I have a similar metric built after years in business, tech, VC, etc. Its quite simple, totally not politically correct, and very tongue in cheek. But for your entertainment:
Dimensions for analysis:
x-axis factors:
1) Height short -> tall
2) "WASPiness" waspy -> non-waspy
3) Sex "female" -> "male"
4) attractiveness troll -> model
x-axis, (0-N)=1+2+3+4
y-axis factor:
5) Odds of Incompetence likely useless -> potential illuminati
y-axis, (0-N)=5
So it turns out the further away from the origin (0) you get on the x axis, the closer to the origin (0) you get on the y axis. That is, the taller, waspier, more 'male', and more attractive you are the higher are the odds that you are incompetent in every sense of the word. So if you ever meet a short, non-waspy, non-male, unattractive person in a position of power, be very, very careful. They are probably extremely competent. ;-)
This model is clearly US centric, btw, I suspect it wouldn't hold up very well internationally ....
