"We have demonstrated that moral reasoning can be influenced by motivations that may have nothing to do with moral concerns.
Disgust has been keeping us particularly busy, as it has been implicated by many as an emotion that plays a large role in many moral judgments.
In our lab, we have shown that an increased tendency to experience disgust (as measured using the Disgust Sensitivity Scale,
developed by Jon Haidt and colleagues), is related to political orientation.
We have shown that even for people who may not be willing (or aware) of their attitudes toward homosexuality,
the degree of disgust sensitivity predicts so-called "implicit" attitudes toward homosexuality.
Finally, in ongoing work we have shown that manipulating disgust with a noxious odor leads to greater antipathy "toward gays and lesbians",
but does not shift attitudes that might be associated with liberal or conservative beliefs.
I also have a general interest in the influence of emotional states on thinking and deciding.
I am particularly interested in specific emotions (anger, disgust, fear, etc.), and on "visceral" affective states
(e.g., thirst, hunger, sexual arousal) and their impact on how we process information,
how we remember events, and how these emotions impact our moral judgments"
