The brain is a blank canvas when it is created.

What the research says...

Modern neuroscientists have identified no decisive, category-defining differences between the brains of men and women.1

The idea that differences between boys and girls are biological and cannot be changed has been discredited.2

Instead, it should be acknowledged that the relationship between the brain and its world is a constant two-way flow of traffic and we need to pay as much attention to what is going on outside our heads as well as inside.3

But our children are immersed in a heavily gendered world.

This limits our early experiences. Some examples include:
  • A review of dozens of gender-disguise studies shows adults rating babies’ expressions and physical appearances differently based on the sex they believed the babies to be. Adults also tend to choose different toys for each sex, footballs and hammers for babies believed to be boys, dolls and hairbrushes for those they believe to be girls. They also engage with them differently – in a more physical way with boys and more verbal ways with girls.1
  • Analysis of the most popular children’s books in 2018 showed that male characters dominated and that a child is seven times more likely to read a story that has a male villain in it than a female baddie.2
  • Almost three times as many STEM toys were found to be advertised as for boys than girls.3
  • In toy catalogues, girls were 12 times more likely to be shown playing with baby dolls, while boys were 4 times as likely to be shown playing with cars. Of the children shown with guns and war toys, 97% were boys.4

From the clothes that they wear to the toys that they play with, this can limit children for the rest of their lives.

  • Toys provide training opportunities. But because play with ‘masculine toys’ allow children to develop skills that ‘feminine toys’ do not, and vice versa, stereotypes may restrict development.1
  • Certain clothes can limit physical movement. A study of 10-year-old children found girls did significantly less exercise when wearing a school dress than they did when wearing shorts.2

As they grow, brains pick up on social rules and learn what is “expected” of their gender.

Children are affected by this throughout their childhood from very early on.
  • Typically before the age of two, children are conscious of the social relevance of gender.1
  • By the age of 6, girls are less likely to believe that members of their gender are ‘really, really smart’. Girls also begin to shy away from novel activities said to be for children who are ‘really, really smart’.2
  • At age 7, children’s career aspirations appear to be shaped and restricted by gender-specific ideas about certain jobs.3

The effects can be harmful on their wellbeing and limit future opportunities.

Examples of these negative effects include:
  • Children in friendship groups that emphasised traditional gender stereotypes - girls having nice clothes and boys being tough - had a lower overall wellbeing.1
  • In classrooms where students believe that reading is a girls’ activity; boys showed less motivation, belief in their competence and poorer performance in reading-related tasks, while girls benefitted from this gender stereotype.2
  • Girls are less likely than boys to aspire to science careers, even though a higher percentage of girls than boys rate science as their favourite subject. Girls who aspire to science and STEM careers tend to describe themselves as ‘not girly’.3
  • Men who hold strong gender-stereotyped beliefs are at a higher risk of becoming violent towards partners.4
  • Beliefs held about how boys and men should typically act are more restrictive than those for girls and women. It is thought women should be communal and avoid being dominant; while men should be agentic, independent, masculine in appearance and interested in science and technology, but avoid being weak, emotional, shy and feminine in appearance.5

But there's good news! The brain is malleable, and this effect can be reversed.

Various studies have successfully demonstrated ways to counteract the negative effects of gender stereotypes. These include:
  • Showing magazines to children with pictures of boys or girls playing with toys that are not typically related to their gender.1
  • Allowing girls to read biographical stories of women in gender-atypical careers.2
  • "Empowering" girls by enabling them to imagine themselves doing activities in positions of power.3
  • By manipulating motivation, for example when women and men expect to get paid, they perform better at inferring what another person is thinking or feeling than those who do not expect payment. Gender differences disappear to reveal motivational differences instead.4

"We now know that, even in adulthood, our brains are continually being changed, not just by the education we receive, but also by the jobs that we do, the hobbies we have, the sports we play. The brain of a working London taxi driver will be different from that of a trainee and from that of a retired taxi driver." -Gina Rippon, The Gendered Brain
