Scientific breakthroughs have often depended on timing, privilege, or sheer luck. From Alexander Fleming’s accidental discovery of penicillin to Isaac Newton’s plague-era “miracle year,” history shows that chance favors the prepared mind. Yet, privilege—like that of Prince Louis de Broglie or Tycho Brahe—also played a decisive role. In stark contrast, today’s scientific progress is undermined not by fortune but by politics and misinformation. Robert F. Kennedy Jr., now U.S. Secretary of Health and Human Services, has advanced anti-vaccine conspiracy theories, opposed germ theory, and fueled deadly consequences, from Samoa’s measles deaths to threats against cancer vaccine research.
