Jonathan Haidt's Moral Foundations Theory

Jonathan Haidt is a moral psychologist who teaches at New York University. In his 2012 book The Righteous Mind, he proposes a model for understanding people's moral intuitions called Moral Foundations Theory.

Haidt adapts the concept of cognitive modules proposed by cognitive anthropologists. Cognitive modules are neural pathways with which the brain is prewired, and which respond to patterns detected by the senses. For example, Dan Sperber and Lawrence Hirschfield have proposed that people possess a snake-detector module. Our brains appear to be prewired to produce a fear response as soon as we see a snake whether or not we have been taught to fear snakes, and whether or not we have ever seen a snake. (144)

Haidt and his colleague Joseph Craig borrow this idea of modularity and propose that humans have six moral intuition modules. Haidt calls these modules “moral foundations,” and this is why the theory is known as Moral Foundations Theory. The six modules are Caring/harm, Fairness/cheating, Loyalty/betrayal, Authority/subversion, Sanctity/degradation, and Liberty/oppression. (146, 197)

To demonstrate how Moral Foundations Theory works, Haidt asks the reader to imagine their child undergoing surgery. The idea of a sharp implement piercing your child is obviously disturbing even if you understand that the procedure is for your child’s benefit. If you imagine morality to be based on reason, then it makes no sense for you to turn away. But if your moral intuitions are reflexive responses to particularly stimuli, then the compulsion to look away during the surgery despite your knowledge that the surgery is beneficial makes perfect sense. Similarly, Haidt asks you to imagine that one of the nurses assisting in the surgery strokes your child’s head while they undergo the surgery. Would you not be comforted by this act even if it were the case that your son was entirely oblivious to this action? And if there were two nurses assisting in the surgery, and both were equally competent, would you not prefer the nurse that stroked your child’s head despite this act being of no consequence to the outcome of the surgery or even your child’s comfort during the surgery? Haidt argues that there is no rational reason to view the nurse’s action as a “good” act, but we would all intuitively feel that it is. Again, Haidt argues, this makes perfect sense if our emotions are simply intuitions triggered by particular stimuli. (147-8)

For Haidt, we all have six moral intuition modules, but the content of those intuitions varies. Our Care/harm moral intuition might extent to only our family. Or it might extend to our tribe, not beyond that. Or perhaps only to our nation, but not foreigners. We have the same innate capacity for empathy, but we do not innately extend it to the same universe of people.

What determines the content of our moral intuition modules? First, there are genetic differences between people that either increase or decrease the degree to which they lean on certain modules. For instance, some genes make novel experiences more pleasurable. Such a person would have less need for order and structure and would therefore be less inclined to highly value submission to authority. In addition, elements of our personality are developed in response to our environment. If we attend a rigidly structured school that causes us to disengage, disengagement might become a personality trait. Adding to this variation are differences in our experiences. One person might choose to regularly attend church, whereas another might not. Such differences in experience can potentially enhance differences in the content of moral intuitions. (322-28)

Haidt believes that political divisions within society can be explained in part by difference in the degree to which any particular moral intuition module is active for a given political grouping. Educated Westerners such as professors and university students tend to be highly motivated by the Care/harm, Fairness/cheating, and the Liberty/oppression foundations. Such people are liberals in the context of American politics. For example, they might have bumper stickers expressing solidarity with distant people whom they have never met, such as the victims of the Darfur genocide. (156-7) If educated Westerners feel any sense of sanctity, it is less likely to have to do with religion than with civil rights leaders, for instance. (123)

However, educated Westerners are both globally and historically unique. Much of Haidt’s research is based on surveys, and he recounts how working class people just down the road from his university responded drastically differently than his colleagues and students to his survey questions. (111) Some psychologists apparently now use the acronym WEIRD to refer to cultures that are Western, educated, industrialized, rich, and democratic. They do so to highlight that such cultures “are the least typical, least representative people you could study if you want to make generalizations about human nature.” (112) Furthermore, Americans are WEIRDer than Europeans, and the best educated Americans the WEIRDest of all. Haidt concludes that this is because “Liberals have a three-foundation morality, whereas conservatives use all six.” (214) Most people globally and historically have apparently made greater use of all six moral intuition modules.

Haidt believes that our moral matrices have blind spots. For instance, Haidt writes that in the 1960s liberals pushed for programs that supported the poor but which undermined institutions such as the family. Driven by a strong moral intuition about the need to provide care, but lacking significant concern for loyalty, authority, and sanctity, liberals harmed those they sought to help. Haidt seems to imply that if liberals had taken social conservative arguments more seriously, welfare programs might have been crafted in such a way as to mitigate these harms. (356-62)

Haidt wants his readers to consider their moral matrices’ blind spots and to consider the virtues of other moral intuition modules. He therefore spends about twenty pages describing the virtues of various political persuasions. Liberals are correct in that regulation is sometimes beneficial. Libertarians are right that markets promote innovation. Etc. Perhaps, he writes, “…public policy might really be improved by drawing on insights from all sides.” Indeed, he thinks liberals and conservatives are the complimentary yin and yang of a well-functioning society. (343-4)

On the one hand, I certainly endorse the proposal that we strive to overcome our tribalism. As Sam Harris has pointed out, the fact that one’s position on abortion is predictive of their position on gun control is a problem. Issues such as these are not sufficiently related to justify an almost certain correlation between them. There is no obvious reason why someone could not be opposed to abortion but in favor of strict gun control. Therefore, if we are able to predict someone’s position on the one issue by knowing their position on the other, it suggests that we are not thinking critically for ourselves but simply adopting positions taken by our tribe.

On the other hand, maybe there’s a good reason that the best educated people in human history have unique attitudes about morality. And perhaps if we crafted public policy that drew “on insights from all sides” we would merely dilute the moral intuitions of people who have most escaped our worst impulses to exclude and oppress.

Whether one buys that or not, Haidt’s prescriptions have only a tenuous connection to his descriptions. Just as individuals and groups have blind spots in all other realms, we have blind spots when it comes to morality. And such blind spots can be compensated for by a diversity of perspectives. However, as I think he would agree, there is nothing about his descriptive taxonomy of moral intuition modules that closes the door on the possibility that some groups really are, to put it bluntly, morally superior to others.
