In Chapter 10, Krakauer begins to delve more deeply into academic research on acquaintance rape. This research tries to answer key questions about rape and rapists by examining statistical and clinical data. What the data shows is that most rape occurs between people who know each other and that the only clear thing that clearly distinguishes rapists from the rest of a population is the act of rape. Rapists do tend, however, to have narcissistic personality traits. The “Frank” video interview demonstrates that. Lisak’s clinical interviews show that rapists are sometimes unaware that the acts they commit against unconscious or defenseless victims are rapes. This suggests that better educating young men about rape and better promoting awareness of and empathy for rape victims might help to prevent rape from taking place. Likewise, the chapter argues that law enforcement officials and prosecutors need to be better educated about just how “normal” rapists can seem. If law enforcement does not learn to recognize that “normal” people may, in fact, be violent criminals, than rapists will continue to get away with their crimes.
