> I think there is a real issue around diversity in technology (and most other places in life). I tend to think of it as the PLU problem. Folk (including MVPs) tend to connect best with folks most like them ("People Like Us"). In this case, male MVPs pick other men to become MVPs. It's just human nature.
This theory makes intuitive sense, but some evidence contradicts it. Several studies have found that men and women discriminate against women equally, or even that women are harder on other women than men are:
* Steinpreis, Anders, and Ritzke (1999) http://www.cos.gatech.edu/facultyres/Diversity_Studies/Stein... ; Moss-Racusin et al. (2012) http://www.pnas.org/content/109/41/16474.full ; and Reuben, Sapienza, and Zingales (2014) http://www.pnas.org/content/111/12/4403.abstract found that men and women were equally biased against hypothetical academic job candidates in a study based on reviewing resumes with male or female names.
* Nosek, Banaji, and Greenwald (2002) http://projectimplicit.net/nosek/papers/harvesting.GroupDyna... found that in implicit association tests, women show slightly stronger implicit biases towards traditional gender roles in the "Gender-science" and "Gender-career" tests.
* Of course, there's Terrell et al. (2016) https://peerj.com/preprints/1733/ (the GitHub gender bias study that was discussed on Hacker News the other day) in which the authors found that women are harder on other women than they are on men but decided not to mention this in the paper https://peerj.com/questions/2002-do-you-have-data-on-the-gen... .
On the other hand, I also found some studies that concluded that men have stronger gender biases than women:
* Bowles, Babcock, and Lai (2005) http://papers.ssrn.com/sol3/papers.cfm?abstract_id=779506 found that male managers penalize women who attempt to negotiate salary more than female managers do.
* Uhlmann and Cohen (2005) http://www.socialjudgments.com/docs/Uhlmann%20and%20Cohen%20... found that men exhibited a stronger gender bias than women did in rating hypothetical applicants for a job as a police chief.
This is just what I dug up in an hour of searching; I'd be interested in finding more research on this. Does anyone know of a review paper on this subject?
