The process of evaluating a source includes examining the source itself and examining other sources by:
- Checking for previous work. Has someone already fact-checked this source?
- Finding the original source. Who originally published the information and why?
- Reading laterally. What do other people say about this publication and author?
- Circling back. How can you revise your original search to yield better results?
- Checking your own emotions. Is your own bias affecting your evaluation?1
