This afternoon I was reading through the primary literature on political morality, particularly regarding Jonathan Haidt’s 5-dimensional morality scale. In summary, Haidt models morality as consisting of five components:
- Harm/Care
- Fairness/Reciprocity
- Ingroup/Loyalty
- Authority/Respect
- Purity/Sancity
In other words, what one finds morally right or wrong can be decomposed into contributions along these dimensions. Haidt has also argued quite convincingly that the foundations of morality are intuitive, rather than reasoned – that is, the reasons given for morality are post hoc constructions of intuitive evaluations that can be broken down into these five components.
Haidt and colleagues argue here that liberals and conservatives differ in the relative contributions of these five components to their intuitive morality:
Here, Haidt and colleagues ask self-identified liberals and conservatives to evaluate a series of statements designed to assess the respect contributions of each to their morality. For example:
- Harm/Care: “Compassion for those who are suffering is the most crucial virtue”
- Fairness/Reciprocity: “If a friend wanted to cut in with me on a long line, I would feel uncomfortable because it wouldn’t be fair to those behind me”
- Ingroup/Loyalty: “The government should strive to improve the well-being of people
in our nation, even if it sometimes happens at the expense ofpeople in other nations”
- Authority/Respect: “If I were a soldier and disagreed with my commanding officer’s orders, I would obey anyway because that is my duty”
- Purity/Sancity: “People should not do things that are revolting to others, even if noone is harmed”
Haidt’s main finding, as seen on the graph, is that conservative morality has increased contributions from ingroup/loyalty, authority/respect, and purity/sanctity. Of course, this is all quite intuitive for anybody who knows the conservative mind, but it is worth reminding liberals that there are fundamental differences in morality across the political spectrum – incidentally, there exists preliminary work in neuroscience linking these differences to changes in brain structure, particularly the amygdala and anterior cingulate cortex, something I will post on another day.
However, the part of this study that I wanted to draw attention to was ‘Study 3′. Here they ask individuals ‘to indicate how much money someone would have to pay you’ to violate each of the different categories. For instance:
- Harm/Care: Kick a dog in the head, hard
- Fairness/Reciprocity: Steal from a poor person and use the money to buy a gift for a rich person
- Ingroup/Loyalty: Publicly bet against your favorite sports team
- Authority/Respect: Curse the founders or early heroes of your country
- Purity/Sancity: Cook and eat your dog, after it dies of natural cause
Again here, Haidt and colleagues find that conservatives require greater incentive to violate the three latter moral dimensions (and slightly less incentive to violate the harm dimension).
But the interesting part to me was this:
Because we had a large sample of libertarians, who are usually ignored in political–psychological research, we compared their sacredness reactions to those of liberals and conservatives. Overall, libertarians showed less refusal to violate the foundations for money than did liberals or conservatives.
The libertarian, in every category, was more likely to sell out morality than both liberals and conservatives. Yes, we can add important caveats (i.e. this is based on self-report; it would be nice to see some controls for age/sex), but I found this quite striking. In some respects it’s obvious – libertarians don’t see any need for regulations, since they have fewer moral scrupples – but it was nice to see this quantified.
