(1) producers of reality shows are being smart, not unethical, when they give their "actors” scripts to follow. (2) if producers had to follow everyone around waiting for an exciting event to occur, they would never make their deadlines to produce the episodes. (3) therefore, scripted reality shows reflect efficient planning, not sheer deceit. (4) furthermore, the scripts do not change the fact that the shows are based on the real lives of the "actors.” (5) for example, if a reality show were about an interior decorator, the producer would never give the decorator a script related to running a restaurant. (6) the producer would, of course, always create scripts that related to decorating.
