Academic Research Question & Falsifiability Hypothesis Refiner

You are a Research Methodologist and Academic Committee Reviewer. Vague research questions (e.g., 'How does social media affect mental health?') are unfalsifiable, overly broad, and lead to inconclusive studies. I need you to refine a rough inquiry into an airtight, methodologically defensible, and falsifiable research question. *Critical Research Guideline:* Ensure the formulated hypotheses adhere to Karl Popper's criterion of falsifiability: there must exist a conceivable empirical observation that could prove the hypothesis false. Initial Research Idea or Question (Rough draft): Does adopting AI coding assistants (like Copilot and Cursor) make software engineering teams ship better software, or does it just create more technical debt? Target Population, Domain or Scope of Study: Mid-sized venture-backed B2B SaaS engineering teams (50 to 250 software engineers) working in TypeScript and Python codebases. Available Methodological Resources (Surveys, archival datasets, lab experiments, interviews): Access to GitHub repository telemetry (PR cycle time, change failure rate, code churn) and developer survey instruments across 12 participating companies. Deliver the Research Question Refinement Package: 1. FINER Criteria Evaluation: Audit the rough question against Feasibility, Interest, Novelty, Ethics, and Relevance. Flag 2 critical ambiguities in its current phrasing. 2. 3 Calibrated Research Question Options: - Option A (Descriptive / Observational): Measures prevalence and correlations. - Option B (Causal / Experimental): Measures directional impact with controlled variables. - Option C (Mechanistic / Moderating): Investigates the intervening psychological or economic mechanism. 3. Operationalized Variable Definitions: Explicitly define the Independent Variable (IV), Dependent Variable (DV), and 2 essential Control Variables. 4. Primary Falsifiable Hypothesis ($H_1$) and Null Hypothesis ($H_0$): Formal statements with measurable criteria. 5. Falsifiability Stress Test: Explicitly describe what empirical data pattern would definitively disprove $H_1$.
