A comparison of gender stereotypes held by US citizens across the years, shows significant shifts in how men and women are perceived. The most striking difference emerges in perceptions of the intelligence of men and women. In 1946 about three quarters of the respondents believed that men and women are unequal in terms of their intelligence, by 2018 three quarters thought that men and women have equal intelligence. The authors indicate this shift in gender stereotypes follows from visible changes in the social roles men and women fulfill in society, and the greater participation of women in higher education and high-level functions at work.
