Interesting there are so many INTJs. Especially considering how rare this type is in the general population. The NT prevalence doesnt surprise me so much, as this board seems geared toward "do it yourself" retail traders, and market analysis would attract NT types in the first place. I'm a little skeptical of the results, but interesting none the less.
What is really surprising is how many people we have strong with the Introverted dimension. For Americans, that is quite rare, and I wouldn't think traders would be any more subject to being Introverts than extraverted, but then again, as I said earlier about the "do it yourself" type demographic of ET, perhaps Introverted traders are more likely to succeed as home based traders due to the lesser need for socialization...
But just reading some of your posts language usage and writing style makes me think twice about if your types truly are INTJ.
