Focusing on Uganda, the analysis argues that the conventional linear model of evidence-to-policy is conceptually inadequate because it overlooks the mediating mechanisms through which quantitative findings acquire institutional traction. Each mechanism is examined through a Ugandan policy domain, including budget reform, agricultural policy, and public sector management. The framework proposes that econometric evidence influences institutional resilience only when it is carried by identifiable actors, embedded in organisational routines, and aligned with prevailing political incentives. Methodological implications are drawn for the design of mixed-methods research in African settings, particularly the sequencing of quantitative and qualitative components. The article concludes that econometric practice in Africa must become institutionally literate, not merely technically proficient, if its outputs are to contribute to the resilience of public institutions.
