This kind of shit was so common before the Internet. Encyclopedias would have completely wrong information or would cite just one source that was outdated.
My contribution is meaningful. Men "commit" more crimes because they're convicted of more crimes. There are MANY studies across centuries that look into that.
It's not possible to measure committed crimes. If anyone parrots some crime statistics without limiting themselves to violent crimes it's 100% bullshit. Crime statistics just measure convictions. Violent crime rates often times include unsolved murders and assaults.
Random bulk rate books aren't artifacts. The vast majority of them probably have a copy in Anna's Archive.
