Personally, I’d say that at least part of what I would categorize under ‘make sense’ is objective. Namely, that you have in your scientific proposal a mechanism of action and consequence which is logically coherent. As in, an evaluation of the abstract symbolic logic of the proposal. Meeting that should be a sort of ‘minimum bar’ for considering a scientific proposal as worth discussing.
However, there will always be complications in the world which can’t be simplified down to logical assertions, so that’s only the start of the journey. However, you should feel free to reject proposals which start out making arguments that contradict themselves.
