To be fair to a lot of people, the "experts" have a long list of goddamn stupid and horrific things in the past to make blind faith in them questionable at best. Most recently, COVID highlighted the elite panic where they thought that lying to people about mask's effectiveness was a good idea to try to conserve them for medical workers for earlier shortages, along with making everyone waste time with obsessive cleaning against a threat they already knew didn't exist. They decided to try to be strategic and all they did was prove that they were willing to lie and thought that they knew better than you. Despite medical ethics including what can be best summed up as "don't lie to your patients, you don't know better than them for what is best for them".
Reputation is hard to build and easy to break, and well every decade there are enough events to break it even before dealing with propagandists and lumping all experts into the same basket. The experts said there were WMDs in Iraq too. Increased transparency combined with a less than stellar history means that institutions have fully earned their cynical reception. Horrifyingly is the damage that such misconduct has wrought, as even when they are actually 100% right this time people have reasons to doubt them.
