If part of the plan for the growth team is to invite
anonymous editors to sign up, why not tailor some of those invitations
specifically to female anonymous editors? Then you could add a measure,
retention of female editors, to that particular growth project. The results
should be instructive.
At the risk of biting into something contentious... How would that
work? What would the message say: "Have you considered creating an
account? Its free. Doubly recommended if you're a women!" I have
trouble imagining a gender-specific account creation invitation that
doesn't sound creepy.
Additionally, actually measuring success rates by gender would require
knowing people's gender. Its conceivable that requiring people to
disclose their gender could have a negative impact on the gender gap.
(Or maybe it wouldn't. I have no idea)
