RMP.2:11 - SoTA-Echoing

The working question is: How should a practitioner choose among unlike research designs—or stop—so that the selected strategy bears on the live criticism and no missing load-bearing result is concealed?

The selected current line is design-plural and uncertainty-led. The MRC/NIHR framework for developing and evaluating complex interventions selects among efficacy, effectiveness, theory-based, and systems perspectives from what is already known, which uncertainty matters, and what evidence would be most useful; its phases can be entered, revisited, repeated, or stopped rather than treated as one compulsory sequence. RMP.2 generalizes that selection discipline without importing health-intervention phases into every domain.

Unlike source families constrain criticism differently. The Standards for Reporting Qualitative Research emphasize transparent qualitative reporting while preserving flexibility across paradigms and methods; RMP.2 uses them as a warning that reporting completeness is not design selection. The American Historical Association’s Statement on Standards of Professional Conduct foregrounds careful source use, methods and assumptions, evidence-interpretation relations, bias awareness, and alternative interpretations in historical work. The current Cochrane Handbook makes the review question govern eligibility, search, collection, and synthesis rather than treating “review” as a carrier label. The National Academies’ Reproducibility and Replicability in Science keeps computational reproduction and new-data replication distinct, supporting threat-specific credibility choices rather than one repeatability ladder.

A serious alternative is a universal evidence hierarchy or linear “scientific method”: choose the highest-ranked feasible design, operationalize it, collect data, and report. That route can be efficient for a narrow recurring question, but as a universal selector it suppresses historical source criticism, qualitative reflexivity, observational constraints, model validation, corpus synthesis, and legitimate stops. RMP.2 retains domain hierarchies only when a qualified domain use makes them decision-bearing and compares their actual criticism and losses.

The selected sources do not supply domain truth, universal validity criteria, instrument feasibility, rights, access, safety, ethics, or authority. Reopen this pattern when a stronger design-selection source changes the serious families or criticism relation, when a family is systematically misrouted by the counterfactual test, or when a domain-specific evidence rule changes one candidate. Reopen only the affected comparison and disposition.
