Something else the "study" overlooks is a reported tendency of evangelical institutions to cover up "scandal" like sexual assault and suicide.

Just look at reports from former Liberty University students who claim that sexual assault has been pervasive on campus, but that university leaders do their best to stifle reports of such assaults, including pressuring students not to report them to the police.

I don't know how prevalent that sort of thing is at other conservative Christian schools, but any decent investigation would have to look at reporting artifacts, if the investigators want to be taken seriously.
