I understand what you're saying but skepticism is also a tool for manipulation. We now have a significant number of people who are rejecting the Covid vaccine because they're "skeptical" or "waiting for the evidence" or, the worst, they've "done their own research". Hint: some random guy talking about this in his basement and putting the video up on YouTube is not "research". The fact of the matter is that we simply can't be skeptical about everything and research everything. It's physically impossible. It's why we delegate authority to people and institutions who do actual research and have credibility. It's why I listen to the CDC about diseases and CERN when it comes to physics. "Skepticism" these days is often a euphemism for confirmation bias.
