Ever since the 1960s, feminists have stressed the importance of gender-neutral speech. More recent research has proved that using non gender-specific language actually impacts how people think.
Janet Hyde, a professor of psychology and women’s studies at University of Wisconsin – Madison, conducted a study in 1984 where she asked children to finish stories for which she gave them a first line, like “When a kid goes to school, ___ often feels excited on the first day.” When Dr. Hyde used the word he in the blank, almost all of the kids’ stories were about boys. When she used he or she, about a third of the stories were about girls. This effect is not only present in children, but has also been seen in similar studies with adolescents and adults.
