The person being interviewed here is a FACT CHECKER.
FACT CHECKERS are employed by reputable (good) publications and news services to check that all the facts in a story are correct.
Want to become a FACT CHECKER? You need some RULES & TOOLS.
RULE 1 : Check for previous work:
Look around on the web to see if someone else has already fact-checked the claim.
TOOL : Use "site" in a search - try this (copy & paste) australia 600lb woman 40lb baby site:snopes.com
RULE 2 : Go upstream to the source:
Go “upstream” to the source of the claim. Most web content is not original. Get to the original source to understand the trustworthiness of the information.
TOOL : Use a Google search to find the ORIGINAL article if a source is quoted from.
RULE 3: Read laterally:
Once you get to the source of a claim, read what other people say about the source (publication, author, etc.).
RULE 4: The truth is in the network:
If you get lost, or hit dead ends, or find yourself going down an increasingly confusing rabbit hole, back up and start over knowing what you know now. You’re likely to take a more informed path with different search terms and better decisions.
