<p>The anecdotal/systematic sentence is written incorrectly in the post above (which is why impressionistic and analytical work in that sentence). The real sentence talked about gathering evidence in ways that were spoken but not very scientific (but I can’t remember from where—folkways???) in the very beginning, so “such anecdotal evidence” had to be tested in a more “systematic” way.</p>
