Heterodox economists, along with many non-economists, have often leveled charges of ideological bias against mainstream economics and economists. This paper considers some of these charges, arguing that most heterodox arguments about the mainstream’s ideological bias are not persuasive. An argument can, however, be made that the mainstream is unintentionally ideologically biased because it supports the status quo without taking a position on whether there is an alternative position that is preferable. Ironically, the reason that mainstream economics can be considered ideologically biased is that it works so hard at avoiding considering ideological issues.
