Fact-checking
Fact-checkers rate claims false, misleading, or unsupported based on an analysis of the evidence and arguments
- Evidence is an established fact that makes a claim more (or less) probable than it would be otherwise.
- An argument is a piece of reasoning from premises to a conclusion, typically set forth to prove or disprove a claim.
Main Ratings
- False means that the claim has been shown to be false.
- Synonyms: untrue, wrong
- Misleading means that the claim is true but apt to mislead
- Unsupported means that the claim has not been established
- Synonyms: baseless, groundless, no basis in fact, unsubstantiated, unfounded, lacks evidence, no evidence
The words”establish,” “show,” and “prove” mean to prove beyond a reasonable doubt, based on the evidence and arguments.
Examples
Claim Rated False
- Claim
- Biden visited New York City the day after 9/11.
- factcheck.org
- The Congressional Record notes that Biden was in the Senate that day, and C-SPAN footage documents that he spoke briefly from the floor.
- Thus the claim has been shown to be false.
Claim Rated Misleading
- Claims
- There are more Americans working today than ever before in American history. (Mike Pence 2017)
- In fact, there are more people working in America than at any point in American history. (Joe Biden 2022)
- Washington Post Fact Checker
- Of course there are more Americans working. That’s because there are more Americans today than ever before. More meaningful measures of the overall health of the job market take population into consideration.
- Thus the Pence and Biden claims are true but apt to mislead.
Claim Rated Unsupported
- Claim
- While president, Trump declassified all the secret documents in his possession.
- CNN Facts First
- Trump and his team have not provided any proof that Trump actually conducted some sort of broad declassification of the documents.
- Eighteen former top Trump administration officials, including two former White House chiefs of staff who spoke on the record, said that they never heard of a standing Trump declassification order when they were serving in the administration and that they now believe the claim is false.
- Thus the claim has not been established by the evidence.

Burden of Proof and Standard of Evidence
- Burden of Proof
- politifact.com/article/2018/feb/12/principles-truth-o-meter-politifacts-methodology-i/
- The burden of proof is on the speaker, and we rate statements based on the information known at the time the statement is made.
- factcheck.org/our-process/
- Once we find a statement that we suspect may be inaccurate or misleading, we will engage – or attempt to engage – with the person or organization that is being fact-checked. The burden is on the person or organization making the claim to provide the evidence to support it.
- politifact.com/article/2018/feb/12/principles-truth-o-meter-politifacts-methodology-i/
- Standard of Evidence
- washingtonpost.com/news/fact-checker/about-the-fact-checker/
- We will adopt a “reasonable person” standard for reaching conclusions. We do not demand 100 percent proof.

What evidence do you have?
factcheck.org (2016)
- It’s a simple question, one that we ask candidates, campaigns and political committees all the time: “What evidence do you have?”
- That’s why we were heartened to see NBC’s Lester Holt ask Trump “what evidence do you have” to support two of Trump’s claims in a June 22 speech that we and other fact-checkers found contained numerous false claims.
- In an interview with NBC’s Lester Holt, Trump claimed that Clinton’s email server had been hacked? Lester Holt asked “What evidence do you have?”
- When that didn’t elicit a response, Holt asked again, “But is there any evidence that it was hacked other than routine phishing?” Trump finally said that he heard or read about Clinton’s email being successfully hacked. Asked where he got that information, Trump said, “I will report back to you. I’ll give it to you.”
- We would like to see more TV news anchors challenge the presidential candidates on statements that fact-checkers universally agree are false and misleading, especially those that are made without any evidence. It just takes a simple question, “What evidence do you have?”
