> The Kamitakamori tools? Piltdown fossils? The pattern roughly seems to be "if you have physical artifacts that support a theory / fit a pattern they will be accepted (even if bogus)
Two examples from over a century is not evidence of unreliability.
> if you have a theory that explains facts (e.g. drilled holes) but no physical artifacts (in this case drills) it will be rejected".
Evidence is a requirement in all scholarship; the rest is speculation - which can be useful as a direction for searching for evidence, but is not sufficient to be accepted in any field. What field accepts claims without evidence?
They didn't say things should be accepted without evidence. That's a laughably bad-faith reading. They proposed a different standard of evidence that they think is less infeasibly high while still not accepting nonsense. I don't totally agree but it's a reasonable direction to argue.
As for the examples, when they start with "swings over the years" they're clearly taking a long-term perspective, and not trying to claim that modern archaeology will "believe anything" (especially not when their more prominent claim is that modern archaeology believes too little).
