I don't think marriage is dumb, but getting married so young 100% is.
I disagree. It used to always be the way it was done.
Getting married young is kinda dumb, since neither partner is going to truly be mature enough to handle that kind of relationship.
Secondly, it used to be done that way because of sexist practices in medieval times.
It actually depends on the society more than biology to a certain extent. (Especially as people did handle that kind of relationship.)
Really? Give your evidence due to the statement.
True, but by personal IRL observations, many of the people in that age range, (AKA my age range) are not mature enough for ANYstable relationship.
Forgive me for being so blunt, but your scope of observational research is exceptionally narrow; bound by time, place, age range and (most especially) culture.
And if you wanna go do the research, it used to be a thing that once a young woman had her period, and started developing, she was considered ready for marriage, and was married off, usually to some older guy. The marriages were also generally used to consolidate alliances and business deals. They were also done without any consideration to the bride's preference/likings/wishes. In short, women were treated like property.
(This is all info from a few unit studies I did in grade 7-8, so if any of this is proven innaccurate by actual research.. then obviously I'm wrong.)
I don’t have research to dispute this, nor will I attempt to being sure it did happen. But I will raise the fact that it I should not a stain on the institution itself, just like divorce.
