So there’s something to that, but I’m a little wary about taking that interpretation too far. Taken far enough, it implies that if group A has a sensible take on a concept, then as soon as a group B shows up that has a bad take on it, you can use it to discredit A as a motte for B. It seems bad if we can discredit any concept—including valuable ones—just by making up a bad take on it and spreading it.
But suppose that we were discussing something of which there were both sensible and crazy interpretations—held by different people. So:
group A consistently makes and defends sensible claim A1
group B consistently makes and defends crazy claim B1
and maybe even:
group C consistently makes crazy claim B1, but when challenged on it, consistently retreats to defending A1
Now we are at the worst possible situation. Suppose that I belong to group A, and want to defend my group against an accusation. I say that no, we don’t believe in crazy claim B1, we actually consistently maintain claim A1, and always have. I have links to back this up.
The other person says that this is just a motte and bailey, digging up links of group C using A1 as a motte—and is entirely correct.
In the comments of that post, the most upvoted comment was one suggesting that you can distinguish a motte and bailey by looking at whether one of the groups actively disclaims the other:
If different people in the group make sensible and crazy interpretations, and you’re arguing with someone who claims to be making only the sensible interpretation, I’d expect that that person would at least be willing to
1) admit that other members of the group are saying things that are crazy. They don’t have to preemptively say it ahead of time, but they could at least say it when they are challenged on it.
2) treat known crazy-talking people as crazy-talking people, rather than glossing over their craziness in the interests of group solidarity.
I’m also very suspicious when the person with the reasonable interpretation benefits too much from the existence of (and the failure to challenge) the person with the crazy interpretation. His refusal to condemn the other guy then looks suspicious. The term for this is “good cop, bad cop”, and the fact that we have already have a term for it should hint that it actually happens.
So if we think that a party not explicitly disclaiming a bad interpretation makes it more of a motte and bailey, then a situation where a party does explicitly disclaim it should make it less.
Also, with regard to the bit you quoted… I’m not sure if you could characterize it as “true believers advancing the Bailey under the cover provided by others who defend the Motte” if the ones who defend the Bailey and the ones who defend the Motte have positions that are the exact opposites of each other?
The original example of motte and bailey, as explained by Scott Alexander, was:
The original Shackel paper is intended as a critique of post-modernism. Post-modernists sometimes say things like “reality is socially constructed”, and there’s an uncontroversially correct meaning there. We don’t experience the world directly, but through the categories and prejudices implicit to our society; for example, I might view a certain shade of bluish-green as blue, and someone raised in a different culture might view it as green. Okay.
Then post-modernists go on to say that if someone in a different culture thinks that the sun is light glinting off the horns of the Sky Ox, that’s just as real as our own culture’s theory that the sun is a mass of incandescent gas. If you challenge them, they’ll say that you’re denying reality is socially constructed, which means you’re clearly very naive and think you have perfect objectivity and the senses perceive reality directly.
Here what’s going is that the motte and bailey are basically weak and strong versions of the same claim, so people believing in the strong version can take support from arguments in defense of the weak claim. But if some people say that “yes I think people who don’t use NVC are being violent” and others say that “no that just happens to be an unfortunate established term, what kind of language you use has no bearing on whether you’re violent or not”… then that doesn’t seem like the strong and weak versions of the same claim? That’d be like saying that creationists and evolutionary biologists together form a motte and bailey, because both use the term “evolution” but assign different meanings to it (some saying that it’s true, some saying that it’s false).
So there’s something to that, but I’m a little wary about taking that interpretation too far.
