Highly educated people earn more if they are left-handed. The pay gap, relative to right-handers, is especially strong for those with low earnings relative to their level of education (e.g., academics). If they are men they earn 15 percent more. Here is the paper.
This earnings result appears ungrounded but it does not surprise me. Left-handers have idiosyncrasies, obsessions, and downright insanities which lift some of them into productivity heaven. If they are not earning a lot they probably love what they do.
I like other left-handers (yes I am one) at a disproportionately high rate and they fit disproportionately into the right-hand-tail of the distribution of my liking. One of my absurd beliefs is that I can tell which people are
left-handers simply by observing their personalities and their charming bits of ever so slight yet always on the surface awkwardness.
Did you know that lefties also have higher rates of irritable bowel syndrome?
For some odd reason, I play all sports but basketball with my right hand.
