A recent research study by a German agency carried out in 205 countries indicates that forty percent of the world’s population is left brain dominant, twenty seven percent are right brain dominant and 32 percent use both hemispheres in equal measure. The research also indicated that 57 percent of the male participants in the study are left brain dominant while fifty percent of female participants tap on to both hemispheres when making decisions (Sommer n.p).Right brain dominant persons are often times left handed
