Are there more right-handed people than left-handed people?

There's really no accurate way to tell, since, in the 1970's and 80's, many parents forced their left-handed children to use their right hand.  Because of that, the current generation would seem to be mostly right-handed, despite the fact that their brains are primarily left-dominate.  In a study done by the American Psychological Association, five groups of people were given 13 activities to do with one of their hands.  Some people used their right hand for one activity and their left for a another; others only used their right hand; the rest were either left-handed or ambilateral (could use both hands).  From this study, it seems that there are more right-handed individuals than left or ambilateral.  The percentage of left-handers is comparatively small next to the percentage of right-handers.  Based on this study, we would conclude that there are more right-handed people in the world than left-handed people.  However, one must take into account that some of these right-handers may have been forced away from their left-dominate brains during childhood.  There are too many problems with this experiment that we cannot control, so therefore, no accurate conclusion can be made.
