Poll at Feminist Philosophers on women's participation in conferences

There is an important poll going on promoted by the Feminist Philosophers, on whether women do indeed decline invitations to be keynote speakers more often than men, and if they do, what might be the reasons. We've been discussing this lately, as many conference organizers and volume editors have been reporting that they did invite women but that many (sometimes all) of them declined. If that's the case indeed, it would be important to try to figure out what mechanisms seem to be involved. So, if you are a female philosopher, go over there to report on your experience!
