Bias
Middle School
Definition
A tendency to favour one side, person, or viewpoint, often shown through word choice or by leaving out information. Loaded or emotional language can signal bias. Recognizing bias helps readers evaluate how fair and reliable a text is.
Worked examples
"The reckless protesters disrupted traffic again yesterday."
"Reckless" and "disrupted" are loaded words that show bias against the protesters.
"Senator Kim has championed tax reform, while her opponent has flip-flopped on the issue."
"Championed" is positive, "flip-flopped" is negative—word choice reveals the writer's bias.
Common mistakes
- Only opinion pieces contain bias → News articles can also show bias through word choice and what facts are included or left out Bias can appear in any text type, even those that claim to be objective.
- If a text includes both sides, it has no bias → A text can present both sides but still show bias through word choice, emphasis, or unequal treatment How information is presented matters as much as what is presented.
- Bias always means the information is false → Bias affects how facts are framed; the facts themselves may be accurate but presented unfairly A biased text can contain true information but still favor one viewpoint over another.
Where you'll use it next
You'll apply bias detection when analyzing news articles, speeches, advertisements, and historical documents in social studies, and when crafting persuasive essays where you must acknowledge and avoid unfair bias.
