People rarely link to research on this site or any other. It's a social network. People want to share their opinion and so they do. I cant remember the last reply to a comment I saw on here that actually linked to research.
That's generally true, but one common practice that originally drew me to HN was the frequent use of [#] citations by commenters to support their remarks with external sources. So in replies to a user specifically asking about research and evidence for these risks, it's disappointing for me to not see any research or evidence.
