This is a draft of a chapter for the Routledge Handbook of Metaethics, edited by David Plunkett and Tristram McPherson. I offer an overview of hybrid views in metaethics, with main focus on hybrid cognitivist views such as those defended by Daniel Boisvert and David Copp, and on hybrid expressivist views such as those defended by Michael Ridge and myself.

In Unbelievable Errors, Bart Streumer argues via elimination for a global error theory, according to which all normative judgments ascribe properties that do not exist. Streumer also argues that it is not possible to believe his view, which is a claim he uses in defending his view against several objections. I argue that reductivists and nonreductivists have compelling responses to Streumer's elimination argument – responses constituting strong reason to reject Streumer’s diagnosis of any alleged incredulity about his error theory.

I argue that there are cases in which ecumenical expressivism cannot distinguish between endorsement of certain trivial and substantive normative judgments. I consider the extent to which this problem generalizes across different formulations of the ecumenical view. I suggest that we may not be able to escape the problem if we hope to retain the ability to solve the Frege-Geach problem in the way promised by ecumenical expressivism.
