I have watched this thread for a couple days and finally decided to respond. @arhag though left/right brain is not the case for this instance above ^, it does not mean left/right brain theory is pseudoscience. In fact, the right brain and left brains each help focus on coordination for the opposite side of one's body---left to right and vice versa.
I will however say that this is not exactly such a case...
In fact, the premise of this is incorrect. The "Dominance" of one side or another is not measured by whether you see it clockwise, counterclockwise or both.
