I don't want to get into the pro mark vs against mask debate. but i want to enter in the defense of properly executed scientific tests.
Remember that correlation is not causation. That is one reason why it is important to have a randomly selected set of cases in a trial. Without randomly selected sets other factors might be at play, like in your Kansas example.
if you are looking for scientific proof that masks help, you need to abide by high standards. With that said, often a proof is not necessary, the basic sense that it helps can be sufficient. and in a situation of danger, like a pandemic, just the fact that it probably helps should be alredy enough.
Many scientific facts that we hold for truth are not proven, they are just not been proven wrong.
Also, it would be good to remember that exchange of ideas and debate is the foundation to science, what is held as truth today might be proven wrong tomorrow. I'm not saying to listen to crazy people making crazy suggestions about chloroquine or whatever that was, i'm just saying that those who profess to follow science should not forget that science evolves constantly. Science and dogma are opposite, let's not try to make them one.
it has already been decided that "per capita" in the pollution department doesn't matter.
Citation Needed. BTW, India, which has roughly the same population as China, produces about 1/4 of China's pollution, kudos to India.
