What good is moral reasoning?

an article by Hugo Mercier published in Mind & Society Volume 1 Number 2 (December 2011)

Abstract
The role of reasoning in our moral lives has been increasingly called into question by moral psychology. Not only are intuitions guiding many of our moral judgments and decisions, with reasoning only finding post-hoc rationalisations, but reasoning can sometimes play a negative role, by finding excuses for our moral violations. The observations fit well with the argumentative theory of reasoning (Mercier H, Sperber D, Behav Brain Sci, in press-b), which claims that reasoning evolved to find and evaluate arguments in dialogic contexts. This theory explains the strong confirmation bias that reasoning displays when it produces arguments, which in turn explains its tendency to rationalise our decisions. But this theory also predicts that people should be able to evaluate arguments felicitously and that, as a result, people should reason better in groups, when they are confronted with other people’s arguments. Groups are able to converge on better moral judgments. It is argued that reasoning and argumentation play an important role in our everyday moral lives, and a defence of the value of reasoning for moral change is offered.
