STORY AT-A-GLANCE- Not a single randomized controlled trial with verified outcome has been able to detect a statistically significant advantage of wearing a mask versus not wearing a mask, when it comes to preventing infectious viral illness

If there were any significant advantage to wearing a mask to reduce infection risk to either the wearer or others in the vicinity, then it would have been detected in at least one of these trials, yet there's no sign of such a benefit There is no evidence that masks are of any utility for preventing infection by either stopping the aerosol particles from coming out, or from going in.

You're not helping the people around you by wearing a mask, and you're not helping yourself avoid the disease by wearing a mask

Infectious viral respiratory diseases primarily spread via very fine aerosol particles that are in suspension in the air. Any mask that allows you to breathe therefore allows for transmission of aerosolized viruses

All-cause mortality data are not affected by reporting bias. A detailed study of the current data of all-cause mortality shows the all-cause mortality this past winter was no different, statistically, from previous decades. COVID-19 is not a killer disease, and this pandemic has not brought anything out of the ordinary in terms of death toll

Denis Rancourt, Ph.D., a former full professor of physics, is a researcher with the Ontario Civil Liberties Association in Canada. He’s held that volunteer position since 2014, which has given him the opportunity to dig into scientific issues that impact civil rights. He also did postdoctoral work in chemistry.

Here, we discuss the controversial topic of face masks. Should you wear one? When and where? Does it protect you or not? There’s a wide range of opinions on this even within the natural health community.

Early on in the COVID-19 pandemic, I endorsed the use of face masks based on the experience of some of the Eastern European countries. The rationale of it seemed to make sense at the time. Since then, however, I’ve started to question their use.

Unfortunately, the mainstream propaganda and government orders in many states in recent weeks have reverted back toward mask wearing just about everywhere. You’re not allowed into stores; you cannot fly or take a cab, Uber or Lyft without one; you must wear one everywhere you go, even outdoors, and if you don’t you’re vilified, sometimes aggressively attacked.

NONE of these well-designed studies that are intended to remove observational bias found a statistically significant advantage of wearing a mask versus not wearing a mask.

There’s No Scientific Support for Mask-Wearing

Rancourt’s investigation into mask wearing was part of his research for the Ontario Civil Liberties Association. He did a thorough study of the scientific literature on masks, concentrating on evidence showing masks can reduce infection risk, especially viral respiratory diseases.

“What I found when I looked at all the randomized controlled trials with verified outcome, meaning you actually measure whether or not the person was infected … NONE of these well-designed studies that are intended to remove observational bias … found there was a statistically significant advantage of wearing a mask versus not wearing a mask.

Likewise, there was no detectable difference between respirators and surgical masks. That to me was a clear sign that the science was telling us they could not detect a positive utility of masks in this application.

We're talking many really [high-]quality trials. What this means — and this is very important — is that if there was any significant advantage to wearing a mask to reduce this [infection] risk, then you would have detected that in at least one of these trials, [yet] there's no sign of it.

That to me is a firm scientific conclusion: There is no evidence that masks are of any utility either preventing the aerosol particles from coming out or from going in. You're not helping the people around you by wearing a mask, and you're not helping yourself preventing the disease by wearing a mask.

  1. Annnnnnnnnnnnnnnd kicked out of Ace Hardware on Turquoise St in San Diego by terrified sheep because I didn't have a mask. I cannot WEAR a mask because a heart condition make breathing hard enough for me.

    They didn't care. Told me to put my stuff down and leave because they wouldn't let me pay for it, anyway.

    They used to be friends. These days, anyone with a mask I consider too stupid to associate with.

    As Jeff Berwick said; 'It started a s a virus scare, then turned into an IQ test, because if you haven't figured this out by now, well......'
