When I was doing my postdoc I worked with a really smart and clever young chemistry grad student. He was VERY smart...in chemistry. He was also a young earth creationist. He didn't know anything about geology which made that position a lot easier to hold for him.
Great intelligence in one area doesn't guarantee great intelligence in all areas.
Right, and knowledge in some areas doesn't at all equate to knowledge in every or even most areas.
My guess is that many not getting a Covid vaccine don't understand their risk of long Covid.
So, they miscalculate the risk/reward ratio.
Like me, many would not get a flu vaccine unless the risk of serious flu illness seemed serious enough to them personally.
So, for example, I've several times in life r
ushed to get a tetanus vaccine, but at this still midlife age with a strong immune system, I will probably will continue to rarely get a flu vaccine, just because I'm willing to accept the risk of flu, so long as it's a typical flu.
So, an error many are making I think is to wrongly think getting Covid isn't much of a risk for them, that's it's only akin to something like the flu, since they are under 70 or whatever.
And they probably are entirely clueless about Long Covid risk.
How many even have a reasonable idea about Long Covid risk, that it's up near the order of a 1 in 10 risk (compared to the far lower risk of death which is more close for most of us is below 1 in 1,000)?
Also, not knowing that risk, another aspect probably not widely understood is how awful it would be to have 2 or 3 or more months of life to being weak and feeling awful.
