How to Evaluate Research Sources (CARS model)

Is your source credible, accurate, reasonable, and supported?

The CARS Checklist

1. Credibility

your source should be authoritative (you should see evidence that allows you to trust it)

check the author’s credentials

there should be evidence of quality control (e.g. peer review)

2. Accuracy

your source needs to be up to date

facts should be complete, not partial

your source should provide the whole picture, not an incomplete picture of the real situation

3. Reasonableness

your source needs to show evidence that it is fair, objective, and does not have a conflict of interest

there should be no logical fallacies, biased tone, or obvious slant

4. Support

your source needs to be supported by other sources

the author needs to be clear and upfront about where information came from
