The reality is you can find a study to say whatever you want. Just look at global warming, I can find studies that say the end is near or studies that say its a hoax... Same thing applies here only the media has decided that they don't want to report anything except the doom and gloom sky is falling stuff. The result right now is hysterical panic, why else would people be fighting over toilet tissue. The next stage of this will be acceptance of the danger but when the danger never manifests as the people are led to believe it will they will likely start ignoring the media.. it will be like the boy who cried wolf.
This is happening now, but the issues, and justifications given, were very different.
I was an adult during the oil crisis - we were told that we had to conserve energy, buy smaller and more full efficient cars, and odd/even gasoline days and waiting in line would be the new normal - because we were running out of oil and better to suffer a bit now rather than our grandchildren living in a cold, dark world. I don't think I was the only one who "bought" the we're running out of oil scenario and then felt like a fool when I discovered it was just OPEC trying to keep the prices high.
I understand that this is very different, and will have more serious consequences if people who disregard guidelines are wrong, but we've been fooled before. I have no problem with social distancing - although I wish they would call it physical distancing. Leaving your home to take a walk in the forest is very different than going to a crowded bar. But lack of societal common sense makes a one size fits all directive necessary.
I personally am taking precautions very seriously, and am not dismissing this as nothing. I'm just trying to explain why some people who should be the most concerned about this are being so nonchalant.
As someone said, when people are in the background trying to avert disaster, and they succeed, the general population has no way of really knowing. It wasn't until I was an adult that I fully realized how much danger we were in during the Cuban Missile Crisis.
