Told You So! with Matt Kaplan

In this special edition of StarTalk Radio, Neil deGrasse Tyson and guest Matt Kaplan explore the often-overlooked history of scientists who were ridiculed, exiled, or imprisoned for being right—only to be vindicated posthumously. From Galileo’s diplomatic maneuvering to avoid torture despite challenging Church doctrine, to Ignaz Semmelweis’s tragic fate after discovering that handwashing could prevent childbed fever, the episode reveals how scientific progress has been repeatedly stymied by institutional resistance, ego, politics, and economic interests. The story of Louis Pasteur, a brilliant but ethically questionable figure who stole credit from predecessors like Henry Toussaint and Pierre Gaultier, underscores how personal ambition can corrupt scientific integrity. The narrative culminates with Katalin Kariko, whose decades-long struggle to secure funding for mRNA research—despite being demoted and threatened with deportation—ended in a Nobel Prize and the rapid development of the COVID-19 vaccine. The episode argues that while skepticism and debate are essential to science, the dismissal of ideas through character assassination, bias, or systemic gatekeeping undermines progress. The key takeaway is that science must be transparent, inclusive, and better communicated to the public to rebuild trust in an era of anti-science sentiment.
