Things that make you go hmmmm

Raise your hand if you actually parsed this paragraph from Dani Rodrik's guest blogger, Arvind Subramaniam, on first reading:

The World Bank’s statisticians have changed the economic facts. Under these circumstances, Keynes, the economist, would have us change our opinions, while the great scientist, Einstein, would have us tamper with the facts especially if they clash with our theoretical priors. Which should it be? A little bit of both, it seems.

The hardest thing for economists, when writing for a popular audience, is remembering all the things they didn't know before they were economists.
