Masculine fields of study

Steve Sailer reports:

The Chronicle of Higher Education has a fun interactive graphic of the sexes of the authors of a couple of million academic papers going back to 1665. For the last 20 years, the most male dominated field studied is math, then operations research, then philosophy, and economics. In philosophy, the most masculine subfields include space and time and set theory, and the most feminine moral philosophy. 

In general, women researchers find living things more interesting, especially young living things.

Especially feminine subfields include sociology of gender, anthropology of dance ethnology, cognitive science of early childhood development, pollution and occupational health of cancer risk, and mycology of yeast.

The single most masculine subfield in the study is the mathematics of Riemannian manifolds.
