Reading journalism is different from reading other types of nonfiction because nonfiction tends to utilize objectivity—meaning to write without bias—to convey their main ideas and key statements. On the other hand, many pieces of journalism often includes writing opinions on real events and subjects. For example, a Wikipedia article may talk about a criminal case by stating the date of the trial, the crime committed, and the result of the verdict, while a journalist may write about how terrible the crime was, how the criminal should have been punished severely for their crimes, and call to act on just jurisdiction.
Additionally, journalism involves doing heavy amounts of investigative research, such as interviews, tape recordings, and ensuring that the story they write about and research will get heavy and widespread coverage. It is about bringing events to the public eye, and making known them by covering them deeply.
While other nonfiction pieces may simply tell about an event or subject, journalists will investigate the event, interview those involved, and make an argument for their story.
