1. Boys are generally active, giving people the illusion of being smarter.
Boys are more active, girls are quieter, this is the embodiment of the character of different genders, and has nothing to do with IQ, but being active equals being smart, and being quiet equals not being smart, but it has become a stereotype for some people.
Regardless of whether they study well or not, most boys are more active at this age and give the illusion of being very intelligent.
2. Boys in junior high school are more likely to rebel, giving people the illusion that they are not stupid because of their personality affecting their grades.
Boys with poor thinking are more likely to lack self-management skills than girls, are more likely to be addicted to the Internet and games, and have more boys who have also become short-tempered, giving people the impression that adolescent rebellion affects their grades, but they are not stupid. But in fact, the lack of self-restraint is a sign of stupidity.
3. The inherent cognition of boys with great stamina restricts the willingness of some boys to fly first and be diligent to make up for their clumsiness.
There are almost no girls who will be evaluated as very smart, but they don't work hard, this kind of explicit praise is often the patent of boys, but this kind of high hat also makes many children who are not smart, but have strong self-esteem, are unwilling to work hard and bear the consequences of hard work and poor learning.
4. The abandonment of English to specialize in mathematics is more common in boys.
It is also related to some cognitions that good learning in mathematics is equal to smartness and English is equal to rote memorization, but learning mathematics well in junior high school does not prove that it is smarter than learning well in English, but the time invested is different, which will lead to different learning effects, girls have no smart baggage, and the learning time investment is more balanced, but boys tend to invest more time in mathematics.
