This is a very large study: "The new study (while confirming the 2013 work) is much larger and crosses many disciplines. This one is based on an analysis of 1.6 million papers written from 1950 to the present in the scholarly database JSTOR. While some first names are not gender exclusive, the study looked at first names that correspond with either men or women, but not both, at least 95 percent of the time, according to various public records. Papers written by people with names such as "Jody," which did not get to 95 percent association with a gender, were excluded from the database." Because of the size of the study, the results are likely to hold up upon further analysis.
