Social science and policy

One of the important reasons that we value scientific knowledge is the possibility that it will allow us to intervene in the world to solve problems that we care about. Good climate science allows us to have high confidence in the causes of global climate change; and it also provides a sound basis for policy interventions to help to mitigate the pace of climate change. Good cellular biology permits a better understanding of autoimmune disease; and it also suggests avenues for prevention and treatment. There is thus an important component of pragmatism in our esteem for scientific knowledge.

In the social sciences we would like to assume that something similar is possible. If we have good sociological understanding of the causes of teen pregnancy or gang violence, perhaps that understanding will also provide a basis for designing effective interventions that reduce the incidence of the social problems we study. In other words, perhaps we can count on social science to provide a valuable and effective basis for the design of social policy.

The philosophy of social science that I've developed in this blog and in New Directions in the Philosophy of Social Science raises some challenges to that hope. It is argued here that the social world is contingent, heterogeneous, plastic, and conjunctural. In the words of Roy Bhaskar, social causation takes place in an open system in which we cannot arrive at confident predictions of particular social outcomes. In place of general theories and comprehensive social laws, it is argued here that we are best advised to seek out particular causal mechanisms that underlie various social outcomes of interest. And it is emphasized that it is difficult to make predictions in particular circumstances even when we have an idea of some of the operative social mechanisms, because of the perennial possibility of contingent interventions by additional factors.

So the hard question is this: to what extent is it at all possible for social science research to provide a confident basis for the design and implementation of social policies to address important social problems?

One approach that does not seem promising is the methodology of random controlled trials (RCT). The logical shortcomings of this approach when applied to social phenomena have been highlighted by Nancy Cartwright and Jeremy Hardie in Evidence-Based Policy: A Practical Guide to Doing It Better, and I discuss these problems In an earlier post (link). So it does not seem promising to expect that we will be able to isolate causal mechanisms (for example, "provide after-school tutoring") and use the method of RCT to demonstrate the efficacy of this mechanism in reducing a given social harm (say, "high school absenteeism").

The problem of establishing a strong relationship between theory and policy has been considered in several areas of social research. One such study is in the field of international relations. Stephen Walt's 2005 article, "The relationship between theory and policy in international relations", is an extended treatment of the topic (link). Here is the abstract to Walt's paper:

Policy makers pay relatively little attention to the vast theoretical literature in IR, and many scholars seem uninterested in doing policy-relevant work. These tendencies are unfortunate because theory is an essential tool of statecraft. Many policy debates ultimately rest on competing theoretical visions, and relying on a false or flawed theory can lead to major foreign policy disasters. Theory remains essential for diagnosing events, explaining their causes, prescribing responses, and evaluating the impact of different policies. Unfortunately, the norms and incentives that currently dominate academia discourage many scholars from doing useful theoretical work in IR. The gap between theory and policy can be narrowed only if the academic community begins to place greater value on policy-relevant theoretical work.

Fundamentally the article raises the question of whether there is a useful relationship between international relations theories and the practice of diplomacy and foreign policy. Can IR theory guide the construction of a successful foreign policy?

Here are some of the ways that Walt believes theory can be used to support policy analysis. Walt believes that theory can assist policy analysis in four important ways, including diagnosis, prediction, prescription, and evaluation. Unfortunately, none of the examples that he offers provide much confidence in any of these capabilities in a significant way. Diagnosis comes down to classification; but given that the idea of a social kind is suspect, we do not add much to our knowledge by classifying a given regime as "fascist", because we know that there is substantial variation across the group of fascist states. Prediction (as Gandhi said about Western civilization) would be nice; but it is almost never attainable in real social situations. Prescription requires a sound knowledge of the likely causal dynamics of a situation; but the open nature of social reality implies that we cannot have such knowledge in any comprehensive way. And evaluation is subject to similar issues. Walt assumes we can evaluate the success of a policy in a quasi-experimental way -- observe the cases where the intervention took place and measure the frequency of the desired outcome. But unfortunately this quasi-experimental method is also suspect.

An important drawback of Walt's treatment is the fairly traditional view that Walt takes with regard to the content of scientific knowledge. There is an underlying preposition of a fairly Humean view of cause and effect.

Policy makers can also rely on empirical laws. An empirical law is an observed correspondence between two or more phenomena that systematic inquiry has shown to be reliable. (25)

But in fact, there are very few useful "empirical laws" in the social realm that might serve as a basis for simple cause-and-effect policy design.

At present, then, there is a still a significant gap between an empirically supported social theory and a well designed social intervention. Unfortunately social causation is rarely as simple and regular as the empiricist framework presupposes. This is indeed disappointing, because it is certainly true that we most urgently need guidance in designing strategies for solving important social problems. (Here is an earlier post that offers a somewhat more positive assessment of the relevance of theory to policy; link.)

Small farmers in Indian agriculture

Agriculture remains the primary source of income for India's population, and the majority of India's farmers subsist on small farms, less than two hectares (five acres). It is all but self evident that these facts imply continuing poverty and low quality of life for rural Indians. And yet the basic facts and economics of the small farm sector are poorly understood. 

The most recent product of the Project on Agrarian Relations in India (PARI) focuses on exactly this question (link). Madhura Swaminathan and Sandipan Baksi's recent volume, How Do Small Farmers Fare?: Evidence from Village Studies in India, attempts to provide a multidimensional appraisal of the complex realities of the small farm economy in India, including labor, crop productivity, incomes, costs, fertilizer use, credit, climate change, education, living standards, and an overall assessment of how small farmers fare. The book draws upon largescale statistical data collected by the Indian government, but the fundamental insights offered in each chapter are drawn from the intensive village studies conducted by PARI researchers over the past dozen years (link). And, as the resolution and quality of the essays in this volume attest, the PARI village studies constitute an enormously valuable source of information on the rural economy in India in spite of the small number of villages included.

T. Sivamurugan and Madhura Swaminathan provide an excellent survey of the methodology and scope of the PARI project in their chapter on this subject. Their chapter provides detailed information about the methodology pursued in designing and carrying out these village studies in a range of regions in the country.

The Project on Agrarian Relations in India (PARI) began in 2006. One of the objectives of the Project is to analyse village-level production, production systems and livelihoods, and the socio-economic characteristics of different strata of the rural population. As of 2016, 25 villages from 11 States of the country, covering a wide range of agro-ecological regions in the country, have been studied under PARI. In this volume, we have used data on 17 villages from 9 States. (25)

It is apparent that the PARI project considers only a small percentage of India’s villages and farming regions. However, the locations chosen have been selected to provide a useful indication of the economic status of villages and farm households in a variety of locations.

The summary data provided by this research are striking: 

According to the Agricultural Census of 2010–11, there were a total of 138.35 million operational holdings in India. The total area operated was 159.59 million hectares and the average size of an operational holding was 1.15 hectares. The average size of all holdings of size 2 hectares or less – which constituted small and marginal holdings as per the official definition – was 0.60 hectare. Holdings of size 2 hectares or less accounted for around 85 per cent of all holdings and 45 per cent of the total area operated. The number of persons who were part of small farmer households was close to half a billion. (2)

Almost 50% of India's total population consists of small farmers and their families, and 85% of all farms are less than two hectares. Plainly the situation of small farms is of enormous importance to the overall social wellbeing of India.

A particularly important topic in this volume is the assessment of small farmers' incomes that the studies permit. The summary conclusion is that India's hundreds of millions of small farmers earn incomes only slightly higher than subsistence. Rural manual workers earn even lower income.

The levels of income received by small farmer households were low, in both absolute and relative terms. The average incomes received by small farmers were not much higher than the minimum wages in agriculture stipulated by State governments. Minimum wage in India is defined as subsistence wage; hence incomes received by small farmer households were inadequate to meet investments or any requirements other than daily consumption needs. (162)

An important measure of quality of life of poor people is number of years of schooling. The PARI studies show that children in small farmer households have extremely low levels of schooling, and that there are significant difference between boys and girls. Chapter 11 finds similar evidence of deprivation with regard to other material features of quality of life: access to clean drinking water, toilets, electricity, and living space and housing.

Moreover, the studies demonstrate that these kinds of deprivation are further exacerbated by facts of caste and religion.

While small farmer households are the worst off among the peasantry, there exist disparities and differences within the class of small farmers on the basis of social identity. The analysis presented in this chapter shows that SC, ST, and Muslim households among small farmers are far more deprived in terms of housing and access to basic household amenities than households belonging to other social groups. This points to the fact that in Indian society, and more so in rural society, deprivation is not merely economic but social as well. Even though a uniform criterion was used to define small farmer households, we find that higher levels of deprivation among SC, ST, and Muslim households are an outcome of the historical exclusion and accumulated disadvantages faced and inherited by these social groups. Continued practices of untouchability, physical and residential segregation, and isolation shape current outcomes for these groups. (327)

It has sometimes been maintained that small farming is potentially as productive as largescale commercial farming. It is maintained that intensive family labor has the potential for producing crops as efficiently as mechanized capital intensive farming -- presumably because of the lack of efficiencies of scale in farming. The research reported here by Venkatesh Athreya and colleagues rebuts this longstanding assumption about small-scale farming:

At the core of the argument in favour of small-scale farming in terms of its efficiency is the alleged inverse relationship between land productivity and size. It states that small farms are more efficient, de ned in terms of yield per acre, than large farms. It is argued that this relationship holds true more or less universally. This assertion was also the basis of the debate in India on farm size and productivity based on findings from the Farm Management Studies. This argument, which continued through the 1960s, has seen a recent revival. Apart from the empirical challenge posed to this formulation (especially by the green revolution), it has also been theoretically rebutted by Terence Byres…. The body of empirical evidence from FAS surveys too does not support the hypothesis of an inverse relationship between farm size and output per unit of land.

One thing that is noteworthy in this collection is the significant use that the authors make of classical Marxist analysis of agricultural development and the peasantry. Unlike other national traditions in the social sciences, Indian researchers continue to find insights and valuable frameworks in the writings of Marx, Lenin, Kautsky, and other Marxist writers on these topics. And, as the many texts cited in the introductory chapter illustrate, these figures were in fact careful observers of the agrarian systems of Europe. Here is how Athreya et al summarize the Marxist perspective in the Indian context:

The attitude towards the peasantry in the context of India’s development, especially after the country won political independence, has been a matter of much discussion in Indian Marxist literature. Comprehensive land reform is essential to the completion of the democratic revolution in India. Achievement of the democratic revolution under a working class leadership in alliance with the peasantry, especially poor peasants and agricultural labourers as key rural classes in this process, is necessary for further democratic advance. Such a view envisages the continued presence of a large population of small and middle peasants for a long time. We need public policy that supports the peasantry, especially focusing on developing the productive forces among them. (14)

This volume is a very important contribution to development studies in India and other parts of South and Southeast Asia. The dynamics of agriculture remain a critical factor in the social progress of these countries, and this careful and detailed research will provide a basis for constructing more effective development policies in India and elsewhere. And the data suggest that the situation of the rural sector in India is in crisis: incomes for small farmers and landless workers are extremely low with few indications of improvement, and measures of quality of life mirror these findings.

How to think about social identities

What is involved in having a national or racial or sexual identity? What do we mean when we say that a person has a Canadian or a Haitian identity? How can we best think about the mental frameworks and models that serve as lenses through which people understand themselves and their places in history?

Most basically, an identity is a set of beliefs and stories about one's home and one's people. These ideas often involve answers to questions like these: Who am I? What groups do I belong to? How did my group get to the current situation? Where did we come from? And perhaps, who are my enemies? So an identity often involves a narrative, a creation story, or perhaps a remembrance of a long chain of disasters and crimes. Identity and collective memory are intertwined; monuments, icons, and flags help to set the way points in the history of a people and the collective emotions that this group experiences.

Identities are interwoven with narratives and folk histories. They have to do with the stories we tell each other about who we are; how our histories brought us to this place; and what large events shaped us as a "people". And, as Benedict Anderson so eloquently demonstrated in Imagined Communities: Reflections on the Origin and Spread of Nationalism, these stories are more often than not fictions of various kinds, promulgated by individuals and groups who have an interest in shaping collective consciousness in one way or another.

Identities are also often closely linked with performances of various kinds -- holidays, commemorations, funerals and weddings, marches and demonstrations. It is not surprising that historians like Michael Kammen (Mystic Chords of Memory: The Transformation of Tradition in American Culture) give great attention to monuments and celebrations; these are the tangible items that contribute to the formation of an identity as an American, a Black Panther, a Serb, or a Holocaust survivor.

There is an interesting corollary question: are there requirements of consistency that appear to govern the contents of a national or racial identity? If a person's identity involves adherence to the idea of gender equality, does this imply that the person will also value racial equality? If a person values loyalty to his friends, will he or she also be likely to value promise-keeping or truth-telling to strangers?

We might expect consistency among the elements of an identity if we assumed that individuals are reflective agents, weighing and comparing the various components of their identity against each other. This kind of mental process might be expected to lead individuals to notice a similarity between "equality between men and women" and "equality between Christians and Muslims", and might adjust his bigoted beliefs about Muslims in order to make them more compatible with his beliefs about gender equality. If, on the other hand, we think of individuals as unreflective and dogmatic, then there may be less ground for expecting a gradual adjustment of beliefs into a more consistent whole. On that scenario, the components of a person's identity are more similar to the likes and aversions of the palate than the considered judgments of morality.

Finally, it is also clear -- as the theorists of intersectionality have demonstrated (for example, Patricia Hill Collins; link) -- that most of us possess multiple identities at the same time. We are Irish, European, lesbian, working class, anti-fascist, and Green, all at the same time. And the imperatives of the several identities we wear are often different in the political actions that they call for. Here again the question of consistency arises: how are we to reconcile these different calls to action? Is there an underlying consistency of values, or are the orienting values of one's anti-fascism largely independent from one's commitments to a pro-environmentalist agenda?

It is clear that various kinds of identities are highly relevant to politics and collective action. Appeals to identity solidarities have powerful effects on mobilization and political activization. But given that identities are not primeval, it is also clear that identities are themselves the subject of political struggle. Leaders, activists, and organizations have powerful interests in shaping the content and focus of the identities that are realized in the groups and individuals around them.

Intergenerational social mobility

A crucial part of social cohesion is the prospect of social mobility across generations. A social order in which individuals are stuck in their social position as a result of the lack of social assets of their parents is one which lacks legitimacy for an important part of its population. (Here are a few earlier posts on social mobility in the United States; link, link.) This observation raises several crucial questions. How do we measure social mobility? What obstacles stand in the way of social mobility for some segments of a given population? And what mechanisms exist to increase the pace of social mobility for a given society?

Raj Chetty and his colleagues have profoundly changed the terrain for social scientists interested in these questions through a striking new approach. Their work is presented on the Equality of Mobility website (link). The map above shows that there are very sizable regional differences in social mobility rates, from the deep south to the plains states and upper midwest.

Of particular interest is the light their research sheds on the role that post-secondary education plays in social mobility. A summary of their findings is presented in an NBER research paper, "Mobility Report Cards: The Role of Colleges in Intergenerational Mobility" (link). Here is a statement of their approach:

We take a step toward answering these questions by using administrative data covering all college students from 1999-2013 to construct publicly available mobility report cards – statistics on students’ earnings outcomes and their parents’ incomes – for each college in America.1 We use de-identified data from federal income tax returns and the Department of Education to obtain information on college attendance, students’ earnings in their early thirties, and their parents’ household incomes.2 In our baseline analysis, we focus on children born between 1980 and 1982 – the oldest children whom we can reliably link to parents – and assign children to colleges based on the college they attend most between the ages of 19 and 22. We then show that our results are robust to a range of alternative specifications, such as measuring children’s incomes at the household instead of individual level, using alternative definitions of college attendance, and adjusting for differences in local costs of living.

Their research involves linking federal tax returns for two generations of individuals in order to establish the relationship between the parents' income group and the child's income group after college. (The tax data are de-identified so that the privacy of the individuals is protected.) The Equality of Mobility website includes downloadable datasets for the report cards for several thousand post-secondary institutions.

A highlight of this analysis is the very substantial impact on social mobility created by regional public universities.

The colleges that have the highest bottom-to-top-quintile mobility rates – i.e., those that offer both high success rates and low-income access – are typically mid-tier public institutions. For instance, many campuses of the City University of New York (CUNY), certain California State colleges, and several campuses in the University of Texas system have mobility rates above 6%. Certain community colleges, such as Glendale Community College in Los Angeles, also have very high mobility rates; however, a number of other community colleges have very low mobility rates because they have low success rates. Elite private (Ivy-Plus) colleges have an average mobility rate of 2.2%, slightly above the national median: these colleges have the best outcomes but, as discussed above, also have very few students from low-income families. Flagship public institutions have fairly low mobility rates on average (1.7%), as many of them have relatively low rates of access. Mobility rates are not strongly correlated with differences in the distribution of college majors, endowments, instructional expenditures, or other institutional characteristics. This is because the characteristics that correlate positively with children’s earnings outcomes (e.g., selectivity or expenditures) correlate negatively with access, leading to little or no correlation with mobility rates. The lack of observable predictors of mobility rates underscores the value of directly examining students’ earnings outcomes by college as we do here, but leaves the question of understanding the production and selection technologies used by high-mobility-rate colleges open for future work. (3-4)

These are by and large the institutions that constitute the membership of the American Association of State Colleges and Universities (link). AASCU institutions are distinguished by the commitment that they commonly share to enhancing access for under-serviced members of society, and to contributing to social mobility in the regions and states that they serve. These values are expressed in the American Democracy Project (link). The evidence of the Chetty project appears to validate the achievement of that mission.

There are additional questions that one would like to be able to answer using the kinds of data that Chetty and his colleagues have considered. Central among these have to do with other measures of social mobility. The definition of social mobility in use here is transition from the bottom quintile of income to the top quintile of income in one generation. But it would be illuminating to consider less dramatic social movement as well -- for example, from the bottom quintile to the middle quintile. It is also interesting to consider whether the variable measuring the likelihood of the child achieving the first quintile of income given parents in the bottom quintile might not be an alternative measure of the social-mobility efficacy of a given institution. This differs from their definition in that it is not weighted by the percentage of students from the lowest quintile.

This research underlines the critical importance of public higher education in the United States. We need to do a better job of supporting public universities so that the cost of higher education is not so heavily skewed towards tuition revenues. The benefits of public universities are certainly of value to the individual graduates and their families. But the increased social mobility enabled by many public universities also enhances democratic legitimacy at a time when many institutions are under attack.

Social consciousness and critical realism

Critical realism proposes an approach to the social world that pays particular attention to objective and material features of the social realm -- property relations, impersonal institutional arrangements, supra-individual social structures. Between structure and agent, CR seems most often to lean towards structures rather than consciously feeling and thinking agents. And so one might doubt whether CR has anything useful to offer when it comes to studying the subjective side of social life.

Take for example the idea of a social identity. A social identity seems inherently subjective. It is the bundle of ideas and frameworks through which one places himself or herself in the social world, the framework through which a person conceptualizes his/her relations with others, and an ensemble of the motivations and commitments that lead to important forms of social and political action. All of this sounds subjective in the technical sense -- a part of the subjective and personal experience of a single individual. It is part of consciousness, not the material world.

So it is reasonable to ask whether there is anything in a social identity that is available for investigation through the lens of critical realism.

The answer, however, seems to be fairly clear. Ideas and mental frameworks have social antecedents and causal influences. Individuals take shape through concrete social development that is conducted through stable social arrangements and institutions. Consciousness has material foundations. And therefore, it is perfectly appropriate to pursue a realist materialist investigation of social consciousness. This was in fact one important focus of the Annales school of historiography.

This is particularly evident in the example of a social identity. No one is born with a Presbyterian or a Sufi religious identity. Instead, children, adolescents, and young adults acquire their religious and moral ideas through interaction with other individuals, and many of those interactions are determined by enduring social structures and institutional arrangements. So it is a valid subject of research to attempt to uncover the pathways of interaction and influence through which individuals come to have the ideas and values they currently have. This is a perfectly objective topic for social research.

But equally, the particular configuration of beliefs and values possessed by a given individual and a community of individuals is an objective fact as well, and it is amenable to empirical investigation. The research currently being done on the subcultures of right wing extremism illustrates this point precisely. It is an interesting and important fact to uncover (if it is a fact) that the ideologies and symbols of hate that seem to motivate right wing youth are commonly associated with patriarchal views of gender as well.

So ideas and identities are objective in at least two senses, and are therefore amenable to treatment from a realist perspective. They have objective social determinants that can be rigorously investigated; and they have a particular grammar and semiotics that need to be rigorously investigated as well. Both kinds of inquiry are amenable to realist interpretation: we can be realist about the mechanisms through which a given body of social beliefs and values are promulgated through a population, and we can be realist about the particular content of those belief systems themselves.

Ironically, this position seems to converge in an unexpected way with two streams of classical social theory. This approach to social consciousness resonates with some of the holistic ideas that Durkheim brought to his interpretation of religion and morality. But likewise it brings to mind Marx's views of the determinants of social consciousness through objective material circumstances. We don't generally think of Marx and Durkheim as having much in common. But on the topic of the material reality of ideas and their origins in material features of social life, they seem to agree.

These considerations seem to lead to a strong conclusion: critical realism can be as insightful in its treatment of objective social structures as it is in study of "subjective" features of social consciousness and identities.

Community resilience

We know what is meant by saying that a physical system is resilient: for a given range of shocks, the system has the ability to recover its structural integrity. This does not mean that a resilient system is impervious to shocks, but rather that it is capable of recovery from a given range of shocks at a given level of severity (through redundancy, decentralized systems, or repair mechanisms). (Here is a discussion of urban resilience and fragility in face of natural disaster by Kathleen Tierney in The Social Roots of Risk: Producing Disasters, Promoting Resilience; link.)

We also think we know something about individual resilience. It is a complex capacity of personality and character that permits the individual to regain equanimity after some of life's common hazards -- loss of a job, onset of a serious illness, death of a loved one. Here is how the American Psychological Association defines resilience (link):

Resilience is the process of adapting well in the face of adversity, trauma, tragedy, threats or significant sources of stress — such as family and relationship problems, serious health problems or workplace and financial stressors. It means "bouncing back" from difficult experiences. 

Research has shown that resilience is ordinary, not extraordinary. People commonly demonstrate resilience. One example is the response of many Americans to the September 11, 2001 terrorist attacks and individuals' efforts to rebuild their lives. 

Being resilient does not mean that a person doesn't experience difficulty or distress. Emotional pain and sadness are common in people who have suffered major adversity or trauma in their lives. In fact, the road to resilience is likely to involve considerable emotional distress. 

Resilience is not a trait that people either have or do not have. It involves behaviors, thoughts and actions that can be learned and developed in anyone.

How does the idea of resilience work in application to communities -- in particular, multi-ethnic, multi-racial, and multi-religious communities? Shocks occur in all communities -- a violent crime is committed, a fiery speech is issued, a labor crisis occurs, a harvest fails. All of these incidents have the capacity to initiate a cycle of inter-group recrimination and separation. What features of community life and organization permit a multi-group community to regain its stability and inter-group harmony? What features exist that can stop the slide into escalation and eventual antagonism and violence across groups?

Historical experience in many parts of the world shows that communities of mixed populations sometimes degenerate into antagonism and violence across groups. The histories of ethnic and religious violence in India and the current tragedy of the Rohingya in Myanmar provide clear examples. Mixed communities that have lived peacefully and harmoniously are suddenly riven by mistrust, antagonism, and hate that lead to inter-group violence. (An earlier post dissected some of the pathways through which this process takes place; link.)

Here is how Paul Brass describes the emergence of violent collective action in India in The Production of Hindu-Muslim Violence in Contemporary India.

Most commonly, the rhetoric is laced with words that encourage its members not to put up any longer with the attacks of the other but to retaliate against their aggression. There are also specific forms of action that are designed to provoke the other community into aggressive action, which is then met with a stronger retaliatory response. (24)

Here Brass describes a dynamic process of provocation, escalation, and inter-group competition that leads quickly to antagonism and violence. And, as he makes clear throughout his book, this process is often stimulated and prodded by political entrepreneurs who have an interest in inter-group antagonism.

So the question here is this: what features of community life can be developed and cultivated that can serve as "shock absorbers" working to damp down the slide towards antagonism? What social features can make a multi-group community more resilient in face of provocations towards separation and mistrust?

Without pretending to offer a full theory of inter-group community stability, there are a few measures that seem to be conducive to stability.

First, the existence of cross-group organizations and partnerships among organizations originating in the separate groups, seems to be a strongly stabilizing feature of a multi-group society. The presence of a group of leaders who are committed to enhancing trust and cooperation across group lines provides an important "fire break" when conflicts arise, because these leaders and organizations already have a basis of trust with each other, and a willingness to work together to reduce tensions and suspicions across groups.

Second, person-to-person relationships across groups (through neighborhoods, places of work, or family relations) provide a basis for resisting the slide towards suspicion and fear across groups. If Chandar and Ismael are friends at work, they are perhaps less likely to be swayed by Hindu nationalist rhetoric or Islamic separatist rhetoric, and less likely to join in a violent mob attacking the other's home and community. Neighborhood and workplace integration ought to be retardants to the spread of inter-group hostility.

Third, policing and law enforcement can be an important buffer against the escalation of ethnic or religious tensions. If a Muslim shop is burned and the police act swiftly to find and arrest the arsonist, there will be a greater level of trust in the Muslim community that their security interests are being protected by the system of law.

Intergroup violence is the extreme case. But the separation of communities into mutually fearful and mistrustful groups defined by religion, race, or ethnicity is inherently bad, and it has the prospect of facilitating intergroup violence in the future. So discovering practical mechanisms of resilience is an enormously important task in these times of division and antagonism presented by our national political leaders.
