And it, like most of the statistical papers surrounding the pay gap suffer from what I personally affectionately refer to as the "peanut butter spread" problem.
The implicit assumption of pay gap studies is that if you group all jobs into a category and then segment them by gender both groups should have equal distribution of some set of attributes X, Y, and Z. I can't help but feel as if looking at genders (or really any segment of society) and assuming they have "independent and identically distributed"[1] random variables is flawed.
For example, UC enrollment of undergraduate students for Engineering/CS has hovered around 14.5% for the last several years[2]. My fraternity, however, was more than half Engineering/CS majors at one point in time during my time as an undergrad at UC Davis.
One way to look at this is:
* My fraternity favored Engineering/CS majors
another way would be:
* My fraternity discriminated against non-Engineering/CS majors
But neither is actually true. The fact my fraternity had a higher percentage of Engineering/CS majors than the overall student body distribution does not imply any sort of causal influence insidious or otherwise; correlation is not causation.
Moreover, all things being equal, should my fraternity have the same distribution of majors as the overall student body?
I would argue no. Membership of a fraternity, or any other student organization for that matter, should be a personal choice. Whether it is a collection of like-minded individuals, similar majors, or similar interests that motivates you to join the choice should be yours to freely make. If that means that individual fraternities all have non-identical distributions of majors, then so be it!
Make no mistake, I am all about freedom of choice. I also am steadfastly libertarian and individual freedoms (and this applies equally when it comes to gender considerations). But I don't necessarily believe that in a Utopia-esque society where there is perfect freedom of choice that there would also be perfectly equal distributions of any sort.
