Motte-and-Bailey effect (when instead of happening inside a person's head, it happens to a movement - when different people from the same movement occupy motte and bailey (I think that individual and group motte-and-bailey's are quite distinct))
This could just as easily be described, with the opposite connotation, as the movement containing some weakmans*, which makes me think that we need a better way of talking about this phenomenon. 'Palatability spread' or 'presentability spread'? But that isn't quite right. A hybrid term like 'mottemans' and 'baileymans' would be the worst thing ever. Perhaps we need a new metaphor, such as the movement being a large object where some parts are closer to you, and some parts are further away, and they all have some unifying qualities, and it is usually more productive to argue against the part that is closer to you rather than the part that is far away, even though focusing on the part that is far away makes it easy to other the whole edifice (weakmanning); and motte-and-baileying is ascribing to the further-away part of your own movement but pretending that you are part of the closer part.
*in the technical sense; their positions may be plenty strong but they are less palatable
Edit: Whoops no one will see this because it's in an old open thread. Oh well.
What I had in mind was a situation when "a person from outside" talks to a person who "occupies a bailey of the movement" (for the sake of simplicity let's call them "a movement", although it doesn't have to be a movement in a traditional sense). If the former notices that the position of the latter one is weakly supported, then the latter appeals not to the motte position itself, but to the existence of high status people who occupy motte position, e.g. "our movement has a lot of academic researchers on our side" o...
