Theory & Argument Building (crim-theory-building)

At Criminology a result is not a contribution until it is attached to a mechanism the field can use elsewhere. This skill turns crime findings into theory: explicit causal stories, scope conditions, and observable implications drawn from (or pushing against) the field's theoretical traditions.

When to trigger

• The empirics are strong but the "so what / why does crime behave this way" is thin
• A reviewer said the paper is "atheoretical," "ad hoc," or "just a finding"
• You need to state mechanisms, assumptions, and scope conditions explicitly
• You are extending or adjudicating between two criminological theories

Build the argument

1. Concept. Define the key constructs precisely — offending vs. arrest, desistance vs. a lull, victimization vs. reporting, legitimacy vs. compliance. Distinguish each from its neighbors.
2. Mechanism. The causal story: who does what, why, under what incentives, controls, opportunities, or strains. Make it a process, not a regression coefficient.
3. Observable implications. What we should see if the mechanism operates — and what we should not see. These become the tests in crim-research-design (e.g., a within-individual change in offending following a turning point; displacement vs. diffusion around a hot spot).
4. Scope conditions. Where the argument holds and where it does not — by age, offense type, developmental stage, place, or institutional context. Portability ≠ universality.

Engage the theoretical tradition (the Criminology move)

• Locate the argument in a recognizable theory (control, social learning, strain/GST, routine activity/opportunity, life-course/age-graded informal social control, labeling, deterrence, procedural justice, social disorganization/collective efficacy) — or say plainly how it revises one.
• Adjudicate where you can: state what your argument predicts that the leading rival theory does not, so the test in crim-research-design can separate them.
• Distinguish between- vs. within-person logics explicitly — many criminology theories live or die on whether the effect is a stable trait or a within-individual change.

The "portability" test (Criminology-specific)

Ask: Could a criminologist working on a different offense, age group, or setting import this mechanism? If yes, you have a field-level contribution. If it only works for your exact sample, tighten it into a general logic or reframe (back to crim-topic-selection).

Anti-patterns

• "Hypothesizing after results are known" (HARKing) — state theory before tests; preregister where possible
• Naming a theory in the intro but never deriving a testable implication from it
• Conflating between-person association with within-person change
• Universal claims with no scope conditions (e.g., "deterrence works") with no offense/context limits
• Burying the mechanism under the regression tables

What "engaging the theory" means to an ASC reviewer (calibration grid)

Criminology, the flagship of the American Society of Criminology, sits in a theory-testing tradition: a result earns the venue only when it does work on a theory. Reviewers grade engagement on a ladder. Aim for the top two rungs; the bottom two draw the "atheoretical / theory invoked, not tested" critique.

Worked vignette: from finding to mechanism (illustrative)

A study finds youth in high-collective-efficacy neighborhoods self-report about 25% less violence (illustrative). Decorative use stops there. The Criminology move: name the mechanism (informal social control — adults intervening on behavior), derive an observable a social-disorganization rival denies (the gap shrinks once residential stability is held within-neighborhood over time), and bound the scope (collective efficacy bites on expressive, not instrumental, crime). That converts a 25% correlation into a portable, testable claim.

Theory-side referee pushback (with the Criminology fix)

• "Theory invoked, not tested." Fix: derive one observable the theory implies and a rival denies.
• "Mechanism versus correlation." Fix: specify the behavioral process and within-person observable, not the coefficient sign.
• "No scope conditions." Fix: bound the claim by age, offense type, developmental stage, or place.

Output format

【Core claim】one sentence
【Tradition】theory engaged / extended / adjudicated
【Mechanism】the causal/behavioral story
【Observable implications】testable consequences (incl. within-person) → research-design
【Scope conditions】where it holds / fails (age, offense, place, context)
【Portability】who else in criminology can use this argument
【Next】crim-research-design
