You're absolutely right, and I have no idea why you're being downvoted.
My best guess is that something I type triggers someone's preconceptions about a topic and then they reflexively seek solace in the down triangle. Edit: Or, perhaps, they are rate-limited by HN and can only use the triangles?
I did not downvote your above comments, but I can see why others might. Your argument, while perhaps not intended to, parallels a standard trolling technique of asking for evidence and then dismissing any information presented. You complain about one study not being broad enough, about others for being behind a paywall, and still others for being on twitter. Ultimately, the standard you ask for ("this pattern has only been observed with women", and, "this pattern has only been seen with men") is unreasonably restrictive, as if a pattern that was only 99% reliable in separating men from women would not be sufficient. It makes it appear (again, this may not be true, it's just the appearance) that you're not making a good-faith effort to evaluate information fairly, but are instead holding firm to a preconception and requiring extraordinary proof before being willing to reconsider. Your snarky "triggers ... preconceptions" response does not help this perception (and, FWIW, I did downvote this comment, because your "guess" is of negative value -- it only serves to upset your supporters and anger your detractors.)
EDIT: also FWIW, I would love to see good data about potential differences in vocal patterns in males and females, if for no other reason than that I could use it in my D&D campaign.
