 Buchanan and Powell refer to this pessimistic idea as “evoconservatism,” and they note that it has been used to argue against social and political movements organized around such “cosmopolitan moral reform.” And on the other side of that same evolutionary coin, “evoliberals” share the same premise about the constraints imposed by evolution on human moral psychology but instead argue that since the progressive goals are sufficiently desirable, we should look for biotechnological interventions to alter human nature in such a way as to make them realistically achievable. Buchanan and Powell reject both views because they reject the underlying picture of evolved human moral nature. Instead, they argue that the striking shifts that have already occurred toward more inclusive morality, as well as consideration of the conditions under which moral regression has occurred, support a very different, more nuanced picture of evolved human moral psychology—one without such pessimistic implications for deep and lasting moral progress.
