Bias through selection and omission – What is the article about? What is it NOT about? Did it leave anything out on purpose?
Bias through placement – Where is this article focusing on? A certain area? A certain population? Is this skewed in any way to not represent the whole?
Bias of word and tone – Are words charged emotionally? Are they evoking feelings in the reader, or are they more based on facts? Look at tone.
Bias by headline – Is there emotion evoked in the title?
Look at word choice.
Bias by photos, captions, and camera angles – What do the pictures say about the story? Are they representative of the whole or just a part of the story?
Bias through use of names and titles – What names or terms are in the article? Are they objective or somehow biased when referring to people or organizations, etc.?
Bias through statistics and crowd counts – What data is there? Is it representative of the event as a whole?
Bias by source control – Who or what are the sources of the article? Are they reliable?
