Lakatosian Consolations for Economics

Abstract
The F-twist is giving way to the methodology of scientific research programs. Milton Friedman's “Methodology for Economics” is being supplanted as the orthodox rationale for neoclassical economics by Imre Lakatos' account of scientific respectability. Friedman's instrumentalist thesis that theories are to be judged by the confirmation of their consequences and not the realism of their assumptions has long been widely endorsed by economists, under Paul Samuelson's catchy rubric “the F-twist.” It retains its popularity among economists who want no truck with methodology, but among the increasing number of able economists who are writing on methodology the F-twist has been surrendered, not so much because these writers have decided it is false, as because something better has finally come along.
