Gli insegnanti danno voti migliori in matematica ai maschi, dice uno studio pubblicato da Victor Lavy dell’Università di Warwick e da Edith Sand della Tel Aviv University, dovuto più che altro ad un pregiudizio inconscio da parte del corpo docente. Il cosiddetto “effetto Pigmalione” ( «Just by believing that a student has an aptitude for something, the teacher makes it more likely to be true»).

In math, the girls outscored the boys in the exam graded anonymously, but the boys outscored the girls when graded by teachers who knew their names. The effect was not the same for tests on other subjects, like English and Hebrew. The researchers concluded that in math and science, the teachers overestimated the boys’ abilities and underestimated the girls’, and that this had long-term effects on students’ attitudes toward the subjects.
