Law Of conservation of difficulty

Began Reading "The Human Touch" by Michael Frayn. it's a great book

however he quotes the law of conservation of difficulty

"Obscurantism in an academic subject expands to fill the vacuum of its intrinsic simplicity".

I don't understand what this law means. can someone put it in simpler terms for me and explain it.

Thanks

Ask Ophiolite, he kinda talks like that.

The defintation of - Obscurantism - ''A deliberate act intended to make something obscure''

My interpretation of the following is as follows that..

"Obscurantism in an academic subject expands to fill the vacuum of its intrinsic simplicity"

Things are often talked about between people as one thing when in reality people have different interpretations of that very thing. Somethings are simple and we can talk about these is seemingly absolute truth - such as - a great chronic pain in the arse. We can all say quite confidentaly to each other that this is dam painfull and we are in dislike about this chronic pain in the arse...

However if we are talking about time.. We all think differently of this word and therefore it is sometimes in place for a person to obscure the defination of the word to cause confusion and question within others minds - in the hope to create a blank vacuum where the people actually start to wonder ''what do i really know about this?''..

This leading maybe to a greater understanding.
