How can you be disingenuous if you don't know what you're talking about?

[aaronblohowiak]

I think the sky is red but I tell you today it is teal -- I am lying about something I misunderstand

[mistermann]

Does "lying" not imply one knows the truth?

[jasonlotito]

No. It implies one is attempting to pass of a false statement as true. If you know your statement is false, you are lying. Just because you don't know the truth doesn't mean you can't lie.
