Yeah.. one thing we humans like to do is seek to prove our assumptions first instead of steel manning the opposite view. 

Been realizing how I have done this in the past lately

Gender wage gap: single men make the same as single women - St Louis Fed

Scoresby

One of the exercises I have students do in my upper div econ class is to run regressions of earnings on gender, to statistically estimate the gender wage gap.

I show them that if you *just* include gender, then the gender wage gaps looks like 30%.

However, as you start accounting for other factors, like hours worked, industry and occupation, education level, the wage gap falls significantly.  It's still there, but much lower than it initially seems.
