There are generally four types of articles:
News or General Interest
Scholarly or peer-reviewed journal articles are written by scholars or professionals who are experts in their fields. In the sciences and social sciences, they often publish research results.
Substantive news articles are reliable sources of information on events and issues of public concern.
Popular articles reflect the tastes of the general public and are often meant as entertainment.
Sensational intend to arouse strong curiosity, interest, or reaction. They are not factually accurate.
