David: I just wanted to point out that it’s possible, at least in theory, for sexual harassment to be both underreported and overreported — that is, many real incidents may go unreported, even while many non-incidents result in filed complaints.

As for whether sexual harassment actually is underreported in addition to being (as you document) overreported, it’s hard to tell. Lots of sources claim it is, but they always use some ridiculous standard based on how the alleged victim “felt.”
