Abstract
Religion serves as an important source of beliefs for many across the world yet we know little about how religion and religious leaders contribute to belief formation. In this study, I exploit a unique partnership with the Punjab Auqaf Department in Pakistan, responsible for running state religious properties, to experimentally vary sermon content in 300 mosques and evaluate the causal impact of religious sermons on mosque-goers' social beliefs and behavior. By randomizing imams to sermon scripts emphasizing the importance of community rights and women's rights, I explore the importance of religious messaging for prosociality towards neighbors, community engagement, and attitudes towards women's social and economic participation.

Interventions

Intervention(s)
In the presence of uncertainty, beliefs drive decision-making. For example, beliefs about the importance of community, women’s appropriate role in society, and prevailing social norms all factor into decisions such as whether to act prosocially towards neighbors or support women’s labor market participation. Previous work has demonstrated how changing beliefs can engender positive social change (Bursztyn et al., 2020). However, belief formation, and the role of past experiences, religion, media, schooling, and local leaders therein remains understudied.

In this project, I focus on religious leaders and study the importance of one source of information in Muslim society for belief formation: sermons. Delivered before the Friday congregational prayer by an imam, the sermon, or khutbah, is often considered one of the most important sources of spiritual, social, and moral guidance for Muslims. While such messaging may partially help explain the strong correlation between moralistic religion and prosociality observed globally (Caicedo et al., 2023), concern has been raised about the potential for sermons to preserve conservative social norms but evidence is lacking. Since the information in sermons is public, the audience often exclusively male, and the source a local religious leader, a causal evaluation of Friday sermons offers a unique opportunity to study belief formation in the presence of others, intra-household belief transmission, the sources of religious leaders' authority, and the potential for sermons to serve as policy tools for information transmission.

To this end, I work with the Punjab Auqaf Department, which is responsible for running state mosques, to randomize sermon content and evaluate effects on individuals' beliefs and behavior. I study impacts on prosociality towards neighbors and attitudes about women's economic and social participation to further our understanding of the role of religion, religious leaders, and religious messaging in shaping social beliefs and behavior.
Intervention (Hidden)
I randomize sermons across the following domains: 1) topic (community rights or women's rights), 2) framing (fully religious or partially secular), and 3) information sharing (whether the imam encourages sharing of sermon content with wives or not).

Secondary Outcomes (explanation)

Experimental Design

Experimental Design
The study is a randomized control trial implemented in collaboration with the Punjab Auqaf Department. To evaluate the role of religious leaders and religious messaging in shaping beliefs and behavior, Auqaf imams, who are state employees, will be given sermon scripts and expected to deliver them verbatim. Enumerators will record the sermon delivered to evaluate compliance.

300 Auqaf imams will be randomized to either a business-as-usual control condition, treatment 1 (sermon scripts on women's rights), or treatment 2 (sermon scripts on community rights). Randomization will be stratified by whether the mosque is commercial or residential and congregation size (categorized into three bins).
Experimental Design Details
Imams will be asked to cover sermon content over two Friday sermons. The sermon script on women's rights will emphasize: 1) the importance of kindness towards women, and 2) the importance of women's economic and social participation. The sermon script on community rights will emphasize: 1) the importance of maintaining friendly relations with neighbors, 2) the importance of mosques as community centers, 3) the importance of keeping the community clean.

Each of the treatments will end with an actionable activity that the imam will ask mosque-goers to perform to put the lessons of the sermon into practice. In the case of the women's rights treatment, the imam will encourage men to spend an additional hour the following week discussing aspirations for daughters with wives. In the community rights treatments, the imam will encourage men to pick up garbage in their community.

15 individuals will be surveyed from each mosque to evaluate the effect of the treatment on beliefs and behavior. Wives will be surveyed over the phone where possible (i.e. both husband and wife consent). Each imam will also be surveyed to evaluate the impact of sermon delivery on the imams themselves.

Variations in the different treatment arms are described below:

Control: Business-as-usual sermons

Women's Rights:
- Treatment 1a: religious framing and information sharing script
The importance of respecting women's rights will be framed entirely in religious language as a religious obligation. The sermon will end with the imam encouraging men to convey sermon information to wives.

- Treatment 1b: religious framing and no information sharing script
Same as treatment 1a except the imam will not encourage men to convey sermon information to wives.

- Treatment 1c: secular framing and information sharing script
The last quarter of each women's rights sermon will be framed in secular language with the imam emphasizing the importance of respecting women's rights for non-religious reasons (e.g. the importance of women's employment for household income). The sermon will end with the imam encouraging men to convey sermon information to wives.

- Treatment 1d: secular framing and no information sharing script
Same as treatment 1c but the imam will not encourage men to convey sermon information to wives.

Community Rights:
- Treatment 2a: religious framing and information sharing script
The importance of community rights will be framed entirely in religious language as a religious obligation. The sermon will end with the imam encouraging men to convey sermon information to wives.

- Treatment 2b: religious framing and no information sharing script
Same as treatment 2a except the imam will not encourage men to convey sermon information to wives.

- Treatment 2c: secular framing and information sharing script
The last quarter of each community rights sermon will be framed in secular language with the imam emphasizing the importance of respecting community rights for non-religious reasons (e.g. the health benefits of maintaining community cleanliness). The sermon will end with the imam encouraging men to convey sermon information to wives.

- Treatment 2d: secular framing and no information sharing script
Same as treatment 2c but the imam will not encourage men to convey sermon information to wives.

Experiment Characteristics

Sample size: planned number of clusters
300 Mosques
Sample size: planned number of observations
4500 male mosque-goers (and wives for those who consent); 300 imams
Sample size (or number of clusters) by treatment arms
-Control (100 mosques): Business-as-usual sermons

-Treatment 1a (25 mosques): Fully religious sermon on women's rights with information sharing script
-Treatment 1b (25 mosques): Fully religious sermon on women's rights with no information sharing script
-Treatment 1c (25 mosques): Partially secular sermon on women's rights with information sharing script
-Treatment 1d (25 mosques): Partially secular sermon on women's rights with no information sharing script

-Treatment 2a (25 mosques): Fully religious sermon on community rights with information sharing script
-Treatment 2b (25 mosques): Fully religious sermon on community rights with no information sharing script
-Treatment 2c (25 mosques): Partially secular sermon on community rights with information sharing script
-Treatment 2d (25 mosques): Partially secular sermon on community rights with no information sharing script
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
I compute the MDE for allocations in dictator games and community cleanliness from my pilot data. I estimate that the MDE when I pool my religious/secular and information sharing/no sharing treatments is 0.13 SD for allocations in dictator games and community cleanliness. The MDE for comparing the sub-treatments to each other (e.g. religious vs secular or information sharing vs no sharing) is 0.17 SD for allocations in dictator games and community cleanliness.
