In this compelling podcast episode, NIH Director Dr. Jay Bhattacharya sits down with A16Z Health and Bio general partners to discuss his transformative vision for American biomedical research. The conversation centers around three major announcements: a groundbreaking $50 million autism research initiative involving 13 funded teams, new clinical insights on leucovorin (an old drug showing promise for autism treatment), and revised guidance on acetaminophen use during pregnancy. (01:07)
• Main Theme: Rebuilding public trust in science through rigorous research, supporting early-career investigators, and addressing America's most pressing health challenges including autism, chronic diseases, and stagnant life expectancy rates.
Dr. Jay Bhattacharya serves as Director of the National Institutes of Health (NIH), bringing extensive academic credentials from Stanford University where he worked as a professor. He has published over 180 peer-reviewed papers and gained national recognition for his advocacy of academic freedom and evidence-based policy making. His leadership philosophy emphasizes rigorous science, replication studies, and rebuilding public trust in biomedical research.
Vinita Agarwal is a General Partner at Andreessen Horowitz (a16z) focusing on Health and Bio investments. She brings expertise in evaluating and supporting healthcare innovations and biomedical technologies.
Jorge Conde serves as a General Partner at Andreessen Horowitz (a16z) in the Health and Bio practice, specializing in biotechnology and healthcare investments with deep knowledge of drug discovery and clinical development.
Dr. Bhattacharya argues that the NIH must adopt Silicon Valley's portfolio approach to risk-taking. (10:46) He explains that venture capital firms succeed by expecting 49 out of 50 investments to fail, as long as the 50th becomes a breakthrough like Google. Similarly, the NIH should stop punishing scientists for productive failures and instead encourage them to publish their learnings. This cultural shift requires moving away from the conservative peer review system that has dominated biomedical research for decades, where established scientists often reject novel ideas that challenge their own work.
The data reveals a troubling trend: in the 1980s, scientists received their first major NIH grants at age 35, but today that age has shifted to the mid-40s. (25:39) Bhattacharya's research shows that ideas age by one year for every chronological year, except for Nobel Prize winners who fight to keep their thinking fresh. To combat this, the NIH is restructuring incentives to reward institute directors who support early-career investigators and evaluating senior scientists based on how well they mentor the next generation.
The pandemic severely damaged public trust in science and public health institutions. (38:05) Bhattacharya identifies the root cause as scientists conveying false certainty about uncertain matters while implementing policies that lacked scientific backing. The solution requires two elements: returning to gold standard science with proper replication and peer review, and adopting a servant attitude toward the public rather than an authoritative stance. When facing uncertainty, scientists must honestly say "I don't know" and explain their process for finding answers.
A replication crisis has plagued science for two decades, where published findings often cannot be reproduced by independent teams. (06:14) Bhattacharya explains this stems from science becoming too specialized and voluminous, with no career incentives for checking others' work. The NIH is now investing heavily in replication studies because the standard for scientific truth should be independent confirmation, not just publication in a peer-reviewed journal. This shift requires changing how scientific careers are evaluated and rewarded.
Despite massive biomedical research investment, U.S. life expectancy has stagnated for over a decade while chronic diseases like diabetes, heart disease, and autism continue rising. (22:24) Bhattacharya argues this reflects misaligned research priorities that favor incremental advances over addressing the diseases that most burden Americans. The solution requires both political input on research allocation and scientific expertise on execution, ensuring NIH funding targets the conditions causing the most suffering while supporting breakthrough research approaches.
