A JCP contribution sentence has a specific shape: "We show that [antecedent] shapes [consumer outcome] because it [changes psychological state M], which means [implication / new boundary / overturned belief]." The "because" clause is the contribution. If your sentence stops at the comma after the outcome, you have an effect, and an effect alone is a reject. The framing job is to make the mechanism the headline and the effect merely the vehicle that reveals it.
The second JCP requirement is theoretical surprise or correction: the process should change what a knowledgeable reader expected — a non-obvious mediator, a reversal under a predicted condition, a reconciliation of conflicting accounts. "Confirms intuition" is not a JCP contribution; "explains why the intuitive account is wrong" is.
| Framing | Template | When to use |
|---|---|---|
| Novel mechanism | "Effect E runs through unexpected process M, not the assumed P" | The effect is known but mis-attributed |
| Theory-test moderation | "Because the effect runs through M, it reverses when C blocks M" | You have strong moderation-of-process data |
| Reconciliation | "Conflicting findings F1/F2 are reconciled once M is recognized" | Two literatures disagree and your process resolves it |
Whichever you pick, lead with the mental process and the consumer stake in the same breath; JCP wants both theoretical interest and consumer relevance, but the process is primary.
【Contribution sentence】"…because it [process M]…" (one line, process-led)
【Why non-obvious】what informed reader belief it corrects/surprises
【Backing study】the strongest process design that supports it
【Scope bound】populations/stimuli the claim is limited to
【Consumer stake】one line of relevance (subordinate to the process)
