Is there some misunderstanding in English that “biased” means “factually false”? I’ve seen a lot of people on the internet confuse them as the same thing. Bias is supposed to mean something that is factual but presenting a one-sided opinion by e.g using a subset of facts and language meant to influence the readers opinion.
