Little girls start believing gender
stereotypes by age 6. A 2017 study
found that the stereotype of brilliance
being more associated with men
influences children as young as 6, an
age where girls begin to ignore activities
that are said to be for smart people.
At age 5, the kids in the study saw both
genders as equals, but by age 6, the girls
thought of the boys as more intelligent
and avoided playing games intended for
‘really, really smart’ kids. Source Source 2
