This report reviews advances in research and in our criminal legal system since the release of the 2014 NAS report. We base our findings on a systematic scoping review of empirical research in eyewitness identification, a workshop with researchers and legal professionals (November 2020), and surveys of leading respondents, as described below. This report also offers promising future directions for both research and practice. The NAS report encouraged research in new directions leading to new developments in the field, and we describe them here.
