Some very interesting thoughts there. I agree with the gist of your views. Have you read any books in developing these thoughts? If so, what can you recommend?
Right. One scenario could be: escaped from the lab with a technician who visited the wet market on the way home from work, sparking the first identifiable cluster.
I would say it matters for future considerations. Gain of function research is happening in many places. Leaks can happen. An unrelated virus could cause another pandemic if there are flaws that go unaddressed. The probability of a pandemic occurring doesn't decrease because this one has occurred, as they are independent events. For all we know, another pandemic could be brewing and we're so occupied with COVID19 that we're not observing it.
My wife is a researcher and says she can often guess who the authors are when she performs reviews because it's her ___domain and their references and context tend to give it away. But it's still a guess because the review process is blind. I'm pretty sure it's just the journal's editorial staff that can see who's who. It's not perfect, but it's not as blatantly biased by 'brand name' stature the way you suggest.
"Everyone" is a strong word. I'd wager you could find impressive achievements by quite a few business people with Imposter Syndrome. Believing you can succeed isn't necessary, or Imposter Syndrome wouldn't be a thing.
I've been thinking about this issue of unknown, unacknowledged, or perhaps subconscious religion a lot lately. I grew up religious but am now an atheist, and though I haven't sought to replace it component-wise, I've been observing de facto beliefs in myself and others that wouldn't normally be recognized as such because they aren't packaged as a lot. What makes me note similarities between acknowledged religious beliefs and unacknowledged ones is their function. If you look at the desired effects, they have the same aim: guidance in making decisions, association with a group sharing a particular view, value judgments both aesthetic and moral. The religions we created are a reflection of our psychology and physiology, and often the tensions between those two. It seems to me at least that a name brand religion often fills a life module that's required for a human to operate. The fact that it might be unlabeled might make it more difficult to identify, but it doesn't nullify its existence.
