The Sunscreen Paradox

Jul 16, 2026 · 22m

Summary

This Question Everything episode investigates the viral misinformation claiming sunscreen causes cancer, tracing it to epidemiologist Nick Holzer and Dr. Peter McCullough. They misinterpreted a UK study’s “sunscreen paradox,” where frequent users had higher cancer rates due to prolonged sun exposure, not the product itself. The hosts reveal this contrarian narrative serves to maintain audience engagement for their Substack and for-profit ventures, rather than selling specific anti-sunscreen products.
