In a landmark study involving over a million students, it appears that the reason boys dominate girls in STEM fields is not that they are better than girls at it (the reverse seems to be true) but, perversely, that gender differences are lower in non-STEM fields.
About the STEM grades, which are often abused as an explanation:
A classroom with more variable grades indicates a bigger gap between high and low performing students, and greater male variability could result in boys outnumbering girls at the top and bottom of the class.
“Greater male variability is an old idea that people have used to claim that there will always be more male geniuses – and fools – in society,” O’Dea says.
The team found that on average, girls’ grades were higher than boys’, and girls’ grades were less variable than boys’.
But girls' and boys' variability were much closer in non-STEM fields.

The real question is why people worship grades and test scores when the standards are so obviously low to begin with. The fact that the standards themselves are abysmal means that meeting or exceeding them is just not impressive. Our school system is a disaster, so excelling within it is no accomplishment.
