I did not intend to rebut! I saw you downvoted for no given reason (as so often these days on HN) and wanted to support your comment. People interested in this topic will have no problem finding the relevant studies, which is why I didn't even bother to include links.

I just wish people didn't abuse the downvote button so often. Instead of pushing irrelevant or toxic comments down, it's used to punish differing opinions. (Sorry for the offtopic rant)
