Technically, that falsehood is what makes it a factoid, since it resembles-but-isn't a fact, just like how a spheroid is not a true sphere, a meteoroid/asteroid isn't a true meteor/star, an android/gynoid isn't a true man/woman, and almost every other -oid word out there.
Now, there are some philistines out there who claim that popular misuse means the "correct" definition of factoid has changed recently... But either way, I still find it amusing that everyone agrees that "A factoid is a small fact" is itself a factoid.
