Sex-Typed Interests: Do Early Hormones Create “Empathizers” and “Systemizers”?

There is currently widespread scientific endorsement of the idea that early hormones channel our fundamental interests in masculine or feminine directions. Even before the research leaves the pages of scientific journals, this idea is directly linked to career choices and chances, education, the division of labor in families, and the “drive” to be a leader versus a nurturer. Psychologist Simon Baron-Cohen, for example, believes it explains the sex disparity among top scientists, suggesting that a “male-type” pattern of fundamental interest in inanimate objects makes one a “systemizer,” while fundamental interest in people (the “female-type” pattern) makes one an “empathizer.” For historically minded skeptics, it’s hard to reconcile women’s advancement over the past few decades with the idea that innate sex differences are the key force behind sex distribution in education, occupations, and the division of labor in families. But there are even stronger reasons to question this theory, based on a scientific evaluation of the studies themselves. In particular, how well do the sorts of interests that are studied in relation to prenatal hormone exposures actually connect to the kinds of differences they are meant to explain in occupations, education, and family life? Based on a systematic review of more than 300 studies linking early hormone exposures to sex-typed patterns of sexuality, cognition, and interests, Professor Jordan-Young will explore what is actually known about the influence of hormones on so-called “masculine” or “feminine” interests.
