4 How to Use Previous Work

When fact-checking a particular claim, quote, or article, the simplest thing you can do is to see if someone has already done the work for you.

This doesn’t mean you have to accept their finding. Maybe they assign a claim “four Pinocchios” and you would rate it three. Maybe they find the truth “mixed” but honestly it looks “mostly false” to you.

But regardless of the finding, a reputable fact-checking site or subject wiki will have done much of the leg work for you — tracing claims to their source, identifying the owners of various sites, and linking to reputable sources for counterclaims. And that legwork — no matter what the finding — is probably worth ten times your intuition. If the claims and the evidence they present ring true to you — or if you have built up a high degree of trust the site — then you can treat the question as closed. But even if you aren’t satisfied, you can start your work from where they left off.

Constructing a Query to Find Previous Fact-Checking

You can find previous fact checking by using the “site” option in search engines such as Google and Duck Duck Go to search known and trusted fact checking sites for a given phrase or keyword. For example, if you see this story:

Screenshot of article with headline reading \"MORE HYPOCRISY: Obama Banned all Iraqi Refugees for 6 Months in 2011 - Liberals SAID NOTHING!\"


Then you might use this query, which checks a couple known fact-checking sites for the keywords ‘obama iraqi refugee ban 2011’. Let’s use the Duck Duck Go search engine to do this:

obama iraqi visa ban 2011 site:snopes.com site:politifact.com

Here’s what we get back for results:

You can see the search here. You see that work has already been done in this area — in fact, the fist result from Snopes answers our question pretty fully. Remember to follow best search engine practice — scan the results, looking at the URLs and the blurbs to find the best result to click in the returned result set.

There are similar syntaxes you can use in Google, but for various reasons this particular search is easier in Duck Duck Go.

Let’s look at another claim — this one from the President. This claim is that police officer deaths increased 56 percent from 2015 to 2016. Here it is in context:

Section from a Trump speech reading \"We must protect those who protect us. The number of officers shot and killed in the line of duty last year increased by 56 percent from the year before. Last year, in Dallas, police offĂ­cers were targeted for execution - think of this. Who ever heard of this? They were targeted for execution .\" The sentence that mentions the increase is highlighted.

From a Trump speech

So let’s ramp it up with a query that checks four different fact-checking sites:

officer deaths 2016 increased 56 percent from 2015 site:factcheck.org site:snopes.com site:politifact.com site:www.washingtonpost.com/news/fact-checker/

This gives us back a helpful array of results. The first, from the Washington Post, actually answers our question directly, but some of the others provide some helpful context as well:

Duck Duck Go search results. The search returns numerous articles from fact-checkers checking this specific claim.

Going to the Washington Post site we find out that this claim is for all intents and purposes true. We don’t need to go further, unless we want to.
