Del Bigtree, a longtime ally of Robert F. Kennedy Jr., isn’t just anti-vaccine. He’s pro-infection.

Over coffee at a Starbucks just outside Austin, Texas, Del Bigtree told me he wants his teenage son to catch polio. Measles, too. He’s considered driving his unvaccinated family to South Carolina, which is in the midst of a historic outbreak, so that they can all be exposed. He prefers pertussis—whooping cough—to the pertussis vaccine, which he later described to me as a “crime against children.” It’s not the diseases that Americans should be afraid of, Bigtree insists: It’s the shots that stop them.

Spreading that message is Bigtree’s lifework. He produced Vaxxed: From Cover-Up to Catastrophe, a 2016 documentary that helped mainstream the modern anti-vaccine movement by alleging—spuriously—that the CDC suppressed evidence of vaccine harms. His weekly internet show, The HighWire With Del Bigtree, mostly targets the pharmaceutical industry and has helped raise millions for his nonprofit, the Informed Consent Action Network, which files lawsuits to overturn school vaccine mandates around the country. He’s been a close adviser to Health Secretary Robert F. Kennedy Jr. and served as communications director for Kennedy’s 2024 presidential campaign.

    That theory has been challenged.

    Discussion

    DeSilva et al. (2021) propose that human brain size has decreased, and offer innovative reasons why this may be so, primarily focusing on a model of “group level cognition.” Our analysis of these data fails to find a decrease in human brain size over the last few thousands of years. When the large sample sizes of the most recent human samples are adjusted for, the pattern disappears, and the arguments no longer need to be invoked.

    We argue that, when examining questions of micro-evolutionary change, the analysis and data need to be appropriate for the specific scale of that hypothesis. Further, the data need to be otherwise relevant for the hypothesis being tested (see Houle et al., 2011). Given that the adoption of agriculture and the transition to complex societies occurred in different times at different places, the samples need to be specific enough to test the hypothesis across different times and populations, which does not appear to be the case in this instance.
