[vjmyziel] Civilization scale experiments

A vastly advanced and perhaps heartless civilization wants to know what the effect of Policy X will be on society.  So it runs the scientific experiment, setting up Policy X and a control in separate environments, perhaps continents or planets, perhaps replicated to achieve statistical significance.  The experiment runs, perhaps taking generations, and they get their result.  Afterwards, clean up involves killing everybody.

With actors raising babies, it may be possible to set up almost any initial conditions, as babies are born with a clean slate not suspecting anything, including that they are part of a giant experiment.
