1. Introduction
Religious tensions and violence have risen globally over the last decade. The
Pew Research Center (
2018), for example, has reported that 28% of countries had “high” or “very high” levels of government restrictions on religious freedom in 2016, a three percentage point increase from 2015. The report also mentioned that among the 25 most populous countries in the world, Egypt, Russia, India, Indonesia, and Turkey had the highest levels of religious freedom restrictions. Religious tensions have the potential to quickly turn violent. The
Minority Rights Group International (
2018), for example, has recorded that mass killings and other atrocities involving religious minorities have been increasing in many countries.
Despite the country’s progressive democratic reform after the fall of the Suharto regime in 1998, Indonesia has witnessed the rising political and social power of hard-line Islamists and a turn towards populist conservatism in recent years (
Hadiz 2018;
van Bruinessen 2013;
Wilson 2017;
Rakhmani 2017). More concerning, several micro-level surveys have indicated that religious intolerance among Indonesians has also been on the rise. The combination of rising Islamic political conservatism and religious intolerance attitudes has reduced social cohesion and is incompatible with democracy.
In this paper, we explore the socio-economic predictors for individual-level religious intolerance in Indonesia. To identify the relevant predictors, we consider religious intolerance as a variant of out-group prejudice and take theoretical insights from sociology and social psychology on the determinants of such prejudice. We do not lend any particular weight to specific theories in selecting our socio-economic predictors, but use all possible theoretical explanations from the scarce resources theory, threat theory, social contact theory, educational progressivism theory, and community theory, as predominantly summarized in
Mulder and Krahn (
2005) and
Stolz (
2006). We also consider that religiosity itself may shape intolerant attitudes (
Allport 1966). While all of these theories have been confirmed by many empirical studies (see, e.g.,
Milligan 2012), to the best of our knowledge, no empirical study has tested these theories in the Indonesian context.
Methodologically, we run multivariate regressions of religious intolerance on several socio-economic covariates at an individual level, mainly from the longitudinal Indonesian Family Life Survey (IFLS) data from 2007 and 2014. We find that richer and more educated individuals tended to be more tolerant to people with a different faith, supporting the scarce resources and threat theories, and that more self-declaring religious individuals tended to be less tolerant. We also confirm that community is important: individuals who resided in an area with higher income inequality and a greater extent of poverty tended to have less religious tolerance. The associations between these predictors and religious intolerance were persistent across different measures of religious intolerance, despite the heterogeneity in the magnitudes of the correlations.
This paper is organized as follows. First, we provide an overview of religious intolerance in Indonesia, which motivates this study, in
Section 2.
Section 3 is a literature review specifically presented for developing an analytical framework for the empirical analysis. The methodology and econometric specifications are discussed in
Section 4, followed by the empirical findings in
Section 5.
Section 6 concludes the paper.
2. Overview of Rising Conservatism and Religious Intolerance in Indonesia
With 225 million Muslims, which constitute 87% of its total population, Indonesia is the largest Muslim country in the world. Further, with sweeping democratization in 1998, it is also the largest Muslim democracy. Indonesia has also been known for having a history of religious harmony. However, since its independence in 1945, the country has seen a long history of political competition between nationalistic secularism and Islamism. The ‘latent’ force of Islamic identity in politics was repressed during the authoritarian New Order between 1966 to 1998. The collapse of this regime, which led to a democratic reform, provided room for everyone, including Islamic-based political organizations, to become more open and expressive. The World Gallup Poll
1, for example, ranked Indonesia among the most religious countries in the world.
Religious tolerance has been one of the main features of Indonesian society, as described by numerous discourses and depicted by the mass media at least until the reform period starting in the early 2000s. During Suharto’s rule of power, Indonesian Muslims have been known, at home and abroad by the general public, academicians, and politicians, as moderate, friendly, and tolerant. At that time, most (if not almost all) scholarly accounts on Indonesian Islam described Muslims in the country as the perfect example of moderate Islam, particularly in comparison with their fellows in the Middle East (
Wanandi 2002;
Dibb 2001;
Ni’am 2015).
However, post-New Order Indonesia has offered different narratives of Indonesian Islam. Following the end of Suharto’s era, jihadi movements, with the support of military factions and local interests, fought in religiously motivated armed confrontations in the Maluku and Central Sulawesi provinces (
van Dijk and Kaptein 2017). Terrorists attacked churches in 2000 and a tourist destination in Bali in 2002, which was repeated annually until around three years later, and cited Islam as their source of inspiration (
Bagir 2014, p. 29). The calling to re-include the Jakarta Charter (a document that placed an obligation on Muslims to abide by Islamic law) in the Constitution was made by a few political parties in 2001 and 2002. At the sub-national level, many provincial and district local governments have tried to implement Islamic law, initiated not only by Islamic political parties but also by the secular ones.
Muslim rejections of practices of different faiths, often followed by violent acts, as well as of the presence of houses of worship of other faiths, have also become more frequently reported in the media (
van Dijk and Kaptein 2017, p. 14). In Bogor, West Java, against a Supreme Court Order, some Muslim hard-liner and local government groups continued to use force to prevent Christian churches from holding religious services in 2011. There were also attacks threatening Buddhist sites, along with the destruction of one of the last synagogues in Indonesia (
Christian Solidarity Worldwide 2014).
Many of these intolerant acts have been perpetrated by the FPI (Islamic Defenders Front), a militia group established on 17 August 1998 by, as many believed, top figures in the military and police and their associates. Since then, the FPI, with their burgeoning number of followers—approximately two million, coordinated through local representatives in 26 provinces—and the fact that they seem to be able to escape law enforcement actions despite committing vigilante and sometimes violent acts, has been deemed by many observers to be a symbol of religious intolerance in Indonesia.
While the aforementioned cases were associated with minority-but-vocal Islamic hard-liners, attitudes on Islam and relationships with non-Muslims amongst Indonesian Muslims have been adversely transformed, too. This changing attitude has been exemplified by discrimination against Ahmadiya and Shia, as well as opposition to non-Muslims building places of worship in the area
2.
Moreover, the emerging popularity of Hizbut Tahrir—a transnational organization championing the caliphate system over democracy—among young people in universities, particularly in non-denomination campuses and in high schools serves as another example of the rise of intolerance. The Hizbut Tahrir had one million followers in 34 provinces and 402 municipalities/cities in 2017 (
Tempo Magazine 2017). The growing popularity of the Hizbut Tahrir among university students relative to KAMMI (Indonesian Muslim Student Action Movement)—another movement that has been conservative but more moderate since 1998—may suggest a shift toward right-wing conservatism among young educated Indonesians.
Some micro-evidence has also supported rising public intolerance, suggested by a series of incidents and the growing popularity of radical Islamist organizations. Recent evidence came from a nationally representative survey carried out by Lembaga Survei Indonesia (LSI) of about 1500 respondents, as shown in
Figure 1. It showed a clear pattern of rising religious intolerance concerning elected official positions in the last three years. In just a short period between 2016 and 2018, the share of Indonesian Muslims who objected to a non-Muslim presidency increased by 11 percentage points, from 48 to 59 percent. Similar patterns also emerged for the lower ranks of elected public officials.
There is also initial evidence that the religious intolerance of voters may have effectively shaped Indonesian politics. A nationwide survey of intolerance of at least 300,000 households in 2014 (SUSENAS data) suggested a clear correlation between the 2019 presidential election results and the religious intolerance level in 2014. In the 2019 presidential election (as well as in the previous election in 2014), the president/vice president candidates Jokowi/Ma’ruf, perceived as nationalist and representing a more moderate form of Islam, directly competed against the candidates Prabowo/Sandi, who were supported by more conservative Islamists (
Gueorguiev et al. 2018). Interestingly, as shown in
Figure 2, we find strong cross-provincial correlations between various types of religious tolerance and votes for Jokowi/Ma’ruf in the 2019 election: in less tolerant provinces, the more moderate candidates Jokowi/Ma’ruf gained a lesser percentage of the total votes. The statistical correlations are too high to be ignored.
The effect of religious intolerance on electoral politics may also be illustrated by the case of the election of the governor in Jakarta in 2017. Basuki Tjahaja Purnama (a.k.a. Ahok), the outspoken incumbent non-Muslim governor of Jakarta, a rising star in Indonesian politics despite his minority background, was accused of committing blasphemy against Islam
3 (
Kato 2017, p. 79). After heavy media coverage of his trials, including a live reportage, Ahok was eventually sentenced to jail and lost in the election. Previously the most popular candidate, he could not survive public campaigns from Islamist groups against voting for the non-Muslim candidate.
Other than these electoral politics-related incidences, a series of one-time surveys on the topic have also provided static snapshots of a strong tendency for religious intolerance in recent years. For example, Pusat Pengkajian Islam dan Masyarakat of the State Islamic University (UIN) of Jakarta, in their survey of radicalism amongst 2237 school teachers, found that 50 percent of respondents supported the idea of a Muslim-only Indonesia. The same study found that 33 percent objected to having another faith’s place of worship built in the neighborhood (
PPIM-UIN 2019). A survey conducted by the PPIM (Centre of Study for Islam and Society) of UIN (State Islamic University) revealed that more than 80 percent of five hundred Islamic teachers refused to have non-Muslim leaders or the establishment of a non-Islamic place of worship in their neighborhood. They also tended to reject the existence of non-Muslim teachers in their respective schools. The Centre of Study for Religion and Democracy of Paramadina University, the Wahid Institute, and the Ministry of Religious Affairs have also obtained more or less similar results in their research.
Earlier,
PPIM-UIN (
2018) also found a similar pattern among students. Eighty-seven percent of 1859 surveyed students agreed that the government should ban minorities whose religious practices did not adhere to (mainstream) Islam, such as Ahmadiyah. A survey by the Ministry of Religious Affairs and Wahid Foundation (
Wahid Foundation 2016) found that 75 percent of 1600 senior high schoolers supported the caliphate system, around 30 percent understood jihad as fighting with arms against the infidels, and around 60 percent were ready to fight in conflict areas such as Palestine and Syria. Beyond surveys of perception, the Setara Institute (
Setara Institute 2009,
2011,
2013) also reported an increasing trend of acts of intolerance between 2007 and 2012.
3. Literature Review
Where is all this rising Islamic conservatism rooted? We argue that there are strong socio-economic factors behind the rising religious intolerance in Indonesia. As a variant of prejudice against the outside group (such as race, ethnicity, or status-based migrant discrimination), the social and economic determinants of such intolerant attitudes at an individual level have been widely discussed and debated in the literature of various disciplines.
In this section, we discuss the relevant theoretical and empirical literature on the determinants of an individual’s prejudice toward outside groups, in order to develop our analytical framework. We adopt theoretical insights from sociology, psychology, and economics to generate possible explanations on why an individual could become less tolerant to an outside group, in general, and apply them to our specific context of religious intolerance. We also explore the related empirical studies, including (but not limited to) the determinants of religious intolerance. To the best of our knowledge, this paper will be the first quantitative study that connects religious intolerance and socio-economic variables at the individual level using large-scale longitudinal survey data in Indonesia—a country that is arguably among the most strategically important in the context of rising Islamic conservatism.
Drawing from the literature in sociology and psychology,
Mulder and Krahn (
2005) and
Stolz (
2006) have provided useful summaries of the classification of theoretical approaches on the determinants for outgroup intolerance: scarce resources theory, social contact theory, educational progressivism theory, and community theory.
The scarce resources theory views society as comprising opposing groups, with the most powerful controlling resources and attempting to maintain their advantaged positions (see, e.g.,
Smelser 1988;
Dahrendorf 1959). In this setup, outsiders (such as religious minorities) are seen as threats or competitors that may potentially take away the resources of the majority through means such as labor-force advantages or business opportunities. A variant of this theory is referred to as social identity theory, which also predicts that inter-group conflict instigates feelings of intolerance (
Milligan 2012), such that people with less economic security are more likely to feel vulnerable to minorities. The observable implication of these theories is that an individual with job market insecurity and lower economic status (i.e., low income) is more likely to be more intolerant of people with different faiths.
Social contact theory—also called intergroup contact theory in social psychology (see, e.g.,
Hodson 2011)—suggests that more experiences change attitudes. The argument goes that individuals with more contact with the outside groups (such as people with different faiths) will come to know them better, feel less threatened, and be more likely to accept them as part of their community. The empirical evidence of this theory has been well established.
Pettigrew and Tropp (
2006), for example, conducted a meta-analysis of 515 studies and found that intergroup contact typically reduced intergroup prejudice. One of the observable implications of this theory is that people who experience more mobility (socially or geographically) tend to be more tolerant.
Educational progressivism theory, as a part of modernization theory (see e.g.,
Lipset 1959), implies that education reduces prejudice. This idea relies on the role of (liberal) education in promoting acceptance toward outside groups and that an individual learns to become more tolerant through education. Empirically,
Mulder and Krahn (
2005),
Guimond and Palmer (
1989), and
Chandler and Tsai (
2001) confirmed that learning to be tolerant happens at schools, colleges, or universities. Educational attainment has been shown to generally lead to more appreciation and tolerance of other social groups (
Jackman 1978;
Coenders and Scheepers 1998). If this theory holds, individuals with higher educational attainment tend to be more intolerant to those with different religions.
Community theory, proposed by
Mulder and Krahn (
2005), argues that the spatial community—the location—plays a significant role by providing the context within which group interactions take place and attitudes and beliefs are shaped. Specific community characteristics, such as population density or social inequality, can generate negative attitudes toward people from different groups. The economic development of a community also affects individual prejudice, as demonstrated by
Andersen and Fetner (
2008), who found that a combination of economic growth and increasing inequality had a significant contribution to intolerant social attitudes and values. One observable implication of this theory is that poverty and inequality in the community where an individual lives have strong associations with higher religious intolerance, which has been confirmed by
Milligan (
2012) in his cross-country study.
Another strand of literature links prejudices with the level of religiosity (see, e.g.,
Scheepers et al. 2002). Starting with the seminal works of
Allport and Kramer (
1946) and
Allport (
1966) in social psychology, this line of thought suggests a positive correlation between religious commitment and prejudice (particularly, racial prejudice). While this theory has mainly focused on racial or ethnic prejudices, it is natural to expect an even stronger positive association between religiosity and the level of intolerance to people with different religions.
Specific to the determinants of religious intolerance, most existing empirical studies have agreed with the scarce resource and social identity theories. Lower job security, income, and other variables that measure social and economic status have been associated with higher intolerance to people of different religions. For example,
Moors (
2004),
Reutter et al. (
2006), and
Haubert and Fussell (
2006) found that income level affected the ability to tolerate minorities.
Strabac and Listhaug (
2008) also found similar effects with respect to an individual’s job security. On the other hand,
Hughes (
2013) and
Moore and Ovadia (
2006) confirmed that an individual’s level of religiosity is strongly associated with their level of religious intolerance, which serves as a confirmation of religiosity theory.
For the community theory,
Milligan (
2012) and
Wilson (
2017) found that an income or wealth gap in the location where an individual lives adversely affected religious tolerance.
Millington (
2016) and
Finke and Stark (
2003) showed that individuals who live in cities (urban settings) tended to be more tolerant, simply because they lived in a culturally, ethnically, or racially diverse environment, relative to those who live in rural areas.
5. Findings and Discussion
Our main findings are presented in
Table 2 and
Table 3.
Table 2 gives the estimates based on the Conditional Fixed-effects Logit Model and
Table 3 is based on the model where the index of a combination of five different intolerances was used as the dependent variable. We also present regression results, based on different measures of inequality indicators (Gini coefficient and Income share of the richest 10%, 5%, and 1%), in the
Appendix A. Furthermore, for the purpose of comparison, we also report the regression results using the Linear Probability Model (LPM) in the
Appendix A.
We found that, in general, an individual’s income level was negatively associated with their level of religious intolerance. Therefore, individuals with higher levels of income tended to be more tolerant of various kinds of interactions with others of different faiths, except for inter-faith marriage involving a relative. In other words, people with higher incomes (such as the rich) tended to have lower levels of religious intolerance, while people with lower incomes (such as the poor) tended to have stronger levels of religious intolerance. It should be noted that this relationship was conditional on our controlling for other factors that may have also affected religious intolerance. These correlations were in line with the predictions from social identity theory or scarce resource theory, which suggest that prejudice or intolerance against people outside their own religion is driven by a perceived threat to economic opportunities (
Smelser 1988;
Dahrendorf 1959).
To address the possibility of a non-linear relationship between income (per capita expenditure) and religious intolerance, we ran different regressions with different specifications for the income variables. Instead of using expenditure per capita as a continuous variable, we divided it into quintiles (five categories of expenditure per capita), from low to high income. We converted the category into four dummy variables (quantiles 2–5), with quintile 1 as the reference category. The results (
Table 4) suggest that the coefficients of the quintile variables were noticeably different, suggesting a non-linear relationship. In particular, we found that only quintiles 3–5 had coefficients that were statistically significant at the standard level. The statistically insignificant coefficient of Quintile 2 suggests that income did not affect (reduce) religious intolerance in the low domain of income. In other words, we need to reach a certain point of income to find a negative association between income and intolerance.
Nevertheless, the relatively low correlation between income levels with acceptance of inter-faith marriage in the family merits an explanation: One possible explanation is that accepting a marriage to a non-Muslim, particularly for women, is probably the strongest form of tolerance as, based on standard Islamic teaching in most Muslim majority countries, inter-faith marriage is prohibited or is very difficult to do (
Law Library of Congress 2015)
6. This rule, however, is more relaxed for men, as men are still allowed to marry non-Muslim women under certain conditions (but not the other way around). Such a strict tolerance benchmark is reflected in the relatively low coefficients of income level for interfaith marriage. In the conditional fixed-effect logit model (correcting for the non-linearity of the prediction of non-tolerance), the level of income was not statistically significant.
Quality of employment has also generally been negatively associated with religious intolerance. Lending more support are the scarce resource or social-identity theories, where religious intolerance is an expression or response to what an individual considers to be a perceived economic threat from an outside group (in this case, religious minorities). The coefficients of having a secure job were negative and significant in three out of four regressions in the specification with overall intolerance index as the dependent variable.
Moreover, our regression analysis confirmed that education mattered, but only at a certain level of education. A statistically significant association only occurred when an individual’s educational attainment was higher than junior-secondary school, especially for university-level education or higher. In other words, people with a university education tended to have stronger level of tolerance of others with different religions than people who did not have a university education (after taking the effects of other variables into account). This finding supports either the education progressivism theory or the social contact theory. In line with social contact theory, in Indonesia, besides academic skills, university students have much wider opportunities to interact with a more diverse group of individuals coming from all over the country, including regions with a different religious majority (e.g., non-Islam North Sumatera or Eastern Indonesia). Educational progressivism theory is harder to explain, as there was no substantial evidence to suggest that tertiary education is significantly more progressive. In fact, many reports (see
PPIM and UNDP 2018) have suggested that schools and universities, especially elite universities, tend to be breeding grounds for religious conservatives, even more so than the traditional educational institution of
pesantren7.
Our findings that only exposure to tertiary education had a robust association with religious tolerance deserves further explanation: As suggested by various studies (e.g.,
Kurniawati et al. 2018), Indonesian basic and secondary education has not yet been translated into an improvement in learning. Thus, the non-significant influence of primary and secondary education on religious intolerance may simply reflect the general low quality of education in Indonesia. However,
Beatty et al. (
2018) showed that, in fact, learning outcomes are very low (and declining) at all educational levels, including the tertiary level. Combined with the reported rising trend of conservatism in universities, a more likely explanation is that exposure or contact with more diverse groups compensated for the non-existent or decreasing educational progressivism effects in schools and universities. The fact that education, particularly primary and secondary education, does not lead to social progressivism in Indonesia poses serious policy challenges.
We also found that the level of (self-declared) religiosity was highly associated with religious intolerance. In other words, individuals who believed that they were more religious tended to be more intolerant of others with a different faith. Using the baseline (or point of comparison) of an individual who claimed he/she was not religious, the size of the coefficients of the dummy variables of each level of self-declared religiosity increased. The significant positive associations between religiosity and religious intolerance were robust to all measures of intolerance and model specifications. In fact, religiosity was the only variable at the individual level that had a strong and statistically significant association with all kinds of religious intolerance, including inter-faith marriage.
Our findings on the strong influence of religiosity on intolerance in Indonesia agree with the general findings of the empirical literature on the subject (
Allport and Kramer 1946;
Allport 1966;
Scheepers et al. 2002;
Hughes 2013;
Moore and Ovadia 2006). As discussed in the introduction, the rising tendencies of religious intolerance in Indonesia are concerning. The IFLS data of 2007 and 2014 show an increasing trend of religiosity. In 2007, for example, out of around 29,000 IFLS respondents, only 5.4% claimed to be ‘very religious’. Seven years later, in 2014, this figure increased to 16.4%. If religious tolerance is a desirable societal objective and target of policy intervention, then the government needs to find ways to mediate the effects of increasing religiosity on religious intolerance. One way of doing this is to promote and strengthen the teachings of moderate Islam, which have had a long tradition in the country.
Another cross-national study was undertaken by
Norris and Inglehart (
2011). They used the concept of existential security to explain that people under circumstances of existential insecurity tend to be more attracted to religion than people with a higher level of security do. They concluded that a sense of vulnerability driven by economic inequality enables the rise of religiosity. Our study provides an additional explanation for their thesis on the correlation between human development and religiosity. Unlike for our study, theirs did not specifically address whether people that are increasingly interested in religion (more religious), become increasingly less tolerant. However, they did find that there was no positive association between religiosity and tolerance in any countries (except for the U.S.A.) and that participation in religious activities is correlated with a low level of social capital, which could partially explain the rise of intolerant practices.
Furthermore, we used three variables to test the community theory: location (urban or rural area), inequality (Gini coefficient or income share of the richest within districts), and the extent of poverty. It turned out that residential status—living in an urban or rural area—was generally not associated with the individual level of religious intolerance. However, we found that inequality and the extent of poverty were strongly associated with the individual level of intolerance. Individuals living in municipalities with higher income inequality had a stronger tendency to be less tolerant of others with different religions, taking into account other factors that may affect intolerance. These associations were robust across all types of religious intolerance, as well as across the inequality measures considered: Gini coefficient and the income share of the richest 10%, 5%, and 1% of the population (see the
Appendix A for the results using inequality indicators other than Gini coefficient). This result confirms the results several other studies, such as
Andersen and Fetner (
2008) and
Milligan et al. (
2014), both of which used World Value Survey data. The findings of
Milligan et al. (
2014), in particular, were closer to those of this paper, as they used individual-level data from 23 Muslim-majority and western countries. Specific to Indonesia, we observed that the period of rising Islamic conservatism and intolerance coincided with a period of rising inequality, culminating in 2011 when the national Gini coefficient reached a physiological threshold of 0.40 (
Yusuf et al. 2014).
In support of the community theory, our regression analysis also suggested that individuals tended to be more intolerant if he/she lived in a city with a larger number of poor people. The coefficients of poverty—the number of people who live below the national poverty line—were positive and statistically significant in all model specifications. We interpret this as the visibility of poverty adversely affecting religious intolerance.
It is natural to argue that the effect of income on religious intolerance is more pronounced in mostly poor communities than in less poor communities. To test this, we included the interaction of expenditure per capita and the number of poor people in the communities. The result (as reported in
Table A5 in the
Appendix A) did not support such ideas, as the coefficient of the interacting variables were insignificant at the standard level in all types of intolerance regressions.
We compared and contrasted the results between the different dependent variables (different types of intolerance) by comparing the statistical significance and the strength of the association of the same variables on different kinds of intolerance (dependent variables). It should be noted that one can interpret moving from column one to column four as getting more personal, in terms of direct interaction. For example, the dependent variable in column one represents whether an individual objected to others with different religions living in the same village (i.e., sharing the same village). As we move to the second column, the dependent variable is whether an individual objected to others with different religions living in the same neighborhood (i.e., sharing the same neighborhood). In the third column, the dependent variable is whether an individual objected to others with different religions sharing a room in one’s house (cohabitation). Finally, column four is for the dependent variable of whether an individual objected to others with different religions marrying his/her relative. Thus, there is a gradient of personalization of interaction from the dependent variable in column 1 to column 4. The dependent variable in the last column (whether an individual objected to others with different religions building a place of worship) should be regarded as not directly related to the gradient of closeness of potential interaction. That being said, we noticed that the association between religiosity and intolerance was similarly strong across the different dependent variables.
By comparing the strength of the influence of the same variables on different types of intolerance, we highlight the following: First, for at least the three variables of income, job security, and having a university education, the effect on intolerance was weakened as we move from the intolerance of others with a different religion living in the same village, then the same neighborhood, and then the same house. In other words, the more personal the interaction, the less powerful the effect of those variables on reducing intolerance. As discussed previously, none of these three variables were associated with intolerance to inter-faith marriage to family members. Second, we did not see any systematic pattern across different dependent variables on the effect of religiosity among the most robust predictors of intolerance, as well as intolerance itself. However, unlike the effects of income, job security, and tertiary education, intolerance of inter-faith marriage to family members was strongly affected by level of religiosity. Finally, the effects of inequality and poverty were practically similar across different types of intolerance.
Our findings that inequality is strongly correlated with religious intolerance contribute to the already political economic debates on the issue. With an increasing trend of inequality in many countries, including Indonesia, our findings provide additional support for the urgency of reducing inequality and poverty beyond economic redistribution, as both also undermine social cohesion and increase divisive identity politics. Policy-wise, our findings also lend support for the development of better social protection and related taxation policies.
6. Conclusions
In this paper, we have shown that Indonesia, the largest Muslim democracy, faces both democratization and rising Islamic conservatism. The rise of conservatism has also been accompanied by an increase in religious intolerance amongst Indonesians, posing a serious threat to the idea of pluralist democracy and a moderate Islam.
Against this backdrop and drawing from the sociological and psychological literature, we developed possible predictors for an individual’s level of religious intolerance in Indonesia. We then tested the plausibility of those predictors in explaining the recent rise of religious intolerance at the individual level by using longitudinal Indonesian Family Life Survey (IFLS) data from 2007 and 2014 and employing fixed-effects regression analysis.
Our results support the scarce resource theory, as we found that an individual’s income level and quality of employment were generally positively associated with his or her level of religious tolerance. We also found that having a tertiary education was positively associated with religious tolerance and tended to assign effects confirming the social contact theory, instead of observing the effects of educational progressivism. We also found that religiosity was associated with a stronger level of religious intolerance. This finding confirms what is known as the religiosity theory of intolerance. In support of the community theory, we found a strong and robust association between the level of inequality and the extent of poverty in the district where an individual resides with his/her level of religious intolerance. Individuals living in municipalities with higher income inequality and a larger number of poor people tended to have a stronger level of religious intolerance.
If religious tolerance is a socially desirable objective, as well as a subject of public policies, what can these findings tell us? Our analysis provides some clues as to the best predictors of the rising religious intolerance in the 2000s. In the 2000s, income inequality rose rapidly and Islamic conservatism showed an increasing trend. These two factors were among the most robust predictors of religious intolerance based on our regression analysis. Meanwhile, in order to reduce religious intolerance, the following policies should be consistent with our findings: The first involves supporting more moderate Islamic teaching, which already has a long tradition in the country. Moderate Islam may support the notion that being religious is not mutually exclusive with being tolerant. The second involves accelerating the increase in access to higher education. Not only this will increase the skills of Indonesian youth, but it will also expose them to a diverse, multi-cultural, and plural society. Thirdly, any policies to reduce income inequality should be supported, not only based on economic justice, but also based on the ideal of religious harmony.
Finally, we acknowledge that our study has several shortcomings. First, our analysis does not establish causation. To identify causation, we need to assume the exogeneity (pure randomness) of all the covariates, which was not the case, or to find other methods to correct for endogeneity in the covariates, such as using instrumental variables. Finding these exogenous instruments can be a challenge. Secondly, in testing the community theory, such as the effect of inequality on religious intolerance, many individuals within the same community are exposed to the same level of inequality. A multi-level regressions analysis can potentially do better in drawing statistical inferences in this kind of situation. While acknowledging these important shortcomings, we leave them for further research.
