I think, the new Pubmed layout isn’t too bad. But there is a remarkable difference how papers are being displayed right now. Justif compare the old (legacy) version of Pubmed and the new layout using exactly the same search query.
I fear that the new sort order will let a lot of scientists just take the “best match” as their main reference – also known as Matthew effect. The NLM support didn‘t understand my issue
Thank you for writing to the help desk. The default sort order is Best Match to help users find relevant citations quickly. If you would like to change how results are sorted, please use the Display Options button (located in the top right corner). If you change the “sort by” option, your new selection will be active for subsequent searches until browser data and cookies are cleared. For more information about sorting your results, please see: https://pubmed.ncbi.nlm.nih.gov/help/#sort-results.
I fear that 90% of all Pubmed users will now go for an obscure „best match“ that may be outdated.
