Agreed that hidden-motte-and-baileys are a thing. They may also be caused by pressure not to express the actual belief (in which case, idk if I’d call it a fallacy / mistake of reasoning).
I’m not seeing how they synergise with the ‘gish fallacy’ though.
mathematicians know that a single flaw can destroy proofs of any length
Yes, but the analogy would be having multiple disjunctive proof-attempts which lead to the same result, which you can actually do validly (including with non-math beliefs). (Of course the case you describe is not a valid case of this)
TBH, a central object of interest to me is people using Dark Epistemics. People with a bad case of DE typically have “gishiness” as a central characteristic, and use all kinds of fallacies of which motte-and-bailey (hidden or not) is just one. I describe them together just because I haven’t seen LW articles on them before. If I were specifically naming major DE syndromes, I might propose the “backstop of conspiracy” (a sense that whatever the evidence at hand doesn’t explain is probably still explained by some kind of conspiracy) and projection (a tendency to loudly complain that one’s political enemies have whatever negative characteristics you yourself, or your political heroes, are currently exhibiting). Such things seem very effective at protecting the person’s beliefs from challenge. I think there’s also a social element (“my friends all believe the same thing”) but this is kept well-hidden. EDIT: other telltale signs include refusing to acknowledge that one got anything wrong or made any mistake, no matter how small; refusing to acknowledge that the ‘opponent’ is right about anything, no matter how minor; an allergy to detail (refusing to look at the details of any subtopic); and shifting the playfield repeatedly (changing the topic when one appears to be losing the argument).
