The tl;dr is that the Baymard institute publishes something on Medium limiting its distribution, the UX for finding out what the institute has to say (if you cannot read the article) is - read some blurb on Medium, search for name of institute to find website, go to website and decide if what they have to say is useful for you - or in the case where you go through HN or some other commentary on the article reading the comments first before searching for site.
