I'm not sure if the picture makes sense. I guess there are two ways to interpret the size of the books: (a) bigger book about X = more ways to do X, (b) bigger book about X = more difficult to do X.
I guess (a) can't be right, because clearly there cannot be fewer ways to lie in general than there are ways to lie with statistics or lie without statistics (the latter two are subsets of the first).
But (b) doesn't seem right to me either. It would mean first that it is harder to lie using statistics than it is just to lie in general -- fair enough I think (see also my signature!!) -- but then it is also harder to lie without statistics than it is to lie with statistics? That doesn't seem consistent.
Where is this picture from? What is it supposed to mean exactly?
