None of this is new, you’ve seen it all, but I hope by showing you where it comes from that you’ll be better equipped to handle anti-mask bullshit from bloviaters.
Masks make a difference. They do help. How do we know that? I’ll show you. Usual mea culpa: I’m an amateur who believes the experts – and only the experts, based on real research – not an expert myself.
I’ve gathered some of what experts have done – and then what they say. After that, we’ll check the anti-mask “evidence” spread on social media by non-experts who often say what HUGE experts they are, then tell you masks are bad without doing any experiments (cos designing, then doing, good experiments is not easy and it takes time) and without any valid evidence.
First, why even talk about masks? Because we breathe. We all know people who emit spittle as they talk, and we dodge them and stand back when they get excited! But we don’t all realise that we ALL emit droplets when we speak. Here are two graphs in the same block of someone saying the words “stay healthy” while wearing a mask and while not wearing a mask. The person’s emissions were video’d under special conditions (check the link):
Here’s a snapshot of one frame in the video, which corresponds to the top bigger red arrow in Panel A – the highest number of speech droplets visualized in an individual frame of the video recording.
OK, so we have evidence that we spray. Of course, your Granma knew we spray germs when she told you to ‘catch your cough’ and when she avoided you when you had a cold (which is also a corona virus).
Next we found out that COVID-19 can be found on way smaller droplets than these – called ‘the aerosol effect.’ Now you need to not just avoid being coughed on or ‘spoken on,’ you need to be wary of the air where people have been, as aerosol particles linger WAY longer and travel WAY further than the bigger droplets which led to the 2m ‘social distance’ guideline (which politicians and businessmen soon reduced to 1,5m, down to 1m, down to ‘full taxis’ – side-by-side. These reductions were NOT done for our safety, BTW!).
Next, we (“we” – scientists on behalf of “us” – humans who know the scientific method is the best way to investigate things) looked at old epidemics and noticed there was less spread in places where people are used to wearing masks. In April already, this effect was noticed in the current pandemic too.
Next, scientists looked at 172 studies on corona-type viruses. After very careful analysis they gave a sober, cautiously-worded statement (this is a tiny excerpt – click the link to read the full study): ‘We found evidence of moderate certainty that current policies of at least 1 m physical distancing are probably associated with a large reduction in infection, and that distances of 2 m might be more effective, as implemented in some countries. We also provide estimates for 3 m. The main benefit of physical distancing measures is to prevent onward transmission and, thereby, reduce the adverse outcomes of SARS-CoV-2 infection. Hence, the results of our current review support the implementation of a policy of physical distancing of at least 1 m and, if feasible, 2 m or more. Our findings also provide robust estimates to inform models and contact tracing used to plan and strategise for pandemic response efforts at multiple levels.The use of face masks was protective for both health-care workers and people in the community exposed to infection, with both the frequentist and Bayesian analyses lending support to face mask use irrespective of setting.’
The most recent study I found was in Denmark where masks were not compulsory and most people did not wear them. A trial showed that people who did wear them in a randomised trial did get some benefit, even when all others around them were not wearing masks.
SO: You’ve always known this, but which is the best mask to use? Its not important. Comfort is probably the most important consideration, as wearing it comfortably and consistently is key. Having the ‘world’s best mask’ around your chin helps a rich, approximate, earth-shattering, statistical fokol. That’s zero. May as well strap it around your wrist fgdsake.
If you want a suggestion, surgical masks are generally more protective than cloth masks, and some people find them lighter and more comfortable to wear. The bottom line is that any mask that covers the nose and mouth will be of benefit. The concept is risk reduction, not absolute prevention. Don’t not wear a mask ‘because it’s not 100 percent effective.’ That’s just silly. Nobody thinks burglar guards are 100% effective, they install them to substantially reduce their risk.
Remember ‘All I ever needed to know I learned in kindergarten?’ Wash your hands often and well; Wear your mask; Keep more distance than you think (3m is better than 2m is better than 1m is MUCH better than french kissing); Avoid closed spaces (any indoors if you can help it; at least reduce that ‘essential’ indoor time); Avoid people (yeah, yeah, as far as you can – and that’s usually more than you do; also reduce your time spent with them); Get your groceries delivered (Checkers charges R35 to deliver up to 30 items within one hour – it costs you more to drive there and back and you’re rating your time at R0 – How much time have you got left on earth? Correct, you don’t know. But you do know that it’s precious).
What about “scientific evidence that PROVES masks are bad for you”?? Search for it. It will take you to wacko sites that tell blatant lies absolutely routinely. Always check the sites on wikipedia; and check their claims on snopes.com, and other fact-checking sites. Here are ten of the best fact-checking sites. Use them!
The Federalist is one bullshit site. They also publish false information and pseudoscience that is contrary to the recommendations of public health experts and authorities; and fake news about election results. Trump fans.
Typical of these sites’ disinformation was taking the Denmark study I mention and saying “A study in Denmark proved that masks are useless for COVID-19,” instead of the truth: The study found that face masks did not have a large protective effect for wearers — but did provide some protection to wearers, and did also provide benefits to other people. Note the difference in language: The DEFINITE conclusions by bullshitters; vs the CAUTIOUS conclusions that real scientists take, knowing things may change.
Another instance was taking one case of a driver who crashed his SUV into a pole in new Jersey on April 23. He blamed his collision on his mask. He told police he passed out because he’d been wearing an N95 mask for too long. Initially, the investigating officers believed him, writing in a Facebook post that he was the only person in the car and passed out due to “insufficient oxygen intake/excessive carbon dioxide intake.” The driver’s bulldust went viral! The police department later updated their post, stating that they didn’t know “with 100% certainty” that “excessive wearing” of an N95 mask was a contributing factor to the accident. They added that “it is certainly possible that some other medical reason could’ve contributed to the driver passing out.” But bullshit websites crowed “masks are bad for you, you get too much carbon dioxide!’ – and people who should know better forwarded and forwarded without checking (please don’t do that). A quick check can show you: actually, you don’t.
Another website The Gateway Pundit “is known for publishing falsehoods, hoaxes, and conspiracy theories.” So when they tell you ‘All the experts are wrong, we have scientific proof masks are bad for you!’, check their research, then check some real research – and then dismiss them with the contempt they deserve.
Go and find a fact-checking site now. A slightly different ‘ten best’ are suggested here.
There’s also AfricaCheck.org for checking bullshit in Africa – we sure need them, so I sent them a donation. Go and see how they caught Herman Mashaba bullshitting.
Oh, and please note I use the term BULLSHIT very deliberately. It’s a real thing:
In his essay On Bullshit (originally written in 1986, and published as a monograph in 2005), philosopher Harry Frankfurt of Princeton University characterizes bullshit as a form of falsehood distinct from lying. The liar, Frankfurt holds, knows and cares about the truth, but deliberately sets out to mislead instead of telling the truth. The “bullshitter”, on the other hand, does not care about the truth and is only seeking to impress.
Quote: “It is impossible for someone to lie unless he thinks he knows the truth. Producing bullshit requires no such conviction. A person who lies is thereby responding to the truth, and he is to that extent respectful of it. When an honest man speaks, he says only what he believes to be true; and for the liar, it is correspondingly indispensable that he considers his statements to be false. For the bullshitter, however, all these bets are off: he is neither on the side of the true nor on the side of the false. His eye is not on the facts at all, as the eyes of the honest man and of the liar are, except insofar as they may be pertinent to his interest in getting away with what he says. He does not care whether the things he says describe reality correctly. He just picks them out, or makes them up, to suit his purpose.”
Bullshitters can exhaust you. As Alberto Brandolini’s Bullshit Asymmetry Principle states, “The amount of energy needed to refute bullshit is an order of magnitude bigger than to produce it.” Dr. Brené Brown, research professor at the University of Houston, Graduate College of Social Work seems like a very good and kind and decent person. Because she suggests we use generosity, empathy, and curiosity when speaking truth to bullshit (e.g. “Where did you read this? or Where did you hear this?”) can go a long way in our efforts to question what we’re hearing and introduce fact.
