Beryl Benderly at Science, Careers, writes about "The Complexity of Gender Differences in Choosing STEM"
My paper with Thomas Buser and Hessel Oosterbeek “Gender, Competitiveness and Career Choices,” receives a very nice summary (see also my former blogposts on it here and here)
I whole heartedly agree with the first and last sentence of Beryl:
"The question of why academically able girls are less likely than boys—even less accomplished boys—to enroll in science, technology, engineering, and mathematics (STEM) programs, especially in physical sciences, technology, and some engineering disciplines, has long bedeviled researchers and educators."
"Clearly, this is a complex problem that cannot be explained by any single factor or rubric."
