A new Yale study has revealed that there is a pervasive and unconscious bias on university campuses that favors male science students over their female counterparts. The result is fewer women in scientific professions. And as a recent Sunday Review article pointed out, it's not just in science where women are underrepresented, electrical engineering, a huge growth industry, is dominated by men. Should there be affirmative action, or something similar, to advance women in science and related subjects?
