This is perhaps an oversimplification of things, though it does reflect the expected bell-curve distribution. Presenting PDB’s Five Levels of Attraction:
Level 5 = Movie stars, supermodels, the very elite that is beyond reach to all but a privileged few.
Level 4 = those who are almost as good-looking as the level 5s (and in some cases more so), but haven’t reached the same level of fame, social status, etc.
Level 3 = Most of the population. More-or-less attractive, but not to the take-your-breath-away point of level 4s and 5s often the overlooked “best friend” of a level 4.
Level 2 = Not exactly Quasimodo, but not particularly exciting to look at, either.
Level 1 = Quasimodo
Of course, there’s always that eye-of-the-beholder factor to consider, which tends to skew results. But I’ve got a hunch that no one is going to pay any attention to anyone below 2.
