I think that if you are abnormally attractive, you tend to grow up with abnormal social skills. If you somehow manage to be very attractive, very intelligent, and you have social skills, well, you're god's gift to humanity. I think that people have a baseline attractiveness (Attractiveness in itself is subjective) and that attractiveness can be amplified. I used to think I was quite ugly and my confidence suffered from that, and that was notable in the way I carried myself, which is a triple whammy (Typical high school throw in with some extra issues). With people telling me that I was attractive, I gained confidence, I started improving upon myself and my social skills, and as such, I am wholly a more attractive person than I was. Perhaps I misinterpreted what you meant by attractiveness going exponentially.
My friend Dragon made a topic about this, if you're interested.
