Does RFK Jr. Know the Scientific Method?
 September 22, 2025 Greetings, Meteor readers, We are closed tomorrow in observance of Rosh Hashanah, but we couldn’t let you go into the week without your favorite newsletter! But before we take a little rest, let’s talk about Tylenol. Raw dogging our headaches, Shannon and Mattie  WHAT’S GOING ONFor the past two weeks, news has been swirling that the Department of Health and Human Services is expected to announce a potential link between pregnant people’s use of Tylenol and a supposed increased risk of autism in children. Those reports intensified over the weekend, and senior officials are now briefing media outlets on background. The timing makes perfect sense for exactly one person and no one else: That would be HHS Secretary Robert F. Kennedy Jr. Yes, the same man who is imperiling millions of children with his documented anti-vaccine agenda and has admitted to having a literal brain worm. Several months ago, he said that he intended to find the root causes of autism before the end of September. With October on the horizon, he must be feeling the pressure. So here we are. The expected new guidance—which is expected to drop before the end of the week—will tell pregnant women not to use Tylenol except in cases of high fevers, robbing them of one of the few options they have to manage pain for the 40 weeks they spend growing another human. (Doctors have long recommended Tylenol, the name brand for the generic acetaminophen, because similar fever reducers and pain relievers like Ibuprofen, the generic drug behind Advil, have a documented association with miscarriage and potential fetal harm.) The obvious question, of course: Is Tylenol dangerous? While some limited research has suggested a possible association between Tylenol consumption and autism, larger studies—including a recent and major examination of the outcomes of 2.5 million children in Sweden—have turned up no connection. And the American College of Obstetricians and Gynecologists recently affirmed the recommendation of Tylenol in a recent statement to CBS News, telling the outlet that “there is no clear evidence that proves a direct relationship between the prudent use of acetaminophen during pregnancy and fetal developmental issues.” The prevalence of autism has increased over the past 25 years, according to CDC statistics, with a range of possible explanations. One that we know to be true is that the definition for what constitutes the condition has changed and expanded, making it easier to be diagnosed (and to access services). What we also know to be true? The drug Tylenol has been available over the counter for almost 70 years—well before the documented growth in cases. So scientists, researchers, and those who can count agree: Tylenol is not the likeliest culprit for the increase in autism rates. They reach that conclusion via the scientific method, which isn’t just a unit in high school curricula. It’s an actual process that actual scientists respect. It involves investigating observable phenomena through rigorous testing and careful experimentation. It does not involve setting self-imposed deadlines and drumming up questionable research to meet them. But there is no doubt that this announcement will confuse pregnant women, their providers, and their families. It will, in all likelihood, make those who are experiencing pain while pregnant (that’s 100% of pregnant people, FYI) hesitate before treating it, wondering if their degree of discomfort justifies a dose of relief. (Even though we know that stress and pain can themselves lead to adverse outcomes for babies, including preterm birth, low birth weight, high blood pressure, and other complications.) This announcement will not make pregnant women or children safer or healthier, but it will sow more doubt in the medical establishment, and it will make women suffer. — Mattie Kahn AND:
