Yeah that is the point. I would be interested to see which characteristics are hard set and continue to be expressed and which other ones are subjective to environmental influence

Well see it's so dependent on a ridiculous amount of factors. I had a bad experience as a child and I have a deep fear of helplessness so I have conducted my life since with prior thinking before anything that I do. Had that experience not happened things might be different. Because I conduct my life that way I'm in my very specific point of existence, any changes to what happened in the past can create unpredictable changes to the future, so if there is a person who has lived a completely different life they could be infinitely different unless they were sheltered their entire life.
