Is there any research into the sorts of people who use "sex robots" which we don't already know about? A fair bit of this science seems to come from forensic psychologists (psychologists who work with criminals, i.e. Dr. Harper), and that is probably not terribly representative of a group (and looks at people a lot through the lens of whether they "might commit a crime"). It can be a lot like figuring out what sort of people play video games by interviewing someone in a prison.

Preferably, not empty philosophical musings about how they are "wrong", "I heard a random cop claim this", conspiracism, or reaching. That is not research.
