely.
WiFi radiation simply isn’t powerful enough to penetrate skin and tissues, let alone damage DNA. When Rogan asked Kennedy to explain how WiFi radiation “opens up your blood-brain barrier,” Kennedy stumbled over his words and couldn’t provide a coherent answer—because no such mechanism exists in scientific literature.
This WiFi fearmongering formed just one part of a three-hour conversation filled with what Dr. Wilson characterized as “an absolute tsunami” of anti-vaccine misinformation. Kennedy falsely claimed that no vaccines undergo placebo-controlled trials before approval, despite the fact that every first vaccine, from the 1954 polio trials to recent COVID vaccines, has been tested in randomized, double-blind, saline placebo-controlled studies.
Perhaps most disturbing were Kennedy’s claims about the 1918 Spanish Flu pandemic, which he suggested was “vaccine induced.” This theory ignores basic medical history—flu vaccines didn’t exist in 1918. The deaths Kennedy referenced were caused by secondary bacterial pneumonia, a well-documented consequence of influenza virus infection that strips the body’s respiratory defenses.
Kennedy also misrepresented the science on thimerosal (a mercury-containing preservative once used in vaccines), claimed that aluminum adjuvants are “horrendously toxic,” and perpetuated the thoroughly debunked link between vaccines and autism. Multiple large-scale studies across different countries and populations have found no association between vaccination and autism spectrum disorders.
Dr. Wilson expressed particular frustration that Rogan, whose podcast reaches more listeners than any other, failed to fact-check even Kennedy’s most easily debunked claims. “What are we doing here?” Dr. Wilson asked after Kennedy made the false claim that vaccines are exempt from placebo-controlled trials. “Joe Rogan’s podcast is the most listened to podcast in the world and he has said repeatedly that he will try to make his show better about spreading misinformation.”
The danger of platforming such misinformation extends beyond abstract concerns about scientific accuracy. Kennedy’s rhetoric has real-world consequences, from discouraging pregnant women from getting flu shots to promoting vaccine hesitancy that can lead to preventable disease outbreaks.
As Dr. Wilson noted, Kennedy’s book even praised Christine Maggiore, an HIV/AIDS denialist whose rejection of antiretroviral treatment led to both her own death and that of her daughter from AIDS-related complications.
Scientists worldwide have spent decades researching and answering the very questions Kennedy raises, consistently finding that vaccines are remarkably safe and effective at preventing disease. The evidence is publicly available in peer-reviewed literature, yet Kennedy continues to ignore it in favor of conspiracy theories and long-debunked claims—now amplified to millions through Rogan’s platform.
