Making evidence useful at the point of decision

Evidence and context

Publishing a finding creates an opportunity for it to be used. Whether it reaches a person facing a relevant decision is another question.

Hjort and colleagues conducted experiments involving 2,150 Brazilian municipalities. In one experiment, providing mayors with research about taxpayer reminder letters increased adoption of that policy by ten percentage points. The study demonstrates an effect for a particular information intervention and policy decision, not a universal conversion rate from research to action. American Economic Review, 2021

Those are different information needs. A useful record should help each reader reach the relevant evidence without disguising the uncertainty around it.

An illustrative scenario is a team reconsidering a delivery model. The most useful view might bring together the original assumption, implementation experience, participant feedback, costs and the options still available. A large collection of loosely related documents would require another layer of work before it could serve that decision.

For a pilot, that suggests looking beyond records created or searches completed. Ask whether the evidence reached a real decision and whether the user could understand its relevance and limits.

Implications for research and practice

Evidence availability and evidence use are distinct outcomes. Research dissemination should be evaluated against decisions rather than publication counts alone.

Scope and limitations

This is a selective narrative brief based on the linked publications, not a systematic review or a new empirical study. Illustrative scenarios and practice implications are editorial analysis. Findings should be interpreted within the settings, methods and observation periods of their original sources.
