Factiness is a term that refers to the use of factual-sounding information that is actually exaggerated or false. Synonyms for factiness might include misleading, deceptive, inaccurate, or distorted information. Other words that could be used to describe factiness include disinformation, misinformation, falsity, fallacy, or spuriousness. Factiness can be especially insidious because it can be difficult to distinguish from real facts, and it often takes advantage of people's willingness to believe information that seems authoritative or convincing. Therefore, it's important to be cautious and critically evaluate any information that seems too good (or bad) to be true.
