Surely an aware author will pitch the level of his/her writing to the average readership of the book/magazine/'paper.?
Although, without seeming to be either condescending or insulting, it's probably better to remember that well-known acronym: 'KISS.', (Keep it simple, stupid.),.
Over the years I have written instructions for the 'Black Knight.' research vehicle; the 'Yellow River.' RADAR., aboard ship, (for land-lubbers.), and so on and so forth. It has ever been a question of just how far DOWN the average reader's intelligence level should one write and I've found that 'KISS.' is as good & a simple guide as any.
If the average reader were able to say: 'Of course I knew that.' then possibly the correct level had been struck?
