Sean Mullen, Ph.D. @drseanmullen.bsky.social · 11/06/2026Respirators in social settings work extremely well and allow one to avoid infections for years…as I have. There is NO way I would not take that option. I have a family & there are things I want to do in life. I don’t succumb to peer pressure. Is this high school? People are DYING from Long Covid. 1416447
Sean Mullen, Ph.D. @drseanmullen.bsky.social · 27/05/20261/ Public health has become overly insular and insufficiently interdisciplinary. I work in applied health science. What I don’t have is indoctrination into decades of droplet-era institutional inertia. That’s the difference. 15311

Sean Mullen, Ph.D. @drseanmullen.bsky.social · 27/05/20261/ Please put aerosol scientists and engineers back in charge of public health. We built infectious disease policy around outdated droplet assumptions while ignoring aerosol physics, ventilation, and indoor air quality. 126179
Sean Mullen, Ph.D. @drseanmullen.bsky.social · 26/05/20261/ Public health has an education problem. Airborne transmission is still incorrectly described — or omitted entirely — in many Master of Public Health programs and the textbooks used to train future professionals. 613747

Reposted by Sean Mullen, Ph.D.Mark Ungrin @mark-ungrin.bsky.social · 25/05/2026The problem is almost none of the people in these decision making positions has much of an understanding of science, and they're all trained to think that absence of evidence = evidence of absence. And since the entire GRADE pyramid is purely reactive, the only evidence they accept is dead bodies. 0214

Sean Mullen, Ph.D. @drseanmullen.bsky.social · 24/05/2026Higher ed is going to spend the next decade pretending nothing is wrong with student cognition except “use of AI.” By the time the data is undeniable, the cohort will be in their 30s, wondering why everything feels so hard. 0564
Sean Mullen, Ph.D. @drseanmullen.bsky.social · 24/05/2026Cognitive fatigue is real. We mock it because admitting it would force us to redesign everything: schools, workplaces, classrooms, hospitals, parenting. Mocking is cheaper. 06511
