Reply To: Girls are more mature than boys

-Women obtain “da’as” at 12, men at 13.

The fact that women mature faster than men is Halacha L’Moshe Mi’Sinai.-

You speak about maturity as if it’s a one time event rather than a continuum. Girls mature sooner because the level they achieve is lower. It takes longer to bake a roast than toast.

See Maharal, Gur Aryeh, Parshas Tazriah. He says males mature later because they have a higher sheilamus.
