An average man is seen to be taller and heavier than an average woman and 30% physically stronger in the upper body (LifeForm Newtowrk Inc.). Internally, “men and women have different levels of certain hormones; for example, men have a higher concentration of androgens such as testosterone, while women have a higher concentration of estrogens (LifeForm Network Inc.). These things are rather obvious as we all perceive men to be the physically stronger sex than women. Later in our discussion, this premises on differences will lead to some conclusion about gender roles.
As to intelligence, there is known to be little difference between men and women. Specifically, the findings are: ”an average man performs better on tests of spatial and mathematical ability, while women perform better on tests of verbal ability and memory” and “men’s IQ has greater variance, which means that there are more men than women in the very high and very low IQ groups” (LifeForm Network Inc.). Behaviorally, men are known to be more physically aggressive, has more sexual drive, has more positive attitude than women, are less emotions but also has less willingness to express emotions to women (LifeForm Network Inc.).
Different societies have difference views of men and women. Some countries, like the Muslim countries and in Africa, women are treated much less than in other countries. One thing in common however is that women are viewed as inferior to men. Only the magnitude of difference matters. Men are usually more educated, has higher position and therefore higher salaries than women, although in some democratic countries the gap is closing in.
