Once children hit school age, teachers—even female teachers—subconsciously believe boys are better at math than girls. In one study, when a group of teachers graded math tests with no names on them, the girls outscored the boys. But when another group of teachers graded the same tests with names, the results were reversed: they gave higher grades to the boys than the girls. All of the teachers, by the way, were female.
This is frustrating and scary. And I’ve already seen it happen!
