Why RFK Jr. Is Wrong About Autism—and Why It’s Dangerous

Okay, so let’s talk about something that’s been making headlines lately: Robert F. Kennedy Jr. and his claims about autism. He’s been out there saying that autism is an “epidemic” caused by environmental toxins, not genetics. He’s even pledged that, if he’s in charge of the Department of Health and Human Services, he’ll figure out what causes autism by September. That might sound bold and ambitious, but honestly, it’s scientifically off-base—and kind of dangerous.

Let’s be clear: the overwhelming evidence says that autism is mostly genetic. Like, we’re talking 80 to 90 percent of the risk is tied to genes. Researchers have looked at twin studies, family history, and all sorts of genetic data to reach that conclusion. But RFK Jr. doesn’t want to hear it. He says we should stop studying genetics and focus on environmental stuff like chemicals or vaccines (yes, he’s still dancing around that old, debunked claim). That’s not just wrong—it’s misleading. The rise in autism diagnoses isn’t because something terrible suddenly poisoned all our kids. It’s mostly due to better awareness, updated diagnostic criteria, and more people getting the help they need.

But here’s where it gets really concerning: if someone like RFK Jr., who pushes these ideas, ends up running the country’s health department, we’ve got a real problem. First off, it could lead to cutting funding for important genetic research—research that could actually help autistic people live better lives. Second, it spreads fear and misinformation. Talking about autism like it’s a “tragedy” or an “epidemic” makes life harder for autistic people and their families. It adds shame where there should be support and understanding. And don’t even get me started on the vaccine stuff—undermining public trust in vaccines could seriously hurt public health.

In the end, leadership in healthcare has to be grounded in facts, not conspiracy theories or fringe beliefs. RFK Jr. might mean well, but his views on autism are not supported by science. And when you’re in charge of millions of people’s health, meaning well isn’t enough—you need to be right. Otherwise, real people pay the price.
