In response to wrongful convictions, there has been a revolution in criminal procedure and research in law and science. This review seeks to summarize the cross-disciplinary explosion in work studying known wrongful convictions, examining their causes, and assessing policy reforms designed to help detect and prevent errors in criminal justice. Scholars have increasingly studied the characteristics of known wrongful-conviction cases, including by analyzing archival records and by creating public registries of exonerations. Scholars have conducted research in law, psychology, statistics, criminology, and other disciplines, as well as interdisciplinary research, designed to better understand the phenomenon of wrongful convictions and how to prevent errors. Scientific bodies, such as the National Academy of Sciences, have made important recommendations based on this research. Furthermore, the conversation is global, with litigation, research, and policy work across jurisdictions. A wide range of jurisdictions have adopted noteworthy changes designed to safeguard crucial types of evidence, such as confession, forensic, and eyewitness evidence, during police investigations and at trial. As a result, law and science have increasingly come together to produce tangible improvements to criminal justice.
