Now introduce one piece of information; fewer than half of all rape accusations are false. This is a very modest assumption; while Kanin put the rate of false accusations at 41%, most sources put it lower. Feminists, unsurprisingly but in the absence of any real backing, claim false accusations are virtually non-existent. In any case, let's just say, statistically, more accusations are true than false.
With this one piece of extra evidence, we change the probabilities. A man accused of rape is more likely to be guilty than innocent.
But with the 'preponderance of evidence' standard now enforced by Obama's Department of Education, a better than 50% probability of guilt is sufficient to convict. That means, going into a campus sexual assault hearing, if no evidence at all is presented against him, the man should (according to the rules) be convicted.
Facing nothing but an accusation, therefore, he bears the burden of proving himself innocent, turning the entire common law tradition of Anglo-American jurisprudence on its head.
