DecisionSource and target relationshipEvidence still neededHonest result
ReplicationPopulation, treatment, outcome, and context are intended to remain the same, with a new observation or sampleRepeat the source design and check whether the result recursThe source result was reproduced or not reproduced
TransportAt least one target field is intentionally differentA bridge through target data, measured effect modifiers, designed variation, or a new target studyThe target inference is supported, limited, or unresolved
AnalogyA product, market, or mechanism merely sounds similarA matched comparison has not been suppliedA hypothesis or prior, not a transfer result
