Does it ? The article seems to be mostly conjecture or studies on properly worn N95 masks (whose efficacy is not in question here).
> Osterholm, in Minnesota,director of the Center for Infectious Disease Research and Policy at the University of Minnesota, wears a mask. Yet he laments the “lack of scientific rigour” that has so far been brought to the topic. “We criticize people all the time in the science world for making statements without any data,” he says. “We’re doing a lot of the same thing here.”
This is literally how the article ends. It ends with a general acknowledgement of lack of understanding on the topic. That masks make intuitive sense, but the quality of research wrt. to it is pretty shabby.
It doesn't help that the likelihood of getting covid in outdoor settings is significantly lower than those indoors. Unfortunately, the masks almost immediately come off the second we are in this low ventilation + easily aerosolize-able environment. Mandates that are unenforceable under the constitutional structure of your nation are pointless grandstanding. (I generally question the holiness of constitutions too, but that's a whole another discussion)
Additionally no one enforces them to be worn correctly and people abandon social distancing the second their wear a mask. So they become generic tools to target and slander people rather than offer any real protection. Reminds me of post-9/11 safety measures that were intrusive enough that they could always find a bullshit reason for stop a brown person at the security checkpoint. It became an excuse for targeting ones you already had in mind, rather than ensure any real security.
I would have actually supported mandates for N95 masks and support a requirement for vaccine/anti-body mandate. (As far as we know, getting covid gives a strong enough immunity) Both would be just as draconian as the other recommendations, but, neither are useful tools for polarization, so both sides of the establishment conveniently ignore it.
