Children in the US are equating the jobs of scientists with women more than ever before, a study has found. Researchers at Northwestern University have concluded that children's stereotypical views linking men to scientists might have shrunk over the past five decades. They analyzed 50 years worth of children's artwork depicting scientists for the study, which encompassed the views of upwards of 20,000 children in the US. The new study marks the first time'Draw-A-Scientist' literature has been systematically reviewed. 'Draw-A-Scientist' literature is based on what children produce when they are asked to create an illustration of their idea of a scientist.
