Pentagon's Prediction Software Didn't Spot Egypt Unrest

In the last three years, America's military and intelligence agencies have spent more than $125 million on computer models that are supposed to forecast political unrest.

The head of the CIA is getting hauled in front of Congress, making calls about Egypt's future based on what he read in the press, and getting proven wrong hours later.

"All of our models are bad, some are less bad than others," says Mark Abdollahian, a political scientist and executive at Sentia Group, which has built dozens of predictive models for government agencies.
