One alternative (which appears to work with alcohol problem drinking) is to tell people what other people like them are doing. Thus, all the newspapers and tv programmes talking about the perils of binge drinking and how everyone is drinking too much and how it's harmful to them and the nation - that just makes people think that excessive drinking is just what people do. But if you tell university students that people their age tend to drink about 8 units a week (or whatever the actual real average is) then they realise that they drink a lot more than that and start to cut down.
Telling men that "most men think drunk consent is not consent" would be in line with this, and is I think what the article is talking about.
I remember those binge drinking proclamations in college and reading a few years later that they basically didn't work at all. People construct their social norms based on the behavior of those they observe around them, and particularly the people they care most about: their friends and their friends' friends, not some vague model citizen they were told about in some quasi-propagandist fashion. And if I recall the article correctly, the average they quoted wasn't even real, so in effect it was propaganda.
