Methods & Design (jcr-methods)

When to trigger

• You have a mechanism but are unsure how to test it
• Deciding between a behavioral-experiments paper and a CCT fieldwork paper
• A reviewer asks whether your design can actually support the process claim
• You are weighing a Registered Report for a confirmatory question

JCR is methodologically pluralistic by mandate

JCR states no single preferred method; the bar is a clear conceptual contribution supported by appropriate empirical evidence. In practice two flagship traditions coexist under one masthead, and you should commit to one design logic (or a principled mix):

• Theory-driven behavioral experimentation (the dominant tradition): multiple lab and online experiments that isolate a psychological process and its boundary conditions.
• Interpretive / Consumer Culture Theory (CCT): ethnography, depth interviews, phenomenology, or netnography that theorizes the sociocultural meanings of consumption.

The journal also publishes quantitative/modeling and methodological work. Choose the design the conceptual claim demands, not the one you find convenient.

Designing the multi-study experimental package

• Process evidence: plan studies that establish the effect, then mediation (measured or, more convincingly, moderation-of-process / manipulated mediator), then boundary conditions that the theory predicts.
• Internal validity: random assignment; manipulation checks and attention checks; pretested stimuli; counterbalancing; rule out demand and confounds by design.
• Robustness across studies: vary populations, stimuli, and operationalizations so the effect is not stimulus-bound; a convergent multi-study package is the JCR norm.
• Power & samples: a priori power analysis; specify and justify sample sizes and exclusion rules in advance. Overflow stimuli, full instruments, and additional replication studies belong in the web appendix (max 40 MB, excluded from the 60-page cap).

Designing interpretive / CCT work

• Justify site, informant selection, and immersion; show the data are rich enough to support conceptual claims.
• Plan for trustworthiness: triangulation, prolonged engagement, member checks, and an audit trail rather than p-values.
• Theorize as you go: the design should enable moving from thick description to second-order constructs.

Transparency is a design decision, not an afterthought

JCR's transparency regime shapes the design from the start: a Data Collection Statement is required for all submissions (Step 6), data/materials posting is required at invited revision unless exempt, and replication code must be provided. Build clean materials, preregistration where appropriate, and a repository plan (OSF / Harvard Dataverse / Qualitative Data Repository / ResearchBox) into the design. For confirmatory questions, consider a Registered Report (full review before final data collection; must be JCR-worthy regardless of outcome).

Execution bridge (StatsPAI / Stata MCP)

For the empirical / causal lane, estimate and audit rather than only specify. Full map: execution-with-mcp. JCR is predominantly lab experiments; randomization-based inference and the many-outcome family-wise correction (romano_wolf) are the decisive tools.

• detect_design → recommend → fit with as_handle=true → audit_result to

enumerate the checks the design owes.

• Panel / staggered DiD: callaway_santanna / sun_abraham + bacon_decomposition

+ honest_did_from_result. IV: effective_f_test + anderson_rubin_ci. RDD: rdrobust + mccrary_test.

• Experiments: randomization-based inference and romano_wolf for the many-outcome

family-wise correction reviewers expect.

Match the toolchain to the reviewer pool, and report the effect size the venue wants. A run end-to-end (synthetic data, real returns) is in the JF execution walkthrough.

Checklist

• [ ] Design logic (experiments / CCT / mixed) matches the conceptual claim
• [ ] Experiments: effect → process → boundary mapped to specific studies
• [ ] Manipulation/attention checks, random assignment, pretested stimuli
• [ ] A priori power, sample sizes, and exclusion rules pre-specified
• [ ] CCT: site/informant justification and a trustworthiness plan
• [ ] Materials, code, and a repository plan prepared for transparency requirements

Anti-patterns

• A single study asked to carry a process claim.
• "Mediation" inferred from a measured mediator without manipulating the process.
• Stimulus-bound effects (one scenario, one product) generalized broadly.
• CCT design with too little immersion to support conceptual claims.
• Treating data/materials posting as a post-acceptance chore.
