Gender bias is not a phemomenon limited to tribal communities, New Zealand, or even the English speaking world. Gender bias can be found nearly everywhere, starting with the socialization of girls to focus on some traits and skills while boys focus on others. Classic examples include encouraging girls to be more interested in matters of appearance and social skills and less focused on math skills. Chapman (n.d.) claims "Teachers socialize girls towards a feminine ideal. Girls are praised for being neat, quiet, and calm, whereas boys are encouraged to think independently, be active and speak up."
