Hmm...I work in a primary school, and it's pretty clear that the boys are more emotionally dysregulated than the girls (generally speaking - there are some dysregulated girls and some very well-regulated boys). There's also more disrespect for female teachers from boys. I only ever hear verbal threats from boys.
Why ? I'm not sure. I think the disrespect is a family thing, same with the verbal threats. These boys have been exposed to this somewhere.
The dysregulation is probably somewhat related to maturation, and presentation of things like ADHD and ASD - typical girl presentation is a lot quieter and easier to miss than typical boy presentation. Girls also seem socialised to gain teacher approval, boys less socialised to value teacher approval.
Both girls and boys are active and energetic, and neither sex finds it easy to sit for long periods of time. Girls wriggle, boys poke. (Do some girls poke ? Yes. Do some boys wriggle ? Sure. In general, there is less pro-social behaviour from the boys.
Because I am always looking for unconcious bias in myself, I spend a lot of time observing the boys, waiting for positive behaviour to notice and praise, so that they don't miss out. Side effect ? We tend to take the girls' efforts for granted, and so the girls miss out on the attention and praise.
I have a boy myself. I don't think boys are intrinsically incapable, or disruptive. Nor are they naturally more naughty or poorly behaved.
I think they learn those behaviours though, and have those behaviours reinforced at home. Which is quite depressing really, the number of young boys acting out masculinity in ways that don't contribute to learning. They were taught that sh*t, and they didn't learn it from their primary school teachers.
