How can fake news be identified​

Explanation:

In the U.S., instances of identifiable fake news can be seen as far back as the colonial period. On Smithsonian.com, Jackie Mansky cites historian David A. Copeland’s assertion that throughout England and colonial America since the 1640s, pamphlets were distributed in an attempt to promulgate partisan opinions. According to Copeland, these pamphlets were “setting precedents for what would become common practice in eighteenth-century England and America.”

George Washington, John Adams, and other Founding Fathers were displeased by how they were portrayed in newspapers, yet they still advocated for and defended freedom of the press. James Madison in particular understood the “power that public opinion wielded,” according to Mansky. In the eighteenth century, it was more difficult to verify whether the material a newspaper printed was true, and it was nearly impossible to undo the damage to public opinion after people had been wrongly manipulated by inaccurate, incomplete, or blatantly false information.

The owners of publishing platforms are far from the only people guilty of spreading fake news to achieve their goals. As mentioned above, political leaders have long depended on newspapers, and more recently on films, television, and other media, to spread misleading, falsified, or emotionally charged propaganda for their own often-nefarious ends.
