The left-handed population is in the minority (at only about 12 percent), but there’s no shortage of them making history. Leonardo Da Vinci, Albert Einstein and four of the last seven presidents of the United States, including Barack Obama represent the left-handed contingent.
But according to a new study, being left-handed can impair economic parity. The median income of left-handed people was 10 percent less than that of right-handed people.
This information comes from the fall 2014 edition of The Journal of Economic Perspectives in an article titled “The Wages of Sinistrality: Handedness, Brain Structure and Human Capital Accumulation.” The study was the first to document this income gap.
