Clear communication through clear purpose: understanding statistical statements made by forensic scientists

Abstract

Based on a plenary lecture presented at the 50th Anniversary of the Australian Academy of Forensic Sciences Symposium (November 2017) this article reviews the literature relating to the communication of forensic science evidence using statistical statements. Five dimensions of communication are identified: consistency, sensitivity, coherence, ability and orthodoxy. The review also considers the strengths and weaknesses of lay comprehension as well as opportunities for improving understanding through reflection and collaboration.
