Matt Ridley discusses an NIH invitation from Jay Bhattacharya to speak on scientific freedom and argues the COVID-19 pandemic was more likely caused by a lab leak than a natural spillover, citing Wuhan research on engineered sarbecoviruses, lack of an infected animal host, and alleged cover-ups. He says scientific institutions resisted debate, harming trust in science, and notes historical lab leaks and ongoing biosecurity and bioterrorism risks. Ridley also critiques overclaims about COVID measures and vaccines and connects pandemic-driven skepticism to climate debates. He then explains themes from his books on progress and on bird sexual selection, lekking, bowerbirds, and how female choice drives beauty, plus brief Darwin and family-history anecdotes.
