The current chapter discusses rape myths, rape myth acceptance (RMA), and the potential for such myths to change over time. Rape myths regarding heterosexual and non-heterosexual victims of sexual violence are considered, as well as relevant factors that could influence the extent to which individuals endorse particular rape myths. The content and expression of RMA are discussed in relation to the changing nature of rape myths. Given such changes over time, and a particular lack of research regarding non-heterosexual and child victims, current measures of RMA are limited. As such, the current chapter reviews and critiques popular measures and argues for the expansion of these measures to include heterosexual male, LGBTQ+, and child victims. Next, the connection between RMA and legal outcomes for female, male, and LGBTQ+ victims is reviewed. The chapter concludes with a call for future research to examine novel and/or more inclusive measures of RMA; rape myths regarding child victims; and a deeper investigation of RMA among non-juror legal actors, including law enforcement officers, attorneys, and judges.
