I happen to be reading the Silence of the Lambs book now, and I would put Clarice in Mind, with Subconcious as her concern. I’d put OS in Physics…all the forensic work, running around chasing down leads, the officers gathering in meetings (that don’t include Clarice) and Clarice has an attitude about that. All the killing, inability to catch Buffalo Bill goes here too.
The author paints Clarice’s external problem to appear as though it’s a challenge for her to be in a male dominated working environment. But then there are scenes where Crawford (her boss) notices she’s giving him an attitude (usually the cold shoulder) and he tries to explain where he’s coming from—that maybe there’s a different reason he does the things he does. So, her Mind domain is the real subtext that the author is highlighting.
The author uses the external as a misdirection device for this Mind MC.
Since the book is written mainly in 3rd person deep POV from Clarice’s POV, Clarice’s mind domain colours her interpretation of most events the book. She has a chip on her shoulder and is insecure because she’s a rookie without field experience, but she automatically interprets her discomfort as though it was because she is a woman.
I’m only half way through, but that’s what I’m so far seeing.
