When a bro rates a female on the 0-10 scale, the personality principle describes the influence of personality upon the rating. The effect personality has in terms of rating decreases toward the extremes of the scale.

0's and 10's: No possible change from personality
1's and 9's: Possible change of 1 point up or down (as a result of personality)
2's and 8's: Possible change of 1 point up or down (as a result of personality)
3's and 7's: Possible change of 1.5 point up or down (as a result of personality)
4's and 6's: Possible change of 1.5 point up or down (as a result of personality)
5's: Possible change of 2 point up or down (as a result of personality)

A 10 will always be a ten no matter how bitchy or cool they are; a 5 can possibly be a 3 or a 7 depending on their personality

PSA for all women, your personality matters!
Austin: "Hey dude, I met a dime last night but she was a mega bitch. Still a 10 though.
Andrew: "Did you meet any other women?"
Austin: "Yeah there was this decent-looking 5 but she was super cool. After the night was over, I'd rate her a 7."
Andrew: "That's The Personality Principle at work, bruh."
