She goes into it a bit here: https://aella.substack.com/p/my-kink-survey-design-methodology?s=w https://aella.substack.com/p/my-kink-survey-design-methodolo... but one key bit from it is here (this is quoted on the linked page, from the survey itself: “Our sexual fantasies are different from what we do in real life. I'm going to ask about some things that might seem cruel if actually done; being aroused by a taboo erotic fantasy does /not/ mean you would violate consent in real life. Please answer according to your ideal fantasies, even if you would never actually act on it.” (slightly later) "A good test is "have you searched porn of this thing", "have you masturbated to fantasies about this thing", or "have you asked a sexual partner to participate in this thing" So someone who has masturbated to fantasies involving orgies or animals or execution would likely be included.
