Contingency management—where individuals earn privileges (like private shelter rooms) by passing drug tests, and lose those privileges upon relapse (but retain shelter access)—is an evidence-based addiction treatment approach supported by research from Birmingham, Alabama and accepted even by harm-reduction advocates like the Drug Policy Alliance.

The 10,000 steps per day target was picked arbitrarily by a Japanese pedometer company in the 1960s based on what 'sounded auspicious,' not on scientific evidence. Epidemiological data shows that health benefits plateau around 7,000–8,000 steps per day; hunter-gatherers average 10,000–18,000 steps depending on sex, suggesting the metric is reasonable but not optimal.

Only 50% of Americans ever exercise, and only 20% meet minimal World Health Organization physical activity standards; the rest of the world is following the American pattern.

If given a blank canvas to redesign modern society for health, one would ban white bread and elevators (except for accessibility), making people walk stairs and eat whole grains. While this would improve long-term health and happiness, liberty and choice must be respected. Better approaches: tax sugar, advertise healthy foods as heavily as unhealthy foods, make healthy food cheap as unhealthy food, sponsor community dancing.

Dancing is a form of physical activity that is social, fun, and engaging. Communities worldwide have dancing traditions. Why don't towns sponsor weekly community dances? This would improve physical and mental health at population scale, yet it's absent from public health policy.

The primary recommendation for public health is to reduce blue light and increase red light in environments, rather than optimize across all wavelengths; Glenn states he would 'die happily' if able to remove blue and restore red, even without comprehensive full-spectrum replication.

Shelf placement of candy at child eye-level in grocery stores is a deliberate corporate manipulation; moving candy to higher shelves reduces accessibility and creates a counter-nudge.

Advertising bans on unhealthy foods (like Captain Crunch and Cocoa Puffs) targeted at children can remove the advertising seduction that corporations currently use to drive consumption.

Education campaigns telling people to make healthy food choices do not work in practice; 48% of Americans still drink sugary drinks daily despite widespread knowledge of health risks.

Effective public health interventions do not rely on individual choice or education; instead, they 'nudge' populations away from unhealthy options by making them less convenient, visible, or affordable—essentially flipping the corporate strategy.

Small environmental changes can accumulate into large population-level shifts in behavior and health outcomes, as demonstrated by decades of research on how to counter addictive substances.

We have the capacity and knowledge to redesign the food environment to be safe and healthy, rather than remaining in a system rigged to make us fat while blaming individuals for health consequences.

Sports celebrities who endorse Gatorade and other sugary drinks could alternatively be paid to promote water consumption, creating a counter-nudge to celebrity endorsement strategies.

The most effective way to reduce tail risk in a contagion process is to reduce connectivity and movement (through travel restrictions and quarantines), which directly lowers the scale of the tail distribution by cutting off the distribution of contagion outcomes.

The designated driver social innovation, incubated at Harvard School of Public Health, likely saved as many lives as massive amounts of biological research

The worry with COVID is not only that we have not learned lessons but that we have got a 'vaccine injury' from the experience: vaccine skepticism has increased and everyone is stuck in their own corner with their own facts.

High school seniors' outbreak parties and post-Memorial Day spikes in cases demonstrate that outdoor protest transmission risk is uncertain, but the precedent shows second wave risk is real and states with 7-day moving averages exceeding previous levels (Texas, Florida, Arizona, Utah) are seeing rapid case increases

Hong Kong's grassroots compliance with masks (despite government advice against them) and one-time leaders' poor initial guidance resulted in only 1-4 deaths and continued economic functioning without shutdowns, demonstrating that voluntary coordination can work better than mandates or mixed signals

Barry Ritholtz discussed how Sweden's laissez-faire pandemic approach (letting it run its course) resulted in economic damage equivalent to shutdown countries, while also having case count increases—proving that economic damage was unavoidable regardless of policy choice

The coronavirus will likely infect approximately 60% of the population before becoming endemic, and with the population currently at 5% infection, the disease could become something people learn to live with rather than fear, changing economic behavior permanently

Life outcomes differ dramatically by education level: high school graduates live 8 years shorter than college graduates; 40% of high school grads are obese vs 20% of college grads; high school grads marry less and divorce twice as often; 60% of births to high school-educated women happen out of wedlock vs a rate 20 times lower for college-educated women; opioid death rate is 10 per 100,000 for high school grads vs 2 per 100,000 for college grads.
