That play works if you are in fact a PhD in a related field, but not if we're both reading the same study as laypersons and disputing its relevance and reliability. What I suspect happened here is that you found this study by Googling for it, and forgot that it is in fact very easy to get a capsule summary of any published study posted on HN.
