If you tell someone something that isn’t true but you believe it to be true, is it a lie?  
The noun definition of a lie is “a statement that deviates from or perverts the truth.”  But the verb definition is “to tell an untruth; pretend with intent to deceive.”  The noun definition indicates that the answer to my original question is yes because a falsehood is a lie no matter your beliefs or intent.  But the verb definition takes into account your intentions, indicating that you must intend to deceive.  
So which is the right answer?
