What is Evidence?

Written By Shelley M

This brief explores the purposes and potential uses of evidence. It discusses what makes good evidence in federal policy and practice and argues that evidence is useful for three discrete but complementary purposes: 

  • Inform focus. Detect problems and inform where to focus attention and funding 

  • Find what works. Find what works, what works better, and the situational differences influencing effectiveness 

  • Spread what works. Increase use of better practices, and improve or reduce use of less effective or harmful ones

In addition, evidence can be useful for building understanding of and trust in government.
