If you are into someone because the person is so intelligent, you are a sapiophile.
There are evolutionary reasons for this: those with intelligent partners are likely to have intelligent children, and they are likely to do better than stupid children.
This brings Robin to the novel Hannibal by Thomas Harris, in which the sapiophilic heroine Clarice Starling falls for the cannibal Dr Hannibal Lektuer and offers to cohabit with him.
“It would certainly make for interesting children, because psychopathy is presumably innate.”
So, psychopaths: work on your IQ, then you’ll also get women like Clarice Starling!
