I did some digging this weekend and while I found my notes I did not save a link to the study. It was at time that when I was researching all the different ideas out there and it became fairly obvious that the science was being ignored on both sides, for an emotional decision making process. I am fairly positive I could find it after a couple of hours of looking but you can either take my word or not. Either way it matters not to me.kalm wrote: ↑Thu Feb 18, 2021 9:07 amWhy do they lose efficacy after being worn an hour? I’d like to see the studies.Winterborn wrote: ↑Thu Feb 18, 2021 9:02 am
Will quibble a bit on the "conservatives to do the opposite of the liberals" cause as it was probably 50/50 with just doing the opposite of liberals and the rest asking relevant questions on how the responses were chosen and the principles behind it.
For every study you can provide for it, I can find a pre-covid study that states that it causes no harm to wear them, but in the real world they are barely statistically effective due to peoples usage practices. We are not talking a brand new sterilized mask (N95 or other) that is changed every usage but ones that people continually wear. I am not arguing that they do not serve a psychological effect and initial medical effect, just that unless certain preconditions are met (proper handling, sterility, etc.) stating that a study for a new clean mask and applying that to what happens outside of lab is disingenuous. The few long term usage testing I have seen is that after less than 1 hour of the same mask one is down to a statistically insignificant filtering capability (less than a percent).
Now trying to explain the math behind the studies and how they were conducted to the general public would probably go over the heads of about 80+% of the population so I understand that one has to dumb it down it the simplest common denominator and that is the message we are currently seeing now. That masks need to be worn and that they filter all the time. It is part psychological and part science based and fits peoples understand level.
Also before you ask, I don't hate anybody. I am just indifferent and my decision making process is as cold as the land I live on.
