Explanation of the six temperaments Greedy, hating, deluded, faithful, intelligent, speculative

I know they may seem self exploratory on the surface, but I'm looking for an understanding to more properly determine how one is to know which one he/she is someone else is.
One of the most important topics in Buddhism is the lack of basis for "identity view". This comes out, for example, in MN62:


  “Rāhula, you should truly see any kind of form at all—past, future, or present; internal or external; coarse or fine; inferior or superior; far or near: all form—with right understanding: ‘This is not mine, I am not this, this is not my self.’”


Having faith that identity view is baseless, one is led to conclude that those who cling to identity view are often:


Greedy, which can be recognized in the unfairness and suffering of those excluded from shared resources such as drinking water during a drought.
Hating, which can be recognized in a lack of compassion for others such as saying "steerage passengers will have no lifeboats."
Deluded, which can be recognized in a never-ending grasping at the vanities of health, youth, and life.


Yet those who have identity view can also be:


Faithful, which can be recognized in a willingness to experience the fruit of teachings of the Buddha personally
Intelligent, which can be recognized in a discernment between skillful qualities and unskillful qualities
Speculative, which can be recognized in a struggle to understand the meaning and worth of the teachings of the Buddha such as "This is not mine, I am not this, this is not my self,’"
