We know rape is statistically a problem and we know it isn't well-studied. We are scientists. The next thing to do is not to listen to panic and get reactionary, it is to dedicate the resources necessary to pursue a proper understanding of it.
We're also engineers and entrepreneurs. I'd like to think we know well enough that to start with the lowest hanging fruit when trying to make positive change.
These are the reasons I'm not really ready to march in here with a "how to fix rape: the article." I would be really excited to see what other people have written as far as possible solutions to this. I'm trying to read through scholarly criminology journals when I have time. They're doing some good work. I wish more smart people were paying attention.
In the meanwhile, what I am for sure is needed is for people to look out a little bit for each other, so if there is somebody in your life who has reason to feel afraid and alone (or afraid of being alone), they know they aren't going to be.
