Anyone can publish a paper nowadays, technology has made that very easy. But trust is still something that needs to be earned, and that takes time. It makes sense to have trustworthy institutions, I don’t think it’s something we can easily replace with technology.
Humans will always accept some axiom as truth without really verifying it. It's impossible to do so. Can any single person truly know how everything in their computer works? Or how the machines that made the semiconducter work? Nope. All we can do is try to determine the truth by proxy, which means the truth can and will always be manipulated.
I'd argue it's deeply unhealthy to have any trust at all in governments that have shown themselves to be authoritarian or oppressive.
The question is which institutions and people do we place trust in? When they contradict each other whom do you believe? Should we believe them sometimes but not others?
That's where people get irrational and antivaxxers are just one example of that.
Yes, it's blindingly self evident that you cant run your own vaccine trials.
Is it really so irrational? How many people have the technical know-how and access to equipment to personally verify that COVID vaccines are safe for human consumption? (Can you even verify that on your short of running mass human trials?) And yet, by and large, most of us are not conspiracy theorists who wonder if the vaccine will secretly kill us or render us infertile.
There are often good reasons to trust the official narrative. There are often good reasons to distrust it too, but placing trust in people and institutions is often not so irrational.
