This is interesting to me largely because it intersects with one of my long-term "huh, I wonder how to follow up on THAT" questions about sexual assault, WHICH IS that in "Repeat Rape and Multiple Offending Among Undetected Rapists" (Lisak and Miller, 2002) about 1/3 of "undetected rapists" commit only one rape. I've always been curious about WHY. What happens that they stop, when the other 2/3 of undetected rapists continue? They didn't get caught, so it's not that. The same paper looked at interpersonal acts of violence committed by non-rapists, single-act rapists, and repeat rapists, and single-act people were more violent than non-rapists but WAY, WAY less violent than repeaters. WHY.

A big part of the reason that I'm curious is that I wonder if that segment of the rapist population is...educable? Ideally BEFORE they commit a rape and/or other acts of violence? Knowing why they stopped at one could indicate an effective intervention for the future. But as near as I can find out no one has ever figured this out (or tried to).
