We have looked, but there is no single fact-checking tips checklist that covers all the different types of evidence you might have to assess before you decide a claim is sound.
Listed below are the main questions we ask.
Could they know what they claim to know?
If the evidence is based on an eyewitness account, could the person know what they claim to know?
Were they there? Is it likely that they would have access to this sort of information? Is the information first-hand? Or is it second-hand, something they had heard and believed? Is it something that could be known?
