The way dice work in pbta allows us to hand narrative agency back and forth between Players and GM, depending on how they fall.
Austin said something to that account in the recent tips and it stuck with me because agency at the table is an immensly important topic to me. (thread)

I think it is important for us to accept that rolling dice isn't just a way of creating randomness but an active abandonment of narrative agency over your character, or the world you are portraying.

This is important because it means that if a player is not willing to give up narrative agancy, we should find other ways of resolving situations, or negotiate the amount of narrative agency they are willing to give up.

We should reflect this attitude in how we teach our rules. I think rules have a responsibility to free the reader to create stories not force them into consenting to a storytelling algorithm. Our rules should contain these elements of negotiation or at speak of their nessecity.

I think this is also where i find pbta extremely powerful. In my experience consent needs clarity and pbta makes it clear that there is a back and forth trading of narrative agency. This allows players to actually embrace agency and not surrender it to the storytelling algorithm.
