I think I understand your argument, but I think you misunderstood me. I agree that just looking at credentials isn't the way to go. It does create these echo chambers where only those wearing "my colors" can be correct (when perhaps people need to see and hear those without "their colors"). But my argument was never to resort to pure credentialism. Looking at someones background is an important tool in our toolbox for finding the truth. My argument wasn't that a background check should replace scientific debate.

Exactly! And to the 95+% of people who commented or clicked the opening link who do not have a background in bioengineering, how could they take a critical and informed stance to what the paper claims? The claim of the pandemic being man-made affects them, wheter they can fully understand the scientific discussion or not! I never meant to say that there is no-one on HN that cannot have the scientific discussion. I meant to say that most people simply have other skills than bioengineering in their toolbox, but they do have the ability to judge someones character if they find background information about them.

Maybe I should have put more emphasis on "generally" when I wrote it, but I hope I have clarified my point here and that you see it is very much in line with your thinking.
