- Girls get better educational outcomes in single sex schools.
- Boys get better educational outcomes in mixed schools.
- Girls who go to single sex schools seem reasonably normal.
- Boys who go to single sex schools are thuggish ruffians of the first water.
My simple proposal is that all classrooms should be fitted with one-way mirrors down their length. Boys and girls would be separated by the glass such that the boys could see the girls but not vice versa.
