Ethical Journalistic Standards
All statistics, quotes, and statements should be factual. In order to ensure this, one must corroborate their claims by "fact-checking," or referencing a variety of dependable sources.
Even in opinion pieces, claims should be informed by facts and without an agenda of harm toward a specific person, group, or organization. Even in pieces that include negative opinions, one must consult their own bias and be critical in writing their thoughts.
Journalists should write on behalf of their own thoughts and with the intention of providing factual, useful information -- not on the behalf of hidden intentions of others, including political, social, or monetary.
