Is peer review biased against women?

In astrophysics, time-allocation committees allocate the time available on major telescopes and satellites. Facilities such as the Hubble Space Telescope are often over-subscribed by factors of 4 to 10, and writing proposals that win time in peer review is crucial to people’s careers.

I’ve recently had my first experience of serving on a “dual-anonymous” time-allocation committee, in which all the proposals are reviewed without knowing the proposers’ names.
