Turns out the fancy math mania among economists didn't help us leading up to and during the great recession. We should now go back and pick up again the lessons learned after the Great Depression (like Keynes' Animal spirits). Math and models are still important (they are in fact essential, without them we can't think clearly or rigorously enough) but they and their interpretations have to take into account the complexity of human nature to a greater extent, not rely on a simplistic and almost non-existent homo economicus.
