I, too, hate right hand turns. And I remember one young lady from Great Planes many years ago making the same comment. I have a hard time visualizing the roll attitude of the aircraft in a right turn or right roll. I think the idea that it has something to do with left brain dominance is probably correct. It would be interesting to do a study of artists who fly to see if they have the same issue with left turns. (Artists are supposed to be right brain dominant.)
