@dougmerritt@mathstodon.xyz You said: "But as practitioners, we must assume at least for the moment a number of pragmatic concerns, such as that reality is real, in some sense." But don't interpretations like QBism sort of deny exactly that? https://en.wikipedia.org/wiki/QBism @davidsuculum@mathstodon.xyz

@internic@mathstodon.xyz Sorry if I'm being confusing about what position I'm taking, but it's because at the moment, I'm not taking a position. I'm just saying that we should all be careful to distinguish the different kinds of probabilities and to consciously choose one, rather than acting like they're all the same. I then went on to suggest that, when our goal is to be pragmatic practitioners (as opposed to when we're in the mood to discuss metaphysics for its own sake), then we should pick tactics consistent with that, such as assuming that reality is real, and the like -- there's a time and a place for things, that's all. That QBism page is interesting; I should reread it more carefully. @davidsuculum@mathstodon.xyz
