Assumption 3.A listener is said to haveminimally consistent beliefsif each proposition X has a negation X*, and P(X)+P(X*)≤1.
One thing that’s interesting to me is that this is assumption is frequently not satisfied in real life due to underspecification, e.g. P(I’m happy) + P(I’m not happy) ≥ 1 because “happy” may be underspecified. I can’t think of a really strong minimal example, but I feel like this pops up a lot of discussions on complex issues where a dialectic develops because neither thesis nor antithesis capture everything and so both are underspecified in ways that make their naive union exceed the available probability mass.
