Vlad,
Survivor bias is a bit of pop business oriented talk.
You have the same approach here as AB. When you’ve been caught out in a fallacious argument, you attack the fallacy itself (a sort of "fallacy
ad hom") rather than deal with the problem you’ve caused yourself. AB calls them “man-made”, you call them “pop business orientated” (whatever that means) but it’s the same “play the man, not the ball” dishonesty.
There is little of substantial support for your application of it here.
No, your “how come a community survived if their belief wasn’t true?” trope is
precisely the structure of the survivorship bias. Read the link I posted and you’ll see why.
Even a broad reading of Grimes research findings would trump your extremely broad reading of survivor bias........
Of course they wouldn’t, and I have no idea why you’re bothering with the conspiracy line as for what it’s worth that seems to be to be one of the less likely explanations. Simple error or a deliberate trick as examples wouldn’t entail a conspiracy at all. Countless communities have believed countless things that aren’t true with no conspiracy involved in the phenomenon, which should at least give you pause before making this mistake again.
