Code reviews may have grown in importance due to scaled back formal design documents and formal qa staff and processes.
> young women generally respond to it in a way that I like (e.g. they make a value judgement about what advice was worth taking and what wasn't and do it).
In my only 10+ years experience, I noticed women seem more defensive about their code being reviewed and I have to write long formal arguments if I'm suggesting any more than a trivial change. Then there will be a discussion afterwards and based on that it's 50/50 whether it gets done. Now I pad reviews with positives about the work to soften it in some probably transparent attempt to placate the reviewee.
With men, I review the code, make a suggestion, I usually get a note "sounds good, will do." That's not all men of course, there's always at least one guy who doesn't want his code reviewed at all, too good, doesn't see the point, etc.
