Scholarly or Popular?

Scholarly articles are written by researchers or experts in a particular field. They use specialized vocabulary, have extensive citations, and are often peer-reviewed.
Popular magazine articles are typically written by journalists to entertain or inform a general audience,

Distinguishing between facts/information and viewpoints/opinions is a skill. Keep the following in mind:

A journalist observes, gathers, assesses and presents news and information. They are also called reporters. Journalists are trained to be fair and impartial - they keep their opinions out of the story.
A columnist or a critic works to persuade to convince you of a viewpoint based upon their expertise or experience.
