Who is more intelligent or smarter — men or women?

The difference are very small. Some research suggests that men tend to have IQ’s which are 2 - 4 points higher than women in the same situations.

Also The IQ of men are more variable, there are more extremely intelligent men and also more extremely dumb men.

So modern educational systems are more biased towards females. This is also noticeable, because females graduate with more bachelors and masters and with higher grades. However in a study in Finland, when boys could exercise before learning they did significantly better in all areas than when they did not have such opportunity to exercise.

It is very important to note that there are significant differences in brain anatomy and chemistry. Therefore I think it important that educational systems should be adapted to both the learning styles of females and that of males. And then I mean that males tend to need more physical exercise because they tend to be more energetic and need to get rid of that excess energy before they can focus.

There is a lot of evidence to support the hypothesis that men are biologically better at math and spatial memory than women, due to the masculinization of the brain.

However research also suggests women tend to be better and language and memory recall. They tend to be somewhat more prone to do unbiased analyses of situations as well. These differences are mostly small but are noticeable.

But there is also evidence to the contrary. However this contradicting evidence could be due to biases of the researchers, the setup of the experiments, faulty statistics or other factors.

There are a lot of differences in the brain between the genders. Most if not all of these differences are biological and happen after 8 weeks of pregnancy.

It has been proven that men think on a very different scale than women do. This is obvious when the connectome of the brains are compared when men and women do several tasks. Even memory recall is done via different pathways between men and women.
