For this thread, I'd like to examine some of the techniques used in detecting false accounts given multiple different tellings, and then apply those techniques to the post-resurrection appearance accounts in the gospels and try to determine whether the gospel accounts are trustworthy evidence of a resurrection or not. For this purpose, I think we can ignore the 'empty tomb' story, and just stick to the appearances, which occur in Matt. 28:16–20, Luke 24:13–53, and John 20:11—21.1
When we apply whatever lie-detecting tools we might have to the accounts of Jesus' post-resurrection appearances, what can we conclude about the veracity of the claims? And, if the claims are likely true, does this validate the resurrection account? If the claims are likely false, does this invalidate it?
When we interrogate the apostles, do we find them lying or telling the truth?
