Title is inherently wrong.

If a belief I hold is wrong, then I don't know it, I merely believe it.

Before you accuse me of being pedantic here: this isn't just semantics. Ostensibly the author means that I the things I believe I know are wrong, but this is just a cheap clickbait technique. The author can't possibly know what I believe to tell me it's wrong.

Maybe the author wants to say that a commonly-held belief is wrong. Maybe the author just wants to share some facts. Either way, I'll never know, because the author decided to make blatantly incorrect and somewhat condescending statements in the title. There's no way I'm going to reward that bad writing and bad behavior by clicking the link.
