Actually, I think I’ve heard of this before. Although maybe not so directly.
It might be as simple as the differences between men and women.
There are physical differences, like in brain structure. Such as the connections between the left and right hemisphere, in men these were weakened early on in the womb by male hormones, and in women these connections between the two are much better. I was told by my psychology teacher that this is why women can jump from one topic to another and just keep building on it, and soon they are off topic talking about something completely different, but in their mind it is all related, because the signals in their brain can bounce around more freely, allowing for less focus, or I should say, they are multitaskers juggling around many thoughts at once, like a sea of madness.
But in men the weaker connections allows for compartmentalization, where it can more easily separate things into groups and devote most attention to one thing, without others popping in so much. (Although there is ADHD) But Compartmentalize things such as Work, School, Home, to be really general. But it could also I would imagine manifest itself as One language, two language, three language, and allow for less overlapping and confusion between them.
So it might just be that it is an easier task for a man to do than a woman.
Although baby girls tend to learn language more quickly than boys, and girls have much boarder vocabularies than men statistically, so it’s not all hindering in the language field. But for Multiple languages maybe there’s a bit of an obstacle to cross, that isn’t as high of an obstacle for men.
But also, women might not see it as necessary to advertise it, and show off.
I developed this one from having seen youtubers in general, what the girls do versus the guys.
Seems guys like to show off what they can do and some talent and that’s what their channel is about, whereas girls tend to stick to more everyday things, weather it be their life, or things they notice in life. There are exceptions, it’s not the laws of physics.
A lot of things that work together?
