Nine out of every ten humans are right-handed, an imbalance that researchers for decades have attempted to
explain, without definitive success.
One of the ideas considered is the fighting hypothesis, which suggests that left-handedness provides an
advantage in combat, albeit with an overall hit to physical health that keeps lefties rare in the population. Indeed,
males — who historically have competed most strongly for resources and mates — are left-handed at slightly
higher rates than females. Moreover, studies suggest that lefties tend to outperform right-handed people in fighting
sports as well as in sports that require hand-eye 1 like tennis, baseball, and volleyball. This is likely
because players are unaccustomed to competing against lefties as they are rarer.
However, a big problem with the fighting hypothesis is that its predicted health disadvantage hasn’t 2
in large studies. On the whole, left-handed people don’t seem to suffer from more health problems than
right-handed people, nor do they live shorter lives.
Left vs. Right
Noticing this 3 issue, a trio of scientists based out of Lund University in Sweden and Chester
University in the United Kingdom proposed an update to the fighting hypothesis that comports better with current
data. In an article published in the journal Symmetry, Matz Larsson, Astrid Schepman, and Paul Rodway 4
that right-handed humans actually had a greater fighting advantage over much of our species’ history, which is
why they’ve become far more numerous.
“When left-handers became rarer, they gained a surprise advantage and the 5 of left- and
right-handers in a population stabilized,
