There is discussion all over the internet about Sulcowicz carrying her mattress to shame ex-friend Nungesser who she calls rapist. I had enough of it quickly, but thought that a discussion over at Grim's Hall, might be worth it, but it attempts to go into men's perceptions versus women's perceptions of such events, which is way out ahead of the data.
Well, that is an interesting subject, just as fraternity attitudes leading to rape culture, with reference to Rolling Stone's reporting of what happened at UVA is an interesting subject. The problem is, we don't know whether there is any grounding in fact of any of the events.
The most likely scenario is that either Sulcowicz or Nungesser is mostly lying about what happened, not that they have different perspectives. Similarly, the most likely UVA reality at this point is that the accuser was lying, because there are no supporting bits of evidence and many which contradict her. That UVA fraternity guys may be jerks or even rapey may be true, but no longer has anything to do with this story. In another setting, I might say the evidence leans toward an accuser even though she can't prove it.
But right now, there isn't evidence. Nor does it look like there will be any. See my post Fanatics about a half-year ago.
Update: Megan McArdle compared this to the recovered-memory and Satanic-ritual-abuse witch hunts 20-30 years ago, and that shook me deeply. All mycommenting on the new drawing of lines (mostly among the young, who do not remember those horrors and seek to change their own immediate culture) will be influenced by that. I cannot recall any statement of mine which encouraged that evil in the 80's, but I certainly said little against it, and did not oppose it.
Plus, I may have conveniently forgotten some evil that I did do.
