Introduction
Moral life begins in obligations whose reach and meaning people do not always share. What makes an act wrong? What do we owe a stranger, a relative, or a community? Religion may enter through belief, ritual, institution, or identity. Understanding these connections requires us to keep a judgment about goodness distinct from an act of cooperation and from a person's moral reputation.
This path begins with a relational theory of morality and a study that challenges a narrow definition of the moral domain. It then compares evidence about intentions and fairness before examining the different components of religion and their possible connections with behavior. A ritual study and a comparative allocation task raise questions about who benefits from cooperation. Historical modeling asks whether particular religious features precede political complexity. The final pair distinguishes moral from religious conviction and examines prejudice toward nonbelievers.
The ten readings across six units combine conceptual arguments, comparative studies and historical inference. The long religion-and-morality review and the historical model are the most demanding works; allow several sittings and use the guides to keep the main distinctions in view. By the end, you should be able to specify which belief, practice or relationship an explanation concerns, identify the outcome it predicts, and distinguish evidence about people’s moral reputations from evidence about their actions.
Unit 1 of 6
What counts as a moral concern?
A theory needs a defensible account of what it explains. Rai and Fiske organize moral motives around relationships; Haidt and colleagues investigate judgments that a narrow focus on obvious harm might miss. Treat both the framework and the boundary of the moral domain as questions to examine.

Compare the proposed relationship models and the kinds of obligation they create.
Why you’re reading it. Begin with a theory that can explain disagreement without treating one group as lacking morality.
A question to consider. Two families disagree about whether support should follow need, equal shares or past contributions. How would the framework explain the disagreement, and what evidence could challenge its explanation?

Landmark empirical study · Moderate · Full work: 16 pages
Separate wrongness, perceived harm, emotional response and the authority of a rule.
Why you’re reading it. Examine how a definition of the moral domain affects the comparison between communities and social groups.
A question to consider. If a respondent says an apparently harmless act damages family dignity, how would the opening relational account and the study’s harm questions interpret that response?
Unit 2 of 6
How do intentions and distributions matter?
Moral evaluation depends on what happened, what someone intended and how responsibility is understood. Allocation choices pose another question: what costs will someone accept to resist inequality? Compare the evidence without assuming that judgments and actions reveal an identical motive.

Compare intention and mitigation effects across different acts, keeping within-setting variation visible.
Why you’re reading it. Test how a shared capacity to consider intentions can coexist with different rules about responsibility.
A question to consider. What further comparison would distinguish a local rule about accidental harm from a general tendency to ignore intentions?

Distinguish rejection of being worse off from rejection of being better off, remembering that rejecting the allocation leaves both children with nothing.
Why you’re reading it. Bring developmental behavior into a syllabus that began with adult and child judgments about stories.
A question to consider. What evidence would be needed to connect the costly rejection of an advantageous allocation with a community’s explicit moral teaching about fairness?
Unit 3 of 6
What connects religion and morality?
A single religiosity score can combine beliefs, practices and social participation that operate differently. McKay and Whitehouse provide a framework for separating them. Use the later-evidence qualification in the guide to avoid treating every illustrative finding as an established mechanism.

Major synthesis · Foundational argument · Challenging · Full work: 27 pages
Map proposed connections between particular religious components, psychological processes and outcomes.
Why you’re reading it. Form hypotheses precise enough to evaluate in the ritual, allocation and historical studies that follow.
A question to consider. For a claim that religious participation increases generosity, specify two different mechanisms, the recipients who might benefit and a result that would distinguish those mechanisms.
Unit 4 of 6
How might practices and beliefs affect cooperation?
The ritual study measures donations to a temple; the comparative study measures allocation to local and distant co-religionists. Both examine behavior, yet neither makes every religious feature experimentally independent. Ask what each outcome captures and where the cooperative boundary lies.

Methodological contribution · Moderate · Full work: 4 pages
Separate the donation result from proposed effects of pain, shared experience and identity.
Why you’re reading it. Apply the component framework to a concrete religious practice and its immediate social setting.
A question to consider. Would increased temple donations after an intense ritual establish broader generosity? Specify a recipient comparison and a selection issue that would need attention.

Distinguish measured punishment beliefs, experimental reminders and the identities of the recipients.
Why you’re reading it. Examine whether a proposed mechanism extends cooperation beyond the local group and how far that claim reaches.
A question to consider. How would adding a distant person from another religion change the question this allocation task can answer?
Unit 5 of 6
How can historical explanations be tested?
Evidence about present choices does not establish a historical sequence. Watts and colleagues use ethnographic coding and a model of relatedness to compare two religious features. The difference between broad punishment and moralizing high gods makes the definition of the proposed cause central to the explanation.

Methodological contribution · Challenging
Compare the two coded religious features and identify which parts of the historical sequence are inferred from a model.
Why you’re reading it. Move from individual behavior to claims about cultural change while preserving the distinction between levels of explanation.
A question to consider. If neighboring communities borrow both political arrangements and religious beliefs, how would that complicate the branching-history explanation?
Unit 6 of 6
Are moral conviction and religious identity interchangeable?
End by distinguishing a person’s moral commitments from the religious basis they report and from the moral reputation others assign them. These studies ask different questions: how attitudes are experienced and how stereotypes enter an inference. Neither measures which worldview makes people ethically better.

Methodological contribution · Moderate
Separate the conjunction-task inference, participants’ own beliefs and any claim about real-world behavior.
Why you’re reading it. Conclude by examining how an assumed link between religion and morality can itself shape social judgment.
A question to consider. What would distinguish an intuitive stereotype about atheists from an observed difference in conduct, and which of those questions does this study address?
Scope and omissions
The ten readings span conceptual reviews, cross-cultural comparisons, experiments and historical analysis. The conceptual review and historical analysis require the most sustained attention. Access notes distinguish journal articles from files that also contain supplementary material or use manuscript pagination.
The evidence includes communities in Brazil, the United States, Mauritius, Austronesia and broader comparative samples. These are selected settings, not representatives of every tradition or of entire national populations. The path does not settle ethical disputes, religious truth claims or the moral worth of believers and nonbelievers. It is not a comprehensive history of religions, an account of every Indigenous moral tradition or a systematic review of every proposed religious mechanism. Violence, exclusion and unequal authority remain relevant possibilities rather than evidence that all moral or religious commitments have the same effects. Optional works extend childhood distinctions, cooperation theory, evolutionary explanation, outgroup comparisons, later synthesis and replication.
Synthesis
A cultural inquiry into morality asks which obligations people recognize, how relationships organize them, and whose definition of the moral domain guides the research. Judgments of an act, costly choices, and reports about the basis of an attitude each disclose something different. Their connections deserve investigation, but none can simply stand in for the others.
Religious practices and beliefs may shape participation, monitoring and group boundaries, but the outcome and recipient must remain explicit. Giving to a temple is not the same as giving impartially to everyone. An association between beliefs and behavior is not an experimental effect of belief. A historical sequence reconstructed from coded features does not establish a universal path of social development. Moral conviction and religious conviction can overlap while remaining distinct; stereotypes about nonbelievers cannot establish how nonbelievers behave.
Choose a community practice involving an obligation or shared contribution. Describe the relevant relationship, the moral claim, the religious or nonreligious basis and the people who benefit or bear costs. Propose two explanations for participation and evidence that could distinguish them. Then identify a stereotype that an observer might mistakenly infer from your evidence, and explain why it goes beyond what was measured.
