> will simply lie, as with a biased human opinion Is this really how bias works?
Oh no. Definitely not. Humans would never just lie. They always lie only if they're biased. That is, after all, the definition of how a bias works. /s
EDIT: actually I'm really not sure what hairs we're trying to split here. I see bias as a departure from objectivity. It can be conscious or unconscious, but when someone is selling something, it's frequently conscious and self-serving, and I believe that's referred to as a lie.
