Human decision-making under unrestricted conditions

Current decision-making theories model the process of human decision-making under unrestricted conditions.  In my studies, I have examined the influence that the level of complexity plays on decision making.
Contrary to the prevailing assumption, I show that humans make better decisions under complex situations as opposed to simple situations.
In addition, my studies show a correlation between certain personality traits and decision choices, with open-minded subjects tending to select new approaches more often than conservative individuals.
