The authors “sought to document knowledge, attitudes, and practices among a national sample of U.S. criminal justice leaders. In particular, we sought to understand the prevalence of innovation; the use of data and evidence to inform practice; the responses to disappointing results; and the barriers to widespread adoption of innovative practices” (p. 1). Six chapters follow an executive summary: introduction and methodology; respondent characteristics; prevalence of innovation; data-driven decision-making; barriers to innovation; and sources of new ideas. Fourty-six percent of respondents always use evidence-based decisionmaking, with 85% getting new information about criminal justice programs and/or reform initiatives from their colleagues.
