Marriage and Rape are basically the same thing for differing lengths of time

The just-world phenomenon, also called the just-world theory, just-world effect or just-world hypothesis, refers to the tendency for people to believe that the world is "just" and so therefore people "get what they deserve."

In another study, subjects were told two versions of a story about an interaction between a woman and a man. Both variations were exactly the same, except at the very end the man raped the woman in one and in the other he proposed marriage. In both conditions, subjects viewed the woman's (identical) actions as inevitably leading to the (very different) results.
