In a study on aggression, a group of college students are given an experimental task intended to be purposely frustrating. Than, the participants are given a task that forced them to administer (fake) electric shocks to another participant. Given what we know about gender differences and aggression, what should the research expect

It is common knowledge that, generally speaking, men are more aggressive than women. Evolutionary psychologists Daly and Wilson (1994) examined data of homicides by gender in 14 countries during different eras, and found that overall men committed homicide 26 times more than women. On a different 1988 study, they also found that men were victims of homicide on 90% of the cases. On his theory of social roles, psychologist Leonard Berkowitz offers an explanation for this: he argues that men and women have usually been educated to carry on different social roles: while women have been historically expected to be delicate and feminine, men are expected to be assertive and strong, which often goes hand in hand with displaying violent behaviors. Based on this, it can be expected that on this particular experiment, men will be more willing to administer electric shocks to other participants.
