I was always down with Edgar Allan: “Believe nothing you hear, and only one half that you see”

But now I think he was vastly over-optimistic.

I’ve heard a different version “believe nothing you hear, and only half of what you read”, variously attributed to Mark Twain, Einstein, Benjamin Franklin and Douglas Adams.

I guess that proves their point, whoever they were.
