Men are more likely to make sarcastic jokes than women. This phenomenon is due to aggressive hormones, such as testosterone, which can be induced in men. Sam Schuster, a professor at the University of Norwich Hospital in the UK, carried out an experiment by riding a unicycle on Newcastle Street and observing the reactions of men and women along the way.
Schuster recorded the responses of 400 people in total, and more than half of them expressed their views in words, most of them male.
He found that women are more likely to give encouraging comments, while men often sneer in the form of jokes. 75% of men will joke loudly, for example: "Why, lost another wheel?" But the proportion of women who joke so is very low.
Schuster said that male jokes are generally ironic. Young men react more aggressively. They usually pull down the window and shout loudly. As men grow older, their verbal aggressiveness will decrease.
