Resources can be biased on a wide spectrum of areas, given that it refers to prejudice in favour of/ against one thing, person or group. Bias is not always explicit and easy to identify.
To check for biased information, educators should start by verifying if the author is not identified, lacks expertise, or does not produce information on the topic consistently. Besides resources should be analysed to verify, for instance, if they:
- are deeply one-sided;
- rely on uncorroborated or unproven premises;
- are highly selective and only present facts that allow for a certain outcome;
- are mainly based on the author’s opinion rather than on facts;
- produced for entertainment;
- influence the audience to purchase of something.
