it's tempting to throw out simplistic solutions like "let's skepticism!" but almost impossible to actually change people en masse like that. which then points to your second course of action, changing processes (via the systems that implement them), and that's something i truly believe in, but still find frustratingly slow.
[0]: plus the expert fallacy, which i mentioned before. i was just having this conversation last night about doctors, who know next to nothing in comparison to how complex biology is, but we still as a society feel compelled to venerate (and remunerate) doctors irrationally because they hold people's lives in their hands (understandably). but that outsized veneration (and remuneration) often leads to egos that can't admit ignorance or doubt and that leads to millions of unnecessary deaths and countless people with worse health outcomes. and that's not a condemnation of doctors, but a realistic understanding of where our collective knowledge lies relative to the long arc of evolution, but the societal distortion persists nonetheless.
