For example, educational programs sound as a rational idea until you look at older studies that looked at the effect of increasing the punishment for crime. As I recall there were no effect for most form of violence, including sexual violence, with the researchers conclusion that much crime don't follow rational planning. If the criminal don't do a risk vs reward analysis before the crime, then increasing the punishment won't have an effect on the thought processes. Similar education and work sponsored events is unlikely to help if the action is irrational and involve a lot of self-delusions.
I can see how mores lights and banning hard alcohol can work. People have a emotional reaction to light, and drugs/alcohol operate on the part of the brain that handles social interaction and inhibitions.
The problem is the methods that are most likely to be effective are considered victim blaming.
E.g. Teaching women how to directly and clearly say no.
Or making it socially inappropriate to get blind drunk.
Etc etc.
As a thought experiment, you can imagine a world where courts are required to give instructions to the jury, telling them that they must always treat an alleged victim's testimony as a 100% accurate representation of the incident. That would make most sexual assault cases slam dunk. And it'd result in more guilty rapists being convicted, and very likely more of them than the number of innocent people falsely accused of rape.
Is that an appropriate use of institutions of justice? I don't think so. And it wouldn't be sustainable, as it'd weaponize accusations in a way that they're not now: you'd rapidly see people abusing it, and see a huge backlash.
But there's not an alternative justice-wise to that, which is why attentions are turned to other institutions that can only offer a slap on the wrist, but a slap on the wrist that can be based on very little evidence. No one is really happy with that reality, but no one has any better ideas.
That's why an epidemiological approach--running tests on everything from lights, to educational programs, to banning hard alcohol at school or work sponsored events--seems like the best way out of this hole to me.
