Bias in Media
Bias in the media has been a problem for as long as I can remember. Students now have access to unlimited “news” stories claiming to not be biased, but that are at best telling a half truth.
All educators can agree students need to be equipped to recognize the bias, but the question is always how do we get started. I have found a few AI tools that identify media bias, but more importantly explain how that bias was calculated by the AI.
Media Bias Detector
Media Bias Detector was created by the University of Pennsylvania’s Computational Social Science Lab in 2024. It allows you to search and compare news articles to check first for coverage. Some stories aren’t reported by every paper, which can be a form of bias.
To avoid politics, I took a look at celebrities. Apparently, celebrity scandals are covered more on Huffington Post (1175 articles) than on Bloomberg (7 articles). Obviously, this isn’t a serious topic where more coverage is going to sway the public’s opinion on a serious issue, but if this was a politician’s scandal that over coverage bias (Huffington Post) would make an impact.
Furthermore, Media Bias Detector allows students to see how much of the article is facts (as calculated by AI), how much of the text is quotes, and how much is opinion. This would be a great introduction to text analysis for students.
- How does AI know what is a fact?
- How much coverage is overcoverage?
- Why might some stories not be covered?
- What are limitations for AI?
- Compare your analysis with AIs
- How might this tool be improved (like looking for charged languaged)
Media Bias Factcheck
Media Bias Factcheck is another tool that can be used to check for media bias.
Why Choose Media Bias Fact Check?
This platform stands out for its user-friendly design, featuring intuitive pull-down tabs that make navigation simple. While it offers fewer visual charts for learners who prefer graphics, its structured approach and transparency make it a powerful resource for classroom use.
Check out these features on the site
- Dedicated educator tab which includes
- activities exploring media bias including worksheets
- discussion prompts
- evaluations tools
- Human-Calculated Bias Ratings to add clarity
- There is a transparency page where their methodology is spelled out
- AI can have a bias (depending on the programmed parameters). This is a great way to compare and introduce that topic.
- Encourages students to check media bias on articles
