Gould discusses other disenfranchised groups (like racial minorities) along with women because he says that the drive to denigrate women was part of a larger attempt to make the case that the other groups were inferior as well. He cites one of "Broca's disciples" who wrote about how the brains of black men showed that they were hardly more intelligent than women. Gould says that the attempt to prove women inferior is just part of an overall desire to prove that there are biological distinctions (along sex lines, racial lines, and perhaps others) that make some kinds of people more intelligent than others. He believes that this is a pernicious idea and wants to combat it. For this reason, he discusses other groups along with women in this essay.
