Everything you know is wrong
If you have ever doubted the usability of a liar’s typical statement “everything you know is wrong” apparently suits well as catchline for a book about disinformation. And You are being lied to is of course the truth of another book, isn’t it?
Even when the title becomes more specific like in Everything you know about sex is wrong it’s no less of a truth as any self-contradictory statement.
Don’t forget:
Everything you know about blogging and me is wrong. This in particular.
