Most, if not all, of Erdely's story might still hold up. But even if the story turns out to be 98 percent right, this whole episode is terrible news for survivors of rape on college campuses and elsewhere.

Let's be clear about one thing. Fraudulent accusations of rape are extraordinarily rare. This graph proves it. pic.twitter.com/mX7xPHvMkZ — Terrence McCoy (@terrence_mccoy) December 5, 2014

Several major magazines have published “campus rape” stories in recent months, but Erdely’s was by far the most high-profile. It was posted on my Facebook feed repeatedly, all by different friends. It launched countless Internet “takes.” Most importantly, it prompted a major investigation at UVA and led to the suspending of all of the school’s fraternities. In terms of impact factor, this is a journalist’s—and a sexual-assault-prevention advocate’s—fantasy scenario.

Phi Kappa Psi now says that it does not have a member by the description Jackie provided in the magazine, and that the group did not host a party on the night she claimed the incident took place. Even some of Jackie’s former supporters told the Post they “feel misled.” After she told a group of friends the attacker's name this week, the Washington Post determined that a man by that name is not a member of Phi Kappa Psi.

Some of Erdely’s critics say she should have made a greater effort to interview the accused men. I agree, but I can also understand Erdely’s dilemma. As someone who frequently covers sexual health, I know how hard it can be to entice sources to talk on the record about their personal lives, especially when what supposedly occurred was a monstrous crime. Thus the fake names and absence of the “declined to comment” disclaimer in the Rolling Stone piece.

Erdely bartered the chance to seek out the alleged rapists in exchange for a truly earth-shaking and, she hoped, honest account from a survivor. Let’s say Jackie is telling the truth. The alternative to this story was not “this exact story, but with a comment from the alleged rapist.” The alternative might have been no story at all. The reason we so rarely hear about the full extent of the campus-rape problem is that the crime is so secretive, stigmatized, and difficult to verify. That’s particularly true in cases like this one, where there’s no campus or police paper-trail backing anything up.

Rape stories, meanwhile, are a genre that’s uniquely unforgiving of inaccuracies. Universities and fraternities could use an inconsistent story as an excuse to move on to other issues and to downplay their assault problems. Anti-feminists brandish wrongful accusations in order to claim that “most” rape victims are liars. Victims, meanwhile, become even more skittish, understandably wishing to spare themselves the same scrutiny and persecution. The overwhelming majority of rapes are never reported, in part because many victims fear they won’t be believed.
