You haven't read my bloody post. You've just cherry picked a line from it.

I'm saying that it will be scripted. Not that everybody is pretending and rehearsing lines for a made up character, but that there are elements which are scripted.
It's ridiculous to believe that shows like this aren't scripted.
They have to be in order to get some sort of coherent narrative flow. For it to have a narrative structure it has to be scripted, otherwise it would probably be an unwatchable incoherent mess which no one watches.
As soon as editors and writers who plan a sequence of events get involved, subjective bias is naturally present. It can't not be. The very nature of editing it means reality is changed. That's what editing is for, to change reality into a form intended for consumption by a particular type of audience. The creative process has to introduce subjective bias when choices for what to put into the programme are made. There's no way that these programmes somehow cobble themselves together by some sort of objective process, and that everybody involved believes that they must be neutral so try to mimic the perspective of an unfeeling robot.
Many of these shows even make it easy for you by having the title 'script editor' in the credits.
The show even has its own archetypes, just like much written fiction does, and the candidates are molded to fit into those archetypal roles as much as possible.
Of course it's scripted. The question is to what extent it is scripted, and what is the motivation and purpose behind most of the narrative choices which are made.
