Not to get this thread too side tracked, but alot of the disbelief by some is due to their observations previously of both the "experts" and MSM being wrong. While others will believe these sources until they are proven wrong. Those that do not believe in the seriousness of Covid are those that have become extremely cynical with both sources of information.
I fall in the cynical category to a degree, but I do not immediately dismiss what they have stated. I am a scientist but have a history degree that has really helped me analyze and evaluate sources of information on Covid and knew back in February how serious this could become. The last ten years is just littered with MSM looking for click bait rather than informative reporting. But I was raised on fool me once, shame on you, fool me twice and shame on me for allowing it a second time. I think many were brought up with the same belief system, they feel foolish following a source they cannot trust. This is why the CDC and somewhat the WHO public positions that changed (especially related to mask wearing) have such resistance. And thus the lack of cooperation with proper advice.
Unfortunately this will be a long winter, everyone stay safe.
