Fictional precedent

There is a form of law that I believe is called 'case law' where previous cases, judgements and rulings are taken into account to set a precedent.

I think we all follow a similar procedure when faced with the events of daily life, in that we search our own memories for how others have reacted / responded to related events we are experiencing.  Most of these memories however are taken from fictional examples we have seen on TV or the movies or heard about through the radio or conversation or stories / articles we have read in books, magazines and newspapers etc.

Thus we act as actors have acted(!) or as characters have acted in some drama.

Fictional precedent.

If someone controls the media industry and can promote certain authors to provide the authorised stories, then you have power and control over how people will react to upcoming events because you will have pre-programmed them through their fictional precedents.
