Making Sense with Sam Harris

Episode #436 — "A Crisis of Trust" with Michael Osterholm
Date: October 3, 2025

Overview

In this episode, Sam Harris is joined by leading epidemiologist Michael Osterholm to examine the post-COVID landscape of public health, preparedness for future pandemics, and the erosion of public trust in science. Osterholm, co-author of The Big One: How We Must Prepare for Future Deadly Pandemics, draws on 50 years of experience to discuss lessons from COVID-19, ongoing controversies around its origins and management, and the urgent need for better communication and infrastructure for the next, potentially far deadlier, pandemic.

Key Discussion Points & Insights

1. Michael Osterholm's Scientific Background (01:22–04:05)

• Osterholm’s journey: Inspired by medical detective stories in 7th grade, earning advanced degrees and founding the Center for Infectious Disease Research and Policy (CIDRAP).
• Career summary:
  • 25 years split between the University of Minnesota and the Minnesota Department of Health.
  • Involvement in every U.S. presidential administration since Reagan on infectious disease issues.
  • Authored books on bioterrorism and pandemics, notably predicting many features of COVID-19.
• Quote:

  "I've had a role in every presidential administration since Ronald Reagan… published a lot, even early on, on the issue of the potential for pandemics." — Osterholm (03:03)

2. Early Messaging Challenges During COVID-19 (04:05–07:49)

• Timeline:
  • Osterholm’s team detected Wuhan outbreak in December 2019.
  • Initially, he hoped COVID-19, as a coronavirus, would be more controllable like SARS or MERS.
  • Realization of airborne transmission changed this assessment.
• Key insight: Public and institutional resistance to early warnings; Osterholm’s prediction of U.S. deaths was met with disbelief, then vindicated.
• Quote:

  “I might as well said bad things about everybody's mother because that too was not well received... 18 months later, we were at 790,000 deaths.” — Osterholm (06:57)

3. Debates Around Airborne Transmission & Hygiene Theater (07:49–13:41)

• Airborne vs. droplet spread (08:15):
  • Osterholm describes the epidemiological distinction and uses compelling analogies.
  • Example: Story of a measles outbreak in Minnesota’s Metrodome illustrating airborne pathogenesis.
• Sam Harris’s summation:
  • If protective measures don’t block cigarette smoke, they don’t block aerosols carrying viruses.
• Hygiene theater:
  • Massive investments in ineffective plexiglass, distancing guidelines.
  • Ongoing struggle to get authorities and public to accept airborne risks.
• Need for innovation:
  • Current N95 masks are too uncomfortable for long-term use; urgent need for more practical, effective respiratory protection.
• Quote:

  “We engaged in so much hygiene theater… spent millions and millions on plexiglass shields... They provided no protection whatsoever.” — Osterholm (11:55)

• Quote:

  "If the precautions wouldn’t stop you from smelling cigarette smoke, they won’t reliably prevent aerosol transmission of a respiratory virus." — Sam Harris (11:36)

4. Lessons for the "Big One" — A More Lethal Pandemic (13:41–18:30)

• Perception of overreaction:
  • Widespread skepticism that COVID-19 response was excessive; Harris laments confusion over vaccine safety and “dogmatic” interventions.
• The real threat:
  • Osterholm underscores that much deadlier coronaviruses exist in nature with genetic potential for high transmissibility and mortality (e.g., MERS: 30–35% fatality).
• Mask innovation is a precondition for effective future response.
• Quote:

  "Right now we've identified new coronaviruses in the wild in animals that have the infectiousness of what Covid was, but it has on board also the genetic packages that could kill, like MERS and SARS." — Osterholm (16:09)

5. The Lab Leak vs. Natural Origin Controversy (18:30–20:00)

• State of evidence:
  • Both Harris and Osterholm agree: It's rational to treat lab leak and wet market origins of COVID as a “coin toss.” Fixation on this debate is an impediment to preparedness.
• Osterholm’s experience:
  • On federal oversight boards, vocal about lab safety, but believes the origin is ultimately unknowable and less important than preparing for future pandemics.
• Quote:

  “…We're never going to know. It's a coin toss. Was it a lab leak? Was it a spillover from nature? And my whole point is get over it and move on.” — Osterholm (18:53)

6. Top Three Mistakes in the U.S. COVID Response (20:00–24:34)

a) Lockdowns and Communication

• Osterholm’s early op-ed opposed broad lockdowns as unsustainable; suggested targeted “snow days” based on hospital capacity.
• Emphasized need for transparent, adaptive public guidance rather than blanket rules.
• Lockdowns were less pervasive and enduring than some critics claim—labeling policies as “lockdown” was sometimes a mischaracterization.
• Quote:

  “I wrote a piece… in early March 2020 saying, don't do lockdowns. They'll never work…” — Osterholm (20:16)

b) Understanding Transmission Mechanics

• Too slow to accept airborne transmission consensus; federal agencies lagged data-driven frontline scientists.
• Early decisions (surface cleaning, distancing) driven by incomplete understanding of transmission led to misplaced priorities.

c) Vaccine Rollout and Public Trust

• (Segment fades into the paywall at 24:51 but Osterholm begins to discuss the mRNA vaccine effort as a major achievement, yet also an area where communication failure eroded public trust.)

Summary of Tone & Language

Sam Harris is probing, skeptical, and methodical, seeking clarity about scientific uncertainty and sociopolitical reaction. Osterholm is pragmatic, expert, and occasionally wry, often pausing to reflect on institutional failures and the communication gaps that torment public health.

Final Remarks

This episode provides an in-depth, clear-eyed postmortem of the COVID-19 response, highlighting failures of communication, policy clarity, and public understanding—while warning of the existential stakes of a much worse pandemic in the future. Both speakers advocate humility, scientific literacy, and urgent innovation (especially in protective equipment), stressing that known risks in nature require action rather than endless retrospection on the last crisis.

For listeners: This conversation is essential for anyone interested in pandemic preparedness, public health skepticism, and the interplay between science, policy, and trust.
