The risk of death if you get polio is much higher than COVID, but the probability of getting COVID is much much higher than it was of getting polio. This makes the overall current risk if dying from COVID roughly 100x the overall risk of dying from polio was in 1952. I realize that, psychologically, a low-probability-high-risk event can seem scarier than a high-probability-lower-risk event, but is it really unreasonable of me to expect people to also be able to make rational assessments of overall danger? Do you really think we're complete slaves to our psychological biases?
