name: jop-theory-building description: Use when turning a The Journal of Politics (JOP) idea into a theoretically innovative argument — formal/game-theoretic, empirical, or normative. JOP explicitly prizes theoretical innovation across all subfields and counts pages, so the argument must be sharp, general, and economical. Builds the argument; it does not run analyses.

Theory & Argument Building (jop-theory-building)

JOP advertises that it publishes theoretically innovative work and treats theory broadly — formal, empirical, interpretive, and normative all qualify. This skill turns your idea into an argument a general reader recognizes as new, and tight enough to fit the page budget.

When to trigger

• Moving from "interesting finding" to "argument that contributes"
• Specifying mechanisms, assumptions, and observable implications
• A reviewer said the theory is "thin," "post hoc," or "not novel"
• Linking a formal model to its empirical or substantive test

Build the argument (mode-aware)

Empirical / mechanism-based

• State the mechanism: what causes what, through what channel, under what scope conditions.
• Derive observable implications that could be wrong — the argument must be falsifiable.
• Separate predictions unique to your account from those shared with rivals (sets up jop-research-design).

Formal / game-theoretic

• State primitives, equilibrium concept, and the comparative statics that carry the substance.
• Make the model earn its place: what does formalization reveal that prose could not?
• Pair it with an interpretable empirical or substantive payoff — JOP is general-interest, not a methods outlet.

Normative / interpretive

• State the conceptual claim and the stakes; make the argument's structure explicit and contestable.
• Engage the strongest opposing position rather than a strawman.
• Show why the normative stakes matter for empirical politics or public life.

The JOP innovation test

Write one sentence: "Before this paper the field thought ___; this argument shows ___, which matters to readers beyond my subfield because ___." If the first blank is "no one had estimated this in case X," the contribution is probably incremental for a general journal.

Worked micro-example (illustrative)

A hypothetical project finds legislators co-sponsor more bills after office moves put them near ideological opposites. Stated as a finding, it is a correlation. As a JOP argument it names a mechanism — physical proximity lowers the cost of cross-party information exchange, raising co-sponsorship under the scope condition of low electoral risk — and yields an implication that could be wrong, unique to the proximity account and not shared by a pure homophily rival. That falsifiable contrast is what makes the argument contribute rather than describe.

Referee pushback patterns and the JOP fix

• "The theory is thin — this is a list of expected signs." Name the mechanism (what acts on what, through what channel, under what scope) and derive at least one implication that could fail.
• "The formal model has no payoff here." Pair the comparative statics with an interpretable empirical or substantive consequence; JOP is general-interest, not a methods outlet.

Keep it economical (page budget)

• A general reader needs the logic, not every contingency — state the core argument cleanly.
• Long proofs, derivations, and auxiliary results go in the Online Appendix (≤ 25 pp).
• Hypotheses should be few and load-bearing; a wall of H1–H12 wastes pages and dilutes the contribution.

Anti-patterns

• A "theory" that is really a list of expected signs with no mechanism
• A formal model with no empirical or substantive payoff in a general-interest venue
• Hypotheses unconnected to the eventual test (see jop-research-design)
• Theory so elaborate it cannot be developed and tested within the page budget

Operating pass for Journal of Politics

Treat this skill as an executable review pass, not a prose hint. First lock the political mechanism, evidence design, and scope condition; then judge whether the current manuscript answers the venue's real reader: political-science reviewers who want theory, identification or formal logic, and generalizable political implications in balance.

• Do the pass: Return a claim-evidence-risk ledger rather than a prose-only diagnosis; every recommendation must point to a manuscript location or missing artifact.
• Return a ledger: give claim / evidence / risk / manuscript location rows, so the next agent can edit rather than rediscover the issue.
• Sibling guard: compare against APSR for field-wide political science, AJPS for design-heavy empirical work, World Politics for comparative/international politics; if a sibling owns the contribution, recommend re-routing before polishing format.
• Stop condition: do not give submission-ready advice until the pack's resources/official-source-map.md has been checked for volatile rules and the manuscript has one concrete fix for the largest venue-specific risk.
