For Girls in STEM, Belonging, Not Brain Structure, Makes the Difference : Little real evidence is available to indicate that the brains of men and women are "hardwired" differently, yet, perhaps due to lingering stereotypes, women remain underrepresented in the science, technology, engineering and math (STEM) fields.
In her book, Pink Brain, Blue Brain, Lise Eliot writes, "What I found, after an exhaustive search, was surprisingly little solid evidence of sex differences in children's brains."
This appears to run contrary to common claims that women somehow are less adept at STEM, a conclusion that would seem to follow from their marked underrepresentation in university science and technology programs. (See the statistics below for more information.)
Eliot, who is a neuroscience professor, notes, "Only two facts have been reliably proven." The first is that boys' brains are larger than girls' -- "somewhere between 8 and 11 percent larger, depending on the study," which is a difference similar to gender differences in height and weight.
