Hmmm please put the story you are stating.
Authors can choose to leave out parts of data. They can choose certain events and leave out others to create a bias opinion and make you think what they want you to
By doing so you'll be able to identify useful information and through out information you don't need. It's like lets say someone says something about you you know it's not true so you can just ignore it. it also helps with fiction and non fiction stories. :)
Hope this helps.
