Hmm, I doubt that humanity is so sharply divided into categories of subordinate and leader based on your's and your colleague?s speculation. Do you think it likely that how people spend their free time necessarily reflects their position, status or calling in life? I'm pretty sure that there is many a technocrat that enjoys shouting at the telly during evenings and weekends.

The consciousness part of your speculation certainly seems to be a major component of leadership, but then again when held up against the "complex thoughts" section of your proposal it doesn't really stand up. Some leaders merely have an over-inflated view of themselves and their ability that in the end produces nothing more than an overwhelming sense of optimism toward a situation where none really exists. This can often come across as charisma, an appealing quality likely to gain popular support, but ultimately may not be very useful when intelligence is required.

Then again, self-awareness is probably a significant factor in regard to leadership (leading and directing yourself probably precedes leading and directing others), and probably explains why there have been so many narcissistic leaders in human history.
