A non-insignificant portion of the world population could be diagnosed as in a state of crisis when it comes of trusting empirical evidence and the advice of scientific institutions.
This can manifest in the form of anti-vaxers or other conspiracy theorists that base their beliefs on the core idea that certain institutions just can't be trusted and/or have a hidden harmful agenda.
This internal crisis makes extremely difficult to convince these people out of their beliefs because in theory any evidence could be falsified and facts can easily be lies.
This issue have tangible effects on the world. These issues have always been in the background but why are they more visible now?, what can we do to help this situation?, Can these people be reached in any way?, do they want to be reached?
I think that this is more of a sociological/ psychological issue and would like to know expert opinions
