Disgust

 The NY Times has a story about the emotion of disgust, focusing on the work of psychologists Paul Rozin and (his student) Jonathan Haidt.  It focuses on some of the ways that biological/psychological notions of disgust can be carried over to disapproval of more political kinds (and of the kinds of transactions that some people disapprove of involving what economists have started to call repugnance).

Here's the Times' story:

How Disgust Explains Everything. For psychologists who study it, disgust is one of the primal emotions that define — and explain — humanity.  By Molly Young

"Haidt continued to zero in on the political uses of the word, noticing that Americans often listed as “disgusting” such things as racism, brutality, hypocrisy and ambulance-chasing lawyers. “Liberals say that conservatives are disgusting. Conservatives say that welfare cheaters are disgusting,” he wrote in a paper with Rozin and two others in 1997.* What was that about? Was the use of “disgust” for such a wide range of activities simply a metaphoric quirk of the English language? Did the pundits who sat around all day expressing disgust on TV have to keep a vomiting bucket next to their desks, or were they just being linguistically imprecise?

"Neither, exactly. When Haidt and Rozin looked at other languages, they found that many contained words with a compound meaning equivalent to “disgust” — single words that could be applied to both legislation and diarrhea. German had ekel. Japanese had ken’o. Bengali had ghenna. Hebrew had go-al. When an Israeli woman was asked what situations made her feel go-al, she cited “a horrible accident and you see body parts all over the place” and a person “who just picked his nose and ate it later.” But she also said that “If you really dislike a politician, you would use the word go-al.”

...

"These two types of human — which broadly map onto “liberal” and “conservative,” or “relatively disgust-insensitive” and “relatively disgust-sensitive” — live in separate moral matrices. If it seems bizarre that disgust sensitivity and politics should be so closely correlated, it’s important to remember that disgust sensitivity is really measuring our feelings about purity and pollution. And these, in turn, contribute to our construction of moral systems, and it is our moral systems that guide our political orientations."

Who finds sales of genetically modified food repugnant? (Hint: they are disgusted)

Here's a paper on a source of firm opposition to genetically modified food:

Sydney E. Scott, Yoel Inbar, and Paul Rozin
Evidence for Absolute Moral Opposition to Genetically Modified Food in the United States
Perspectives on Psychological Science May 2016 11: 315-324

Abstract

Public opposition to genetic modification (GM) technology in the food domain is widespread (Frewer et al., 2013). In a survey of U.S. residents representative of the population on gender, age, and income, 64% opposed GM, and 71% of GM opponents (45% of the entire sample) were “absolutely” opposed—that is, they agreed that GM should be prohibited no matter the risks and benefits. “Absolutist” opponents were more disgust sensitive in general and more disgusted by the consumption of genetically modified food than were non-absolutist opponents or supporters. Furthermore, disgust predicted support for legal restrictions on genetically modified foods, even after controlling for explicit risk–benefit assessments. This research suggests that many opponents are evidence insensitive and will not be influenced by arguments about risks and benefits.

Is economic repugnance closely related to biological disgust?

Colleagues often send me articles related to this blog, but the one I have received the most copies of recently is yesterday's NY Times article: Survival’s Ick Factor, about recent studies related to the emotion of disgust, and its possible evolutionary significance in e.g. keeping people away from sources of infection such as feces.

Many people have sent me the article because of my own interest in ickonomics, aka repugnant markets and transactions. A repugnant transaction is one that some people want to engage in, and others think they shouldn't be allowed to. I'm willing to exclude the case of ordinary, pecuniary negative externalities. The issue that initially made all of this very salient to me is the ban, almost everywhere, on buying and selling kidneys (which generated my interest in kidney exchange). But I quickly realized that there are lots of repugnant transactions, and I began a 2007 article on the subject by asking why you can't eat horse meat in California. (It's against the law, passed by popular referendum in 1998.)

Which brings me to the point of this post.

I don’t think the kind of repugnance I study is fundamentally related to biological/evolutionary disgust. The reason there are laws against eating horsemeat, for example, is that it isn’t innately disgusting, so some people want to do it, and others don’t want them to. But there aren’t any laws against eating feces…(sorry, yuck).

Now, I bet that your brain is economical, and that you might recruit some of the same neurons you use to feel disgust to remind you of things you don't like. So I'm not surprised that there are correlates between propensity to feel disgust and some political opinions, for example.

But, to come back to kidney sales, I can't see that the repugnance to selling transplant kidneys for money can be closely related to the disgust that may be inspired by transplantation itself (and the associated blood and guts), since transplantation itself is almost universally regarded as a good thing. That is, the part of the transaction that involves bodily fluids, and might inspire the kind of disgust that would keep you from contamination in other people's innards, isn't regarded as repugnant. Nor is kidney donation, which involves the surgical removal of a kidney. It's only the introduction of money into the transplant transaction that makes it repugnant. (And as we've recently seen with bone marrow, this repugnance to introducing money is alive and well, and crosses party lines.)

And I'm pretty sure there's no evolutionary disgust aroused by money (if only because money was invented pretty late in the evolutionary game...).

Pet food

Luke Stein at Stanford points me to Brian Palmer's column in Slate about where it is illegal to eat pets: Is it legal to eat your cat?

"Few states have specific laws barring the use of pets for food. The ones that do typically ban the slaughter or sale of dog and cat meat. The state of New York expressly prohibits "any person to slaughter or butcher domesticated dog (canis familiaris) or domesticated cat (felis catus or domesticus) to create food, meat or meat products for human or animal consumption." It's not clear whether the eating itself is outlawed or only the butchery. If you managed to buy dog or cat flesh from someone else who broke the anti-slaughter law, you might be OK. The law also doesn't cover ferrets, gerbils, parakeets, or other less familiar pet species. (Although the general anti-cruelty law might protect exotics.)

"California's anti-pet-eating law has a broader reach. It bars possession of the carcass, so having bought your cat steaks from someone else wouldn't be a useful alibi. The California law also protects "any animal traditionally or commonly kept as a pet or companion," rather than just Fido and Fluffy. The statute is somewhat untested, though, so no one really knows which animals are included. Pigs are not, even though they are commonly kept as pets, because they are farm animals. Horses are specifically covered by a different section of the code. There's no precedent on iguanas, goldfish, or boa constrictors.

"In most of the country, the legality of pet-eating would come down to the specific language of the general animal cruelty statute and how a judge interpreted it. Some states, such as Virginia, bar the unnecessary killing of an animal, with a specific exemption for "farming activities." In those places, it's very likely that killing a cat for dinner would get you in trouble, because the killing wouldn't be necessary, and cats aren't commonly associated with farming.
...
"Worldwide, cat and dog meat seem to be at a crossroads. China pulled dog meat off the market for the 2008 Beijing Olympics and is considering a law barring it permanently. South Korea, on the other hand, has inched toward explicitly legalizing the widespread and officially tolerated dog-meat trade."

Back in February, Roger Cohen described eating dog in China: Dog Days in China
"Now, we are appalled in the West at the notion of eating dog while considering it natural to have a dog as a pet — I own a Beagle myself (“Ned”) and I’m very fond of him. This is the inverse of the preponderant Western view of pigs: fine to eat (religious objections aside) but not to pet."

On a related matter, Abe Othman  writes about Horseflesh and Hypocrisy

"Remember, if they can come after the horse slaughterers, they can come after the hedge funds. So if you really believe in free markets, have some horse today!"

And see my earlier post: Why can't you eat horse meat in the U.S.?

This raises the question of why some people are disgusted by the idea of eating horse meat.
Michael Webster points me to the Boston Globe article "Ewwwwwwwww! The surprising moral force of disgust," which reports on a recent conference of psychologists.

"Psychologists like Haidt are leading a wave of research into the so-called moral emotions — not just disgust, but others like anger and compassion — and the role those feelings play in how we form moral codes and apply them in our daily lives. A few, like Haidt, go so far as to claim that all the world’s moral systems can best be characterized not by what their adherents believe, but what emotions they rely on.

"There is deep skepticism in parts of the psychology world about claims like these. And even within the movement there is a lively debate over how much power moral reasoning has — whether our behavior is driven by thinking and reasoning, or whether thinking and reasoning are nothing more than ornate rationalizations of what our emotions ineluctably drive us to do."

Repugnance and/or disgust

I like to distinguish what I've called repugnant transactions from those that elicit disgust. By repugnant transactions I mean transactions that some people want to engage in and that others don't want them to (e.g. same sex marriage, or buying or selling a kidney, or ordering horse meat at a U.S. restaurant). One sign that a transaction is viewed as repugnant by a sufficiently big part of the population is if it is illegal. Disgusting transactions most often don't elicit legislation (except in a consumer protection way), e.g. it's illegal in CA to offer to sell horse meat for human consumption, but not, say, spit: the difference being that some people would like to buy and eat horse meat.

However there's no denying that part of what makes some transactions repugnant to some people is that they find them disgusting (see e.g. Martha Nussbaum on same sex marriage). There have been recent reports in the press and blogosphere on attempts to link physiological indicators of disgust to, among other things, political proclivities.

Nicholas Kristof in the NY Times gives a quick overview of some conclusions of this sort: Our Politics May Be All in Our Head

Mark Liberman at Language Log takes a closer look: Physiological politics, and suggests that at least some of the results could be artifacts of the experiment. (He has a followup here: Icktheology.)

In the context of organ transplantation, I've noted that the repugnance to sales of organs is hard to equate with a visceral disgust reaction, since there isn't repugnance to transplants in general. There may of course be specific exceptions to that, see e.g. this article in the American Journal of Transplantation:
