Evidence use across policy sectors is widely believed to vary as each sector espouses a specific and dominant pattern in how it sources evidence. This view privileges the idea that a “culture of evidence” serves as a norm that guides behavior in the entire sector. In this article, we seek to nuance the policy sectoral approach to understanding evidence use by analyzing the results of a large-N survey of federal employees in Brazil (n = 2,177). Our findings show a diverse set of cultures of evidence with a few sectors like Science and Technology demonstrating a strong likelihood for using scientific evidence with most sectors showing a mixed pattern of sourcing evidence. However, a majority of the surveyed civil servants show an “indistinct” pattern of evidence use who are likely to not use any sources of evidence.

不同政策部门的证据使用差异：巴西的案例


人们普遍认为，政策部门的证据使用各不相同，因为每个部门在如何获取证据方面都支持特定和主导的模式。这种观点认为，“证据文化”是指导整个行业行为的规范。在本文中，我们试图通过分析对巴西联邦雇员 （n = 2,177） 的大型 N 调查结果，对理解证据使用的政策部门方法进行细微差别。我们的研究结果显示了一组不同的证据文化，其中科学和技术等少数行业表现出使用科学证据的可能性很大，而大多数行业显示出混合的证据来源模式。然而，大多数受访公务员表现出“模糊不清”的证据使用模式，他们很可能不会使用任何证据来源。
