Jonathan Haidt on 5 moral foundations, and political differences

Another fascinating TED lecture : Jonathan Haidt on the moral roots of liberals and conservatives.

Have encountered quite a few articles on this theme (e.g. those mentioned in previous blog post here) but Haidt presents not only some light liberal/conservative trait differences, but a concept for the underlying innate foundation of morality which these stand on.

So, in stark contrast to a 'blank slate' at birth, Hadit proposes we have a 'first draft' of morality, which he explains with a quote from the brain scientist Gary Marcus. "The initial organization of the brain does not depend that much on experience. Nature provides a first draft, which experience then revises. Built-in doesn't mean unmalleable; it means organized in advance of experience."
Haidt wanted to determine what such a first draft would be, and since it would need to be universal, studied the literature on anthropology, culture variation in morality etc. i.e. as he says "What are the sorts of things that people talk about across disciplines? That you find across cultures and even across species?"
As a result of this they identified 5 best matches, which they call the 5 foundations of morality, to quote (with some omissions) from the TED lecture:

1. harm/care. We're all mammals here, we all have a lot of neural and hormonal programming that makes us really bond with others, care for others, feel compassion for others, especially the weak and vulnerable. It gives us very strong feelings about those who cause harm. This moral foundation underlies about 70 percent of the moral statements I've heard here at TED.
2.  fairness/reciprocity. e.g. "The Golden Rule," and we heard about this from Karen Armstrong, of course, as the foundation of so many religions. That second foundation underlies the other 30 percent of the moral statements I've heard here at TED.
3. in-group/loyalty. And this tribal psychology is so deeply pleasurable that even when we don't have tribes, we go ahead and make them, because it's fun. (Laughter) Sports is to war as pornography is to sex. We get to exercise some ancient, ancient drives.
4. authority/respect. But authority in humans is not so closely based on power and brutality, as it is in other primates. It's based on more voluntary deference, and even elements of love, at times.
5. purity/sanctity. This painting is called "The Allegory Of Chastity," but purity's not just about suppressing female sexuality. It's about any kind of ideology, any kind of idea that tells you that you can attain virtue by controlling what you do with your body, by controlling what you put into your body. And while the political right may moralize sex much more, the political left is really doing a lot of it with food. Food is becoming extremely moralized nowadays, and a lot of it is ideas about purity, about what you're willing to touch, or put into your body.

Surveys of how people prioritized these values, showed reliable differences between liberals and conservatives, even in different countries. While all were agreed that harm/care and fairness were important, they were slightly more important to liberals than conservatives. Where there was much more difference however, was with respect to the other 3 foundations : in group loyalty, authority and purity. These were ranked significantly less than harm/care and fairness by liberals, but the more conservative the subject, the more important these pillars of morality became : 

                                       

The point being made is that all 5 elements are important to morality as resulting from our nature, so none can be dismissed, but people of different political stripe differ in their emphasis. This is not to be relativistic, since in certain times and certain societies some values maybe should take priority over others. Of course while it might be easy for liberals to point out how over adherence to in-group loyalty and authority might lead to things such as authoritarianism and xenophobia, it could also be argued that extreme fairness could be seen as the basis for forced communism, with disregard for individual rights. So these insights do not provide easy answers, but do suggest how we can work towards answers : namely to appreciate that all these strands are fundamental to our societies, and that we need to step back from our own personal convictions to see the whole picture, and properly evaluate the priorities of others. They may not be right, but then again we might not be either. 

Personally I find the whole area of moral psychology one of the most fascinating and challenging, since it cuts to the core of many of the most important issues, both at a personal and a cultural level - how we should live our lives and run our societies. As the ancient greek aphorism suggests, to know what to do, first know thyself, and these studies show science can help us in this, even in such seemingly unlikely and intangible fields as morality.
