1. The age at which children start school has gradually lowered. This has reached a point where ~80% of boys and ~20% of girls do not have the brain maturity to pay attention (boy brains mature at a different schedule from girl brains). The result is that teachers will group classes with young students into two groups: one that is mentally ready to play the educational games and the other group that can play freestyle. Kids no matter what age are very good at learning who the "dumb" group is, even though teachers never / almost never have a negative attitude towards the group that isn't ready to learn. This causes children to think, "The teacher hates me" which causes them to hate school.

2. Schools tend to have extreme punishments towards any kind of violence, even healthy violence. E.g., banning snowball fights. This also creates an environment that is bad for ~80% of the boys and ~20% of the girls, who want to have fun this way.

3. Even intellectual discussions of violence are frowned on. The author received awards when he was a child for writing a story about a man who was trying to escape East Germany and ended up getting both his legs blown off. Nowadays it's hard to imagine anything other than that child getting detention / the police called on them / counseling / etc. This frowning on discussions of violence again causes harm, but a disproportionate amount of harm is experienced by the boys.

Which, actually, is a big part of why this persists.

On the differences of gender dropout in Italy was a very interesting point. They suggest that it is simply easier for a boy to dropout from High School to get a job than it is for a girl.

So when we mention girls do better at school. Perhaps a factor such as incentive may play a role.

The paper suggests an uneducated boy will fare better on the job market than an uneducated girl and thus have less incentive to do well at school and drop out earlier.

I thought it was an interesting view that deviates from the usual ones

I saw one paper that showed gay boys excelled at school on average. But they were clear on that how the data was collected may have affected the outcome. In US for example, a boy that admits to being gay is more likely to come from a liberal well educated home. And children of well educated parents tend fare better at school. Knitting socio economics back to the reason for doing well.

Some people say high achiever should go into the economy, it is only right that they earn more. I think these thoughts don't really come from high achievers.

or because since 1980 all the teaching method used by teacher are designed for girl learning style and none are designed for boy learning style!

Because there are no incentive for boy to work hard and get good grade because they never receive praise for good work.

mostly just anecdata across the net driving that conclusion

IMO - This is one of the more obvious answers to this phenomenon
