There are different people and different personalities in the world. You make a personality concoction in your brain and you will find they are real. Everywhere everyone can be found. In the world there is nothing that is not there. Every kind is everywhere. I mean every personality is everywhere. This world is a perfect chaos. If you extend this a little more, we can say the chaos does not do any bias to any class, color, creed or religion. It has no bias to any region, or culture or geography.
There is a common practice to attribute certain traits to certain disciplines, regions, cultures or whatever way you divide humans into. In reality the personality does not dictate the discipline they chose. There are thousands of professions and none of them demand certain personality trait even though we think they do.
We like to think a politician needs to be a cheat or at least a cunning person, but it is not true. There are every kind of personality in politics and in fact the % of good, bad and ugly remain the same in all professions. There are as many percentage of "bad" politicians as there are percentage of "bad" doctors. Now obviously what does bad mean does not need to be explained as it does not matter. You can put any attribute and the rule still remains the same. There are as many percentage of philosophical thieves as percentage of philosophical religious gurus. You can keep going. There are certain professions we attribute honesty, honor or integrity to - Police, Doctors, Teachers. We like to believe they should have a higher level of attributes, but that is because of the profession being held in higher esteem. The people that enter these professions are just people. Similarly we like to believe underworld dons and people working in underworld business are just bad people but the fact is they are just people working in that profession, they will have similar percentage of good, bad and ugly.
Let's say that you could change anyone's profession, then if you put a thug in place of engineer and an engineer in place of thug the basic personality will turn out to be the same. If creativity is the hallmark of the engineer he will become a creative thug, because that's what he is. Similarly if the thug was a hardworking guy, he will be a hardworking engineer.
So there is no connection between profession and personality. This does on surface look counter intuitive, but if you think about it, it is very logical. If professions defined personality the segregation of human race would be so easy. If you believe in this theory the element of surprise disappears and you are more prepared to accept the world with more equanimity and understanding.
When a religious guru turns out to be a sex offender it becomes news because we attributed wrong traits to the religious guru profession. the percentages are the same, but the thug becoming sex offender is not a story because somehow you believe he is. The religious gurus are comedians, philosophers, sex offenders, highly learned about there profession, cheats, good at their jobs, boring at their jobs, interesting at their jobs in the same percentages as in any other profession.
Depending on your own bias you will only notice the stories you want to notice, if you are an atheist you will corroborate your religion hating theory by giving more prominence to support your theory. If you don't like doctors, you will like the story that tells that doctors did something wrong. If you have your brother in police you will find how angel the police are. But again the fact is - due to the nature of the profession the people in that profession have to do certain things as their daily routine but the personalities in those professions are as varied as the world is and they are microcosm of the world in every facet of human life. When you see a cheap and miser millionaire or a spendthrift beggar, it is not an anomaly, it is part of the percentages as all kinds are found in all professions / way of life. Professions don't define the personality, they are independent entity in the world more or less turning out to be in equal numbers everywhere.
In fact this does not just extend to personality traits in fact it extends to emotions. Percentage of happy and sad, spiritual and religious and scientific, passionate and dispassionate, also remains the same across the various boundaries.
The perfect chaos is because - you can go in and go out of the world, it remains the same - a perfect chaos.
