that which has been shown to be erroneous
Falsehood does not mean incorrect but in error. In other words, what is presented may be absolutely accurate and yet not reflect what is really going on. Perhaps only a portion of the truth is expressed or more information than is pertinent causes one to misconstrue. A danger is that Falsehood can get away from the control of its creator. Once an error has been passed off as truth, some will continue to accept it as truth even if it is recanted by the person that gave the False account.
