I think if the pandemic has taught us anything it's that we need to be flexible in our opinions and approach as new information comes to light. Anyone who hasn't had to change their opinion on a whole bunch of issues to do with the virus over the last year and a half is either an unfeasibly lucky guesser or is doing something wrong.
Also, we've got to stop assuming a conspiracy and bad intent all the time. Whenever underlying information changes, and the experts must therefore change their guidance, people come out of the woodwork to declare "See! Mr. Expert changed his mind! He was obviously lying before. Is he lying now? What can we believe with all these liars lying?"
