I think both have the same root cause: not ignorance but laziness. Bad HR people tasked with filtering resumes don't want to hire the best people, they want to do as little work (and as little thinking) as possible while appearing to do a useful job. So they just love rules that filter a lot of resumes, can be applied without thinking and make superficial sense. Understanding how skills relate is more work than comparing lists, looking at the specifics of a criminal conviction is more work that just using it as a binary exclusion criterium.
