For instance, consider Yager’s analysis of a 2010 study titled “False Allegations of Sexual Assault: An Analysis of Ten Years of Reported Cases.” The study is one of the few to examine false reports with specific reference to campus allegations, and is frequently cited by government officials and activists. David Lisak, a former associate professor of psychology at UMass Boston and a prominent consultant on campus sexual assault, is the lead author; when he and his co-authors reviewed the reports of sexual assault at one northeastern university to determine what percentage were false, they concluded that the figure was not quite 6 percent. “Over 90 percent of reports of rape are not fabrications. They’re not false allegations,” he said in a videotaped interview describing the research.
Yager writes, however, that about 45 percent of the cases Lisak reviewed did not proceed, because there was insufficient evidence, or the complainant withdrew from the process or couldn’t identify the perpetrator, or the allegation did not rise to the level of a sexual assault. In other words, no one could possibly determine whether these claims were true or false.
