Texas A&M study verifies the importance of wearing masks

The politicalization of mask-wearing doesn't help stop the spread of infections.

  • A new research article concludes face masks reduced the number of infections by 78,000 in Italy and 66,000 in New York City.
  • The team writes that social distancing, isolation, and quarantining are not enough to stop the spread of COVID-19.
  • Making face masks part of the partisan culture war is not helping educate the public on virus transmission.


Pascal's wager has been on my mind.

At the risk of infuriating decision theorists, let's simplify the French mathematician's wager from the perspective of the faithful: it's better to believe in God and be wrong than to not believe and be wrong. No harm comes to believers that discover there is no afterlife (well, don't discover). Nonbelievers have some explaining to do if there is.

Let's reframe Pascal's wager in light of the pandemic. If you wear a mask and you're wrong that it protects against the virus, you're still going to get sick. The upside: if you're right, you prevent disease transmission. On the other side, refusing masks certainly does not prevent transmission. If masks are useless, no foul. But if you're wrong, well, welcome to America.

I've been wrong, many times. Here's one example: before this year, I didn't think a pandemic could be so heavily politicized. Sure, there's precedent. I falsely assumed we'd evolved as a culture. Yet wearing a mask has become a symbol of fear and submission, regardless of how many times medical experts tell us masks are a protective measure that slows transmission so we don't overwhelm hospitals.

Conflicting messages aren't helping. The toxic combination of researchers and institutions sharing unvetted findings and media outlets more concerned with breaking headlines than honoring the slow process of clinical research is adding fuel to this rampant fire.

A recent research article, led by Texas A&M University professor Renyi Zhang and published in PNAS, focuses on three COVID-19 epicenters: China, Italy, and New York City. The team concludes face masks reduced the number of infections by 78,000 in Italy and 66,000 in New York City.

"This inexpensive practice, in conjunction with social distancing and other procedures, is the most likely opportunity to stop the COVID-19 pandemic. Our work also highlights that sound science is essential in decision-making for the current and future public health pandemics."

Contributing author Mario Molina, a co-recipient of the 1995 Nobel Prize in Chemistry, says wearing a mask prevents droplets from reaching uninfected persons. He notes that droplets aren't confined to a six-foot radius; they can last in the atmosphere for tens of minutes and travel tens of feet.

Indoor conditions appear to increase the likelihood of transmission. Here in Los Angeles, gyms are reopening during the worst week of infections to date. As two mechanical engineers that specialize in HVAC systems write, while wearing PPE can be helpful, the best means for avoiding transmission is staying out of environments without natural ventilation. Being in a closed environment for more than 15 minutes with other people greatly increases the risk of infection. They conclude,

"The evidence is strong that for the foreseeable future, substituting parks, backyards or even gym driveways will be a reasonably safe way to enjoy exercise with others, while indoor workouts will remain high risk until either the risk of exposure to infection can be eliminated, or effective engineering controls can be implemented."

Of course, indoor congregation is sometimes unavoidable. In such situations, Zhang feels that mitigations such as social distancing, isolation, and quarantine are not enough to stop the rate of infection.

"We conclude that wearing of face masks in public corresponds to the most effective means to prevent interhuman transmission, and this inexpensive practice, in conjunction with extensive testing, quarantine, and contact tracking, poses the most probable fighting opportunity to stop the COVID-19 pandemic, prior to the development of a vaccine."

With nine states reporting record highs yesterday—the day Mike Pence published an op-ed in the Wall Street Journal congratulating the administration for "winning the fight" against the virus—Dr. Sanjay Gupta pushed back against the many falsities in Pence's editorial. We might think we're over with this virus, but it's nowhere near through with us.

Sadly, due to lack of national leadership, wearing a mask is a wager each one of us must make on our own. As Zhang and team point out, the data are clear. The time has come to go all-in or fold.

‘Designer baby’ book trilogy explores the moral dilemmas humans may soon create

How would the ability to genetically customize children change society? Sci-fi author Eugene Clark explores the future on our horizon in Volume I of the "Genetic Pressure" series.

Surprising Science
  • A new sci-fi book series called "Genetic Pressure" explores the scientific and moral implications of a world with a burgeoning designer baby industry.
  • It's currently illegal to implant genetically edited human embryos in most nations, but designer babies may someday become widespread.
  • While gene-editing technology could help humans eliminate genetic diseases, some in the scientific community fear it may also usher in a new era of eugenics.

FOSTA-SESTA: Have controversial sex trafficking acts done more harm than good?

The idea behind the law was simple: make it more difficult for online sex traffickers to find victims.

Has FOSTA-SESTA really lived up to it's promise of protecting sex trafficking victims - or has it made them easier to target?

Politics & Current Affairs
  • SESTA (Stop Enabling Sex Traffickers Act) and FOSTA (Allow States and Victims to Fight Online Sex Trafficking Act) started as two separate bills that were both created with a singular goal: curb online sex trafficking. They were signed into law by former President Trump in 2018.
  • The implementation of this law in America has left an international impact, as websites attempt to protect themselves from liability by closing down the sections of their sites that sex workers use to arrange safe meetings with clientele.
  • While supporters of this bill have framed FOSTA-SESTA as a vital tool that could prevent sex trafficking and allow sex trafficking survivors to sue those websites for facilitating their victimization, many other people are strictly against the bill and hope it will be reversed.
