I would say the kalman filter is quite appropriate where the state is our model of the world, the 'page flip' as a state update based on observation. Also the same as a Bayesian model update:
with a kalman filter the model always stays the same and is used to pick which sensor is reporting most accurately. changing the model would change everything, maybe that's why changing your worldview has such an impact on the way you "see" things.
> state = kalman(state, observation)
