A disposition seems like a concept which is supposed to apply to the object in itself, independent of subject.
I wouldn’t say there’s any existence of an object (as an object) independent of a subject; there’s instead just stuff that’s not differentiated from other stuff because something had to tell the difference, hence I don’t see a real difference here, although the theory of dispositions is jumbled up with lots of philosophy that supposes some kind of essentialism, so it’s reasonable that there might seem to be some difference from affordances under certain assumptions.
Even if so, I miiight contend that there’s an important distinction between (a) affordance as a concept which is itself relational, vs (b) affordance as a predicate on objects, where objects are understood to be subjective. In the guest case, it’s possible for agents to have a shared model in which an object has different affordances for different people. In the second case, if agents try to have a shared model but end up disagreeing about affordances, it’s not clear what they should do.
