II. Norms: The Good and the Bad

There are several different accounts of norms available in the philosophical, economic, and sociological literature. The most influential across these disciplines is the account of norms developed by Cristina Bicchieri and her collaborators.^{Footnote 3} Put simply, there is a social norm for some population if enough people in that population have a conditional preference for following the norm when they expect general conformity with that norm, both empirically and normatively.^{Footnote 4} Under these conditions, norm-following is a Nash equilibrium since no one does better by unilaterally deviating from the norm, either because they would lose from coordination failures or because they would be liable to sanction from others in the group for not complying. The key element is that my preference to conform to the norm is conditional on the belief that others have the same preferences and that others are expecting me to conform. Both of these need to be present in the case of social norms. If others expect me to conform to a norm, but my preference to conform is not dependent on whether others conform to that norm, the norm in question is what Bicchieri calls a “moral” norm. Together with “personal” norms, we can think of nonsocial norms in this sense as not conditional on the normative and empirical expectations of others.

There are several implications of this account of norms. The most important here is that there is a natural distinction between what we might think of as the positive social norms of a population and the possible norms of that population. The positive norms are those that actually exist in that population, while the possible norms are those that might exist given some change of conditional preferences or expectations. In this way, we can separate the existence of a norm from its evaluation. We can recognize that a norm requiring racial discrimination exists without thereby endorsing that norm as good. The important point is that it is possible to have genuine norms that are also, in some sense, bad. That is, we can negatively evaluate a norm without thinking that the norm is necessarily defective qua norm.

This accords with at least some of our common responses to certain norms. We find culinary norms in some other societies disgusting or bad — specifically, when other societies have norms about what kinds of animals are considered food. In the west, we keep dogs as pets and treat them like furry children. In Korea, China, and many other countries, dog meat is commonly eaten. Contrast this with Australia, where it is illegal in at least one state to eat dog meat and illegal in all other states and territories to sell it. During the Beijing Olympics, the government of the People’s Republic of China had dog meat removed from one hundred twelve “official” Olympic restaurants and they were ordered not to serve dog meat during that time.^{Footnote 5} The Chinese elites surmised that visitors would be repelled by the Chinese dog meat norms and this would reflect poorly on the country as a whole.

There are many other examples of seemingly bad norms. But, if we want to give a precise definition of what constitutes a bad norm, we need to go beyond discrete examples and develop a standard that we can use to evaluate norms more generally. This project is really composed of two subsidiary projects, one conceptual and the other evaluative. Conceptually, we need to identify the features any account of bad norms should have in order to fit the common notion or concept of a bad norm. That is, the general account of bad norms developed should intuitively fit with most of our pre-theoretical notions of a bad norm. This idea can be understood intensionally or extensionally. In principle, either understanding is acceptable, but for theoretical simplicity we can think of this idea as core extensional adequacy. The general idea of a bad norm should include the core cases of bad norms like female genital mutilation, honor killing, cannibalism, child sacrifice, and so forth. In addition, the concept of a bad norm should be operationalizable. That is, it should be constructed in such a way that we can test whether such a norm exists and fit it into our most basic social-scientific frameworks like rational choice theory. This aspect is one of the most appealing features of the general account of norms from Bicchieri with which we began this section, and is a benefit of her theory over other competitor theories.^{Footnote 6}

The third desideratum of an account of bad norms is “nonparochialism.” This is by far, the hardest feature to develop and it is importantly linked to the evaluation of norms. From any parochial point of view, we can identify and evaluate any number of alien norms as bad. If, however, we are interested in evaluating norms from a perspective that is stable across a variety of parochial points of view, we will need to establish a more robust standard. In addition to being defective as a conceptual standard, a parochial evaluative standard will also be practically defective. One of the important reasons to develop an understanding of bad norms is to change them for the better. If our evaluative standard is merely parochial moralizing, we can have little confidence that our attempts to change bad norms will be anything more than the coercive imposition of our own norms on others. This is a problem insofar as we are concerned about coercion, but also because these changes will be less likely to stick. Nonparochialism does not mean that we need an ultimate normative or evaluative standard in order to evaluate norms. This would require begging too many important questions and would require the use of a controversial theory of morality or value. Without settling any important questions about morality, we should think of nonparochialism as a standard that is accessible from any given parochial standpoint. In the case of norms, the standard requires members of the norm population to be able from their point of view to see the norm as bad. Of course, they may not regard it as bad now, but they would not need to adopt a foreign point of view in order to see the norm as bad.

As I will argue in the next two sections, to fully make sense of these features we will need to look more at the details of how to explain and evaluate norms. Before filling in the details, though, my claim is that an adequate account of bad norms will have three important features. Conceptually, any account of bad norms should be able to capture the intuitive paradigm cases of bad norms. Theoretically, a particular account should be useful in identifying actual norms within a usable social-scientific framework. The account should also be practically accessible from a nonparochial point of view. These features are identified in Table 1.

Table 1. Features of Bad Norms

The theoretical desideratum of operationalizability is realized by adopting Bicchieri’s general approach to norms. She has shown that it is operationalizable in empirical and experimental contexts. Without worrying too much about the meaning of the concept of bad norms, we can at least focus on the core cases and think of the idea of bad norms as being defined extensionally to be those cases. Nonparochialism is the hardest condition to meet, although as we saw above it is possible to weaken the condition slightly by making it more of an accessibility condition. If members of a norm group are capable of seeing that the norm is bad, then it is nonparochially bad.

In this section, I have tried to provide a thin but nevertheless useful account of what a bad norm is. We still don’t have an account of what makes the norms bad — that is, how to evaluate badness — but I have given some conditions that any account of bad norms will need to meet. To fill in those conditions, however, we will need to look more closely at how we explain and evaluate norms more generally.

III. Evaluating Norms

In this section, I look at several possibilities for evaluating norms, rejecting each one, either because of internal problems or because it fails to meet the nonparochialism condition. In the next section, I look more closely at the explanatory structure of bad norms. This will point in the direction of a different approach to evaluating norms that I will assess in Section V.

IV. Explaining Bad Norms

If we have identified some norm that we think fits the bill as a bad norm we also need to explain how the members of the norm group could both see it as a norm and potentially as a bad norm. That is, if the members of the group already mostly don’t agree with the norm or follow it, it won’t meet the basic existence conditions of a norm. Instead, we need to show that even though the norm may be bad, members have some reason to follow it as a norm. For instance, in some cultures norms of revenge and feuds are common.^{Footnote 12} These are core cases of bad norms in the conceptual sense from above. At least a critical mass of people within these societies, however, see these norms as norms, that is, as creating legitimate normative and empirical expectations. We need a method of analysis that recognizes this datum and incorporates it into the analytical and explanatory framework.

One might think that this approach is merely a descriptive or positive analysis of norms that ignores the properly normative aspects of evaluation. If this were true, it would be fatal to the project presented here since the ultimate goal is to evaluate norms, not merely to describe them. Of course, many would dispute a strong fact/value or descriptive/normative divide, but is not my goal to make any important claims on that issue here. Still, it is worth noting that this distinction is especially flexible in the case of norms. Norms are, not surprisingly, the basic material of normativity and when we are analyzing norms our task is both descriptive/positive and normative. The important point for the investigation here is that when we are dealing with genuine norms, the members of the norm group, at least, see themselves as having reason to follow these norms. Insofar as the theorist is concerned with practice and operationalizability—as I am—this cannot be ignored and the normativity of the norms for the norm population must be taken as a given. We can do this by adopting something like a Quinean or Davidsonian principle of charity when interpreting bad norms. That is, we should interpret the norm so as to construe the followers of that norm as rational. The assumption here is that all normal human agents are rational in the minimal sense of behaving in coherent, nonrandom ways. Our job is to rationally reconstruct what could be the coherent reasons why these individuals are following this particular norm and what, in turn, the norm is.

Although it is a basic assumption of most social science, this principle has some interesting properties in the present context. It means that all good explanations or analysis of norms will have a complex structure. Since it is always possible to show that someone had a reason to do something, in this case to endorse or follow a norm, on the basis of some set of beliefs about the world, we need a nontrivial way of fixing and evaluating those beliefs. To do that effectively, we need to evaluate norms on three different, though related levels. The first is the proximate level and concerns why an individual has reason to endorse or follow a norm. These explanations will be psychological or have rational choice explanations. The types of explanation in most of the economics literature have this form. We can still ask, however, why this norm and not another. And why will individuals have evolved or developed preferences to follow these norms. To answer these questions, we will need to move to the second level of evaluation, which targets the norm itself and specifically its stability properties. These ultimate explanations look at how this particular norm could have evolved and stabilized. Once we have these two parts of the explanation, we also need to understand at a third level of evaluation the details of how the norm in question works in a particular historical or cultural context. To do this we will need to look at ethnographic and historical data. This will help us know if the previous two levels of our analysis are well founded. These three levels are described in Table 2.

Table 2. Integrative Norm Analysis

So, following Mackie, the ultimate explanation of female genital mutilation in Africa is that it is a norm equilibrium that creates confidence in paternity and prevents women from being unchaste.^{Footnote 13} A sociobiological story can be told along these lines and Mackie and others have shown how this could be a stable equilibrium using plausible assumptions. Using historical and ethnographic data, we can test this hypothesis against the history of the peoples who practice female genital mutilation. We can then hypothesize about the proximate rational explanation in terms of the beliefs and preferences the men and women in the norm group must have in order to maintain the practice. This can be further checked with interviews and surveys.

At the proximate level there are several types of explanations for why particular individuals follow a particular norm. The most deflationary answer is that they prefer to follow the norm than to do otherwise. This explanation is a trivial one in one sense, but nontrivial in another. There is the question of whether individuals follow norms because they are norms; that is, do they have a preference to follow a norm or is the norm an emergent property of their preferences taken as a whole? The second is the case of classic Lewis style conventions or pure coordination problems.^{Footnote 14} In a Lewis convention, a practice is a convention not because every individual recognizes that he should follow the convention, but merely because knowing the practice allows him to coordinate effectively given that everyone else does the same. Insofar as there is a normative element in conventions, it is a tremendously weak form of rational normativity. The interesting thing, though, is that it is very difficult to find uncontroversial cases of conventions of this form. The most used example, perhaps, is driving on the left or the right, but I suspect most of us would imbue this with a stronger normative force than the conventional explanation should allow. If we were to see someone driving on the wrong side of the road we wouldn’t tend to think “look at that fool, he would coordinate better if he were only on the other side” but rather, “look at that dangerous lunatic who is on the wrong side of the road, putting us all at risk!” As someone who has recently transitioned from driving on the right to driving on the left, I can testify that the transition was not only difficult, but actually felt wrong. It seems to be very easy to load our conventional expectations with normative heft generating genuine social norms. Paul Rozin’s description of the process of moralization may shed some light on this phenomenon.^{Footnote 15} We may also want to look to Haidt’s social intuitionist model of moral judgment.^{Footnote 16} According to Haidt, our judgments are pre-loaded and are heavily affect laden. When we give reasons for our judgments we do so to convince others, not to justify those conclusions to ourselves. Since normative expectations and evaluations are some of the most powerful weapons in our persuasive and justificatory arsenal, it is perhaps no surprise that we are quick to deploy them. What is more surprising is that we should be so susceptible to their charms.

Sometimes this normative projection can cause problems, however. One example is in the case of pluralistic ignorance. This kind of situation creates what Bicchieri calls a “collective illusion” about a norm and, as she notes, norms based on collective illusions can be “fragile.”^{Footnote 17} Once the illusion is undermined, there can be a cascade away from the norm. One strong hypothesis about why people follow norms that seem obviously “bad” like FGM is that there is widespread pluralistic ignorance. As Mackie is careful to point out, almost all of the people who practice FGM claim to love and want what is best for their daughters.^{Footnote 18} They believe everyone else in their group wants the same. The problem is that they have false beliefs about how much other people are committed to the norm. In reality, so this explanation goes, most people are opposed to the norm and only follow it because they wrongly believe that others are committed to it. Although there is some reason to think that this original explanation was too simple, Bicchieri takes the idea further and introduces a variable K that acts as a weight on how much the norm in question factors into an individual’s utility function.^{Footnote 19}

The pluralistic ignorance explanation is charitable since it assumes that individuals in a norm group are rational and it seeks to formally characterize their utility functions. It does, however, assume that those individuals are under an illusion and that the norm will evaporate once this illusion is punctured. Another explanation is that, given the alternative available, the norm in question is the best available or, at least, that there is no better norm available. If this is a possibility in a large number of bad norms cases, as I will argue that it is, then pluralistic ignorance is a special not general proximate explanation. The implication is troubling since changing bad norms will be more difficult than undermining an existing illusion. This will lead us away from proximate analysis on its own and toward linking proximate and ultimate analysis with an evaluative standard. I turn to that in the next section.

V. Comparative-Functional Analysis

The main problem with the welfare approaches is that they attempt to present a global standard to evaluate norms. As we saw, these approaches had several serious problems, as do all other methods of attempting to provide a global evaluative standard for norms. In addition, we saw in the last section that understanding norms requires different kinds of analysis at several different levels. Most analysis is concerned only with proximate or historical/cultural evaluation. In this section, I will argue that we need to incorporate more of the ultimate analysis in order to evaluate norms and I show how this can be done in the case of honor norms.

To move beyond the evaluative standards we saw in Section III, we need to expand the information base we use to evaluate norms. The efficiency and welfare approaches only look at outcomes and ignore the process by which norms generate these outcomes. This may seem harmless since we are ultimately concerned about the welfare effects of these norms, but it makes our evaluation of these norms more difficult as well. In this section, I will argue that we need to look at the functional role that norms play in particular contexts to be able to coherently evaluate them. Once we see what roles these norms play, we can attempt to evaluate whether there are alternative norms that can also play that role as well or better than the norm in question. If so, we can then evaluate what the benefits and costs of shifting to a new norm will be along various dimensions. In some cases, the new norm will dominate the old norm on all the relevant dimensions and in those cases this alternative norm will be preferable to everyone. This is not the typical case, but whatever the different costs and benefits, this form of evaluation will make it clear to those participating in the norm how expensive the norm is in terms of the opportunity costs of switching to a new norm.

Put simply, this comparative-functional approach to evaluating norms solves some of the problems that we have seen with other ways of evaluating norms. First, it avoids the Pareto problem by not attempting to make a global evaluation and thereby avoiding the problem of fixing the context of comparison. The Pareto standard requires a fixed standard for evaluation in order to determine whether something is a Pareto improvement or not. This parameter is free in a global standard, making Pareto evaluations of norms either trivial or impossible. On the local functional approach, however, we can fix the Pareto baseline at the status quo and evaluate the norm in question with respect to a fixed neighborhood of other possible norms. So, rather than evaluating a given norm against all other possible norms, we evaluate a specific norm against a set of feasible alternatives. What determines the feasible alternatives is not always clear, and it will be necessary to look at the functional role of the norm in question to help populate that set.

We should not confuse the idea of a “functional role” with traditional “functionalist” social theory. Functionalism as a general approach to social theory has rightly been discredited.^{Footnote 20} Instead, the “functional” aspect of comparative-functional analysis should be understood as a kind of as-if analysis that mirrors, at the ultimate level of analysis, the assumption of charity at the proximate level of analysis.^{Footnote 21} That is, we assume that if a norm exists, it represents a stable equilibrium of social interaction. This alone, however, tells us very little. We need to know more about the kind of interaction for which this norm represents an equilibrium in order to understand the norm. As Bicchieri argues, norms often represent equilibria that are only possible once they have been implemented and, thereby, have changed the initial base game. To identify the social “functional role” of a norm, then, is to identify what game this norm acts as an equilibrium for. Only once we know that can we effectively compare the norm in question to other norms that might also be equilibria to that game or to think of ways of changing the game with additional or different norms.^{Footnote 22} Obviously, then, comparative-functional analysis is not a rejection of methodological individualism. Indeed, the integrative approach explained above and comparative-functional analysis only make sense from an individualist point of view. Any “functional role,” since it is an equilibrium in a game, must be ultimately reducible to the proximate preferences, beliefs, and values of the individuals in the norm group. Still, comparative-functional analysis goes beyond traditional rational choice theory in unifying the ultimate level of analysis (“as-if” functional role) with the proximate level (the rational decision making of individual choosers). Doing so allows us to determine the set of feasible norm alternatives.

Once this set is populated, we can compare a specific norm R ₁ against members of R* and ask whether the move from R ₁ to each element of R* would be a Pareto improvement. The members of R* that would be judged a Pareto improvement for the set M, the maximal set of R* where $M \subseteq R{\rm{*}}$ and M (R*, ≽) = [x|x ∈ R* & for no y ∈ R* : y ≻ x].^{Footnote 23} That is, the maximal set is composed of all the elements where there is no element that strictly dominates another. Put simply, M defines the Pareto frontier of feasible, efficient alternatives. The alternatives in the maximal set, by definition, do not Pareto dominate one another and so, from the point of view of Pareto analysis, this is the end of the story. But there is clearly more we can say about each alternative. It might be that some alternatives are comparatively better for some members of the population or that some alternatives seem like particularly good or bad matches for a given population. Comparing those alternatives to one another and to the status quo norm, we can generate the relative price of the alternatives in terms of the opportunity cost of moving to one norm rather than another. Different members of the population will view this price differently. Some will see the status quo as very expensive while others will see particular alternatives as expensive.

There is an additional question about whether each norm has one and only one functional role or, to put it another way, whether there is a principled way of individuating norms and functions.^{Footnote 24} In one sense, there will always be a certain indeterminacy in the individuation of norms in the same way that there is a fundamental problem of individuating states and actions in decision theory. Or rather, the problem is in providing a unique individuation of norms and, for that matter, functions. To ask whether there is only one function for each norm is really to ask two questions then: First, can norms and functions be uniquely individuated? And second, is there a function that relates each function to each norm? I am not confident that either of these questions can be answered in a nontrivial way that is externally valid. Both individuation and the relationship between norms and functions proceed from the goals of the researcher. This is to say that the practice of investigation will fix the answer to these questions as work continues on these problems. By following the integrative approach, feedback between the local level of norm participants and models will contribute to making the individuation and relationship between norms and functions more and more externally valid over time.

Following the tradition in social choice and bargaining theory, we might see the goal at this point as developing a mechanism with certain properties (strategy-proof, incentive compatibility, and so on) for negotiating these prices and determining a unique solution to which norm should be chosen. This would be a mistake in the case of norms, however. Norms do not arise from a process of collective choice and it would be misleading to think of the process of norm evaluation and change as similar to collective choice rather than social evolution.^{Footnote 25}

This approach has the potential to avoid parochialism because it requires us to look at the norm both from the ultimate point of view and the point of view of those within the norm group. Evaluating a norm from either point of view separately would miss something important, either the function of the norm or the reasons individuals have for following it. Evaluating feasible alternatives and weighing their relative costs also requires us to take the point of view of those within the norm group. All of this should act as a check on parochialism. Further, since this approach basically adopts a Bicchieri norm analysis at the proximate level it should be operationalizable and testable in the same ways. Conceptually, we use our already existing notions of bad norms to identify potential candidates to test, so it should meet that desideratum as well. It looks like the comparative-functional account can meet all of the desiderata set out in Section I.

Used as a method for analyzing and evaluating norms, the comparative-functional approach can be understood as a high-level algorithm or as a series of questions:

1. 1. What is the norm?

2. 2. What social functional role does this norm play?

3. 3. What is the historical/institutional/cultural context of the norm?

4. 4. What are the reasons that individuals comply with and expect others to comply with the norm?

5. 5. Are there other feasible norms that:

   1. a. would perform the same or similar functional role?

   2. b. are compatible with the context?

   3. c. could be supported by similar reasons?

6. 6. What are the relative costs and benefits of moving to one of these norms for those in the norm group?

Answering all of these questions will be difficult and require attacking the problem from all three levels of analysis described in the last section.

To see how this works in detail, it is worth looking at a concrete example of this comparative functional analysis in action. My colleague Toby Handfield and I have developed a comparative-functional analysis of violent honor norms, what we call honor-based violence.^{Footnote 26} Feuds, vendettas, and duels undertaken to defend one’s honor or to repair some slight to honor are classic examples. Another form of honor-based violence is the honor killings of women who have violated or are believed to have violated community sexual norms. We argue that in societies with weak governance institutions, norms of honor-based violence can help to solve two types recurrent problems: deterrence and assurance. We divide the honor norms dealing with each problem into what we call revenge and purification honor norms.

Revenge honor norms serve to address one of the oldest problems of politics: how to emerge from a Hobbesian state of nature, where “there is no place for Industry; because the fruit thereof is uncertain,” to a society in which property rights are sufficiently secure that economic activity can thrive.^{Footnote 27} This problem—the deterrence problem—is the problem of establishing a credible threat that violations of one’s self or property will be met with violence in virtually all circumstances, regardless of the strength of the attacker. Or, more precisely, it is the problem of ensuring that threats are not evaluated by weighing the costs and benefits of response at a particular time, on a case-by-case basis. Credible deterrence is a combination of two features. First, one must be able to signal strength. Second, one must be able to signal that one (or the collective of which one is a part) can be counted on to carry out retaliation, even when this is not strictly rational. Attacks or trespasses will be resisted even when the costs of doing so will outweigh the benefits.

The second type of honor norm, which we call purification honor norms, relate to assurance. The practice of “honor killings” and similar phenomena emerge from this category. Honor killings occur when, typically, male members in a family kill one of their female relatives because she has violated norms of sexual impropriety. In their eyes, she has “dishonored” the family with her behavior and they believe that the only way the resulting debt of honor can be paid is with her life. For instance, in October of 2009, Faleh Hassan Almaleki killed his daughter Noor Almaleki by running her down with his Jeep in a Phoenix, Arizona parking lot. Noor, who was twenty years old, had defied her father by walking away from an arranged marriage with a cousin in Iraq and by living with her boyfriend against her father’s wishes. She had, according to her father, become “too westernized.”^{Footnote 28} In that Phoenix parking lot, Faleh revved his engine and accelerated directly into his daughter, dragging her for twenty feet behind the Jeep.

Ten years earlier, in 1999, a nineteen-year-old Kurdish Swede named Pela Atroshi was executed at close range by a gunshot to her head.^{Footnote 29} The killer was one of her uncles who, along with a group of his other male relatives, and motivated by the belief that Pela failed to adhere to traditional Kurdish principles of sexual morality for women, plotted and carried out the murder of his niece. Two of these men, the patriarch Abdulmajid Atroshi and one of the accomplices, were living in Australia at the time. They lured Pela back to Kurdish lands in Northern Iraq where they assumed—correctly—that the honor killing would be punished lightly. Three of the murderers were convicted. They were sentenced with a one-year, suspended sentence. The court cited the “defendants’ honourable motivation” as a reason to excuse their offense. In societies that practice honor killing, there is a strong preoccupation with a woman’s sexual behavior. Women are frequently confined, veiled, and deprived of opportunities to work or study. A superior equilibrium is available, in which these costly practices are not regarded as prerequisites for marriage; but because any family that deviates from the conventions is likely to suffer immediate costs in the marriage market, it is difficult to shift. Another example of norms that seem to have the same function concerns the norms that govern violent gangs in American prisons.^{Footnote 30} In prisons, there is no recourse to external governance mechanisms to deter violence and the prisoners must organize themselves into protective associations to provide that function.

In the case of honor killing, the norm is that the male family members in a culture with this norm must kill a female family member who has been (or is thought to have been) unchaste. The social function the norm performs, we argue, is to guarantee purity and assurance between families in heavily asymmetric and long time-frame exchanges. The historical/institutional/cultural context of the norm varies from society to society, but there are important similarities in family structure and unreliability of paternity. Individuals comply with the norm because they see it as reflecting on the “honor” or value of their family and see the sister or daughter as undermining the reliability or trustworthiness of the family.^{Footnote 31}

Are there other feasible norms in this case? That question is difficult to answer. In one sense the answer is obviously “yes.” Marriages occur in parts of India, Pakistan, and other parts of the world without resorting to honor killing, so we know that there is a feasible alternative because there is an actual alternative.^{Footnote 32} The relevant question, though, is whether the people in the norm group would see this option as feasible. Presumably, numerous members of the norm group know that this is not how women are treated in many other parts of the world and yet still engage in this practice. We hypothesize that stronger, civil marriage law, a more open marriage market, and reliable paternity information could help make alternative norms seem less costly. More work still needs to be done on this issue, however, since there are a number of remaining unknowns about the properties of this signaling equilibrium, even if our analysis is correct.
