Seven years ago, a group of female scientists at the Massachusetts Institute of Technology produced a piece of research showing that senior women professors in the institute’s school of science had lower salaries and received fewer resources for research than their male counterparts did. Discrimination against female scientists has cropped up elsewhere. One study conducted in Sweden, of all places--showed that female medical-research scientists had to be twice as good as men to win research grants. These pieces of work, though, were relatively small-scale. Now, a much larger study has found that discrimination plays a role in the pay gap between male and female scientists at British universities.
Sara Connolly, a researcher at the University of East Anglia’s school of economics, has been analyzing the results of a survey of over 7 000 scientists and she has just presented her findings at this year’s meeting of the British Association for the Advancement
