A text's narrativity is the result of its narrative indeterminacies. It must possess neither too much detail (being too writerly a text), which will bore and/or alienate the reader, nor too little detail (being too readerly a text), which will require that the reader "invent" his/her own narrative in an effort at coherence. Robert Scholes defines narrativity as "the process by which a perceiver actively constructs a story from the fictional data provided by the narrative medium."
