Clearly the use of models to predict things is not a great way to go. As the 'Black Swain' suggested models almost always underestimated or discount the extremes, Also it does not take in account group think or group behaviour. Which seems to more pronounced in the extreme good times and extreme bad times. We need a new combined discipline of Physiology and Economics. I think you could start now and use the last 10 years to build great models that explore group think in investing.
