Two things in reply.
One, you present this as if it's a priori logic, but in fact it's an empirical conjecture (about possible psychological states) and you're making it on what seems to be a pretty thin evidence base.
Two, I don't know anyone who plays FitD or PbtA games in what you call "writes' room" mode, and so I doubt that
@niklinna does either. That's not how those games are supposed to be played according to their designers, and everything I've seen @nikilinna post makes me think that the designer's instructions are being followed.
