60秒科学:物理系学生普遍表现出对男教授的偏爱

（单词翻译）

Male and female actors gave physics lectures to college students. All students thought the males were more knowledgeable¹. And whereas female students gave a a slight nod to women teachers, male students thought male teachers were vastly better.

Why aren’t there more women physicists³, and in senior positions? One factor may be unconscious biases⁵ that could keep women physicists from advancing—and may even prevent women from going into physics in the first place.

Amy Bug⁶, a physicist² at Swarthmore College, examined the bias⁴ question.* Her research team trained four actors—two men, two women—to give a 10-minute physics lecture. Real physics classes watched the lecturers. Then the 126 students were surveyed.

When it came to questions of physics ability—whether the lecturer had a good grasp of the material, and knew how to use the equipment—male lecturers got higher ratings by both male and female students.

But when asked how well the lecturer relates to the students, each gender⁷ preferred their own. And while female students gave a slight preference to female lecturers, male students overwhelmingly rated the male lecturers as being superior. The research appears in the journal Physics World.

Bug says the results may be evidence of inherent biases that could hold women back—along with economic inequalities, such as lower wages and smaller start-up grants. Which reduce career acceleration and thus the amount of force available to crack the glass ceiling
