 Recently, Joshua May (2018) has challenged the primacy of affect in moral thought on empirical grounds. He argues that the best evidence we have supports only a more modest role for emotions as facilitating (or hindering) information processing. May notes that manipulating incidental emotions – that is, emotions that are not directed towards or aroused by the object of moral judgment, such as disgust caused by foul odors (Schnall et al. 2008) – has only been found to have minor effects. He rightly points out that such scarce and minor effects don’t support any claims about a leading or essential role for affect in moral judgment. Following Heidi Maibom (2005), he also argues that problems in the moral judgment of psychopaths are better explained by rational rather than emotional deficits.
