Hi!
I believe that WMF Discovery is the team that is best suited to address matters like this, so I am forwarding your email to the Discovery mailing list.
So on this: https://www.google.com/#q=gender google produces:
https://en.wikipedia.org/wiki/Gender Wikipedia There are only 2 genders. Male and Female. Retrieved from "https://en.wikipedia.org/w/index.php?title=Gender&oldid=722247975" ... Gender identity · Sex and gender distinction · Sex · Grammatical gender
Strange thing is that google is retrieving old revision. I have no idea how google produced that result, but given that it has a specific link, I wonder if it's a targeted action - i.e. somebody submitted this particular revision URL to Google.
I wonder if we can ask Google to somehow down-grade old revisions and not consider them top results?
