Left and Right Handedness Is Complex, Like Politics A seemingly simple dichotomy, left- versus right-hand preference is remarkably complex and can be applied to the political environment.

Yes! An analysis of 19 different studies on left-handedness in twins (McManus, 1980) had shown that 15.09% of identical twins and 12.08% of non-identical twins were left-handers.

Why is left-handedness so rare? It comes down to these 2 words The rate of left-handed people has remained steady (about 10% of the population) for millennia. This theory could explain why.
