The issue with "dishonest" is that honesty implies intent. A statement has no intent, so it can't be honest or dishonest. A statement can only be right or wrong. An author can be honest or dishonest. An honest author can be wrong, and a dishonest author can be right. But to say that a statement is "dishonest" is to call the author, in the context of writing the statement, dishonest.
