Left-handed men earn an average of 5% more than right-handed men, two British and Irish studies have discovered. The studies found that southpaw males tended to do worse in school—possibly because of trouble adapting to a right-handed world—but were more successful as adults. Female lefties, however, did worse in school and later earned an average of 4% less, the Daily Mail reports.
A doctor who worked on one of the studies said while it wasn't completely clear why left-handed men tended to do better in the labor market, it may be because the structure that connects the left and right brain is larger in left-handed men, leading to improved communication skills. Left-handed men also seemed to be more creative than righties, he added, a difference not found in women.
