Kahneman and Klein (2009) argue that two factors are required for skilled intuition—(1) an environment of high-validity, and (2) adequate opportunity to practice. By high-validity they mean an environment that is sufficiently regular in terms of the relationship between cues and events or the outcomes of actions to be predictable. Kahneman and Klein argue that if the environment provides good feedback and valid clues, individuals who have sufficient talent will eventually develop expert intuition and skill. High-validity in the context of rape would be situations in which an offender could reliably anticipate victim response, bystander presence, and other factors related to the successful completion of their offense. Clearly, certain types of rape may increase the validity of the environment. For example, marital rape occurring in the home with a well-known victim may have higher validity than date rape, which in turn would have higher validity than a stranger rape committed in public.
