A Contrarian point of view is it Nautre or Nurture?

I speak from experience on this subject, after all I am an unabashed Contrarian.

The question I wish to pose is as follows:

Is the fact that I am a contrarian something I learnt growing up, or is it something I was born with.

The first thing I need to identify is whether I am a contrarian in every aspect of my life, or does it refer only to trading. My answer on this is that I believe I really am only a contrarian when people speak of a sure thing. In other words when there is such conviction by a group of people I find that I have an automatic response to go for the other side.

It possibly stems from the fact that I absolutely hate it when people are so full of themselves or their analysis that they are not prepared to consider an alternative possibility.

Coming back to the isse of nature vs nuture.

I don't believe my upbringing was one to confront the establishment and to intellectualise all analysis. I don't believe my sister is a contrarian. Having possibly refuted both the nature and nuture argument.

I am leaning to the belief that my contrarian disposition is part of my psychological makeup which is part nature part nurture. To be a contrarian you need to have broad shoulders so you need to be prepared to take on the establishment. Surprisingly you don't need to enjoy conflict which I don't on one hand and do on another.

Can a contrarian be trained, and what gives me the right to call myself a contrarian?

The above questions need to be analyzed and for now I wanted to capture the essence of the question, ignoring whether I may or may not have made any sense.

I will conclude with a last observation. Being a contrarian requires a pretty sizeable ego. Being a good trading contrarian requires an insight and control of ones ego.
