The epistemology of Heterodox Economics has been described as a type of methodological pluralism where its relativism is taken as consistent with new versions of science. However, methodological pluralism has severe drawbacks as a means of inquiry. Whereas Economics is often understood in positivist terms as a closed set, Heterodox Economics includes additional concepts and methods. As an open set of ideas, Heterodox Economics is a means to doubt or to not-know and comprises Einfühlung or the creative intuition for the introduction of new ideas into the epistemology of Economics.
