Theory & Hypotheses (joap-theory-and-hypotheses)
JAP is theory-first. A paper lives or dies on whether it makes a theoretical contribution to I-O
science — a new mechanism, boundary condition, integration of frameworks, or construct
clarification — and whether the hypotheses follow from that theory. The cardinal honesty rule:
state theory and confirmatory hypotheses before the data, and label anything generated after seeing
data as exploratory.
When to trigger
- Building the theoretical model and deriving hypotheses
- Writing a preregistration / pre-analysis plan
- Reconciling what you predicted with what you found
- A reviewer flagged the work as "atheoretical," "post hoc," "HARKed," or "no contribution"
Build the argument
- Name the mechanism. What process links X to Y, and why — grounded in I-O theory (e.g., social
exchange, conservation of resources, self-determination, JD-R, affective events, justice). The
mechanism is the contribution's core, not decoration.
- Specify the level(s). State whether each construct and relationship is at the individual, dyad,
team, or organization level, and whether effects are cross-level (e.g., 1-1-1, 2-1-1, 2-2-1). JAP
reviewers read level-of-analysis sloppiness as a theory error.
- Derive directional hypotheses. Translate the theory into specific, signed, testable predictions;
state mediation and moderation as formal hypotheses, not afterthoughts.
- Mark hypothesis status. Separate confirmatory (preregistered / predicted in advance) from
exploratory (post hoc) analyses, clearly, in the text.
- Specify what would disconfirm. Say which results count against the theory — this is what makes
the test, and the contribution, credible.
What counts as a JAP theoretical contribution
| Contribution type |
What it must show |
| New mechanism |
a process not previously specified linking established constructs |
| Boundary condition |
when/for whom a known effect holds or reverses (a theorized moderator) |
| Integration |
two frameworks reconciled to predict something neither does alone |
| Construct work |
a clarified, differentiated, or newly measured construct with validity evidence |
| Cross-level model |
how a higher-level factor shapes lower-level processes (or emergence upward) |
Worked micro-example — theory to hypothesis status (illustrative)
A servant-leadership package, written so the mechanism, levels, and hypothesis status are legible.
Mechanism: Servant leadership signals safety and worth, building team
psychological safety (social-exchange + safety climate), which
frees members to voice and coordinate, raising team performance.
Levels: Leadership (team, L2) → psychological safety (team, L2) →
performance (team, L2); voice tested as L1 mediator (2-2-2 / 2-1-2).
H1 (confirmatory): Servant leadership relates positively to team performance.
H2 (confirmatory): Team psychological safety mediates H1.
H3 (confirmatory, preregistered in the lab study):
The effect is stronger under high task interdependence (boundary).
Disconfirming: a near-zero indirect effect with a CI spanning zero, or a
reversed safety path, counts against the account — stated up front.
Theory-stage reviewer pushback and the venue fix
| Reviewer pushback |
JAP fix |
| "No theoretical contribution" |
name the new mechanism/boundary/integration in one sentence before H1 |
| "Level of analysis is muddled" |
label every construct's level and the cross-level form (1-1-1, 2-1-1, …) |
| "This looks HARKed" |
show the preregistration timestamp; relabel post hoc analyses exploratory |
| "Hypotheses don't follow from the theory" |
rebuild each H as a signed deduction from the stated mechanism |
| "Mediation/moderation asserted, not theorized" |
give the process reason the indirect/interaction effect should exist |
Theory calibration anchors
- The contribution is the mechanism and its boundary, not the data context — "we tested it in
hospitals" is a setting, not a theory advance.
- Level of analysis is theory, not bookkeeping: a cross-level claim needs a cross-level model and a
cross-level hypothesis, stated as such.
- The honesty rule is temporal: anything specified before data is confirmatory; anything generated
after seeing data is exploratory. Preregistration and the data-transparency appendix make the line
visible to masked reviewers.
- Stating what would disconfirm the theory converts a story into a test; an unfalsifiable framing
reads as a red flag at JAP.
Anti-patterns
- A "contribution" that is only a new sample/industry for a known effect
- Muddled or unstated level of analysis
- Mediation/moderation hypotheses with no theorized process behind them
- Theory written to fit the result after the fact (HARKing)
- Blurring confirmatory and exploratory hypotheses
