What is it about topics like incest, bestiality, necrophilia and cannibalism that urges us to pick up pitchforks and torches? A more important question, however, is whether these topics automatically or necessarily should elicit outrage enough for us to target those who perform these acts. I think not.

Considering the purely descriptive side, there has been some interesting but controversial research into our moral psychology and intuitions.

Jonathan Haidt famously provided the following example in a study.

Julie and Mark are brother and sister. They are travelling together in France on summer vacation from college. One night they are staying alone in a cabin near the beach. They decide that it would be interesting and fun if they tried making love. At the very least, it would be a new experience for each of them. Julie was already taking birth control pills, but Mark uses a condom too, just to be safe. They both enjoy making love, but they decide never to do it again. They keep that night as a special secret, which makes them feel even closer to each other. What do you think about that? Was it ok for them to make love?

Haidt, in an interview, explained the responses of subjects reaching ‘moral dumbfounding’:

People almost always start out by saying it’s wrong. Then they start to give reasons. The most common reasons involve genetic abnormalities or that it will somehow damage their relationship. But we say in the story that they use two forms of birth control, and we say in the story that they keep that night as a special secret and that it makes them even closer. So people seem to want to disregard certain facts about the story. When the experimenter points out these facts and says “Oh, well, sure, if they were going to have kids, that would cause problems, but they are using birth control, so would you say that it’s OK?” And people never say “Ooooh, right, I forgot about the birth control. So then it is OK.” Instead, they say, “Oh, yeah. Huh. Well, OK, let me think.”
