I had a sinking feeling you were going to say that. The scarcity of hard data on the point of how effective such things are is something of a shock to me. The study which Ephiral refers to is the only one I can find. Ephiral thinks the study is flawed, I think it is deeply flawed, but that does seem to be all we have.
I wonder how comprehensive the program was. I've seen more than my share of fights, fights between women usually are comprised of slapping and hair-pulling. Symbolic violence, very real but symbolic. Fights between men, well, men are more likely to seriously try to mess each other up, and more importantly, they are more likely to know how to do it. Women can be trained to seriously fight of course. I was, but training them out of symbolic violence into truly physically injurious violence takes time and effort. To a surprising degree for most women, we are just not culturally conditioned to react that way. I remembered how pleased my instructor was when the switch in my head finally flipped from "Stun" to "Kill" and I really started hammering at him.
If the results are widespread and turn out to be accurate... this bodes ill for any reeducation programs. If wanna-be rapists really are that insensitive to external inputs like the defensive behavior of their intended targets, how responsive will they be to the external influence of a reeducation program? Because to be truly effective, completing such a program has to offer a benefit to the subject, and where is the perceived benefit to the wanna-be rapists? Sure, a convicted rapist might habe to pass to meet one of the conditions for release, but what about future or uncaught rapists, why should they do more than go through the motions, what do they gain?
