All of these quoted studies and tweets are incomplete and ignore nuances and other details that impact results.
in short, its all cherry picking just the right info to back your pre-determined view point.
like in the post above...what's the quality of the mask? Was fitment advised? Or was the same masked used all year so that the elastic bands drooped so much there was a 1" gap from their face?
In attempts for civility, we should try not throw "this tweet is a fact" at people, take that.
IMO, we pay our tax money to the CDC and NIH for this exact purpose. They are the closest thing we have to a source of truth, and they have had essentially the same people in place for decades, thru multiple administrations. They are slow, extremely conservative in nature, and terrible communicators of their conclusions/recommendations at times. But they do have data that should be trusted....by far over all other sources.
