The difference is, that with lies, you have to know it is untrue and say it anyway, where with misinformation, there is a possibility that the one telling it believes it is true.

Well that is how I understand the word lying defined: Say something you know is not true in order to manipulate others.

Or again different said: a lie is always misinformation, but misinformation is not always a lie.

Hope that is understandable 😇
