# Theory Development, Phenomenon-First (jm-theory-development)

## When to trigger

- The phenomenon and question are set; you need a defensible conceptual argument
- Reviewers will ask "why does this happen?" and "what is the mechanism?"
- You have a strong empirical pattern but no organizing logic (empirics-first)
- You are tempted to bolt a generic theory onto a marketing finding

## JM's theory stance: serve the substantive question

Unlike theory-first flagships, JM does not reward theoretical machinery for its own sake. Its bar is **substantive insight into a real marketing question**. Theory in a JM paper earns its place by **explaining a consequential marketing phenomenon** and yielding predictions that, when tested, change how managers, policy makers, or society understand the market. The official editorial guidelines frame JM as a bridge between scholarly and practical stakes, so build the *minimum sufficient* conceptual structure that makes the phenomenon intelligible and the predictions sharp.

## Two legitimate routes into JM

1. **Theory-first**: a clear mechanism generates predictions, then data test them. Standard, accepted.
2. **Empirics-first**: a robust, surprising real-world pattern leads, and the conceptual account is developed to explain *why* it occurs. JM actively solicits empirics-first work (dedicated special issue and editorials) grounded in real-world phenomena. This is encouraged here in a way that is unusual among top journals — but the pattern must still be explained, not merely reported.

Decide which route you are on and signal it honestly; do not disguise an empirics-first paper as theory-first (a HARKing risk).

## Build the conceptual logic

- **Anchor in the phenomenon**: state the marketing fact the theory must explain (e.g., why a pricing, advertising, channel, or brand move produces an unexpected market response).
- **Specify the mechanism**: the process linking marketing action/condition to the consequential outcome. Name boundary conditions (when it holds, when it reverses).
- **Derive predictions** at the level you can measure (consumer, segment, brand, firm, market) and that map to outcomes managers/policy makers care about.
- **Moderation/mediation**: predict the *process* and the *contingencies*, not just a main effect, so the substantive story is mechanism-rich.
- **Managerial logic**: carry the implication through — if the mechanism holds, what should a decision maker do differently?

## Checklist

- [ ] The phenomenon the theory must explain is stated explicitly
- [ ] Route declared (theory-first vs. empirics-first) and handled honestly
- [ ] Mechanism named, with boundary conditions
- [ ] Predictions at a measurable level, tied to consequential outcomes
- [ ] Moderators/mediators predicted, not just a main effect
- [ ] Managerial/policy/societal implication of the mechanism articulated
- [ ] Conceptual structure is as simple as the substantive insight allows

## Anti-patterns

- **Theory theater**: elaborate framework that adds no substantive insight.
- **HARKing**: presenting post-hoc explanations of an empirics-first pattern as a priori theory.
- **Main-effect-only logic**: no mechanism, no contingencies.
- **Borrowed-theory veneer**: a generic psychological/economic theory pasted on without fit to the marketing phenomenon.
- **Mechanism with no managerial consequence**: process that no decision maker can act on.
