psci-theory-and-hypotheses

Use when stating the theory and hypotheses for a Psychological Science manuscript. The journal's credibility norms require a clear separation of confirmatory (preregistered) from exploratory analyses and theory stated before results. Structures the argument; it does not run analyses.

# Theory & Hypotheses (psci-theory-and-hypotheses)

Psychological Science rewards a **clear theoretical claim** and **honest hypothesis status**. Because
preregistration quality is weighed and a Research Transparency Statement is required, the cardinal
rule is: **state theory and confirmatory hypotheses before the data**, and label exploratory results
as exploratory.

## When to trigger

- Writing the theoretical framing and hypotheses
- Preparing a preregistration / pre-analysis plan (Registered Report or OSF)
- Reconciling what you predicted with what you found
- A reviewer flagged the work as "post hoc," "atheoretical," or "HARKed"
