Decide by consensus

A few moves call on the group as a whole to choose an outcome, like how End of Session has everyone answer the XP questions together.

This approach produces a "writer's room" effect, where the players talk about the game at a meta-level. It's a natural fit for End of Session, because the whole point of that move is to get the players to reflect on recent events. But you could certainly write a move in which the group decides between fictional outcomes by vote or by consensus. Just make sure that's something your players are into!
