4. People reading science fiction will come to the story with certain knowledge and expectations - or lack thereof - dependent on their past experience with reading science fiction.

Readers and writers new to science fiction need to realize that there is a jargon which A) readers are expected to already know: words and concepts like "hyperspace," "psionics," "teleporation," "robotics," etc., or B) readers are willing to try to understand from context.

This can make it difficult for readers new to science fiction; it should not make it difficult for the writer.  The writer should not feel compelled to educate the reader with regard to the standard jargon of science fiction.  This is not done in any other genre, and it should not be done in science fiction.
