No previous study, to my knowledge, has demonstrated that the well-known gender gap in school grades begins so early and is almost entirely attributable to differences in behavior. The researchers found that teachers rated boys as less proficient even when the boys did just as well as the girls on tests of reading, math and science. (The teachers did not know the test scores in advance.) If the teachers had not accounted for classroom behavior, the boys’ grades, like the girls’, would have matched their test scores.I suppose one could make an argument that there's a problem here. Teachers of primary and secondary schools are almost exclusively female, after all; perhaps there's some sexist preference for well-comported girls over unruly boys. However, my guess would be that male teachers mostly like well-behaved students also.
Rather, we have a kind of sorting going on whereby people who are good at sitting still and learning to speak (and think) in an approved way go into certain kinds of jobs, and people who are uncomfortable with that find other ways to make a living. In terms of the long-term happiness of everyone involved, that's a good thing.
It happens to be true that one class of such jobs pays better than the other class, but that's an artifact of the present moment. As the article itself points out, it didn't used to be true: and as technology continues to change, more and more options open up for people who just aren't very well adjusted to the 'sit-still, be-quiet, watch-what-you-say' environment that predominates in the schoolhouse and the New Model Office. It's a pretty oppressive and unpleasant environment, as unpleasant as any factory to those who chafe at it.
So yes: boys are more unruly. It's very important to try to teach them to obey the rules and show respect. But on the final analysis, their happiness as adults doesn't depend on learning to sit down and only say things considered polite. It depends more on them finding a way of life that comports with who they are. The economy won't stay like it is forever, and the office won't be the dominant mode of economic life forever.
Besides, if you're really unruly you can go into politics. We need a whole new political class anyway.
