RTE today carried the shock news that girls outperform boys in the Leaving Certificate. To be fair the article notes that this is not new and is observed internationally. What I am not aware of is evidence (and no, anecdotes - even from taxi-drivers- do not count) on why this is so.
There is no shortage of theories of course: the feminization of teaching, the feeling of displacement and general uselessness by males due to the evils of feminism etc etc. But this seems an important enough trend to be worth studying and, even, doing something about.
