There’s a serious problem with this assumption. In reality, one or two women will not civilize a team of brogrammers.
This isn’t the only problem, or even the most significant one. Your job description, and the reason she joined, is not to change other people’s ‘immature’ behavior. It’s to build. That’s a horrible responsibility to put on a team member, especially because it’s going to be implicit...and to be honest, probably resented by the ‘immature’ cretins on the team already. Ignore whether this ‘strategy’ might be effective and be fair to the hiree!
