Not trusting the government and/or mainstream media is an understandable point of view tbh.
Or even not trusting just one half of the MSM.
The problem is, everyday science and technology has far outstripped the the average persons capacity to understand it.
Look at the origins of Covid. Someone mentioned upthread the genomic sequence is compatible with natural origin. I have no way to assess the truth of that. There are some experts who point to other markers which indicate lab processes which include "breeding" some characteristic of a pathogen to be more dominant in order to invent strong defences against. As you can tell from my cack handed attempt at an explanation, I have no ability to assess that claim either.
All I can do is pick an expert to trust.
If I already am sceptical of the govt and the MSM, I know a little about how the Chinese govt operates towards their own people never mind any others, and imagining how loathe different Govts would be to pick an open fight with them, I might be swayed towards the second experts.
That may be wrong, it even may be conspiratorial, but it's not irrational. It's an outcome of normal scepticism, and perfectly acceptable levels, though low, of the complex areas of virology and geopolitics.
If I was chatting to my friends in the pub about my interest in this, some of them would laugh in my face, or maybe someone else I respect would say No, because x. Maybe someone would agree too, if course.
But theres no pub so I Google it instead. Nobody I respect is laughing in my face. The algorithm kicks in. It's all the agreeers or else flame wars by internet lunatics which are easier to write off.
So now, here I am in a rabbit hole where all the experts are saying x and sounding authoritative about it.
What can you do about that?
You cant, or at least you shouldn't, stop people for expressing their pov's.
Trouble is, you can't really rely on he market place of ideas either, in areas like this anyway, where you need a high degree of expertise to even understand the arguments, never mind pick them apart.
Maybe the only thing you can do is formulate strong institutions which people trust and respect. But, in this case, theres a strong incentive to downplay Lab Origin theories. It actually would be in the common good to try to avoid racism against Chinese people and avoid inflaming diplomatic tensions with the Chinese state. So do you make institutions trustworthy even if the truth would cause harm?
