Quirrell, Dumbledore, Snape, Harry, and (increasingly) Draco have something in common. They are all creepy. These characters are intentionally inauthentic - acting as though they posses the specific beliefs, preferences, and abilities that they want others to attribute to them.

I feel unusually strong revulsion about this kind of deception - more than toward someone hiding their faults to manage their appearance, much more than toward someone being tactful and withholding or biasing sensitive claims to avoid conflict.

When I try to unpack "creepy", my mind suggests it has components of outrage at violations of close interpersonal social norms, distrust of unfamiliar thought patterns, fear of people with motivations that need to be hidden, and a special kind of disgust related to fears of idols, photographs, glassy eyed dolls, humanoid robots, and other simulacra. - the disgust toward an exemplar that doesn't fall clearly in or out of the human-mind category, toward a soul that has been captured in the depiction of a face and deprived of its intelligence and agency.

Are very intelligent people generally creepy like that? If I were a standard deviation smarter, would my peer group consist of people strategically concealing their identities and mutually modelling their mutual modelling up to the nth order of meta? Or is that inauthenticity just an abnormal personality type that doesn't correlate much with intelligence, but does fit nicely into a rationalist literary drama?
