What's interesting to me is where "tribes" and "logic" intersect, and that's in the scientific community...
At best, it's a "tribal" structure that adopts certain heuristics based on well-understood science, so it's supported by the logic underneath it. At worst, the "tribal" aspect overwhelms the logical, which is one thing that makes scientific revolutions difficult.
Good example with vaccines: Most vaccines are safe and effective, don't cause autism, etc. Backed up by decades of studies ever since Wakefield was debunked.
Bad example with lab leak: Our tribe doesn't want to appear to be racist or promoting anti-Asian hate, so we're going to label the lab leak idea as "conspiracy theories", beyond the pale of discussion, etc.
As always, the solution to bad science is better science, just like the solution to bad speech is better speech.
