Can the root of this be ever determined ?
When you look at the unknown factor in the human brain ,
' Learned behavior ' appears to be just the tip of an Iceberg .
While I agree that personality types vary (as it's part of the reason we react and understand various situations in different ways), I'm a little hard pressed to believe that there is some dark nature which is more responsible for our actions than experience and understanding. Can the roots of feelings ever be determined? I believe so, and I say that from experience. It's not easy, and it can be rather complex as some conclusions are drawn in layers. I haven't seen anything in my personal observations thus far that would suggest that there is some other mysterious cause behind the feelings and choices of people.
No, I'm not a psychologist . So, of course, whatever I say will naturally be taken with a grain of salt. However, it seems to me that most of these things are connected to past events and how they were interpreted. There's the self and one's perception of the self. Most of what I see coming out of people has something to do with the defense of self-perception when the emotions are involved. Emotions, to me, are very intense and super fast thoughts. This is why when we acknowledge our feelings and the causes of them, those feelings may be subdued. It turns these emotions into thoughts that we can actually reason with. The choice to do so, or to refuse to do so, still has much to do with this perception of self and personal security.
