A deeper dive into the data

The other day I was annoyed that the Chronicle of Higher Education doesn't understand basic statistics.  In the face of the Chronicle's "study", Jokerst called for "a deeper dive into the data, and Merlise is the right person to lead that."  This statement shows a similar lack of understanding that the original Duke study already delved as deeply as the available data would allow. 

A proper deeper dive into the issue of salary equity would require more historical data, with an eye toward determining whether salaries in departments that became "feminized"** kept pace with salaries in departments that remained mostly male; however, it's not clear there's anything to find.  See, for example, salary concerns in psychology.

** that is, saw larger proportions of women join as faculty, relative to other departments.
