Trust me, Umbran: there's a reason why the basic degree in Econ is a BA, NOT a BS (though it really oughtta be). 
Econ is too variable to truly be science...at least, at this point in time. This is one thing that fans of Albert Laffer's supply-side economic theory don't understand. While Economics uses the scientific method, terminology and even some of the high-end math of hard science, results can vary wildly and conform to more than one school. It has too many soft variables that cannot be controlled for, including human irrationality. It has more descriptive than predictive power.
