The most interesting sentence I’ve read today (so far)

Our results suggest that an increase in the proportion of girls [in school] leads to a significant improvement in students’ cognitive outcomes.

Here is the paper, here are non-gated versions.  The estimated benefits are of similar magnitude for boys and girls.  It seems that girls make the classroom a more civil place.  The implication, I suppose, is that all-girl schools impose a negative externality on boys and I don’t just mean from the side of beauty or fun.
