This zeitgeist goes back to the creation of America: the people were mistreated by the monarchy. Distrust and accountability to the government is baked into the American constitution (that accountability has succeeded in some areas, as much as it has failed in others).

It seems that many confuse science for government, which is understandable given the very recent muzzling of science for political gain.

Fauci's facial expressions during and after the recent regime have been a pretty good litmus for me: he's a scientist that's bad a hiding his emotions. That allows me to figure out when to trust what him and his colleagues want to, or have been forced to, say.
