Go Get 'Em, Lefty!
We examine whether handedness is related to performance in the labor market and, in particular, earnings. We find a significant wage effect for left-handed men with high levels of education. This positive wage effect is strongest among those who have lower than average earnings relative to those of similar high education. This effect is not found among women.A strange result... why would this effect exist? And why would it exist only for men, and not for women? And for highly educated men, but not for less educated men? I wonder if this is not just a "random" result.
Unless someone has a reasonable theory, I'm likely to dismiss the result as a strange fact, likely due to randomness in the data (the relationship between education and handedness has a t-stat of only 2 in the first regression, Table 2, and more detailed looks at this result that follow also seem to have just-signigificant statistics). For what it's worth, the authors also fail to provide a reasonable theory:
We explore some possible explanations for these findings but are not able to provide concrete evidence leading to a theory that can reconcile all of the various facts we identify. We recommend this as an avenue for future research.
