- the tendency to exaggerate differences between the sexes, suggesting there are real and enduring differences between the 2 sexes
- tends to devalue one gender in favour of the other (often women) leading to one being judged by the others standards
- e.g. Freud's theory of psychosexual development:
. same-sex identification leads to the formation of the superego (morality principle)
. a girl's identification with her same-sex parent is weaker than a boys resulting in a weaker superego
. girls/women are morally inferior to boys/men
