In FBT the provider takes an agnostic view of the cause of the illness.
Instead of identifying these various factors, energy is directed at what needs to be done to help the adolescent move forward towards recovery ASAP. Where there's blame, inevitably there's shame, inaction, or worse yet, avoidance. So no blaming the adolescent or the parents. Maintaining an agnostic view means making no assumptions about the potential cause of the illness. Especially if it distracts from the task at hand, re-nourishment.
I think of it like a sinking ship. We would waste precious time deliberating about why it is sinking or who is to blame. The more immediate task at hand is get everyone to safety!
