Employers and educators in perceived "masculine" or "feminine" fields can also help eliminate existing stereotypes, such as by promoting awareness that computer sciences ("masculine" and "nerdy") help solve health problems ("feminine" and "caring") (Wang and Degol 2016), or by reaching out and establishing direct contact with students and schools (OECD, 2008). Providing objective and reliable career information to both boys and girls, including personal contacts with employers and professionals, can help reduce the influence of informal sources of information, which may lack reliability, solid information and impartiality, and confine choices to the known and familiar (OECD, 2004). Other data show that few pupils have a full or accurate understanding of science-related professions; many are largely unaware of the range of career opportunities that are made available with training in science and technology.
