I think a more basic problem is people don't even know how to formulate meaningful probability hypothetical/counterfactuals to begin with (let alone update them). For Covid stuff pretty much all an individual should care about is:
P(Bad Stuff | I take action A) > P(Bad Stuff | I take action B)
So you take action B in this scenario (simplifying to ignore costs, many of these decisions are costless). We get a bunch of meaningless drivel in the news though that doesn't help anyone make any meaningful probability estimates to help them make decisions. I think the Rogan/Gupta interview is a good example. We get various non-sense comparisons such as:
P(Bad Stuff | Covid, Person 5, No Vaccine) < P(Bad Stuff | Covid, Person 50, Vaccine)
[Rogan to Gupta why is it OK for 50 year old to feel safe and not a young kid without a vaccine? Irrelevant counter-factual unless someone invents a reverse aging treatment.]
P(Heart Inflammation | Covid Vaccine, Young Male) > P(Death | Covid, Young Male)
[Rogan saying side effects for young people outweigh benefits. This is true but death is quite a bit worse than the side effects, and this does not consider other Bad Stuff from Covid like long haulers.]
Knowing Bayes Theorem doesn't help someone figure out the right probability statement they should be interested in to begin with.
